Gantry crane on the cable What are the requirements?

1,  gantry crane  used suspension cable car (or cable guide car), should prevent the cable being worn during exercise and excessive bending occurs for no more than 8mm diameter cable, its cable hanging plate bending curvature diameter should be at least 6.3 times the cable diameter; 8mm diameter greater than the cable diameter should be at least 8 times; 12.5mm diameter greater than the cable should be at least 10 times the diameter; the flat cable, to the thickness of the cable on round cable diameter.

Gantry  hoist crane  cable arrangement should ensure equal length of each cable, crimp clamp securely on the same floor as close to the cable diameter, to avoid a one or a few excessive force several cables. Suspension shall be provided between the cable car traction rope, run-time, when the distance between two adjacent suspension cable car hanging cable makes an angle close to 120 ° between the traction wire rope should be completely straightened force.

2, the use of powered cable reels should be to prevent the cable being worn during exercise, for not more than 21.5mm diameter cable, cable reel bottom diameter should be at least 10 times the cable diameter; For cable diameter greater than 21.5mm , cable reel bottom diameter should be at least 12.5 times the cable diameter.

Gantry  eot crane  cable drum should be able to automatically collect wrapped cable, cable reel drive torque shall not be less than the closing wrapped around the cable wound required maximum torque. Put the cable in the process, the role of traction on the cable wires should be as small as possible, for no reinforced core cables, copper wire section on the role of the maximum permissible pulling force 20N/mm2, that require high-speed cable or cable wound weight heavier, should be able to withstand the required additional traction rope for core strengthening.
