Abstract
A pile driving system for driving a pile comprising a support system comprising an arm assembly, an engaging system comprising a primary housing and a secondary housing, a suspension system, a vibratory system, and first and second clamp assemblies. The first clamp assembly rigidly connects the secondary housing to the pile. The second clamp assembly rigidly connects the secondary housing to the pile. The second clamp assembly rigidly connects the secondary housing to the side portion of the pile. The tip portion of the at least one pick member engages at least one sheet pile of a substantially horizontal stack of sheet piles to remove the at least one sheet pile from the stack of sheet piles. The pile driving system drives the pile using at least one of a driving force generated by the support system and a vibrational force generated by the vibratory system.
