PURPOSE: A device for inspecting a hydraulic cylinder is provided to prevent the damage of the hydraulic cylinder and an oil leakage by precisely inspecting the hydraulic cylinder. CONSTITUTION: A device for inspecting a hydraulic cylinder(12) is composed of a fixed base(14) fixed to a rail(10) and supporting the hydraulic cylinder, a movable base(18) installed at the front of the fixed base, a measuring unit measuring the stroke of the hydraulic cylinder, cushion valves(22) installed at a cover(20), pressure sensors(24) installed at the cover, a PLC(26), a computer(28) controlling the PLC, and a monitor(29). The PLC calculates signals received from the pressure sensors and the measuring unit, and regulates the pressure of oil supplied to the hydraulic cylinder.
