1. When the electric bridge crane adopts the hanging cable trolley, the cable should be prevented from being worn and excessively bent during the movement. For cables with an outer diameter of not more than 8 mm, the diameter of the cable suspension curved plate should be at least 6.3 times the outer diameter of the cable. For cables with an outer diameter greater than 8 mm, at least 8 times the outer diameter; for cables with an outer diameter greater than 12.5 mm, at least 10 times the outer diameter; for flat cables, the thickness of the cable is equivalent to the diameter of the round cable.
2. When the electric bridge crane adopts cable reel for power supply, the cable should be prevented from being worn during the movement. For cables with an outer diameter of not more than 21.5mm, the cable reel bottom diameter should be at least 10 times the outer diameter of the cable; for cables with an outer diameter greater than 21.5mm The bottom diameter of the cable drum should be at least 12.5 times the outer diameter of the cable.
3. When the cable of electric bridge crane is arranged, ensure that the length of each cable is equal, the pressure plate is firmly crimped, and the outer diameter of the same layer of cable is as close as possible, to avoid excessive stress on a certain cable or a few cables.
