- When faced with the challenge of breaking very hard rock, the type that can not be broken with and excavator mounted breaker, one is left with few options. Explosives are often the quickest and most effective solution but sometimes this not desirable. One option that may be suitable is a hydraulic wedge type splitter, this tool works just like the old trusty plug and feathers but hydraulically powered.

Hey! Don’t diss on my favourite martian!
Like the new toys, I was really surprised just how nice that granite looked freshly split compared to the outside of the boulder.
Nice isn't it, I just need a diamond wire saw to slab it.
@@demolitiondavedrillandblast Someone's mind is ticking over I see! ;-)
@@demolitiondavedrillandblast Going into the counter top business? Or monumental masonry?
Expanding your service options to the area. The second one you split, the color of the rock was amazing. Thanks for sharing.
Wish I could cut it into slabs Rich.
@@demolitiondavedrillandblast I'm surprised that if you deal with demolishing boulders then maybe you should look up some of those that collect rocks and stones and those that make slabs because some of them might want some of these. I watch lots of videos on cutting Stone.
If we gave Dave an unlimited budget he could split the planets. HA HA HA.
Split the atom.....
Watching you remove all these rocks is so strange to me. Here in Houston, Texas if you want rocks like these in your yard you have to have them hauled in from a few hundred miles away.
And I bet they cost heaps.
@@demolitiondavedrillandblast Damn right. Freight is per pound, delivery means hiring someone with heavy equipment to move something that large. Large yard rocks are something of a status symbol most places in the US.
@@wtechboy18 "status symbol" lol. the Japanese garden masters used levers, fulcrums, mules and twisted bamboo rope for winches.
Yeah it is pretty stupid to spend money getting rid of a rock just sitting in your garden.
Great technique Dave - enjoyable to watch. Impressive forces at work for sure - ''high-tech" plugs and feathers!
What a super little drill rig.
Yeah, another useful tool in my box, I'm going to replace the current connections and fit dry break ones though. The little drill rig has paid for itself many times Chris.
Dave,
That will be really useful on jobs you can't blast.
But, I'm thinking that's pretty cost effective compared to explosives.....
It may not be as fast on large scale jobs, but hey their not all BIG JOBS.....
There are definitely jobs where this is just what the doctor ordered.
Surprised the "Rocks have feelings" brigade arent after you. Lol love your videos. Very satisfying indeed.
Oh... the rock huggers are out there John.
Just gotta love those new toys, it was very satisfying when I heard the big "POP" as the rock cracked.
Satisfying for me also Dennis.
This job looks like it was a lot easier on your back vs hand drilling. It looked like after those early holes, you realized you didn't need to drill as deep - save time and the drill steel by only going as far as needed on those later holes. Nicely done - the pop as they let go was satisfying.
Machine drilling is always good.
Where's the kaboom? There was supposed to be an Earth-shattering kaboom!
not q38
Amazing to watch how easy hydraulics does the job .
Thanks for posting .
You bet, never ceases to amaze me.
Nice toy makes short work of breaking rocks without you having to do the hard work.
I read the description.
Yes, thanks, glad some people read the description.
@@demolitiondavedrillandblast I had a good idea what it was before reading the description to confirm what I was thinking.
Those tools should open new low risk opportunities. Is the break predictable or does the rock still fool you.
The break is largely predictable Greg.
Nice bit of kit, there. I know it wasn't cheap, but the damn cracking goo is pretty expensive, too, and it ain't reusable!
The cracking goo still wins on the very long holes though.
Hello Dave glad to see you back. That's a really cool toy .Thanks for sharing it
You bet, thanks for watching Bob.
Very impressive machine! Nice immediate option to the "cracking goo"
Sure is Russ, just hope it lasts the distance.
What a great new money maker. Not only can you bill for the demolition work, but if you plan it right, you can split slabs for stairs, walls and walk ways and sell back to the owner.. haha.... Very nice new toy!
That's the plan!
Morning Dave, or rather evening in your case.
That has to beat using the goo on time & plugs & feathers on time & sheer physical effort.
ETA What sort of pressure's being applied by the splitters?
@keith moore I
Not the pump's pressure, rather the side load it's capable of exerting to the wall of the hole.
The limit pressure on this power pack is 6000 PSI and the splitting force is about 350 Tonnes.
@@demolitiondavedrillandblast Thanks for the info matey.
No wonder it does the job so well.
That's a tad more than can be applied by the average bloke with a 4lb lump hammer. 😉
Amazing machine! Love hearing the stone pop when it splits, more please 😄👍
Will do!
Couple of years ago I bought 3 Sierra Blasters to do just what you are doing. Work quite well.
Have you had many instances of the downhole tubes getting bent or the other hardware being damaged by rock movements??
@@demolitiondavedrillandblast No, Use carpet remnants to prevent fly rock slot the carpet and insert the tube through the slot and tether the units with safety lines anchored into any rock above or any convenient. Have anchored them on overhanging limbs of trees. I bought them to break up large boulders/glacial erratics in my fields. They are a nuisance to plow around. I lease my land and the more tillable land I can make available is good for all concerned. Laurentian granite brought down by the glaciers and left behind when the ice age ended. Have also used it for removing ledge on access roads. some rock has too many voids and this system won't work if there are fissures or pockets hidden. If you feel the drill hit a void. can cause a problem. If it will hold water it may still work as the water is not compressible.
@@sportclay1 What size hole are you drilling, from what I have seen it looks pretty small like 10mm 3/8 inch and how deep??
@@demolitiondavedrillandblast 3/8" minimum depth 6" or you have a greater risk of fly rock. I use drills up to 24" drill in steps , start with short drill then 12" or 18" + to desired depth. Basically the same pattern you are using. holes closer together. Sort of nibble the rock down. I have broken some big boulder with just the 3 units. but drilling a line of hole like a feather and wedge. Break in half then split it again. Here I don't have to get a blasting permit and hire an expert like you for this system. Friend borrowed it to remove bed rock intrusion in the cellar of his downtown home. When the house was built in 1860 He was remodeling the cellar and needed to remove the rock. Limestone. Neighbors never new. Sierra Blaster web site has some good videos.
@@sportclay1 Thanks for the info #1, I have looked at the website an YT videos, looks like a useful but I had concerns about the life expectancy in continuous commercial service.
Good idea to spread the wear over several progressively longer drills and probably fast also because of less energy loss in the shorted drills.
g'day Dave, a very useful tools to add to your arsenal.
.
looks a lot quicker than mucking about with over burden.
It has it's +&- AG
Nice work Dave. Good to see that you are saving your back and body by using the excavator mounted drill rig. The hydraulic units are just the bee's knees.
That's the plan, a lot of jobs I just can't really get the rig in though.
The power of hydraulics is awesome , great video Dave .
You got that right Ken, 6000PSI in those hoses!
That pop when the rock cracks is really satisfying.
It sure is 919
love how he takes off the mask the second he stops the drill... like the act of turning off the drill instantly removes all of the dust from the air as well...
There is hardly any dust escaping the vacuum system, the main issue is the oil vapor in the drill exhaust.
Nice toys. That sure beats drilling and driving wedges by hand.
You got that right AH.
A more controlled less volatile way of dealing with the rocks but not quite the same as blasting.
Nothing better than a new toy! Interesting how the hose going into the ram moves just before the POP! Did you notice what PSI the rock split at? Now you can do indoor swimming pools! lol.. Be Safe! Jim
Some of the rocks split at quite low pressure 2000 - 3000 PSI, a few went to limit pressure @6000 PSI
Howdy from Sacramento, Dave! A little quieter than your normal vids, but interesting nonetheless. Thanks for sharing!
Thanks for watching KP
Some of those blocks did rather seem to be trying out for someone to come, take them away, and slab them up. Good big square shapes and all.
One day I'll have a diamond wire saw Bill.
Very cool. Hydraulic feathers and wedges. Don't you wish you had thought of it first! Some of that granite was beautiful blue color.
They have been around for a long time Timothy, invented by Darda Corporation in Germany, the Genuine unit is cost prohibitive though.
How did i miss this? Oh yeah....i was stuck on ur state. I still like exploding stuff rather than forcing it to crack hydraulically.
This machine is a ripper, I was using it again today.
Looks so much more enjoyable doing your work with the drill tower. Also fun seeing it in work. And does hydraulic spliters are awsome 😁
I don't think he could drill some of those holes by hand.
@@briangardiner1015 yes you are probably correct, they look pretty big
@@MiniMachines1 Plus some were at tough angles to hold a 60# drill.
@@briangardiner1015 yes, watching his videos drilling by hand made me buy a drill tower for my mini excavators, never tried to do by hand but dosent look like fun 😅😔
Sound like Brian Gardner has done his time on a drill.
very great job for your using ProDrill hydraulick rock splitter to breaking and splitting huge blocks granite . Congratulations...wish you successful enterprises and achievement
Thank you very much and thank you to ProDrill for making a cost effective alternative.
Hi from North Wales in the UK. What a great bit of kit you have there Sir. A real nut cracker!
It sure is Steve, thanks for watching.
Wouldn't it be possible to run dose hydraulic spliters from the excavator's hydraulic aux?
That was my first thought but the splitter needs 6000 PSI and the excavator has no where near that pressure.
@@demolitiondavedrillandblast Dang, 6k PSI is no joke. Good incentive to relieve that pressure before messing with the couplers...
Just a suggestion. I would wrap those hydraulic lines in a nylon webbing. The nylon will protect the hoses from sharp rocks, UV light and if you ever burst a line you and other will not get sprayed with hot hydro fluid. Not a fun day trust me.
You will notice we stand well back when it is under pressure.
I don't know how much the explosives cost, but it must be significant with a charge and detonator for every hole. The hydraulic splitter will have had serious up front cost no doubt, but it looks like there are no consumable costs after that (other than topping up the hydraulic fluid tank now and again). Very cool, and a nice clean end product without the tons of dirt to prise the broken rock from.
They are a very high wear and tear tool Trevor, often break the wedges. Thanks for watching
Wow, a hydraulic feather and wedge, nice 👍
I need one of those for my place in northern Minnesota, I have lots of very large boulders that are too big to move.
Takes a little longer than blasting, but a lot quieter🙉🙉
Compared to blasting you get a lot less pieces of rock per hole and drilling a 48mm hole will be a bit of a show stopper for most people with only a hand drill.
HiDave, you said you were getting them. A couple of bits of advice. Make sure you drill the hole deep enough so that the wedge doesn’t hit the bottom when extended or it will bend over and not retract. The other thing is when drilling by hand don’t let the drill lean back and misalign the hole after collaring as the great pressure can bend the wedge and outer feathers to follow the hole and make retrieval difficult. They are great tools but bloody difficult to remove if stuck!
Point taken Paul, I noticed a long time ago that when drilling these large diameter holes by hand that it is best to do them myself, broken more than a few of the 45mm manual plugs and feathers in times past. I can imagine the wedge bend over would be very sad, Thanks, cheers.
Nice performance. Amazing what can be done with giant feathers and wedges. No cover dirt and noise either. But - not nearly as satisfying when it blows. 😂
They also make massive ones that are fitted to an excavator!
Those hydraulic splitters are pretty trick. Sure beat the hell out of the old feathers and wedges when it's 40c out too I bet. Though perhaps not quite so satisfying as spot of gelignite.
They are pretty good so far.
Seems like a rock like that would have been worth more to someone to have it by their custom pool than split up like that.
Good idea if you can get a large crane in and a low loader to float it out... and somebody who is prepared to pay for it.
Hiya Dave, sorry nothing beats an uncovered BOOM! But a great new toy, think of all the windows unbroken? It should save your right arm for lifting cans!!! Stay safe...Steve...
Hi Dave, welcome back. What type of licensing is required to break rocks down under? Obviously, explosives require special training and oversite but how about the goo and these new toys?
the goo and these toys require no licence, the explosive use is another story.
Do you need different drilling patterns for explosives, expando, and this new hydraulic method?
Yes, certainly Paul, these holes were 48mm and spaced up to about 500 mm apart, If I was using an expanding chemical cracking agent, 38 mm would be ideal and bring the spacing in a bit, to blast them a hole as small as 32mm would be fine and a lot less holes that an expanding chemical cracking agent.
These rocks make such satisfying thump sounds when the hydraulics bust them.
They do! I'm planning to attach a geophone and record the sound better.
That looks really sweet! The rams seem plenty heavy by themselves but nothing shakes you apart on this job like a normal drill. Anything that extends the service life of bones, joints, or the back is a good addition. :) Does your vendor do training on it or do they demo it for you and hand you the manual?
They are heavy, I paid extra to get the aluminium ones, the standard steel units would be a killer!
I like the new tooling you have. Thanks for posting this video. There was some mention about the hydraulic pressure needed to actuate this tool and someone said it was 250 psi. I think the gauge was registering in bar, and the hose specifications is SAE 100R2AT.
That hose would not be used for something as low pressure as 250 psi. Additionally my suggestion would be if you have to replace the hoses on that unit eventually, see if you can get SAE 100R6. The reason that spec (R6 ) hose is better is because it has half the bend radius of the ones that are on the tooling now so you can bend the R6 quite a bit tighter than the R2AT. The hose will probably fail at the end of the crimp fitting. The weight of the hose and pressure being applied and relieved will eventually ruin the hose where it begins to hang down at the end of the fitting. Unless otherwise damage that is a long way off however.
Thanks for that YT, the limiter is set to 6000 PSI and I'm planning to replace the crappy connectors with some flat face dry break ones if I can get something suitable, think I might chuck the Chinese hose at the same time.
@@demolitiondavedrillandblast
Another suggestion would be if you can get an adapter to turn 90° so your hose hang straight down that would be better for the hose in the long run. If you do get the flat face couplings, make sure they’re clean when you put them together and they don’t get banged around in nicked. Almost all of the coupling failures we see are caused by external damage. I would protect the male and female end of the hose quick disconnect as if they were glass. Always cap them and always protect them.
The hose you have on the equipment now should have a working pressure of 5800 psi. If I were to test that hose in a static situation it should test at twice the working pressure and the failure should come after four times of working pressure. Many times we see the failure as not a hose problem but fitting attachment problem with crimp machine that is not calibrated properly or the operator did not understand the correct procedure and measurements. Additionally it would be in your best interest to have one extra hose with you at all times in case you experience a failure and you are in no man’s land.
@@demolitiondavedrillandblast
I discovered that I entered an extra number in the specifications for the hose with half the band radius I listed it as R16 and it should be R6.
Looks good your new splitter, you will need to buy up some more hydraulic oil now as spare.
First thing I need to do is chuck out the current hose fittings and fit flat face dry break type.
A whole helluva lot quieter than your other options. At least you wont have to hammer wedges all day now.
Pretty heavy though!
Now that's a set up!!! They are slicker then cat whiskers!!! And best of all its better on your body!!! The power of hydraulics!!!!
Slicker then cat whiskers, Yes, they are "the ducks guys".
They came, they creaked, and then they split...every so quietly to the next job! nice one DDDB
Well... I cant say that the drilling was quiet Mac, the air powered hammer drills are VERY loud. Thanks for watching.
Where are you? I’m so enthralled I want to come and watch you do this in person.

I like that track drill Dave .. great tool .. we had hydraulic rock splitters we could pack underground for mine rescue . you could split huge boulders in short order with them . no kaboom .
Indeed they are very cool SS
Hey Dave, when I asked how you were the other day- I wasn't trying to crack a whip on you for any videos. Just hoping you were busy enjoying your summer and not some unfortunate reason for the absence.
Thanks for the videos and I hope all is well for you and yours.
All good.
Dave was probably busy sorting those new tracks out on the jalopy.
Would like to have seen more than just a passing glimpse of the mechanism.
Next time James.
That was covenant for the builders, just push the rubble to the side . Nice crakin good time
Amazing new toy there Dave, Beats the Goo to say the least. Don't know why, But I like the Thud it makes when the rock splits. I enjoyed it. Have a good day.
Totally agree Rich.
Awesome !!! now you got it made in the shade !!!!!!!!!
Mmmm... not sure about that, just another rock breaking option.
Hooray for the new toys, less manual labor and quicker done :)
G'day Dave or should I say good night mate 😂🥱 I like your new toys mate and great video as always 🍻
Hows Murphy doing these days.
Me staying warm and well fed.
@@scruffy6151 G'day Scruffy getting there trying to stay cool in the heat and making videos to upload.
Thanks Murphy 👍
The old fashioned way used tapered wedges against matching wedges in drilled holes to split rock. A line of holes was drilled along the split line and the feathers dropped in. Then the wedges are inserted into the feathers and tapped with a hand hammer. The rock splits quite rapidly. The hard part is drilling the holes.
I have some of them also Greg, the other hard part is getting them out when the rock does not break as you want and they get stuck real tight - th-cam.com/video/ZBZMkzV7neE/w-d-xo.html
Nice tool Dave. Maybe have bucket of fines on hand, to pour into the cracks to hold them open?
The 5mm screenings would be good.
I wonder if there is such a thing as smokeless powder powered feathers and wedges?
Hmmmmmm....
Have you ever tried expanding foam? Drill , pour the foam, come back the next morning and the boulder is all busted up. I was skeptical, but then I saw the department of transportation using it to tunnel thru a granite hillside to build a road. I was impressed.
Yes, I use lots of the stuff B11 I have a video play list on using this stuff.
I wish you would of showed us how those splitters work. It'd be nice to know what's going on as they're working.
Next time HFA
I'm in a covid hot zone, keep up the good work
Stay cool Damo.
Looks like your new toy is everything it's cracked up to be, a great option
It seems good thus far Peter.
This looks like such a cool business.
Yes, but it like all ventures, it has it's ups and downs.
Amazing peace of gear Dave great addition 🇦🇺👍
Indeed, thanks for watching Kerry.
Hi Dave, they may kill your channel most people are here for the bang
Not me... 🤭
I like a good Crack as well. 😎👍
@@janne65olsson, ho you awful, but i like you!
More bang coming this week CK
@@demolitiondavedrillandblast
😉👍
I know that machine will be put to some major good effects especially since now you don't need clean fill to cover all that area needed for breaking with explosives of those biggies! Still going to need a big old excavator / dump truck team to load the "effects!"
It is a very high wear and tear machine though JW, they regularly break the wedges and pop seals, so it will not be the first option.
Fun to watch this in action. How big of a hole to do you have to drill for those hydraulic feathers to fit in? Thanks
They will just fit in a 45mm hole if it is perfectly strait, I normally opt for 47mm.
An advantage is that unlike blasting, the rock isn’t crazed, so you can use it structurally if you want and are good enough to split it right.
Correct, blasted tone is full of mico cracks and has a bad habit of falling apart when worked, stone that is blasted with black powder is fine though.
Dave like the new tools, but can we get back to the big bang please
Certainly Lee, two more bangs this week.
Geez Dave, those lines in the Rock appear as fast as the one's in my face... 😶 🤣🤣 Now if there was Only a vanishing cream that worked as well. 😏.
👍😎
You and me both!
nice toys, i cannt imagine the forces involved to split granite like a log
This device can supply 400 Tonnes splitting force per wedge.
Great to see hydraulic at work. What would be the average pressure at the rams ? And the diameter of the rams ?
No idea about the ram diameter and hope I don't have to find out too soon, pressure is 60mpa or 8700 psi!!!!
@@demolitiondavedrillandblast If the ram was 2 inches in diameter there would be at that pressure around 27328 pound on the end of the ram. No wonder the the rock soon gives up !
It sure seems like a game changer for you excellent tool system.
Yes, gives me more options.
See you had a cracking good time.
😅
🤣👍
This job was as it is cracked up to be.
@ Mini Machines - I think that you need one of these.
ya know dave some of those pops made some pretty flat slabs you could branch off into making stone steps i know granite has no 'plane' to break on but some of those were really flat
Indeed that was some really nice rock in there, diamond wire sawing is the next toy I think.
@@demolitiondavedrillandblast people wantin the rock gone in new construction you could turn around an sell it back to them as steps an such
Awesome piece of Kit!! really like it! But.... NOT as fun as explosives!
I hear you William, but in the end it is all about solving the customers rock problem in the most appropriate way and getting paid. Thanks for watching.
Damn.. I wish I had one of those for my cave. I bet I'd make good progress then.
Very heavy to lug through a cave system and I don't like your chances of drilling 48mm holes in tight spots, I thing the usual caver blast method is probably more suitable Evan.
Would that expanding compound you used in another video have worked here?
Yes, certainly.
Hydraulic variation of the old reliable plug and feather method. Exciting? Not so much. Much quieter than the explosive route.
Yeah, they have been around a long time Richard and they are a good thing.
Nice tool! As usual well done video.
Thanks for watching Rodney.
Wow! Cool system!
👍🏻👍🏻😊
You should try some Elco splitter lube, 10 x better then Moly grease. Pricy though. I didn't like the sound of those under pressure. Too much creaking.
Thanks for the tip! the grease that I used on this job was the grease that the maker supplied and I think it was no better than cheap wheel bearing grease. I now have the very pricey Darda White grease that does seem to work a lot better.
Nice work dave.
Glad you enjoyed it PB
I bet the payoff when it breaks never gets old.
Correct!
Damn those are some big ass stones it almost look like they're cut and put in specific areas for a reason......
They were pushed there when the house site cut was done.
@@demolitiondavedrillandblast danggg those things are Soo big!
Rocks were a nice feature no way I would have moved them
Beauty is in the eye of the beholder they say.
When the pressure is near maximum could you just... whack the rock with a sledge hammer to make it split?
Possibly but I'm not very keen about standing close to hydraulic hoses with that kind of pressure in them.
Dave I really like your hydraulic helper that thing is GREAT, just a note though when the air cooled engine is at idle or just above it is not cooling properly and I don't want you to burn up the motor run it at full throttle and You will never have to bring it to people like me the Mechanic and change your first engine oil after 5 hrs of operation because that is break in oil then change per the book and if it ever doesn't want to start no worries just take the 10 mm bolt out of the carb and drain the water, it works every time!!
Thanks Hank, I had never really thought about the cooling at low RPMs. I am very happy to do frequent oil changes, more often than book recommendation, I do on everything I own and it really shows down the track.
I understand that it is the owner's decision to remove the rock, but... it was quite a nice looking rock! I would have left it there as decoration.
Oh, he has so many rocks, they are all over his property and take up a lot of land that would be otherwise useful.
what a great idear hydraulic wedgers.
They are, not a new idea though, have been around a long time but just cost prohibitive.
Someone needs to come up with a way to drill the holes in a quieter way so that jobs like this can be done with no more noise than a lawn mower from start to finish.
you can do it quietly with a diamond core type drill but it takes forever.
@@demolitiondavedrillandblast ya, I figured that the hours of cussing from frustration and boredom with the core drill would bother the neighbors more than the regular drilling noise... Lol
Dear, your work is very good I have a question Where did you buy the drilling rig?
I made it.
