@@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 !
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?
@@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.
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?
@@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. 😉
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.
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.
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!
very great job for your using ProDrill hydraulick rock splitter to breaking and splitting huge blocks granite . Congratulations...wish you successful enterprises and achievement
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?
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.
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.
@@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.
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
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.
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.
@@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.
@@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.
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.
@@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 😅😔
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.
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.....
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 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.
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.
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.
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.
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.
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 .
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
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
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.
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!"
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.
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...
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 - ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-ZBZMkzV7neE.html
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.
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.
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. 😂
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.
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
