This was a good video of the bulldozer history and the mechanics of the elevated sprocket tractor current design. I was transferred to the Cat Track Type Tractor D10 design section from Cat Defense Engineering in 1976. Working as a draftsman engineering technician on the first production elevated sprocket D10 tractors, I remained in that division until I retired in September 2000. During those years, I recall doing changes and designs for production issues, assembly issues, and components. I redesigned the prototype fender to be more narrow and bolted to the rear drive case casting instead of being welded. We added skid plates to the top of the fenders and hand rails to the ROPS base. I designed the first fire suppression to be provided as an option for the tractors. I redesigned a final drive bevel gear that had a spacer plate to be a single part. I designed a ROPS base to provide a mounting for the cab and also a cross member with a mount for the cab and a firewall. This eliminated a support frame for the cab and reduced shake motion felt by the operator. I designed a pair of housings for the drive shaft to go into the rear drive case to provide lube to get to the bearing needed for that entry. In 2000, I was transferred to the pipelayer design group. We designed a machine with a hydraulic lift cylinder and a counterweight that opened like a door that did not go into production due to the hydraulic cylinder allowing a "drift" that did not keep the pipe from moving slightly, that is necessary for welding the pipe joints. I later worked on Custom Shop tractors, mostly land fill machines, that required modifications to keep wire and other debris from entering the engine area and the sprockets. We also designed and built pipelayers modified with engine and hydraulic tank heaters for use in Siberia operating on the permafrost at temperatures around minus 40F. Some readers will know that bulldozers are the Cat product most identified but there was a huge range of equipment, engines and transmissions that evolved from the beginnings of the Holt and Best merger that became Caterpillar. I hope this is interesting to the gearheads/designers, factory planners/assemblers and will add a link to a few of the remaining designers and technicians from the Cat Track Type Tractor engineering people I have contact with.
Good evening! That’s quite the career, and what I have in mind for my career path as well. I work in a Caterpillar Rebuild facility, and a lot of the innovations you designed allow us to rebuild these machines to like new condition in a relatively short time span. I’ve always been intrigued by the research and development, and engineering aspect of the tractors. In fact, a few weeks ago a coworker and I were in Hydraulics class in Irving. By the third day, I was known for taking the class off on tangents that went much deeper into theory than the scope of the course, and often resulted in us digging through schematics and enlisting the help of another instructor to find the answer. One of our classmates asked my coworker “Is he always this inquisitive?” My coworker replied “Yep. We don’t let him in the component shop anymore. Not after finding him counting the teeth on the gears…” That being said, I’ve had a few ideas for product lines I’ve thought about bringing forward. This would be a different application than what Caterpillar is known for, but I believe the powertrain systems hydraulic systems, and even existing product lines could be utilized to be very competitive in the industry.
I'm very surprised to find out you think this video was good, this video had very generic and inadequate explanations like you'd find in a textbook. I am disappointed i didn't learn anything about this amazing piece of equipment.
as some one that knows nothing about heavy equipment i just have to say cat makes the most beautiful equipment out there. if i had a dollar for every hour i spent sitting on the side of a hill watching cat two engine scrapers being pushed by cat D10 s i would be rich. i have been watching cat machines working all my life, from a little boy selling lemonade to the operators ,to working for a rail road as an electrician maintaining cat generator sets and locomotives , to now retired at 75 looking on the internet at them. i still get goose bumps seeing and hearing the roar of power from that screaming engine under load and the ground shaking under there massive weight . i love it and now seeing them being put together is just great. thank you for this video ,
Fabulous. Spent some years up hill and down hill clearing and leveling, cleaning and harrowing, land development, on a D6C and memories of that season will always remain. Magnificent machine.
There is something primeval about the D11. Its very impressive and intimidating at the same time. This machine has literally changed the face of the earth. Its a massive animal.
That’s how I love to think of these things. Some great beast. If a car is a modern horse then this D11 is a dinosaur. Makes the thought of the remote control ability shown at the end all the more unappealing. Riding a dinosaur is always more fun than just telling it where to go and what to do.

Enjoyed the look at the D11. I had a great experience back in the 60's when CAT was trying to upgrade the D9 into a bigger machine. They built the SXS D9's with a 20' blade across the two D9's. I got to drive one at a strip mine in west-central Indiana. They were spreading topsoil back on the spoil banks after they were leveled. The operator sat on the right machine. The machines were connected by 64 wires that transferred the control inputs made by the operator. It was a little light in weight to handle the 20' blade but with finesse it worked pretty good. WOW what a ride!!!!!!
Awesome story man! It's crazy how a 20' blade is something that can be upgraded on. Most people don't even realize how impressive these machines are until they step in front of one.
Thank you for this video. My STOCK in CAT grows each month even when the Market is going Down hill. My Personal Machine is a 1978 Dynahoe-190 BE. That CAT bought out that 100 booming years Company. I am so happy with what CAT is doing for the Future. They are so Advanced in development.
I was a D11 operator for 11 years , such a smooth machine . I pushed coal on a coal yard. I turned a d10 T2 over on its side on the side of a coal pile and was able to turn it back over without any help !
Thanks for the stories man, we love hearing first hand accounts. The D11 is a beast to be sure, and we can imagine how cool it must've been to watch that D10 get flipped
We had D9's and a D10 in our coal yard. Seen a couple D9's go on their sides. Thankfully never had the fun of doing it. Went off the pile sideways but got it turned before it rolled. Did it for 14 years. Wish I could do more. But they closed the coal side down.
@@billygriffith8933 let off the D celebrator pedal , giving it full throttle I went forward and reverse until the tracks dug a hole and it was able to set up on its own, and I didn’t mention the track come off of the rear roller and was rubbing the counter weight. But I was still able to drive it around to the tractor shed so the mechanics could fix it. By the time I got it around to the front side of the coal pile the track was hot enough to burn you from rubbing the counter weight .They had to take tension off of the track to get it back on the rear roller . The bulldozer was brand new they could not figure out how I tore the track off and I never told them 😂😂😂😂
i rode a D65 E kamatsu dozer straight off a 35 to 45 feet inverted rock vertical. landing on 2 light loads of topsoil that i pushed off a minute before under that load was solid rock. wearing no seatbelt, i was equipped with a ROPS that got bent down to the operators seat. the tractor turned over 1 time and landed on it's top, then sprung back over on its tracks. the dozer was running wide open and in second gear and wasn't moving, except for the oil that was blowing out of the turbo that was separated. what my injuries were: a severely burnt palm of my left hand ( had to of been from the smoke stack quite a ways away from the operators seat, my back had scratches around my belt line. my face and forehead was pack in dirt. no injuries that kept me from getting back up on the hill on monday, it happened on a friday. i was attemting to leave a pile at the edge of the top and then to push it off with the next load, the owner of the company was standing far enough back to start waving me to push it off, i did and nearly crapped my drawers when i sluffed of the dozer blade. i backed up and pushed a second load also starting to back up, and owner was waving me to push it off i did and when i put it in reverse, i must have hit 2nd or in between gears if it's possible, and let off the decelerator and it was in slow motion going forward by the click of growsers or what the track cleats are called, "click, click click slower that 1 second intervals and as the idlers were nearing the edge i froze and squeezed the clutches while screaming "im gonna die" over and over. i was 18, iwas the loudest and roughest thing i've ever been in. i had to of missed me by inches, i ran out of the dust cloud and went up to owner and said "well it doesn't look like you need a operator like me, he said he couldn't believe i wasn't dead, and he ran up and shut the dozer off. i had never worked in the hills before, only in the flat lands with fills no more than 5 ft, pulling a vibratory sheepsfoot. and if you want to change directions, you didn't need the brakes because the roller stopped the tractor immediately. to have corrected the fall all i had to do was put my foot on the brakes. i didn't know about that. monday moring a 988b was loading 40 an hour the owner said if i don't get up there, i might develop a fear for hills and never be able to do it again, and i wouldn't get less than 4 piles away from the top edge, the insurance totaled the dozer and the loaner dozer from kamtsu was with street pads and a four in 1 bucket, with no seatbelt. but brand new tractor and rops of course it was around 1979. i went on to a full career running scrapers, 666's 657's, 637 was my specialty, rough but they'd go anywhere. . in the hills of sounthern californa iuoe, didn't file any kind of injury lawsuit, the owner took me to the hospital and in a couple of hours i was getttin a ride back to my truck. sittin in a deep seat, both feed flat on the floor with a far away look, i was a dirt diggin mofo.
Not sure where the bulk of the footage was gathered but I can tell you @12:00 into the video I was operating W88 last week in QLD Australia. These are also our dozers @14:06 and our autonomous control center. W88, W92 are a part of our 8 dozer push fleet.
That's awesome! Thanks for letting us know, it's cool to hear first-hand accounts of where the footage is found from. Keep up the great work over there!
The D11 has a larger rival from Komatsu but in all metrics, the D11 beats its rival - production, fuel consumption, and many more. It outsells the Komatsu by 10-20 to one and is made in the USA by Americans.
I found the reason for Cats success is the quality of the steel they use and cat8 bolts in every joint. Especially the fluid filled track units. When overhauling the cat tracks you saw the quality in every part that l think it’s the reason they continually last Longer than other tractors. Also spares and service is good which ensures longer life of your machine plus the fact their still working while other makes haves disappeared.
Got to run the T model a few times before I retired about six years ago,but run the D-11 R for about six years before that,I liked the R model better than the T!Also 9-R taking care of dump for 777's and capping roads with berms when they got bad!
I haul these d11’s, 657 scrapers, 374 excavators and 990 loaders regularly. All these large pieces of equipment are the easiest to move for the most part. But you definitely won’t be going fast
biggest I ever moved was a D6 for dozers and a Hitachi 300 Roadbuilder with the logger undercarriage. Highway 4 to Kennedy Lake on Vancouver Island ain't no joke hauling that shit
I worked in the Aggregate and Ready Mix industry for 20 years. Beginning in the lab and eventually operating Aggregate plants. We were given the freedom to learn more and more equipment as time went on learning from the "Oldtimers". I always enjoyed my time on a dozer. Starting with a D-9, D-10 and eventually the D-11. Ripping and pushing went hand in hand with the D-11. I wasn't impressed with D-11 when I first operated it, it seemed sluggish, I later learned it was slow acting compared to smaller dozers but had lots of torque for working in the pits. My favorite dozer was an old D-9 open cab w/ROPS it was so versatile. And so reliable.
Ideas for shows: history of cat around the world foreign country job site…2, how bout a show like this for every piece of equip cat makes… the inventor of the equip, design history, test footage of prototypes, etc… 3, history of bobcat, 4, history of Stihl, 5, history of Hilti Keep up the good work buddy, great doc this one thanks...
Yeah it might be nice having all those bells and whistles, but one thought keeps coming to mind. "The more they complicate the plumbing, the easier it is to stop up the drain".
You're not wrong! But, as much as complication can be troublesome, it's worth noting that experience is how things are made to be reliable to the max. 100 years ago, a jet turbine would be considered impossible to produce to any real degree, but look where we are today. You can look at the progression from muskets, to breechloaders, to machine guns. Time shows that the more research is done into any one thing, the more reliable it'll become.
@@LordGizmo Tell you what, you take a new D-8 with all the goodies and l'll take a old D-8 that has been refurbished to original factory specs (just to make it fair) and l'm talking with a pony motor start system, run them both for 5 years and see who has the most down time.
@@superchicken5285 Indeed, but that's because of ridiculous environmental laws that force the manufacturers to limit every drop of diesel burnt and so they have to control engine parameters with computers... A hitherto unnecessary complication.
No Mines in the mountains of Los Angeles Ca. but as a avid dirt bike rider in those mountains and seeing and traversing the fire breaks the D-8 cuts down a ridge-line I can say those machines are brutes and the operators crazy.
I, and many others I’m sure share this thought, but I’d absolutely love to see how the shay engine that pioneered the American timber industry in the late 1800’s and early 1900’s. before the shay locomotive engine, with its, for lack of a better word, ALL WHEEL DRIVE, the virgin timber that was before out of reach because of its location commonly being too far from the streams that were large enough to float the large timber to the mill. Thr shay revolutionized the American timber industry. Ephraim shay was a logger himself and he recognized the need for such an engine so he made it happen. Without thr shay, America may not have become the superpower that we were in the 1900’s. It’s a wonderfully magnificent piece of history that I’d love to hear more about. Hopefully yoy see this.
I use to install fire suppression systems on D 11s with S blade's for copper mines in Arizona and measured the width of the blade at 21'6" with a Stanley tape measure
If you can find a photo of the D10 on display in front of the Track Type Tractor building SS in East Peoria, you can see a cabinet on the left side fender. That contains the first fire suppression system put on a bulldozer. It is very simple. A halon bottle with two hoses running into the dozer. One is into engine compartment to deliver the halon. The other is from the actuation valve into the operator compartment where there is a nitrogen bottle sitting on a shelf behind the operator. When the operator pulls the release valve handle on the nitrogen bottle, pressure from the nitrogen goes to the halon valve and the halon is released. The reason this was installed and became an option occurred when the first prototype D10 engine caught fire at the build area. Probably the new systems are actuated by a solenoid with a switch or button on the operator console.
I the width of the transport is 12' wide that outside of track to outside of track. The blade is always taken off. I think they messed up on using that number instead of 21'
Holt bought the track system from Hornsby Engineering of England, who failed to sell it to their war department nor the cousins of his king, Germany. There is amazing cinimer showing three tractors and a tracked trailer.
I'm surprised that no one in the comments are talking about the Lego Technic CAT D11. I bought that set a few months ago and I'm shocked at how accurate the set is to the real thing.
👏As always, Entertaining, Informative & Flawlessly Represented. 👏 A well deserved focus on an amazing machine. I think it's not only a good way to keep the channel fresh. It's awesome to get a full history on some of the Greatest machines in the world. Bravo Lord Gizmo! You definitely give my son and I something to look forward to in the evening. Thank You 👍
I operated D11’s and before that D10’s for 30 years at a coal preparation plant on stockpiles. As far as remotely operating these dozers it will take a major upgrade in technology for this to be a success as operators need to feel how the machine reacts as coal stockpiles can have testing conditions.
Great Video👍🏽 I like how you focus on 1 Awesome machine & give great information & history on it. Personally, I would luv to see more Vids like this. As always, Big Fan & keep doing what your doing👍🏽👊🏽.
A 20hp Hornsby-Akroyd engined tractor was the World's first cataerpillar tractor, in 1905. Ray Hooley has a unique movie film of early Hornsby chain (caterpillar) tractors, filmed in 1908, including views of the Hornsby-Akroyd engined machine.
I have 12 year’s operating the D-11’s the new ones are really quiet nothing like the older rattle traps 😁 I’ve made roads, ramps, pushed on dumps, landscaping pushing over 15” diameter trees like twigs, pushing snow piles higher than the blade and of course ripping up frozen ground. After awhile you get so use to it you don’t need a anything telling you what percentage you are going up or down 😊, I watch the new employees operating them and just shake my head, they can make a hole in the ground fast if you don’t pay attention to where the blade is.
...and affordable too. It's only a few million dollars (might want to check the secondary market first but absolutely have someone who knows these dozens with you before you drop any cash on a used one, because you never know just how extreme the seller abused it).
Yea the D11 has a lot of power. I operated on in a coal yard . It was hauled in and assembled. . It had a ladder mounted on it to make it easier to get to the cab . The one I operated was not diesel electric.. to be honest it was fun to operate , especially after you learn how to make it do what . Pushing coal out and making a lift or pushing in to reclaim.
You might do a video on unusual uses of the big Cats. For example, did you know that a pair of D9s were used to haul the tugs and barges used on the MacKenzie River in Canada out of the water at the end of the season? The ways were 12 X 12 timbers, the lubricant bacon grease from the cookhouse!
Most insightfull thankyou for pointing this comperlation together for the peoaple who are potentially planing to use this style of mashean although the cost must outway the task that is intended for the use of the tractor carefully planed the outcome can benefit the contractors before the purches of such a luxury again thankyou for this display of such a wide range of tractors you have available to the public I look forward to your next instalment and eagerly antisepate the new and exciting tecknolergys coming up in the years to come as technology is coming in leaps and bounds for the ease of the operator so it will be more cost effective in times where the cost of such mashiens must be taken into account before planing to outley the cost of using THEASE sort of tractors
Did you acquire the proper permissions from Caterpillar Inc to use their footage before ripping it off the CAT products TH-cam channel? I ask because some of the D8T shots (not a D11) were mine!!
We've received confirmation from them, yes. Thank you for the quality footage! We understand that not all the footage is of the D11, but it can be quite difficult to source this much footage of one machine; so, instead, sometimes we will use other clips to show what we're describing rather than try to find exactly what we need and of the D11, if that makes any sense. Basically, if we need to show the construction/assembly of the frame/body and the process is near identical to another dozer's, we may use that other dozer's footage for simplicity's sake.
@@LordGizmo Thanks for confirming you did reach out to Caterpillar Inc to properly acquire the footage. Caterpillar has their own digital archive, and the D11 is one of the biggest machines, so there should be lots of footage available. You should then consider adding credits at the end of your documentary. Without crediting the proper sources, at the cinematographers who worked in harsh working environments, you're still claiming it's all your original footage, when you're just acquiring footage any editing it together. Please consider adding closing credits and listing out all your video source material.
@@gree7964 You're right. We should get a better bibliography set up that's more than just a list of references in the description. Thanks for your work in the field!
Seriously? At 15:36, a fake cop in a hat 2-sizes too small staring at an "alert" on a city map?? You don't really have to use ALL of the "stock footage" you find on the internet.
I work for that company, that's our autonomous control center. Anyone who comes onto the coal mine is required to meet minimum PPE standards, also the operators are required to pre-start the machines before use so hi-viz is essential for safety when working around the Dozers.
@@LordGizmo No problem! Our coal mine runs 24/7 in 12 hour shifts with around 2000 workers. When working with autonomous dozers we have to have a special designated park up area away from the main " go line " and our work area's are also restricted for safety. We are also required to carry a remote device called an " A-stop (its a remote control) " that allows us to kill the dozers with the remote if we need to. There's a lot of moving parts and personnel on a mine site so safety is a high priority..

Thanks for the vid. I'm a retired CAT person and loved my time at CAT.

How cool !!!! I ran a D7, punching logging roads in the PNW. That must have been something to push with a 20 foot blade.
I’ve worked on both crawlers . Cat. Is by far the best . This goes back to the early. 70s . Some may like komatsu . Run em a while then decide
The best dozer ever made !!! But then again, cat makes the best dozer...period !

@@rogieru8796 But now they know! 😂😂😂😂 Good job!
i rode a D65 E kamatsu dozer straight off a 35 to 45 feet inverted rock vertical. landing on 2 light loads of topsoil that i pushed off a minute before under that load was solid rock. wearing no seatbelt, i was equipped with a ROPS that got bent down to the operators seat. the tractor turned over 1 time and landed on it's top, then sprung back over on its tracks. the dozer was running wide open and in second gear and wasn't moving, except for the oil that was blowing out of the turbo that was separated. what my injuries were: a severely burnt palm of my left hand ( had to of been from the smoke stack quite a ways away from the operators seat, my back had scratches around my belt line. my face and forehead was pack in dirt. no injuries that kept me from getting back up on the hill on monday, it happened on a friday. i was attemting to leave a pile at the edge of the top and then to push it off with the next load, the owner of the company was standing far enough back to start waving me to push it off, i did and nearly crapped my drawers when i sluffed of the dozer blade. i backed up and pushed a second load also starting to back up, and owner was waving me to push it off i did and when i put it in reverse, i must have hit 2nd or in between gears if it's possible, and let off the decelerator and it was in slow motion going forward by the click of growsers or what the track cleats are called, "click, click click slower that 1 second intervals and as the idlers were nearing the edge i froze and squeezed the clutches while screaming "im gonna die" over and over. i was 18, iwas the loudest and roughest thing i've ever been in. i had to of missed me by inches, i ran out of the dust cloud and went up to owner and said "well it doesn't look like you need a operator like me, he said he couldn't believe i wasn't dead, and he ran up and shut the dozer off. i had never worked in the hills before, only in the flat lands with fills no more than 5 ft, pulling a vibratory sheepsfoot. and if you want to change directions, you didn't need the brakes because the roller stopped the tractor immediately. to have corrected the fall all i had to do was put my foot on the brakes. i didn't know about that. monday moring a 988b was loading 40 an hour the owner said if i don't get up there, i might develop a fear for hills and never be able to do it again, and i wouldn't get less than 4 piles away from the top edge, the insurance totaled the dozer and the loaner dozer from kamtsu was with street pads and a four in 1 bucket, with no seatbelt. but brand new tractor and rops of course it was around 1979. i went on to a full career running scrapers, 666's 657's, 637 was my specialty, rough but they'd go anywhere. . in the hills of sounthern californa iuoe, didn't file any kind of injury lawsuit, the owner took me to the hospital and in a couple of hours i was getttin a ride back to my truck. sittin in a deep seat, both feed flat on the floor with a far away look, i was a dirt diggin mofo.
Thank you for sharing this fascinating story , I'm glad you came out of this with minor injuries. Best wishes and God Bless.
Incredible the technology and he pure, brute strength of this magnificent machine. We can be PROUD; made in America.
All D11s are built in East Peoria, Illinois
Not sure where the bulk of the footage was gathered but I can tell you @12:00 into the video I was operating W88 last week in QLD Australia. These are also our dozers @14:06 and our autonomous control center. W88, W92 are a part of our 8 dozer push fleet.
That's awesome! Thanks for letting us know, it's cool to hear first-hand accounts of where the footage is found from. Keep up the great work over there!
we got a 1975 D6 and a 77 D8. apparently people had more arms in the 70s because running them is quite a workout with 8 sticks
Operated a D10 for years. Best machines ever built.
I'm a 71 year old grandma but these machines have always fascinated me love them
The D11 has a larger rival from Komatsu but in all metrics, the D11 beats its rival - production, fuel consumption, and many more. It outsells the Komatsu by 10-20 to one and is made in the USA by Americans.
Yup! We mentioned in the video that Komatsu makes a bigger variant, but by very little. In fact, The D11 is able to work with bigger blades.
Cats are awesome. I do miss operating mine. Wonderful machines. Thanks for the video.
Hooray for Cat, and America as well. Let's keep on building, and innovating, as this is the greatest nation on this planet.
Steven Dierkes would like a word
I found the reason for Cats success is the quality of the steel they use and cat8 bolts in every joint. Especially the fluid filled track units. When overhauling the cat tracks you saw the quality in every part that l think it’s the reason they continually last
Longer than other tractors. Also spares and service is good which ensures longer life of your machine plus the fact their still working while other makes haves disappeared.
Kamatsu 475 and Cat D-11 same material,same hours,the Kamatsu will be ready for the rebuild shop while the Cat is still producing!
@@randallstewart8487 American steel 🇺🇸
@@mauricemotors8207 True,the difference between American steel and Japanese Steel!
Awesome machine ...awesome mini documentary ...really enjoyed that ..Thank you .
Hmmmm fully automated. I think skynet will love these things
Even though this seems more like a infomercial for Cat, it was very interesting and informative.
The D11 is sophisticated
Spent the on the D11R. A far cry from the antiques I operated before that. Ha!
Got to run the T model a few times before I retired about six years ago,but run the D-11 R for about six years before that,I liked the R model better than the T!Also 9-R taking care of dump for 777's and capping roads with berms when they got bad!
I haul these d11’s, 657 scrapers, 374 excavators and 990 loaders regularly. All these large pieces of equipment are the easiest to move for the most part. But you definitely won’t be going fast
biggest I ever moved was a D6 for dozers and a Hitachi 300 Roadbuilder with the logger undercarriage. Highway 4 to Kennedy Lake on Vancouver Island ain't no joke hauling that shit
A big Caterpillar commercial but VERY WELL done! Thanks!
Before the Caterpillar D11 becomes the world largest Bulldozer, it was the Komatsu D575A-3SD who was holding the title till it end production in 2012
We will be doing one on Komatsu :)
Would rather work on a fleet of d11’s than another 575 …. They stopped producing shit for a reason
@@LordGizmo
😂
😃🤭
@@LordGizmo u up u1
They still make the 575 u havevto order 3 and wait 2 years to get them.
This documentary about dozers is pretty awesome right there nice 😊
An "S" blade is a "Straight" blade, the blade your showing is a "Cushion" blade for push loading scrapers.
Sometimes the video editors don't know the difference, but this project was like testing the water. Indeed, you will watch a better content in future.
It's a U blade buddy
The Florida pool pump motor repair guy, approved ! that was good info, thanks Lord Gizmo
I worked in the Aggregate and Ready Mix industry for 20 years. Beginning in the lab and eventually operating Aggregate plants. We were given the freedom to learn more and more equipment as time went on learning from the "Oldtimers". I always enjoyed my time on a dozer. Starting with a D-9, D-10 and eventually the D-11. Ripping and pushing went hand in hand with the D-11. I wasn't impressed with D-11 when I first operated it, it seemed sluggish, I later learned it was slow acting compared to smaller dozers but had lots of torque for working in the pits. My favorite dozer was an old D-9 open cab w/ROPS it was so versatile. And so reliable.
Ran a D11 N for ten years it was a great machine.
Great machine 👏 💪 👍 not too small or large very versatile,more likely used all over the globe 🌎.
You should sell this video to Caterpillar to use as a promotion video.
Fantastic description.
Good explanation about the machines
Thanks for the video, I love watching these videos about big equipment .
🤗👍💖💫
Great video! More of these please!
Ideas for shows: history of cat around the world foreign country job site…2, how bout a show like this for every piece of equip cat makes… the inventor of the equip, design history, test footage of prototypes, etc… 3, history of bobcat, 4, history of Stihl, 5, history of Hilti
Keep up the good work buddy, great doc this one thanks...
Yeah it might be nice having all those bells and whistles, but one thought keeps coming to mind. "The more they complicate the plumbing, the easier it is to stop up the drain".
You're not wrong! But, as much as complication can be troublesome, it's worth noting that experience is how things are made to be reliable to the max. 100 years ago, a jet turbine would be considered impossible to produce to any real degree, but look where we are today. You can look at the progression from muskets, to breechloaders, to machine guns. Time shows that the more research is done into any one thing, the more reliable it'll become.
@@LordGizmo Tell you what, you take a new D-8 with all the goodies and l'll take a old D-8 that has been refurbished to original factory specs (just to make it fair) and l'm talking with a pony motor start system, run them both for 5 years and see who has the most down time.
@@superchicken5285 Indeed, but that's because of ridiculous environmental laws that force the manufacturers to limit every drop of diesel burnt and so they have to control engine parameters with computers... A hitherto unnecessary complication.
I've stood in front of a D11R doing grading. They are huge and awesome. :)
It's the coolest machine out there...thanking my lucky stars I'm not an operator... Those jobs are going the way of the Dodo..
No Mines in the mountains of Los Angeles Ca. but as a avid dirt bike rider in those mountains and seeing and traversing the fire breaks the D-8 cuts down a ridge-line I can say those machines are brutes and the operators crazy.
lots of great old reliability and loads of new advancements, i am excited to see the electrical motors being used!
Yes in real life in this chat
I, and many others I’m sure share this thought, but I’d absolutely love to see how the shay engine that pioneered the American timber industry in the late 1800’s and early 1900’s. before the shay locomotive engine, with its, for lack of a better word, ALL WHEEL DRIVE, the virgin timber that was before out of reach because of its location commonly being too far from the streams that were large enough to float the large timber to the mill. Thr shay revolutionized the American timber industry. Ephraim shay was a logger himself and he recognized the need for such an engine so he made it happen. Without thr shay, America may not have become the superpower that we were in the 1900’s. It’s a wonderfully magnificent piece of history that I’d love to hear more about. Hopefully yoy see this.
I use to install fire suppression systems on D 11s with S blade's for copper mines in Arizona and measured the width of the blade at 21'6" with a Stanley tape measure
That’s what I was thinking. Regular 966 size wheel loader is about 10ft wide.
Hmm... FMI Morenci?
If you can find a photo of the D10 on display in front of the Track Type Tractor building SS in East Peoria, you can see a cabinet on the left side fender. That contains the first fire suppression system put on a bulldozer. It is very simple. A halon bottle with two hoses running into the dozer. One is into engine compartment to deliver the halon. The other is from the actuation valve into the operator compartment where there is a nitrogen bottle sitting on a shelf behind the operator. When the operator pulls the release valve handle on the nitrogen bottle, pressure from the nitrogen goes to the halon valve and the halon is released. The reason this was installed and became an option occurred when the first prototype D10 engine caught fire at the build area. Probably the new systems are actuated by a solenoid with a switch or button on the operator console.
I the width of the transport is 12' wide that outside of track to outside of track. The blade is always taken off. I think they messed up on using that number instead of 21'
An excellent, informative video. More please.
I work at a company that makes the steel castings for these large beasts. The center of all force, the gear cases and case side plates.
Awesome! That's great, we hope that gave you a perspective on their sheer size!
Well done. Thank you.
Very well put together history of the King..
Holt bought the track system from Hornsby Engineering of England, who failed to sell it to their war department nor the cousins of his king, Germany. There is amazing cinimer showing three tractors and a tracked trailer.
I'm surprised that no one in the comments are talking about the Lego Technic CAT D11. I bought that set a few months ago and I'm shocked at how accurate the set is to the real thing.
I know I'd love to own one myself :) It looks very cool.
Sweet documentary I kind of like Caterpillar dozers only because they don't make cletracks anymore
Keep these coming
Very informative
We plan to :)
One of the companies I work for had 1 and to say this thing is massive is an understatement got to drive it 1 day it felt so surreal
Yep. Until you actually stand next to one and if you're lucky go up into the cab you can never understand how big a D11 really is.
Caterpillar has left Illinois and is heading to Texas.
Wow wow so amazing video that for a moment a wanna be on a construction site operating a D11 😎
Who wouldn't? They're wonderful and massive machines!
👏As always, Entertaining, Informative & Flawlessly Represented. 👏 A well deserved focus on an amazing machine. I think it's not only a good way to keep the channel fresh. It's awesome to get a full history on some of the Greatest machines in the world. Bravo Lord Gizmo! You definitely give my son and I something to look forward to in the evening.
Thank You 👍
Thank you very much! We love to have your support :)
Impressive to watch in real life, for sure!
I operated D11’s and before that D10’s for 30 years at a coal preparation plant on stockpiles. As far as remotely operating these dozers it will take a major upgrade in technology for this to be a success as operators need to feel how the machine reacts as coal stockpiles can have testing conditions.
Glad to see someone likes my editing enough to heavily use it throughout their own video ;-)
I've been wanting to see this one just as well keep coming
A vidieo on the worlds largest tractor would be good. thanks
We will get one done in time :)
Great Video👍🏽 I like how you focus on 1 Awesome machine & give great information & history on it. Personally, I would luv to see more Vids like this. As always, Big Fan & keep doing what your doing👍🏽👊🏽.
What a voice this guy has. So smug yet so informative
Now that's a new one, I've heard many a description but smug is not one. Well, I hope you got to enjoy the video still :)
Great job Big Boy
Full scale Tonka toys, now that’s cool.
what a well produced infomercial
awesome doco guys. you guys always have good vids of epic machines. keep up the good work
Thank you John, we'll do our best :)
A 20hp Hornsby-Akroyd engined tractor was the World's first cataerpillar tractor, in 1905. Ray Hooley has a unique movie film of early Hornsby chain (caterpillar) tractors, filmed in 1908, including views of the Hornsby-Akroyd engined machine.
Great video. I hope you have more like this.
Thank you, they take some time to produce. We are working on getting many more like this out.
*YES SHOT*
I have 12 year’s operating the D-11’s the new ones are really quiet nothing like the older rattle traps 😁 I’ve made roads, ramps, pushed on dumps, landscaping pushing over 15” diameter trees like twigs, pushing snow piles higher than the blade and of course ripping up frozen ground. After awhile you get so use to it you don’t need a anything telling you what percentage you are going up or down 😊, I watch the new employees operating them and just shake my head, they can make a hole in the ground fast if you don’t pay attention to where the blade is.
...and affordable too. It's only a few million dollars (might want to check the secondary market first but absolutely have someone who knows these dozens with you before you drop any cash on a used one, because you never know just how extreme the seller abused it).
Yea the D11 has a lot of power. I operated on in a coal yard . It was hauled in and assembled. . It had a ladder mounted on it to make it easier to get to the cab . The one I operated was not diesel electric.. to be honest it was fun to operate , especially after you learn how to make it do what . Pushing coal out and making a lift or pushing in to reclaim.
Excellent.
You might do a video on unusual uses of the big Cats. For example, did you know that a pair of D9s were used to haul the tugs and barges used on the MacKenzie River in Canada out of the water at the end of the season? The ways were 12 X 12 timbers, the lubricant bacon grease from the cookhouse!
Good idea. I will add this to the research list
There is even a movie about this style tractor, Joe E Brown made 'Earthworm Tractor' back in 1936, and it is still a good one.
Question: how many years of experience would be required before a company allow an individual operating the Caterpillar D11?
Most insightfull thankyou for pointing this comperlation together for the peoaple who are potentially planing to use this style of mashean although the cost must outway the task that is intended for the use of the tractor carefully planed the outcome can benefit the contractors before the purches of such a luxury again thankyou for this display of such a wide range of tractors you have available to the public I look forward to your next instalment and eagerly antisepate the new and exciting tecknolergys coming up in the years to come as technology is coming in leaps and bounds for the ease of the operator so it will be more cost effective in times where the cost of such mashiens must be taken into account before planing to outley the cost of using THEASE sort of tractors
Nice mini doc!
Wow very very nice technology ❤❤❤❤❤❤❤❤❤❤
Did you acquire the proper permissions from Caterpillar Inc to use their footage before ripping it off the CAT products TH-cam channel? I ask because some of the D8T shots (not a D11) were mine!!
We've received confirmation from them, yes. Thank you for the quality footage! We understand that not all the footage is of the D11, but it can be quite difficult to source this much footage of one machine; so, instead, sometimes we will use other clips to show what we're describing rather than try to find exactly what we need and of the D11, if that makes any sense. Basically, if we need to show the construction/assembly of the frame/body and the process is near identical to another dozer's, we may use that other dozer's footage for simplicity's sake.
@@LordGizmo Thanks for confirming you did reach out to Caterpillar Inc to properly acquire the footage. Caterpillar has their own digital archive, and the D11 is one of the biggest machines, so there should be lots of footage available. You should then consider adding credits at the end of your documentary. Without crediting the proper sources, at the cinematographers who worked in harsh working environments, you're still claiming it's all your original footage, when you're just acquiring footage any editing it together. Please consider adding closing credits and listing out all your video source material.
@@gree7964 You're right. We should get a better bibliography set up that's more than just a list of references in the description. Thanks for your work in the field!
Seriously? At 15:36, a fake cop in a hat 2-sizes too small staring at an "alert" on a city map?? You don't really have to use ALL of the "stock footage" you find on the internet.
Wow! it's good those "operators" at 14:20 had there "high vis" outfits on!!!! They could have walked into each other!!!!!!!!!! lol
Hey! Safety first ;)
I work for that company, that's our autonomous control center. Anyone who comes onto the coal mine is required to meet minimum PPE standards, also the operators are required to pre-start the machines before use so hi-viz is essential for safety when working around the Dozers.
@@DynamixGTR okay
@@DynamixGTR Thanks for the info! It's hard to get a lot of that kind of info without first-hand accounts, like yours.
@@LordGizmo No problem! Our coal mine runs 24/7 in 12 hour shifts with around 2000 workers. When working with autonomous dozers we have to have a special designated park up area away from the main " go line " and our work area's are also restricted for safety. We are also required to carry a remote device called an " A-stop (its a remote control) " that allows us to kill the dozers with the remote if we need to. There's a lot of moving parts and personnel on a mine site so safety is a high priority..
thanks for the video 👍
You are welcome
amazing stuff
Your new videos are MUCH better
I like to see eskavators and dump trucks if u don't mind but I like this video too 😊

where is Bob Le Tourneau , you have half the story
R.G. claimed to have been the 1st. to attach a blade, Holt used them as tractors. R G used electric instead of hydraulics.
i have always said if i ever win the lottery i will buy me a D11 and 100 acres of land and play all day,love this machine so much
I fell asleep watching this. Good video though. Only had 2 hours of sleep the night before
