Hello guys .
This is an unusual hammer diesel.
It is used to drive large concrete piles to stabilize the ground. I admit that it makes an impression, both the noise and the strength it has. - Авто та транспорт
Imagine being the guy who invented this trying to explain to someone that the piston is the stationary part and the block is gonna be the part bouncing up and down! So awesome!
Hello,
It could also be the opposite, that is, the piston could descend from the top towards the cylinder, but in this system it is too light. However, there are hammers with pistons that go down into the cylinder. Other uses, certainly.
Must have been designed by a woman.
Diesel fuel instead of gun powder in a ramset 🤷♂️
If you think this seems weird look at ww1 era radial engines. Some of them had the cylinders rotate around instead of the pistons moving
@@liamschenk5893 yep, I’m familiar with some of those. I’ve seen some up at Oshkosh air venture. It’s amazing to see them even run. There’s one where the lifters are exposed and the oil slings out. Crazy.
Yes, i have a 1 cylinder diesel with no crankshaft!!
Is it broken?.........
@galewinds7696 was cementing on the hammer. It's basically a 1 cylinder diesel engine but there is no crankshaft. You have blows per minute but no actual rpm.
And what is your miles per gallon ?
and the piston is stationary, and the cylinder doubles as a 8 ton hammer
Hope they don't attract a sandworm
That would be a very big sand worm! Imagine how many worms that would attract.
Lmao
An old grandfather of a worm
This reminds me of the internal combustion pogo stick.
Hop rod!
That's pretty much what it is. Just bigger and no pegs 🤣

This is more reliable than my VW transporter, probably uses less fuel too 😂
Maintain your shit. A well maintained transporter is extremely reliable. If it's being fuel hungry and unreliable, sounds like your injectors might be going bad. Badly worn nozzles, maybe even one or more stuck open. You might want to take a look at that.
@@remcovanvliet3018 I've owned it for 5 years from new, never missed a service, covered 77k miles, always serviced and maintained at main dealer. It started using water so I took it to the service centre, the EGR cooler was leaking cost 4k for repair and had major service along with gearbox service at the same time. Engine mounts replaced due to vibration, cured for 2 months only for vibration to return, turns out it was a problem with the crankshaft, another 2.5k spent along with new engine mounts again. So forgive me for my pessimism when I don't think a VW is reliable even though I maintain my shit....
My girlfriend's 2004 VW beetle is retired to pick ur part with only 38k miles on it, piece of junk.
Are you talking about an air-cooled Type 2 bus? Yeah, they can be needy but, because they are relatively easy to work on, they can be kept in good order and reliable. Especially now that they are fetching insane prices. Geez, I remember 20 years ago I could've picked up a mint '75 VW camper for $5000.
@@BlackPill-pu4vi no, mine is a 2019 type 6. I wish it was a type 2 like you say much easier to work on and probably worth more than the very needy one I've got 😂
This is utter insanity and I love it.
It seems like it should not work but I know exactly what it's doing.
It makes my brain hurt a little!
That has to be one of the coolest machines I’ve ever seen so awesome
Something else to be close to a diesel hammer in operation. Video just does not do it justice.
HI.
You are absolutely right. Live the noise gives you goosebumps. The power delivered is impressive.
That’s a bad ass pogo stick. And I suppose for the fuel, it is very efficient at what it does. Super wonderful.👍🏻
They actually have those. 😆
There's a UA-camr named: The Backyard Scientist, who bought a 1960's (I believe) pogo stick that used gasoline and a piston to bounce you back up. But they discontinued them because there dangerous. The kickback is violent and makes people buckle there knees. He made a video on it and tested it out for himself. 😉👍
@Dusky_The_Husky Yea the explosion acceleration was just way too instant
It doesn't get much simpler than this
They still use here western canada on bridge construction they very messy with oil& grease around.😮
This is the defacto standard method. Nothing beats it for simplicity and efficiency.
That lever sticking down at the :45 mark is the fuel injector pump. When it makes contact with the base, it squeezes diesel or fuel-oil through the injector with enough force to atomize the fuel for combustion
Exact.
The process cannot be automated, it is dangerous to then stop the process in case of malfunction.
The system requires manual dexterity to allow the operator to immediately and precisely interrupt the descent of the pole into the ground. It would be easy to automate the process. But in this specific sector it is not possible.
@@thecatSimois the little balancing piece your throttle? Determines how much fuel/air is mixed in for the combustion? I noticed the more they slacked that line the higher it flew.
@@thecatSimoit’s like watching a huge version of those powered smithing hammers
@baconthevainglorious7371 That's right, the accelerator is totally manual.
You saw well.
@@thecatSimo Thank you for the explanation. I was wondering why they needed a man to do it, but now I understand.
When I was a kid I simply called this a pounder. Now I know its properly known as a pneumatic pile driver.
Brings back memories of ex GF, she use to call me "Pounder" never knew what she meant
Definitely not a pneumatic hammer
Diesel hammer / pile driver / compactor i guess depends on what aplication its used for a might big for small fence posts..😂😂
The manufacturer calls this a “guide rod diesel pile hammer”. It is also known as a pile driver. It is not pneumatically powered.
This isn't "pneumatic", it is powered by the diesel mechanism. It operates exactly like a 2 stroke diesel except instead of the piston moving and turning a crank, the cylinder and head moves and gravity powers the compression stroke.
Cylinder comes down with fresh air, the compression heats it, the fuel pops off when the temperature reaches the critical value, half the force goes into directly driving the load, the other half goes into the cylinder, and returns to heat the next charge of air, and the cycle repeats as long as the operator keeps opening the fuel valve at the right time.
I've been in the heavy equipment repair industry my entire career, but have never been up close and personal with one of these, and as such never understood what made them tick. I had the epiphany where it all clicked watching this video. Now, I'm in awe of how hilariously simple it was from the beginning. Just like another comment I saw "Imagine being the guy who invented this trying to explain to someone that the piston is the stationary part and the block is gonna be the part bouncing up and down." I was the guy the inventor was trying to explain it to. 🤣
Greta is having a fit How Dare You run this with no DEF or filter ! LOL
How dare you run this at all? You must learn to sit in a cave in the darkness and munch on bugs.
Never knew of diesel piledrivers before now. Absolutely amazing!
Nor did I. What a great idea,
I worked in a shop that had a diesel power hammer, we used it to point steel posts, it was loud, shook you right to your core to stand next to it.
I can hear Austin Powers asking: Does that make you Randy baby!😂
"THATSNOT MINE BABYYY!!! Honest. 😂
OK, that is officially the coolest thing I've seen all day, week, month
The sound of the bedframe when you take the girl home for the first time😂
Or so you're told
Together let's praise the god of industry!!!
Nobody ever appreciates how much f*cking backpain this saves mankind. I know i do.
That reminded me of my wife (who had put on a bit of weight) pounding me yesterday 😊❤
Pounding you? Was she pegging you? Right on
Where is the fuel injector? Cool video!
Скорее всего в поршне. В его донце
In the piston crown
I thought the same thing for a second. That is pretty awesome.
What gas migalge does it have ?
complies with Euro 0 emission standard
Keep body parts clear during operation!
How can i use this as my pick up line?
Imagine the feeling standing next to that machine in operation.
That's a great sound-grab for some giant robot or mech walker
Not sure greta thundberg would like that 😂
Such an ingenious design, so simple
I worked on one different then this type. I tested the injecter by smacking it with a sledge. A static test but everything worked at the jobsite.
Deisel Hammer designs are so awesome
Performance improvement suggestions, attach a large industrial fan on the hammer/cylinder part evacuating exhaust, oil and dirt away from the work area. 😂
Mpg???
I wonder how compact the earth is under the piece being driven into the ground. Makin diamonds!
Sorry to say, but the pressure (and heat) is far from what is required for forming carbon into diamond. Still, it's an impressive amount of energy and force.
Just realized it uses compression as a shock absorber . Super efficient using air.
Amazing , i never seen one like this , wow !
А армии на такой работал. За верёвку дёргал😂
Does the piston have 'rings' to seal the compression?
If so, is the cylinder significantly tapered to allow the rings in without catching?
Cylinder bore matches perfectly with piston rings. The mouth of the cylinder is slightly larger to allow for a softer entry. It's simply a traditional Diesel system, but on a much larger scale.
@@thecatSimoThanks. It's an impressive machine.
Would it work w other (bio-) types of oil as well?
Only with ones that work good in diesel engines.

Driving casing for foundation driller into bedrock
These are a common site in Asia, used widely in Malaysia where every structure sits on piles due to the poor ground conditions. Diesel hammer piles are cheap and dirty, so are the preferred option when there isn't a prohibition due to noise and disturbance.
What would happen if the fuel was not sprayed? Would the cylinder hit the piston?
Is the guy pulling on The Wire setting off air fuel charge or injecting fuel every time it comes down
exactly by pulling the rope when the cylinder is in the maximum compression phase, it takes a lot of experience to make it go fast, just as much to make it go slow.
Would like to see it, pick up the pile and start from the beginning
Where is the DPF and where does the DEF get injected?
Asking for the the EPA…
in the ass of EPA i think 😂❤
It's got an emissions delete tune and kit.
Interesting design though seems kinda exposed to the elements compared with a regular Delmag style - probably OK inland but I wonder how they cope on coastal work with sea water over them.
They work just fine in coastal areas
It is practically impossible for it to fail. And iron with iron. You only change the rings, but they last a lifetime
8 tons that's insane
I wonder if the new ones need an EGR, particulate filter, and DEF system.
Let’s hope they are exempt from that madness !
Adds whole meaning to hit and miss
😂😂😂😂
This is some wild engineering
well that explains where the idea for a gas powered pogo stick came from
Not a job you wanna go to with a headache 😂
Very cool
I want one!
😮 I’m still working out what I’m seeing
That's so rad, I've been on 1 jobsite where a diesel hammer was used with a Mexican led usdot bridge crew
I thought that these hammers are powered by the crane holding it. That's a very neat design!
I worked for several years as an inspector for the DOT using the second type (and more common) of hammer in the video where the piston is moving up and down. The crane operator is running three cables - one for the pile hammer leads (framework), one to lift the piston to start the operation, and one for the pile being lifted into the leads and driven. There is a rope attached to the fuel supply valve to shut down the driving once bearing tonnage has been reached. The bearing tonnage is predetermined for the use. It is calculated by a formula involving the weight of the piston, the height of the piston drop, and the weight of the pile itself. This gives you the necessary distance per blow to achieve the tonnage of bearing designed. So, if you calculated that a minimum of one half-inch/blow is needed, you mark the pile and count 10 blows, mark again, measure. If measured less that 5 inches, the fuel supply cut-off rope is pulled, halting the driving on that pile. It is important to halt not only for cost (paid by foot driven) but because cast-in-place piling are designed to be 'hung' in a layer of suitable soil to gain tonnage via friction. H-piling are driven to bedrock and must also be halted to avoid doing damage to the pile.
Still cleaner than a jetta
how many horsepower does it develop please?
Bore 96 cm, stroke 130 cm, displacement 94.000 HP
Wow never seen one in operation what a bit of kit you can keep your hydraulics this is the way to do it ,the tree huggers might have something to say though lol
What's unusual about this diesel hammers over others?
Hi,
They are much more efficient. They are much more powerful.
This is essentially the reason.
@@thecatSimoand here I thought all diesel hammers operated about the same.
Like in Tom & Jerry.
That’s impressive!
You are right.
But the live sound is scary..
I want one
Like me and my girlfriend when we were 17 y.o
Hope you had a higher moly grease 😂
Ah, those were the days ... hammering whole night
And 20 yrs later she's a hammered troll
What is the purpose of the person pulling on that rope as the block comes down?
He'll cut off the fuel when they're done pounding so it will stop
I knew a Hiep N Vu who did this back in 2005
Damn a Hugh pogostick
How is the fuel delivered ?
Probably by truck. A couple of Jerry cans just won't cut it.
Looks like this thing gets terrible mileage too.
No cushion block?
Air cushion
Air compressed in cylinder acts as cushion block itself.
Mantab bro
I mean, if a piston is a hammer. Based on its principles, diesel pistons technically are sort of "fuel" hammers if you directly oppose them to achieve combustion in a shared chamber
Gonna start calling diesels atom smashers
Isn't that a 2 stroke diesel?
Hi, two-stroke diesel yes.
It is an engine that today is used almost exclusively for the propulsion of ships, its cycle (intake-compression-expansion-exhaust) is carried out in 360°, i.e. one revolution of the crankshaft exactly like in two-stroke engines.
The main characteristic of a two-stroke Diesel cycle is that of having an exhaust opening (called port) in the cylinder walls (as in two-stroke engines with positive ignition), this port is controlled in opening and closing by the passage of the piston.
@@thecatSimo Great explanation. I have a piston port 2t gas engine that operates on that principle.
Though it's not done much, when these engines idle, they speed up considerably.
Reminds me of when I was young
cant see a fuel line its there somewhere 1st time seeing this
I’m very curious what it smells like. (Different diesel engines have different smells)
I dont see where spark plugs are??
HI.
you can't see it, but in the center of the piston there is a diesel injector. It is activated by the operator with the movement of the rope.
Diesel's dont have sparkplug
I hope....you're making a joke....😢
Your right, they have glow plugs. @@wadewilzon
This should be adopted in amusement parks
someone explain why a person holds the cable
Probably to disable the injector and stop it when the job is done.
Otherwise it might just pound its way to China 😅
Opens and closes injector.
If you put an automatic injection pump then it becomes a monster, difficult to control.
@@thecatSimo Coming soon to a theater near you: The Automated Diesel Pile Driver that destroyed Cleveland.
Roughly how much diesel does it consume? Per hour, I assume.
Wouldn't you prefer it in mpg?
Дизель молот старый добрый анохронизм, почти полность вытеснены гидравлическими машинами.
" And that, kids, is how I met your mom"
I could stand there all day. How much does it pay ?
So there's combustion as it's compressed? 🤔
Yes. It operates on the same principle as a diesel engine but instead of turning the crankshaft it hits piles with a hammer.
I’m a truck mechanic so I don’t really know much about construction, but what’s the purpose of the guy holding the rope?
HI.
With the rope the operator activates the spray of the diesel injector. It would be easy to authorize, but if the injection mechanism were to fail, the hammer could blow up, it's very dangerous. It has already happened that it went out of control and hit and destroyed the concrete pole with very long consequences and recovery times. We chose to control the injection manually.
@@thecatSimo Wow must be skilled to control that thing. Diesel engines in trucks have been computer controlled since the 90s and there’s a mechanical governor before that. So the driver is technically never in full control of fuel injection

È stupendo nella sua semplicita!🇮🇪✌️
Questa è vera tecnologia!
Typical VW TDI Sound
У нас это называется "Баба Копёр".
Никто мне до сих пор не смог объяснить, почему именно так :/
Diesel hammers are awesome, we still use old drop hammers where the operator brings the hammer up on his whip line and lets it drop.
Looks like 8 megaton.
Oh sure, I know how these things work - I have plenty of experience with them in Borderlands 2!
I should call her
That fucking awesome. Love the video
I guess you can't just fire it up on the test stand to see if it works..
I guess there is No need to Test this thing. It Looks Like the Most Basic compression ignition engine you can build.
