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. The clamp system comprises a structural member, first and second clamp systems, first and second locking systems, and a clamp displacement system. The clamp displacement assembly is operatively connected between the structural member and the first and second clamp assembly. When the first and second clamp systems are disengaged from the pile and the first and second locking systems are disengaged from the structural member, the clamp displacement system may be operated to obtain a desired clamp distance between the first and second clamp assemblies.

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
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 ina first clamp mode in which the clamp assemblies are adapted to selectively clamp onto portions of the caisson, anda second clamp mode in which the clamp assemblies are adapted to release from the caisson;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 ina first lock mode in which a position of the clamp assemblies relative to the structural member is fixed, anda second lock mode in which the clamp assemblies are allowed to move relative to the structural member; anda clamp displacement system having a clamp displacement assembly that displaces the first and second clamp assemblies relative to the structural member; wherebywhen 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.2. A clamp system as recited in claim 1, in which the clamp displacement assembly comprises:a drive chain operatively connected to the first and second clamp assemblies; anda drive gear; wherethe drive gear engages the drive chain such that rotation of the drive gear causes movement of the first and second clamp assemblies.3. A clamp system as recited in claim 2, in which the clamp displacement assembly further comprises a first guide cable that operatively connects the drive chain to the second clamp assembly.4. A clamp system as recited in claim 3, in which the clamp displacement assembly further comprises a second guide cable operatively connected between the first and second clamp assemblies.5. A clamp system as recited in claim 4, in which the clamp displacement assembly further comprises a guide roller for guiding the second guide cable.6. A clamp system as recited in claim 5, in which:the drive gear is located on a first end of the structural member; andthe guide roller is located on a second end of the structural member.7. A clamp system as recited in claim 4, in which:at least one of the drive chain and the first guide cable extends through an opening in the first clamp assembly; andthe second guide cable extends through an opening the second clamp assembly.8. A clamp system as recited in claim 4, in which the drive chain, first guide cable, and second guide cable define a closed guide path such that:rotation of the drive gear in a first direction causes the first and second clamp assemblies to move towards each other along the structural member; androtation of the drive gear in a second direction causes the first and second clamp assemblies to move away each other along the structural member.9. A clamp system as recited in claim 3, in which at least one of the drive chain and the first guide cable extends through an opening in the first clamp assembly.10. 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, that engage the structural member such that the first and second clamp assemblies can move along the structural member, where the first and second clamp systems operate ina first clamp mode in which the clamp assemblies are adapted to selectively clamp onto portions of the caisson, anda second clamp mode in which the clamp assemblies are adapted to release from the caisson;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 ina first lock mode in which a position of the clamp assemblies relative to the structural member is fixed, anda second lock mode in which the clamp assemblies are allowed to move relative to the structural member; anda clamp displacement system having a clamp displacement assembly operatively connected between the structural member and the first and second clamp assembly, the clamp displacement system comprisinga drive chain operatively connected to the first and second clamp assemblies, anda drive gear; wherebythe drive gear engages the drive chain such that rotation of the drive gear causes movement of the first and second clamp assemblies; andwhen 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 each other to obtain a desired clamp distance between the first and second clamp assemblies.11. A clamp system as recited in claim 10, in which the clamp displacement assembly further comprises a first guide cable that operatively connects the drive chain to the second clamp assembly.12. A clamp system as recited in claim 11, in which the clamp displacement assembly further comprises a second guide cable operatively connected between the first and second clamp assemblies.13. A clamp system as recited in claim 12, in which the clamp displacement assembly further comprises a guide roller for guiding the second guide cable.14. A clamp system as recited in claim 13, in which:the drive gear is located on a first end of the structural member; andthe guide roller is located on a second end of the structural member.15. A clamp system as recited in claim 12, in which:at least one of the drive chain and the first guide cable extends through an opening in the first clamp assembly; andthe second guide cable extends through an opening the second clamp assembly.16. A clamp system as recited in claim 12, in which the drive chain, first guide cable, and second guide cable define a closed guide path such that:rotation of the drive gear in a first direction causes the first and second clamp assemblies to move towards each other along the structural member; androtation of the drive gear in a second direction causes the first and second clamp assemblies to move away each other along the structural member.17. A clamp system as recited in claim 11, in which at least one of the drive chain and the first guide cable extends through an opening in the first clamp assembly.
