特徴とする油圧はつり機。 A flange formed near the rear end of the piston that moves forward and backward in the cylinder is slidably and tightly fitted into the slide hole of the back cap, which is divided by the flange into a first front air chamber and a first rear air chamber. each slide hole in which a plurality of chisels, each of which forms an air chamber and extends in parallel through a front cap connected to the front of the cylinder and is struck by the piston, are slidably fitted thereinto; In a part of the chisel, a plurality of chisel chambers are formed in which the enlarged diameter portions formed on each of the chisels are slidably and tightly fitted, and each of the chisel chambers is partitioned by the enlarged diameter portions. A second front air chamber and a second rear air chamber are respectively formed, and the first rear air chamber and each of the two front air chambers are connected to one another by supplying air from the first rear air chamber to the first front air chamber. A hydraulic lifting machine, characterized in that the first front air chamber and each of the second front air chambers are communicated via a communication pipe line that introduces the first front air chamber and the second front air chamber.
