構成した杭の把持装置。When a booster cylinder and a booster cylinder switching solenoid valve are provided in the drive hydraulic circuit of the gripping cylinder in a device for gripping piles with a gripping cylinder, a low pressure pressure switch is activated by detecting the relief pressure of the gripping cylinder pressure. It is also equipped with high-pressure switches that operate by detecting high pressure that is dangerous for gripping, and when the low-pressure switch is activated, the booster cylinder switching solenoid valve is switched, and when the high-pressure switch is activated, the power to the hydraulic pump is turned off. A pile gripping device consisting of a lever.
