The cable used and the selection requirements of Overhead Crane Cable

The cable used and the selection requirements of Overhead Crane Cable

1. When the Overhead Crane Cable uses the suspension cable trolley(or cable guide), the cable should be prevented from being worn out and excessively bent during the movement.

2. For the outer diameter is not more than 8 mm cable, the cable diameter hanging the curvature of the curved plate should be at least 6.3 times of cable diameter; For cable diameter greater than 8 mm, should be at least eight times the outer diameter; For cable diameter greater than 12.5 mm, should be at least 10 times the outer diameter; For flat cable, the thickness of the cable is equivalent to the diameter of the round cable.

The length of each cable should be equal when the cable arrangement of Gantry  Crane Cable, The press plate is pressed firmly and the outer diameter of the same layer is as close as possible, so as to avoid over load of one or a few cables. Suspension cable trolley should be equipped with traction wire rope between each other, when running, when the adjacent two suspension cable trolley spacing makes the angle between the suspension cables close to 120 degrees, the traction steel rope should be fully straightened force.

2. When power is supplied by cable drum should prevent cable is in the process of sports wear and tear, The outer diameter is not more than 21.5 mm cable, cable drum bottom diameter should be at least 10 times of cable diameter; For cable diameter greater than 21.5 mm, the bottom of the cable drum diameter should be at least 12.5 times of cable diameter.

The cable drum of the Overhead Crane Cable should be able to automatically wrap the cable, and the driving torque of the cable drum should not be less than the maximum winding torque required when the cable is wrapped. In the process of cable, the effect on the cable conductor of traction should be small as possible, For cables without core reinforcement, the maximum allowable tensile force acting on the copper conductor section is 20N/mm2. For the cable winding speed is high or the cable deadweight is heavier, the reinforcing steel wire rope which can bear the required pull force should be added as the core.
