These pilings are not just hollow centrifugally cast, they are also pre-stressed with post-tensioned tendons. I am not sure why they go for so long with single impacts. We lived with the BNSF railroad rebuilding a bridge near our house in St. Paul MN, They were putting in H pilings about 16" across the flanges. These were 60 feet long and they would weld a second on when they got the first one in. They would start the hammer running by itself right from the start. The last 10 feet, usually with about 75-85 feet of pole down, would shake the entire neighborhood. They would e getting no more than an inch per strike and would still keep going. The foreman would chalk inchmarks on the piling once they got to a certain point.
It appears that in the beginning they were taking steps to ensure the pile was properly aligned before driving it very far (the same idea as lightly tapping a nail into lumber while keeping it aligned with your fingers, until it's okay to let go and just swing the hammer). In a lot of cases the operation of the pile driver does not become self-sustaining in the beginning because weak soils at shallow depth provide too little recoil to propel the weight high enough for it to trigger ignition on the subsequent drop, but I'm not sure if that was an issue here or not. FWIW, that marking of the piling toward the end of the process that you observed allows them to determine if there's enough resistance to penetration that there's no need to drive it farther. This degree of resistance is predetermined by the engineer. Commonly, they work with one-foot increments, but whatever the unit of measure, they keep driving the pile until the number of blows needed to drive it "one increment" is greater than the assigned value.

Drove pilings with a Linkbelt diesel hammer this hammer is backwards, the cylinder goes up and down, the linkbelt the piston goes up and down interesting.
Yes you are correct. It is a much more compact design. I suspect that weights could be added on top for more heavier hammer action?? Regards from South Africa
@@ironmartysharpe8293 It depends on engineering of stucture and soil condition. most are 75 to 150 in length they are driven to "refusal" that is a predetermined blow count per foot. Example refusal is 200 blows per foot the pile is driven when you hit it 200 times and it does not move 1 foot. There is a inspector that watches and has a machine that sits on the ground and it counts the blows. the pile is marked before fifting with 1 foot increments.
There are amazing machine monsters and technologies! Mainly because in some areas of Africa they still use clay mixed with cow dung to plaster the cane walls...
Vibro drivers are different machines relying on the weight to sink . This operative with the piece of string finally got the diesel to work smoothly ❤😊
That can happen, depending on soil conditions, though "vibration" in that case is not quite what most people would imagine since it occurs only for an instant with each blow. But the principle is the same. This does not happen once the pile reaches its design depth where penetration resistance is far greater.

interesting vidio, many thanks for posting. love this type of content✌
Thank you bro...
JAKUB
Trabalho incrível, parabéns ❤❤
Thank you bro👍👍
Amazing videos👍👍👍
Thank you brother👍👍👍
Great job ❤👏🏻👍🏻
Thank you bang👍👍👍
So it’s a glorified cylinder jumping on its piston, pretty nifty
Fascinating piece of gear. I've seen these from a distance but this is the first time I've seen one up close. Thanks for filming this.
Ok bro,thank you👍👍

Nice camera work and editing. Thanks.
Bellissimo video complimenti 👍👍👍👍
Thank you brother👍👍👍
Yea baby!
😀
Very best
Just like a piston engine, except the piston is fixed and the cylinder moves up and down. Interesting.
OK, good analysis bro 👍
Fun to listen to this without plugs.
Oddly satisfying if I do say so myself ☝️😌
👍👍👍
When they were putting the 515 extension to the middle of Las Vegas, they used one of these. I think it was in the early 80s amazing thing to watch.
Every time this thing rebounds, someone gets a killstreak with the silenced Spaz-12.
Дудум дудум дудум...😊
A BIG Nail and a BIG HAMMER!
Yes bro👍👍👍
I worked in a shop that had a diesel fired power hammer, worked much like a pile driver, wish I knew where it is now.
OK, bro... that means we both operate diesel engines...
Best wishes always from Indonesia🇲🇨
Saw that machine to plant sheet piles. BANG! BANG!
Only after the last piling was installed did they realize they were all upside down.
How ya s'posed to add a turbocharger if theres no cylinder walls? 😂
What? No EGR or DEF?!!

How does that concrete not break?
pre-tensioned and reinforced. plus has a stell cap on top.

cylinder is heavier than the piston usually
I've seen pyledrivers in action building bridges in my area , How far down do they drive those pyles

Best pile driver hammer ever

The only acceptable reason for vertical filming
Being concrete these pilings didn’t survive all the way down

아직도 파일을 이렇게 항타기로 때려 박는 곳이 있군요.
Yes, it's still used in some construction projects.
This doesn't look like wrestling at all.
How do they 8nject the diesel?
Diesel Injected thru the center of the bottom piston, when the hammer at bottom stroke it triggers a linkage attached to a pump to inject diesel
@@balachdr5 Thanks. I assume that these give a "soft" push on the pile, rather than a hard strike.
I wonder if the soil directly underneath the piling behaves a bit like quicksand from the force and vibration ?.

Where is DPF and the add Blue for this crap.
