PROBLEM TO BE SOLVED: To provide a pile driving machine that prevents, with a simple structure and operation, interference by a canopy on a leader during a rise and fall operation of the leader, and allows a canopy state to be determined readily.SOLUTION: A pile driving machine includes: a leader installed at a front part of an upper machinery, in a way that allows rising and falling in a longitudinal direction and swinging in a lateral direction; a driver seat installed on a side of the upper machinery; and a canopy that covers over the driver seat. A support post on a rear part of the canopy is installed on a rear side of the driver seat, and a lower edge part of the support post is connected to a rotary member disposed rotatably in a horizontal direction on the upper machinery. The canopy is configured to be rotatable between a home position facing ahead and covering over the driver seat and a receded position facing toward the side of the upper machinery, by rotating the rotary member.SELECTED DRAWING: Figure 1 |
