Cable Drum

Cable drum operation principle

    Long-timely hindered rotation type which the power part of cable drum and regulating speed part beared by motor with uniqueness electrical and mechanical, which has a wide of speed adjustment and softer mechanical characteristics. The corresponding change of the rotational speed of the motor happens when changing in load, namely load increases the rotational speed to drop, load drops the rotational speed raises. It features all long and steady operation at whatever of their torque and rotational speed of mechanical curves.  So can guarantee the cable obtain proper coiling speed and pulling force on the corresponding radius.

1. Coiling up: Cable motor outputs torque as power force, coiling up cable by reductor running the spool to coil up cable.

2. Release cable: Motor leaves strength of hindering from torque, preventing the cable from drawing spool fast, it guarantees putting synchronous of releasing cable.

3. When machinery shutting down, long- timely motor have plate type often close brake, which can guarantee the cable will not back fall from a plate for the action of the gravity  when  power cutting off.
