ABSTRACT:
The non-impact pile driver of this invention comprises a mast mounted on a trailer chassis and a carriage guided by the mast for vertical motion along it and comprising a hydraulic ram with a downwardly projecting piston rod. The carriage is raised and controlledly lowered by means of a winch. Horizontally movable latch members on the carriage, operated by remotely controllable hydraulic actuators, engage abutments on the mast, at spaced intervals along it, to lock the carriage to the mast. Thus the carriage can be lowered in stages for driving a substantially long pile.
