PILE PRESS-IN DEVICE AND HYDRAULIC CONTROL UNIT
To provide a pile press-in device which can increase/decrease the maximum output value as necessary and can avoid an increase in the size or an increase in the weight.SOLUTION: A pile press-in device for pressing-in a pile to the ground includes: a chuck including press-in means that holds the pile and drives the pile by a hydraulic pressure and presses-in the pile to the ground; a leader mast 42 which can liftably support the press-in means; a standard-installed rotationally driven hydraulic control valve 73 which is provided on the leader mast 42 for controlling the hydraulic pressure from a hydraulic unit 6A and supplying the hydraulic pressure to the press-in means; and a rotationally driving hydraulic control valve 731 which controls a hydraulic pressure from a hydraulic unit 6B used in addition to the hydraulic unit 6A and supplies the hydraulic pressure to the press-in means, in which the rotationally driving hydraulic control valve 731 is arranged outside of the leader mast 42.SELECTED DRAWING: Figure 9
【課題】必要に応じて最大出力値を増減できるとともに、大型化又は重量化を回避できる杭圧入装置を提供すること。【解決手段】杭回転圧入装置は、杭を地盤に圧入するための杭圧入装置であって、杭を把持し、油圧によって駆動して杭を地盤に圧入する圧入手段を含むチャックと、圧入手段を昇降可能に支持するリーダマスト４２と、油圧ユニット６Ａからの油圧を制御して圧入手段に供給するためにリーダマスト４２に設けられた標準装備の回転駆動油圧制御バルブ７３と、油圧ユニット６Ａに追加して用いられる油圧ユニット６Ｂからの油圧を制御して圧入手段に供給する回転駆動油圧制御バルブ７３１とを備え、回転駆動油圧制御バルブ７３１は、リーダマスト４２の外部に配置される。【選択図】図９
