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 ...
This became NCK-Rapier. The walking dragline division of NCK-Rapier was acquired by Bucyrus in 1988. The Marion Power Shovel Company (established in 1880) built its first walking dragline with a simple single-crank mechanism in 1939. Its largest dragline was the 8950 sold to Amax Coal Company in 1973.
Principle of rope-shovel operation [1]. A power shovel, also known as a motor shovel, stripping shovel, front shovel, mining shovel or rope shovel, [2] is a bucket-equipped machine usually powered by steam, diesel fuel, gasoline or electricity and used for digging and loading earth or fragmented rock and for mineral extraction.

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.
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]
As a further example, a list of machines that are preserved would probably be in order (as there won't be many of them) whereas a list of every machine made by every company is clearly taking things too far (although might be helpful on a more specific site such as the Tractor Wiki mentioned.)
