を特徴とする油圧はつり機。 A plurality of chisel insertion holes are drilled in parallel in the front cap connected to the front of the cylinder of the main body of the chisel. In a hydraulic lifting machine in which each chisel is fitted so as to be slidable in the axial direction, a slide hole is formed in a part of each chisel insertion hole, into which the enlarged diameter part of the chisel is slidably and tightly fitted. The front side of each slide hole of the lever is formed with a gas chamber filled with gas that urges the enlarged diameter portion in the return direction, and the front cap is provided with a gas passage communicating with each gas chamber. A hydraulic lifting machine characterized by forming.
