ンクリートポンプのビストンストローク調整装置。A hydraulic cylinder has two chambers each divided by a piston. One chamber is connected to each other by a pipe to form a sealed circuit, and the other chamber is supplied with pressure oil from a pump to reverse both pistons. In a hydraulic concrete pump configured to reciprocate in the direction, a valve is provided in the middle of the piping that supplies hydraulic pressure into the sealed circuit on the rod side of the hydraulic cylinder, and one side of the piping that discharges the hydraulic pressure is connected to the sealed circuit on the rod side of the hydraulic cylinder. A piston stroke adjustment device for a concrete pump, characterized in that a relief valve and a check valve are provided in the middle of the other piping to the tank, and the piping is connected to a hydraulic supply pipe.
