  2. Pile driver - Wikipedia

    en.wikipedia.org/wiki/Pile_driver

    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 ...

  3. Dragline excavator - Wikipedia

    en.wikipedia.org/wiki/Dragline_excavator

    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.

    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 ...

  7. Conductor pipe - Wikipedia

    en.wikipedia.org/wiki/Conductor_pipe

    It can also be referred to as a drive pipe because it is often driven into the ground with a pile driver. Conductor pipe is typically set, on petroleum wells, before any drilling operations are performed. It is usually set with special pile-driving or spudder rigs, though the drilling rig is sometimes used to save time and money. Conductor pipe ...

  8. Franki piling system - Wikipedia

    en.wikipedia.org/wiki/Franki_Piling_System

    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]

    The Danish pile-driving formula is a formula which enables one to have a good gauge of the bearing capacity of a driven pile. History The formula was constructed by ...
