Clamp systems and methods for pile drivers and extractors

摘要

A clamp assembly for securing a vibratory device to a pile comprising a frame, first and second clamp members, and an actuator. The frame is adapted to be secured to the vibratory device. The first clamp member is supported by the frame and comprises a first engaging surface defined by a first surface layer formed of carbide alloy material. The second clamp member is also supported by the frame and comprises a second engaging surface defined by a second surface layer formed of carbide alloy material. The actuator is arranged to displace at least one of the first and second clamp members such that first and second engaging surfaces engage the pile such that the pile is gripped by between first and second clamp members.
