Claims

[Scope of utility model registration request]

In a pile driving machine in which a rotary main leader equipped with front attachment guides on two sides can be raised and lowered via a sub-leader, the main leader is rotatably supported at two locations above and below the main leader. The sub-leader has a lower part supported on a support base provided at the front of the pile driver main body, and an upper part of the sub-leader supported on the tip of an undulating cylinder whose base end is supported pivotally on the pile driver main body. Guide gibs are provided at the upper and lower parts of the sub-leader in correspondence with the two holder parts of the main leader, respectively, and guide members for guiding the movement of the guide gibs are provided continuously at both the holder parts and the upper and lower holder parts of the main leader. The pile is characterized in that a leader rotation device is disposed on either one of the two holder parts, and one of the two holder parts and the sub-leader are connected via a hydraulic cylinder. Leader support device for beating machine.
