Cable drum is a cable winding device that provides power supply, control power or control signal for large mobile devices. It is widely used in the port gate crane, container crane, loading machine, tower crane, etc.

The main products of cable drum are in the following forms: weight, torque, hysteresis and frequency conversion.

Cable drum is divided into: spring-driven cable drum and motor driven cable drum.

Spring-driven cable drum is used to control the rolling and releasing of cables, which are mainly used for cranes, stacking devices or waste water treatment technology.

The coil springs are more reliable and cheaper and can be replaced with electric ones. In particular, there is no internal power supply for mobile devices.

The flange of the spring driving drum is made of galvanized metal plate, and the outer edge of the flange is curving. The core of the scroll is made of metal sheet metal, and the outer coating is protected by polyester coating, which can be very good to prevent corrosion.
