Patent ID: 8434969

Claim:
A clamp system for connecting a vibratory system defining a drive axis to a pile defining a pile inner surface, the clamp system comprising: a frame comprising an attachment member adapted to be operatively connected to the vibratory system, and a stop ring defining a stop cam surface; a plurality of clamp members defining first and second cam surfaces; an actuator collar defining an actuator cam surface; an actuator system for displacing the actuator collar; whereby the frame supports the actuator collar and the plurality of clamp members such that the first cam surfaces engage the actuator cam surface and the second cam surfaces engage the stop cam surface; operation of the actuator system displaces the actuator collar towards the stop ring; as the actuator collar moves towards the stop ring, the actuator cam surface acts on the first cam surfaces and the stop cam surface acts on the second cam surfaces such that the clamp members are displaced away from the drive axis to place the clamp system in an engaged configuration; and the clamp members are adapted frictionally to engage the pile inner surface when the clamp system is in the engaged configuration.
