Overhead crane cable 

What is the requirements to overhead crane cable?

The use of suspension crane cable car (or crane cable guide), should prevent the crane cable in the movement was worn and over bending.

For crane cable diameter greater than 8mm, the crane cable hanging curved plate diameter should be at least the crane cable diameter For the outer diameter of more than 8mm of the crane cable, at least 8 times the outer diameter; for the diameter of more than 12.5mm crane cable, at least 10 times the outer diameter; for flat crane cable, the crane cable thickness is equivalent to the diameter of the round crane cable.

Crane cable arrangement should ensure that the crane cable length is equal, the pressure plate crimp firmly, the same layer of crane cable diameter as close as possible to avoid a root or a few crane cables too much force. Suspension crane cable trolley should be set between each other to pull the wire rope, the operation, when the adjacent two hanging crane cable trolley spacing between the crane cable so that the angle between the 120 °, the traction wire rope should be completely straightened force.

The use of crane cable reel power supply should be prevented during the movement of the crane cable was worn, the diameter of not more than 21.5mm crane cable, crane cable drum diameter should be at least 10 times the crane cable diameter; for the diameter of more than 21.5mm crane cable, The crane cable drum diameter should be at least 12.5 times the crane cable diameter.
The crane cable reel shall be capable of automatically winding the crane cable. The drive torque of the crane cable reel shall be not less than the maximum winding torque required for the winding crane cable. In the process of crane cable laying, the traction force acting on the crane cable conductor should be as small as possible. For crane cables with no reinforcement core, the maximum allowable tension on the copper conductor cross section is 20N / mm2. For crane cable winding speed or crane cable weight Heavier, should be added to withstand the required traction to strengthen the wire rope for the core.
