Artist Kevin Caron explains how and why he built a mobile gantry crane ....
Kevin Caron shows the mobile gantry crane he built for a water sculpture commission. He had 2 stones that didn't have flat bottoms, so he built the gantry crane to enable him to hold the stones in place as he created the metal part of the water sculpture.
But then he thought, "If I make this gantry crane just right, I could help myself out when it comes time to deliver this piece!"
Before Kevin Caron even ordered the steel to make the gantry crane, one of the specifications he needed was the inside measurement of his 14-foot trailer, because if he made it right, he could take the gantry crane for the installation. Kevin Caron realized that, if he raised the crossbar brace in each gantry crane leg, he could clear the height of the fountain's 2 stones.
When it came time to deliver the water sculpture, Kevin Caron was able to pick up both stones with the gantry crane. He turned it sideways in the driveway, and backed up his trailer right under the gantry crane. Kevin Caron had 1 stone on each side - the gantry crane is 10 feet wide, plenty big enough for the trailer.
He picked up each stone and put it into the trailer. He then took the gantry crane around the back of the trailer and right up the ramp and over the stones. He tied it down in the trailer and went to the location where he reversed the process to unload the fountain.
The gantry cranes you see in big factories are huge. The I-beam Kevin Caron used for his mobile version is tiny compared to the ones in the rafters of the big factories, with hooks the size of his head or bigger. They move on their own trolley tracks, which can span a building from side to side and move from one end of the building to the other.
How did Kevin Caron build this gantry crane? "That was the easy part," he said. He first went to the metal yard and explained that he wanted to build a gantry crane. He asked, "How big of an I-beam do I need?" They asked, "How much weight are you picking up?"
He knew he could get 2 1-ton chainfalls, so that gave him a starting point. Kevin Caron knew he was going to pick up 2 tons at the most. Still, he knew to overengineer it. He got an I-beam that will handle 4 tons. For his uprights, he used 3" x 3" box tubing with at least a 3/8" wall, maybe a little thicker. It's heavy! Kevin Caron got enough of steel box to make the uprights, with a smaller steel box for the leg cross braces. He got the trollies the chainfalls move on at either Grainger or MSC.
Kevin Caron realized, too, that he has to be able to get the gantry crane out the door. He measured to the top of the rolling garage door and made the crane about 2" shorter.
To fabricate the gantry crane, he laid out the 2 legs on his lift table and tacked it together solidly. Kevin Caron went to the local caster store and said, "I'm building a crane. I need something that'll stand up to about 3 or 4 tons." Two of the casters have locks on them to keep the crane from moving when you want to park it.
Once the the legs were in place, Kevin Caron laid the I-beam on its side on the lift table. He picked up the lift table until the legs leveled out horizontally with their feet up in the air. He tacked the I-beam to the legs, adding a heavy gusset between each leg and the I-beam to take the strain off the weld itself and put it into the I-beam and the 3" box tubing.
The gantry crane quickly became known as "Elmer Gantry" - look him up.

This man is living his life, knowing he could build anything he wants
It is a great feeling to know that I can do that. Now with the 3d printers I can do even more!
I find this video as I am designing a gantry for my strength of materials module. Thank you sir.
Glad it was helpful!
I came across some free 6x6x1/4” webbing H beam and built one completely out of that. The best thing about gantries are once built they don’t have a payment to make for them and as long as your not foolish with them it’ll last a lifetime. Great build and keep up the good work!
Thanks for watching and posting. Next on the list is a jib crane for my welding table.
This quote from your Patreon is why I love your work; " I knew I was going to pick up 2 tons at the most. Still, I knew to overengineer it. I got an I-beam that will handle 4 tons"
Well, somes good, more is better! Right?!?!?
well a 2T I beam for that span would of been cheaper and lighter and done the job so no i dont really see that being a benefit, its now top heavy and more costly with no benefits unless you can come up with a scenario where youre holding 4ton with it but keep in mind 4 ton is about what a full size dually truck weighs when empty
@@AndrewBrowner I'm building one completely out of 4" S-beam. 4" flange, 4" depth, 3/8" web. I have found the websites that find the moment of inertia and all that good stuff, but I don't understand the numbers. How much weight with a horizontal beam of 104", and the columns are 100" tall?
Good to see you again
Thanks for stopping by Steven.
Thank you so much for putting the materials in the description im going to copy this
The hardest part was standing it upright when I was done putting the wheels on.
Great job Kevin. I use bridge cranes at work a lot but the rolling gantry like yours is very versatile and convenient especially when well planned like yours. 👏👏👍👍
Thanks 👍 Andy! It's always fun to make the shop work just a little better for me.
You're quite the character...in a good way. Thanks for the feed.
I appreciate that!
@@KevincaronSculpture , I resemble your remark, my Dad would've said
I like ya style, ta
I'm building a similar unit, only two ton capacity and your design is simple and solid and best of all home built. I would paint it give it a pro look. These rigs can cost several thousand dollars, I figure about 500.00 all in. Nice job Kevin.
Thank you for watching and posting ! Was a fun build and been really helpful to have around .
Kevin thank you for the idea, I think I would like to have some boltd sections so I can break it down for storage,
Take care.
Takes a little more engineering but can be done.
@@KevincaronSculpture What I really need to do is buy a place with a good shop. That would solve things for now. Later on I will have new issues to solve.
Great project and great humor
Thanks for watching and posting.
Who would click DisLike? Another good one Kevin. Creative way to lift the finished project. I bet you were a little tense on that lift.
The hard lift was the 2650 lbs on one chain fall! Scratching my head trying to figure out why it was so hard to lift.
That's exactly what I've been wanting to build for a long time.
Easy to do and oh so handy!
very educational thanks
Glad you think so!
Always handy to have. I just built a rotating jib crane mounted behind my lathe so I can change the chucks on my Axelson 16 in.
That is on my to do list as well!
Kevin Caron, Artist well I have a 16 inch chuck that weighs over 250 lbs so that was my only option. Cool design take a trailer ball and weld it to the bottom plate. Then turn a plug with a shoulder that fits in the verticals pipe. In my case 3 1/2 in. Then use a 2” drill to drill into the plug. Perfect fit for the trailer ball. Then turn a plug that fits into the top of the pipe. Weld that to the top plate. Put grease on the trailer ball and install it. Simple and rotated like it’s on bearings. My friend has a video and TH-cam channel that shows how we made them. Steve Watkins at Work. We made 2 in a day!!!
Thanks Kevin!
Thanks for watching David!
Like your style, Kevin. Thanks for the videos. Coming in handy as I learn how to MIG weld.
Glad to help
Very very clever Kevin I love it.
Thanks for watching and posting Brad! Always nice to hear from you.
Kevin Caron, Artist thanks mate 🙏🏻
Brother this is a very helpful video thanks for sharing thanks for your time & you are a lifesaver 👊🏽
No problem 👍
Interesting build Kevin! I was interested in seeing this video to see what design choices you made. I built a gantry myself and would have liked to have seen yours prior to that build, mostly just as another data point. My choices were a bit different, but in the end our approach was the same: overkill. I ran the numbers and at 10,000 lbs weight, center load, the deflection wasn't enough to warrant concern. So at that point I figured I could support anything I'd ever need to lift and stopped doing the math. Sounds like you did something similar with your overkill approach. Thanks for describing how you lifted it, that was also an interesting element to this equation. Without mention of how someone is gonna stand your crane once built, the plan has less meaning. That lift sure must be nice to have around! Anyway, I digress. Thanks again!
nice product
Thanks, but it is not a product. It is not for sale.
Ah you make it sound so easy-peasy! Anyway something to aspire to. Might make a Mini-Elmer to start.
You can do it! Just nuts and bolts and thinking things ALL the way through before you turn on the welder.
Nice project. You have some huge stones there Sir
Thank you but they are for a different piece!
theres a program ive used before for calculating sizes for structural steel over certain spans and weights i think its called "beam boy" iirc, was a very simple and useful program
Will have to look for that! Thanks for the tip and thank you for watching and posting.
Харизматичный дядька и вообще молодец
Thank you for watching and posting.
This is my next project 😉🇺🇸
Great video!
Glad you enjoyed it
Nice video
Thanks
I would have painted it.
That is on the list of things to get done this summer.
Nice shop
Thanks.
You could load test it safely by parking a truck or tractor under it, hooking up a hanging scale & without ever lifting the load off the ground get a reading on when it starts to look under stress
I will have to give that a try! Thank you for posting this.
Excellent! Lucky you that dont have a rust problem! here (Puerto Rico) it has to be painted otherwise it would be a rust bucket in no time!
One of the great things about living in this big microwave we call home!
I've been debating building something like this, my limitation is my shop garage doors are just a normal residential doors though. Likely I would need one to be height adjustable or else disassemblable. Alternately, if I ever get that darned hvac duct out of the center of the shop I could try to install a fixed beam running the nearly 40' length of the shop.
Well, you are going to need the one in the shop to help you make the mobile one. So start with that one first!
@@KevincaronSculpture I was thinkning about dragging my engine hoist up onto the roof and using it as a sort of crane to help pull the thing upright.
Silly as that sounds, I already once strapped the engine hoist into the bed of a pickup truck to use it as a sort of poor-mans tow-truck boom to lift a stump out of a hole. It barely worked, but then again, barely working was still working.
Interesting build that young man. Just a suggestion, you could weld on four hooks, one on the bottom of each leg. Then, get some chain or steel wire and two tensioners to suit and the if you wanted to give the legs extra bracing you have a quick, easy and strong solution which can be installed or removed when you want! No charge for that idea. I have been pondering on building a gantry crane myself. It may get done? Just depends on where I am living or if I rent an industrial unit.
Good idea, but then you have that chain/wire on the bottom of the legs in the area where whatever you want to pick up can't get too now.
@@boots7859 If you had read my comment properly I clearly said they could be "installed or removed when you want". So what you are saying doesn't really hold any weight! Pun intended.
Great idea! Have to give it a look see and figure out how it would work for me.
Nice!!!!
Interesting enough, I got quite a few I-beams left over from the new Silver Bridge build after the original Silver Bridge collapsed into the Ohio river in 1967 😉
If I ever build a shop gantry it's going to be a historic event 🤣
Very cool
You have the mind to design this kind of stuff, guy! Thanks! But, contrary to the song, not all of us must get stoned...
Well it beats the heck out of "Tie me to the whipping post"!!
When one works alone one comes up with all kinds of ways to lift and move heavy stuff.
I actually want to build a small 300 pound capacity hoist that I can easily install onto my lathe ways; for lifting chucks for changing to 4-jaw or Collet and also for lifting heavier workpieces into the chuck. Commercial hoists are available, but they're uber-expensive.
And if you build your own it's just how you need it and you know how it was made! So now you can trust that it is right.
I'm just about to build a gantry crane or my workshop, it's nothing new to me, done it all before, but thought i'd look for some ideas anyway......3 mins in to this video and all changed. Does anyone know of a phone app or even simple formula to estimate what an I beam like that will carry?? I get lots of drawing to make building supports and the sizes are all calculated for me, but sometimes ( like in this job) you don't want to pay a structural engineer to calc a weight limit .
Heck, I would be interested in that app!
The calculation information is in the machinery handbook. Easy to find on ebay, amazon, msc and other locations. Beam deflection is the calc you would use. Been awhile since I wandered around in my copy of the book
good job
Thanks, a pat on the back is much better than a kick in the butt!
So, all I need is a hydraulic table to get the gantry off the floor. Brilliant.
You work with what you have on hand. Would have used a chain fall but didn't have a ladder tall enough to reach the beam overhead.
This is designed for one particular project with very specific needs like open gables, and almost unrestricted trolley travel along the beam. That all comes at a rather large cost of strength. If you are looking to build a gantry crane for engine hoisting and moving heavy equipment around. I suggest you pick a design with full A-frames and don't skimp on the gussets and reinforcements.
The heaviest load I have lifted with this crane is 2560lbs. Took a little grunting and groaning but go the job done.
depends what youre lifting and what material you have to build it with, sure a full A frame built for stremgth an gussetted could lift more but the chain falls are still only 2T, or you could use lighter material and still get the strength using full A frame, but maybe the heavy material in the high clearance design will have other benefits.. that things is way over kill for lifting anything most people have in a shop.. id be comfortable picking a car up with that thing
@@AndrewBrowner I agree with you to some extent. But would you feel comfortable moving the crane around the shop while the car is suspended from it? Like I said, dynamic loads in all directions is why you need to build for strength and stability. Lets say one of the wheels hits a bolt on the floor while you are moving a heavy load. Also there is a fair chance that not everyone watching this channel who are looking to build a crane, are quite as skilled welders as Kevin is. Which is why I suggested a simpler sturdier version.
@@GAIS414 im not someone who walks to the slowest drum beat.. if your gantry collapses because you stitched it together with bubble gum welds thats on you.. but the welds really arent the weak point they can be under cut or a little cold as long as theyre not 60% porosity they should hold true
@@AndrewBrowner If you are a decent welder/fabricator, you know best what you can and can't build and make an educated choice of materials to use. In that case feel free to disregard my suggestion. My post was of course mainly directed to those who aren't already well seasoned in the field.
What's the mesure of the I beam no what's the max weight it supoorted?
Don't remember the size of the Ibeam but I have lifted 2650lbs with it. No deflection in the beam.
Hi Kevin! I really like your video! I am going to make one as similar as possible to yours! Do you happen to have the dimensions at all? I have a 10ft tall and 10 ft wide door and would like my total crane height to be 2 inches shorter like yours, I also am going with a 9' 6" beam as I want to be able to have it straddle any trailer like yours but also if I had to, be able to have it inbetween my door. Id really like to know how long the middle and the 2 side legs are if possible. Any idea on the angle of your legs too? I appreciate it cause the guy im buying the metal from is going to cut it for free and it would be amazing to get those done by him and all i gotta do is just weld mine up! THANK YOU!
I drew it out on the floor before I got the steel. Full size so easy to get the dimensions. There were no plans per say and it was a long time ago. Sorry, I don't remember off the top of my head what the specs are.
so jelly i need that for boat motor removal big time.
Makes life so much easier! And saves your back for reeling in that monster fish!
What size I-beam is that?
If I remember correctly, it is a 6-inch beam by 10 ft long.
Can it lift 3 tons
Nope. 1 ton is all I would do.
How much was the I beam, where you bought it and dimensions please. Thx
Sorry but it's been several years. Really don't remember.
Hey man can you help me to find the casters? I am building and overkill Granty crane with 5x5 3/8 thick square tubing I bought cheap. Thanks
Give these folk a call,, www.casterconcepts.com
Cool video!
lately, I am interested in that kind of project (that helps you manage heavy things). Do you know how legal would that be?
(if it was used in a small business by welder employees) Since this is a DIY project and not a product.
To tell truth, never thought about the legal side of this. I just made it way over capacity for anything I would do.
Please what is the length of the span?
10 feet.
@@KevincaronSculpture oh ok sir thank you. I’m actually making one hope to tag you with the video when I’m done
Hi Kevin,
I am helping a friend build his own gantry crane and the one you built may work for our needs. Could you list the actual part specifications, such as lengths, metal types and wall thickness etc you used along with any other relevant parts so we can see if it will work for us? Thanks for your help!
I built this crane to fit my trailer so no plans to speak of. The I beam is 6 inch wide by 8 inch tall. The guy at the steel yard said it would hold 3 ton easy. Because I have 2 one-ton chain falls I figured that would be a good safety margin. The I beam was already cut to 10 ft long so all I had to figure out was how wide I could go with legs to keep it stable. The trailer is 4ft 10 inches wide inside the frame rails so I went 4ft 5in to make sure it would fit. Height was set just under the lowest door on my studio so I could use it outside. The uprights are 4in square steel with 3/8th wall. Again, was thinking just over engineer everything so I will never reach the crane max. Hope this helps. Thank you for watching and posting.
@@KevincaronSculpture Thank you so much! I have passed on the info you posted and it has been very helpful. You have a great set of videos that have been enjoyable and informative to watch. Keep it hanging!
Just thinking how are you getting it out the door?
Clears by 1 inch!
You tricked me, way to go.
Pricing out the steel to build my own but it’s cheaper to buy the HF gantry crane. Crazy.
Sad but true. Thank you for watching and posting.
The gussett between the I-Beam and the Legs is no where near big enough to redistribute the bucking loads. It's going to do very little to stop those legs doing the splits.
Stick in a piece of thick walled 2" Sq tubing about 1½-2ft long at 45° as a gussett would be more suitable.
Also I would have used a much larger Sq tubing for the legs, something like 4-6" medium wall Sq tube instead of that 3" heavy wall. For the leg buckling it's the larger size of the Sq that's way more important than the thickness of the tubing, within reasonable limits.
Otherwise nice Gantry.
Cheers
Yeah, it only holds about 2560 lbs before it starts to sag in the middle of the beam. Never intended to go over the 1 ton rating on the chain falls anyway. Thank you for watching and posting.
Dear sir, can you tell me the thickness and size of the pipes that you used here... And tell me the total lifting capacity... Wanna make this one for my customer...
4 inch square 3/8th"wall steel.. Not sure on the I beam but the 2 chain falls are rated to 1ton each. The most I have lifted at one time is 2650 lbs. The I beam did not move at all!
@@KevincaronSculpture Thank you for your reply sir🙂🙂...Any size suggestions for 2 ton capacity??
Hi Kevin how tall is this gantry?? Thanks!
9ft 8 inches. Just low enough to fit out the lowest door on the studio.
Thank you
Ok what I-Beam did you end up using for your 4ton and how wide is it really? It looks wider than 10' on the video.
I truly don't remember. Would have to just get some measurements and go with that. It has been a long time since I built this.
@@KevincaronSculpture I believe you. I am just interested that's all. Keep up the good work.
how did you cut the angles for the legs
Figure out my angle and cut them on the chop saw. Laid two pieces of tube on the floor and get the proper spacing to fit the trailer, get my angle from that and CHOP!
@@KevincaronSculpture thank you. love your work. am a young sculptor in england
Kevin, what is the size of your H beam?
I think it is an 8 or maybe a 10 inch beam.
Is this guy related to scotty killer!!!!
Don't know . Who is Scott killer?
Cost?
It's been a while but around $300 for the materials.
@@KevincaronSculpture
WOW!
CONGRATULATIONS!
When I search online, a 2-ton Gantry crane with a 10 foot span starts at around $2,500.00.
I would say in addition to being an artist you are quite an investor!
"God's Little Acre"
Very uplifting video.
( Where is a Keystone Cop , to write a citation, when you need one? )
It sure seems like the casters will fail MUCH quicker than anything else. You might look at what salvage yards do for engine hoists if/when they fail.
No problems so far but worth looking in to. Thanks for the idea.
You didn't ACTUALLY recorded the fabrication process?!?!😡
Happened too quickly! When you work alone most of the time, things get skipped over.
Good thinking ahead Kevin... run into any "gotchas"?
I should have put locking casters on all 4 corners. Only thing I have to change some day.
a whole lotta why, not too much how...
If you can't figure out the steps you probably shouldn't be making this.
@@KevincaronSculpture just a comment on the descriptive text, brother.
Should just bought an old fork lift
I did a few years after this video was shot.
4:37
And your point is?
@@KevincaronSculpture i would not trust those casters. Looks like proudly made in USA from Chinese materials globally sourced lol
Those casters are still on the gantry and working just fine. The crane has been to 3 jobsites and can't remember how many times outside at the studio. Just a little lube now and again and they still work just fine.
Somebody needs to show this to AvE before the lovable dolt kills himself moving heavy milling machines with a forklift or front-end loader. He's not that stupid, so he should be able to build something skookum enough for the job.
I wanna build a death trap...
HeyKevin how long a tubing did you buy for your project was that about 40 feet of 3 by 3 x 3/8 or can you share your dimensions on your gantry crane 🏗 i’m off this weekend so I’m starting this project thanks for your help I really do like that design👍🏽
Hi Harold, I think you are just about right on the length of the box tubing. As to the dimensions, I went with what would fit in my trailer. So the legs for right at 4ft on the outside and the width of the door on my shop is 11ft so I went with 10ft outside to outside.
Thanks for the comeback brother 👊🏽
