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.
@@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.
@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.
It's a very simple demonstration on how diesel engines work. You have fuel, you have air and when you compress the air it becomes super hot (around 3000F or roughly 2000°C for combustion moment) which then makes the diesel fuel combust like gasoline would with the help of spark, except, diesels have no spark, just compression forces.
The fuel is injected at high pressure at the exact moment the combustion is desired.Since the air is superheated because of the high pressure of the compression stroke ,as soon as the fuel enters the combustion chamber it ignites and start to build up pressure even higher, this is the power stroke. This hammer use the power stroke as a lifting method only, the actual impact spike/shock that drives the pilling in the ground is the metal to metal contact from the moving cylinder/weight on the pilling adapter. Right after this impact the explosion begins to rise the pressure high enough to lift the cylinder/weight back up. Starting the cycle again. Way faster and less strain on the crane cables, clutches, sheeves etc., you lift the weight once, then the diesel becomes a fast repeating crane. Interesting to know that these hammers never pass top dead center on the compression stroke. They are also considered two stroke diesel.
They actually have those. 😆 There's a RUclipsr 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. 😉👍
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....

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.

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."

It's rather interesting that this is literally made out of a diesel locomotive piston and cylinder but with the cylinder and head attached to make a literal pile driver. Very cool.
I hauled concrete to a site just like this for Earth Stabilizing pilings. The company then pumped the wet concrete into a slip form tube that was inserted into pre-drilled holes in the ground. The holes were deep. I never would have imagined that anyone would use a a heavy hammer like this on concrete.
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.
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.
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.
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.
The only thing bad about diesel pile drivers is when the SCR NOX Catalyst loads with soot and has to regen! They hammer nothing lightly for about an hour!
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.
No they would always be in for repairs having to do a DPF burn off with ADBLUE top up with the check engine light on needing a scan tool diagnostic code's!
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
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.
The guy with the rope is not only the failsafe to prevent runaway, but he is also a trained operator to let the stroke be large or small, according to how he times it; also to be able to stop precisely at the given mark.

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..😂😂

Probably by truck. A couple of Jerry cans just won't cut it.
Looks like this thing gets terrible mileage too.

You are right.
But the live sound is scary..
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.
That's freaking amazing..never seen one in action..
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.
How often do the piston rings need to be replaced?
Single stroke?
Where is the DPF and where does the DEF get injected?
Asking for the the EPA…
in the ass of EPA i think 😂❤
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.
