とを特徴とする巻取りドラムの油圧駆動装置。 A hydraulic drive device for a winding drum for winding a rope, cable, hose, etc. into a multi-layer winding state, the winding drum connected to the winding drum being driven in the winding direction by two supply/discharge systems. A hydraulic motor connected to a hydraulic power source and a tank each having a circuit with a relief valve, and interposed in the supply/discharge circuit on the side connected to the tank of the two supply/discharge circuits for controlling the discharge pressure from the hydraulic motor. a pressure control valve with a set pressure adjustment mechanism, and a check valve that is interposed in parallel with the pressure control valve and allows backflow of hydraulic fluid from the tank to the hydraulic motor, and the pressure control valve The set pressure adjustment mechanism and the output of the hydraulic motor are configured such that the set pressure increases in conjunction with the rotation of the winding drum in the unwinding direction, and decreases in conjunction with the rotation of the winding drum in the winding direction. A hydraulic drive device for a winding drum, characterized in that a shaft or a winding drum are interlocked and connected.
