High bending drum cables are widely used in the connection and control of heavy machinery equipment such as construction vertical elevators, port gantry cranes, container cranes, loading/unloading ships, large gantry cranes, tower cranes, etc. Flexible cables are suitable for situations with high mechanical stress, especially tensile and torsional stress. Drum cables can meet various electrical installations in dry or humid indoor industrial environments, and can also be used for installation in harsh outdoor environments.
High bending drum cablefeature
▲ Soft, resistant to bending and twisting, with excellent performance
▲ Tensile and tear resistance, stable performance
▲ Has good oil resistance, shallow water resistance, wear resistance, weather resistance, and UV resistance
The flat cable reel can be bundled with multiple cables, effectively saving installation space for the cables.
Huangma rope is added between the cable cores to carry the load, and a layer of non-woven fabric buffer is wrapped between the core wire and the sheath. In the case of ultra-high length, galvanized steel wire rope, imported aramid yarn, and tensile flagpole rope are also available for selection, which have good tensile and tear resistance while maintaining flexibility.

High bending drum cablePrecautions
1.When installing the electric motor, it is necessary to ensure that the direction of rotation of the electric motor, the direction of rotation of the one-way bearing, and the direction of rotation of the drum cable are consistent. When multiple drives are used, it is necessary to ensure that the direction of rotation of multiple electric motors is consistent. Therefore, a separate jog test should be conducted before installing the electric motor. ...
2.The drum drive motor must start synchronously with the main engine's walking mechanism, and when the main engine stops, the cable drum must be delayed and powered off.
3.The adjustment of torque should be appropriate, too large can increase the load on the drum structure and cable, while too small can cause the cable to loosen. When multiple drives are used, efforts should be made to balance the winding torque of each drive as much as possible.
4.The adjustment of torque should be done using specialized tools and gradually, with each adjustment of the shaft sleeve rotation angle not exceeding -. When adjusting, do not exceed its adjustment range, otherwise it may damage the hysteresis coupling.
