The cable crane

The cable crane

  1. When crane uses suspension cable car (or cable guide trolley), the cable shall be protected from wear and excessive bending during movement, For cables outer diameter is not greater than 8mm, 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 flat cable, the thickness of the cable is equivalent to the diameter of the round cable.

Gantry crane cable arrangement shall ensure that each cable length is equal, Clamp pressure welding, the same layer cable diameter, as close as possible to avoid a root or a handful of cable force too much. The suspension cable trolley shall be provided with a traction steel wire rope between each other, and when running, when the adjacent two suspension cable trolley spacing makes the angle between the suspension cables close to 120 degrees, the traction steel wire rope should be fully stretched and forced.

Gantry crane

  1. When the power is supplied by cable drum should prevent cable is in the process of sports wear, The outer diameter is not more than 21.5 mm cable, cable drum bottom diameter should be at least 10 times of cable diameter.

Overhead crane cable reel should be able to automatically collect wind cable, The cable drum drive torque should not be less than the largest necessary wrapped cable winding torque. In the process of cable, the effect on the cable conductor of traction should be small as possible. For no strengthening core cable, effect on copper wire section of maximum allowable tension for 20N/mm2, When the cable winding speed is high or the cable weight is heavier, should  be add a reinforced wire rope than can bear the required traction as a core.
