Abstract
PURPOSE: To perform both driving and drawing of a pile simply by attaching a driver or a drawer to the tip head of an oil-pressure breaker being turned downwards without reversing its attitude.
CONSTITUTION: A leader mast 5 is supported by an arm 3 and a boom 4 connected to a truck body 2, and an oil-pressure braker 9 vertically sliding along the mast 5 is hung down from the mast 5. In case where the oil-pressure breaker 9 is used as a pile driver, a breaker rod 16 with an anvil 15 for driving a pile 10 is provided to the driver 11. On the other hand, when using it as a drawer, the drawer 12 does a drawing work by transmitting vibration generated in a cylinder 21A from striking vibration of the piston 17 of the breaker 9 to the pile 10 through a cylinder 21B.
