Abstract
A pile driving system comprises a lifting element attached or attachable to a hoisting cable of a crane, a pile driver which is mounted to the lifting element and movable with respect to the lifting element in a pile driving direction and a brake for braking a movement of the pile driver with respect to the lifting element. The brake comprises cooperating sliding members at the lifting element and the pile driver, which sliding members are pressed against each other in a direction extending transversely to their mutual sliding direction.
Claims25
A pile driving system, comprising a lifting element attached or attachable to a hoisting cable of a crane, a pile driver which is mounted to the lifting element and movable with respect to the lifting element in a pile driving direction and a brake configured to brake movement of the pile driver with respect to the lifting element, the brake comprising cooperating sliding members at the lifting element and the pile driver, which sliding members are pressed against each other in a direction extending transversely to their mutual sliding direction, and wherein the sliding members are configured such that a force between the sliding members is selected such that the brake keeps the pile driver at a fixed position with respect to the lifting element by static friction between the sliding members up to a predetermined force level of the pile driver on the lifting element in their mutual sliding direction.
A pile driving system, comprising a lifting element attached or attachable to a hoisting cable of a crane, a pile driver which is mounted to the lifting element and movable with respect to the lifting element in a pile driving direction and a brake configured to brake movement of the pile driver with respect to the lifting element, the brake comprising cooperating sliding members at the lifting element and the pile driver, which sliding members are pressed against each other in a direction extending transversely to their mutual sliding direction, wherein at least one of the sliding members is pressed against the other by a hydraulic cylinder.
A pile driving system, comprising a lifting element attached or attachable to a hoisting cable of a crane, a pile driver which is mounted to the lifting element and movable with respect to the lifting element in a pile driving direction and a brake configured to brake movement of the pile driver with respect to the lifting element, the brake comprising cooperating sliding members at the lifting element and the pile driver, which sliding members are pressed against each other in a direction extending transversely to their mutual sliding direction, wherein at least one of the sliding members is pressed against the other by a spring.
