効果は、手動操作される比例動作形減圧弁の減圧状態に
応じて定められる。Via such a proportional pressure reducing valve, the pressure on the pneumatic motor is increased in such a way that the moment caused by the load is not sustained by the motor. Therefore, this motor rotates in the opposite direction at a low speed, and the speed is controlled according to the opening degree of the pressure reducing valve. The latter effect is determined depending on the pressure reduction state of the manually operated proportional action pressure reducing valve.

、その説明を省略する。For example, when the valve 5 is depressurized, the valve 2 opens further until it reaches the pressurizing force in the duct 3, and thus the pressurizing force acts on the motor 1. As a result, the motor 1, for example,
Perform a right rotation. On the other hand, when the valve 6 is depressurized, the pressure in the duct 4 increases, and the reverse pressure on the motor 1 also increases. By balancing the two pressures on opposite sides of the motor 1 to the appropriate IE, the speed of the motor 1 in one direction or the other is controlled. In this way, the motor 1 can be caused to wind up the rope at full speed or at low speed. Preferably, the answer valves 5 and 6 are simultaneously depressurized or opened via the mechanical lever 7. The pneumatic control circuit for braking the motor 1 shown in FIG. 1 is well known, and its explanation will be omitted.

圧状態に応じて迅速に幾分か低下する。Assuming that the port on the left hand side of motor 1 in Fig. 2 is performing a load lifting operation, the low pressure in the supply duct on the left hand side will reverse the direction or rotation of motor 1 under the applied load. It will be done. In this way, the damping counterpressure intended in the invention is obtained, and the load is quickly reduced somewhat in response to the reduced pressure state of the manually operated valve 5.
