@@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 !
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.....
This one - www.rock-drill-bits.com/hand-held-hydraulic-splitter/pd-450.html and yes it was good value for money. I found this company very helpful in that they built it to order with the engine that I requested - a Honda GX270. Bottom line is that it is not a Darda but at 1/6 of the price... Make sure you order the aluminium spltters and not the steel ones as the steel ones are very heavy!
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.
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.
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?
very great job for your using ProDrill hydraulick rock splitter to breaking and splitting huge blocks granite . Congratulations...wish you successful enterprises and achievement
The hose should be able to manage the maximum preset pressure, do not adjust the pressure limiter or you may burst the hose and that could be extremely dangerous. I also strongly recommend that you buy some "Darda Grease" - should be available from any Darda splitter dealer.
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.
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.
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.
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.
Those are pretty cool tools what would be the cost of them versus explosives just curious when they do definitely have their place no flying debris no freaked out neighbors
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?
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...
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.
@@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 😅😔
Do you know how much you have to pay for rockery stone in the UK, I would give and arm and a leg for a rock that size to give a bit of interest to the garden.
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.
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
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.
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.
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.
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.
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!
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 - ua-cam.com/video/ZBZMkzV7neE/v-deo.html
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
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!"
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...
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.
Was nothing more satisfying than the sound of the granite splitting when the pressure was put on it. Nice breaks, like your "New Toy" there too. Less physical work for you. Have a day down there & be safe.
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 .
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. 😂
You shouldn't let the case of the splitter set on the rock we always put a 2x4 between the case and rock then knock it out when the splitter comes tight otherwise if the rock breaks upward it can break the case on the splitter ask me how I know
Have thought about exactly that David. The energy available is nowhere near as much as the output of this device, could be done but many more holes required and that is the most expensive part of the job.
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.
Expanding your service options to the area. The second one you split, the color of the rock was amazing. Thanks for sharing.

Not the pump's pressure, rather the side load it's capable of exerting to the wall of the hole.

They will just fit in a 45mm hole if it is perfectly strait, I normally opt for 47mm.

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.
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.
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.
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.
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.
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".
Hello friend. Can you tell me where to connect the breaker line?
I think you should ask a hydraulic specialist that is familiar with your excavator.
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.
What do you do with the drill dust ?
Do you want some?
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!
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 - ua-cam.com/video/ZBZMkzV7neE/v-deo.html
Awesome !!! now you got it made in the shade !!!!!!!!!
Mmmm... not sure about that, just another rock breaking option.
Howdy from Sacramento, Dave! A little quieter than your normal vids, but interesting nonetheless. Thanks for sharing!
Thanks for watching KP
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
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.
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.
Will the switch valve often leak oil?
No leaks.
@@demolitiondavedrillandblast Still in use for two years?
Yes, used it today. I do not use it very often though.
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.
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.
That was covenant for the builders, just push the rubble to the side . Nice crakin good time
Amazing machine! Love hearing the stone pop when it splits, more please 😄👍
Will do!
Would like to have seen more than just a passing glimpse of the mechanism.
Next time James.
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.
The power of hydraulics is awesome , great video Dave .
You got that right Ken, 6000PSI in those hoses!
Was nothing more satisfying than the sound of the granite splitting when the pressure was put on it. Nice breaks, like your "New Toy" there too. Less physical work for you. Have a day down there & be safe.
Glad you enjoyed it EB
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
Hooray for the new toys, less manual labor and quicker done :)
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!
Need a spotter for position of the drill holes?
Hi, It is fairly tedious to position it accurately
It sure seems like a game changer for you excellent tool system.
Yes, gives me more options.
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
😉👍
A very useful machine
It sure is DV! you will be seeing more of this one.
You shouldn't let the case of the splitter set on the rock we always put a 2x4 between the case and rock then knock it out when the splitter comes tight otherwise if the rock breaks upward it can break the case on the splitter ask me how I know
Oh... that would have been an expensive incident Robert, thanks for the tip.
You should post some video of your work Robert.
A whole helluva lot quieter than your other options. At least you wont have to hammer wedges all day now.
Pretty heavy though!
I was wondering about water. Drill, fill with water and flash freeze it with Nitrogen.?.
Have thought about exactly that David. The energy available is nowhere near as much as the output of this device, could be done but many more holes required and that is the most expensive part of the job.
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.
what a great idear hydraulic wedgers.
They are, not a new idea though, have been around a long time but just cost prohibitive.
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 👍
This looks like such a cool business.
Yes, but it like all ventures, it has it's ups and downs.
Is the granite dust bad to breath or something?
Not just bad Jim, it is second only to asbestos as far as stuff you don't want in your lungs.
Look up Silicosis... N95 masks are strongly recommended if you intend to continue breathing.
@@allangibson2408 N95 is the minimum standard for a one off exposure, Full face P3 respirator is a safe bet when used correctly.
nice toys, i cannt imagine the forces involved to split granite like a log
This device can supply 400 Tonnes splitting force per wedge.
How much did the job pay?
