Filed:

Sep 29, 2006

Appl. No.:

11/540250

Inventors:

John L. White - Kent WA, US
David Yingling - Covington WA, US

Assignee:

American Piledriving Equipment, Inc. - Kent WA

International Classification:

E02D 7/00

US Classification:

173 90, 173184, 173 1

Abstract:

A clamp system for an elongate member, comprising first and second clamp members, an actuator member, and an actuator system. The actuator member defines an actuator cam surface and is supported for movement between first and second actuator positions. The second clamp member defines a clamp cam surface and is supported for movement between first and second clamp positions. The actuator system displaces the actuator member between first and second actuator positions. As the actuator member moves from the first actuator position to the second actuator position, the actuator cam surface engages the clamp cam surface to cause the second clamp member to move towards the first clamp member, thereby clamping a portion of the elongate member between the first and second clamp members.

International Classification:

E02D 13/00

US Classification:

405232, 173171

Abstract:

An adapter assembly for transmitting a drive force from a pile driving system defining a drive axis to a pile defining a pile axis comprising a base assembly and an adapter assembly. The base assembly is operatively supported such that the drive force is transmitted to the base assembly. The adapter assembly comprises a plate member, a skirt member defining a skirt chamber, and an adapter connector configured to support the skirt member relative to the base assembly, the plate member, and the pile member. The adapter assembly substantially aligns the drive axis with the pile axis. The drive force is transmitted from the base assembly to the plate member. The pile is received within the skirt chamber such that the drive force is transmitted from the plate member to the pile. The skirt member is substantially isolated from the drive force.
