Pile driver

摘要

A hydraulic pile driver (9) including a backhoe (10), a lead (30), a vibratory hydraulic hammer (38), and a winch (46), for driving pin pile or needle pile (44) into the ground. The lead (30) is limited in height, as is the backhoe (10) in size, so that the pile driver (9) can be used within the interiors of many building structures. The vibratory hydraulic hammer (38) operates at a rate greater than 400 blows per minute and generates a force greater than 100 foot-pounds.
