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.

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.

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. 😉👍
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.
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."

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.
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.
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!
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.
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.
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.
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
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.
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.

Bro got the 1,5 cubicmeter diesel
Does the piston have 'rings' to seal the compression?

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.

Why you need the guy with the rope - can’t it be automated ?
It's an emergency switch. It possibly could be automated but a guy with a rope is more reliable and way more cheaper than anything else.
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.
And it is diesel so it is more fuel efficient
