Abstract

PURPOSE:To obtain a noiseless pile driver by using a system in which a monken is hung down through a compression coil spring and an elevating rope in a window-closed driving chamber and the monken is dropped by gravity and the spring to strike the head of a pile through a buffer material. CONSTITUTION:A driving chamber 1 is made up of a lower stage ceiling plate 2, a lower stage side plate 3, and a cap 6 housed with the head of a pile 5. In the driving chamber 1, a monken 10 is supported in a vertically movable manner through a compression coil spring 11 and an elevating rope 28, and the pile 5 is driven through a buffer material 9 by means of the monken 10. The monken 10 is vertically moved by a roller 28 wound around a normally or reversely rotatable winding plate 23 inside a machine room 14 above the lower stage ceiling plate 2, and its driving force is transmitted by a motor 18 inside the machine room 14. When an upward force and a downward force act on the driver, backward action is inhibited by a backward action preventor, e.g., a strand 44 and a holding metal tool 45.
