Abstract:
1. A clamp system for allowing a pile driving/pulling system to be attached to a caisson to be driven into or extracted from the earth, comprising: a structural member adapted to be attached to the pile driving/pulling system; first and second clamp systems comprising first and second clamp assemblies, respectively, where the first and second clamp systems are supported by the structural member and operate in first and second locking systems each having a locking assembly mounted on the first and second clamp assemblies, respectively, where each of the first and second locking systems operate in a clamp displacement system having a clamp displacement assembly that displaces the first and second clamp assemblies relative to the structural member; whereby when the first and second clamp systems are in the second clamp mode and the first and second locking systems are in the second lock mode, the clamp displacement system may be operated to displace the clamp assemblies relative to the structural member to obtain a desired clamp distance between the first and second clamp assemblies.
