The hysteresis cable reel is transmits the power supply for the large-scale mobile hoisting equipment between two relative vehicles, the control supply or the control signal coiling installment. It widely applies in the harbor gate place hoist crane, the container hoist crane, the ship loader, the tower crane and so on similar operating mode heavy duty machinery equipment. The hysteresis cable reel is in the present cable winder the ideal coiling equipment, it with the commonly used counterweight type, the moment of force electrical machinery type cable drum compares, has the volume to be young, function entire, the installment service is convenient, the approximate permanent tensity, may act according to the actual operating mode request adjustment output torque, and has good from the brake function, does not need to install the brake, the cable drum movement is reliable, can stop up for a long time transfers, but does not damage. cable reel drum transmits the power for large-scale mobile hoisting equipment between two relative vehicles, control power supply or control signal coiling installment. It is widely used in the harbor gate place hoist crane, the container hoist crane, the ship loader, the tower crane and some similar operating mode heavy duty machinery equipment. The magnetic motor type cable drum is in the present cable winder the ideal coiling equipment, it with the commonly used counterweight type, the moment of force electrical machinery type cable drum compares, has the small CBM, function entire, the installment service is convenient, the approximate permanent tensity, may act according to the actual operating mode request adjustment output torque, and has good from the brake function, does not need to install the brake, the cable drum movement is reliable, can stop up for a long time transfers, but does not damage.
