When the pile driver is connected to a dragline excavator, it is powered by the excavator's diesel engine. Vibratory pile drivers are often chosen to mitigate noise, as when the construction is near residences or office buildings, or when there is insufficient vertical clearance to permit use of a conventional pile hammer (for example when ...
Big Muskie was the world's largest ever dragline. Built by Bucyrus-Erie in 1969, it was 487 ft (148 m) in length, weighed some 13,500 short tons (12,247 t), and hoisted a 220 cu yd (168.2 m 3) bucket that could move 325 short tons (295 t) of material at a pass.
Vibratory pile driver is a machine for driving piles into sandy and clay soils. Press-in pile driver is a machine for sinking piles into the ground by means of static force transmission. [16] Universal drilling machine.

In earthmoving , cut and fill is the process of constructing a railway , road or canal whereby the amount of material from cuts roughly matches the amount of fill ...
The model mathematically represents the pile driving hammer and all its accessories (ram, cap, and cap block), as well as the pile, as a series of lumped masses and springs in a one-dimensional analysis. The soil response for each pile segment is modeled as viscoelastic-plastic. The method was first developed in the 1950s by E.A. Smith of the ...
Franki piles can be used as high-capacity deep foundation elements without the necessity of excavation or dewatering. [4] They are useful in conditions where a sufficient bearing soil can only be reached deeper in the ground, [5] [6] and are best suited to granular soil where bearing is primarily achieved from the densification of the soil around the base. [4]
I also feel that the picture of the pile driver is misleading since this really is not what draglines are primarily used for. The video that I linked to gives a good illustration of how draglines operate including the fact that slacking the drag rope allows the bucket to tip forward. I do have pictures with people in them that show the scale ...
