Abstract

PURPOSE: To provide a pile driver excellent in stability by a method wherein the folding of the lower portion of a pile driving leader, the forward/backward movement of the leader, and the correction of the vertical axis of the leader can be performed singly or interlockedly, in a pile driver comprising an upper rotary body, a traveling device portion, a pile driving leader, and the like.
CONSTITUTION: On account of the nature of the expected work, a pile driver has not only an upper rotary body 1 and a traveling device portion 3 but also a pile driving leader 2 and a pile driving hammer (not shown) fitted to the leader 2, the weights of the latter two being so large that the weight and size of the pile driver must be increased to obtain a better stability. On the other hand, since the lower portion 22 of the pile driving leader 2 of this invention is foldable about a hinge pin 25 as a fulcrum, the leader 2 is rotatable over the traveling device portion 3. Further, owing to the forward/backward movement of the fulcrum portion 23 of the leader 2 and to the extension and contraction of a pair of hydraulic cylinders 4 supporting the leader 2, the leader 2 is movable forward and backward and its vertical axis is correctable. Accordingly, the pile driver can be operated in a stable condition and reduced in size.
