Abstract
A clamp assembly for a pile driving system for driving a concrete sheet pile, the clamp assembly comprising a clamp body, a first clamp member supported relative to the clamp body, and a second clamp member supported for movement relative to the clamp body, and a bumper member. A clamp region is formed between the first and second clamp members. The bumper member is supported relative to the clamp body above the clamp region. The clamp body is configured such that the concrete sheet pile enters the clamp region from below. The second clamp member is displaced towards the first clamp member to engage the concrete sheet pile in the clamp region. The bumper member resiliently deforms to inhibit direct transmission of forces between the concrete sheet pile and the clamp body during driving of the concrete sheet pile.
