Abstract:
1. A pile driving system for driving a pile comprising: a support system comprising an arm assembly; a yoke member operatively attached to the arm assembly; an arm actuator assembly operatively connected between the arm assembly and the yoke member such that actuation of the arm actuator assembly displaces the yoke member relative to the arm assembly; a coupler mount operatively connected to the yoke member for rotation relative to the yoke member; at least one lateral actuator assembly operatively connected between the yoke member and the coupler mount to rotate the coupler mount relative to the yoke member; a coupler bearing assembly operatively connected to the coupler mount; an engaging system comprising a primary housing and a secondary housing, where the primary housing is operatively connected to the coupler bearing assembly such that the engaging system rotates relative to the support system; a rotation actuator for causing the engaging system to rotate relative to the support system; a suspension system configured to resiliently oppose movement of the secondary housing within a limited range of movement relative to the primary housing; a vibratory system rigidly connected to the secondary housing; a first clamp assembly supported by the secondary housing, where the first clamp assembly comprises a second clamp assembly supported by the secondary housing; whereby the engaging system operates in the pile driving system drives the pile in at least one of the first and second modes using at least one of
