The selection requirements of Bridge Crane Cable

 Bridge Crane Cable

When the Overhead crane adopts a suspension cable car (or cable guide), Should prevent the cable in sports wear and excessive bending, For cables with an outer diameter of not more than 8 mm, the curvature diameter of the cable suspension bending plate shall 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; At least 10 times the outer diameter of a cable with a diameter greater than 12.5mm. For flat cables, the thickness of the cable is equal to the diameter of the circular cable.

The length of cable should be equal when the cable of gantry crane is arranged. Press the plate firmly, the outer diameter of the same layer cable as close as possible, to avoid one or a few cable excessive force. Traction Wire Rope should be arranged between the suspended Cable trolley and each other. In operation, when the distance between two adjacent suspension cable trolleys makes the angle between the suspended cables close to 120 °, the traction wire rope should be completely straightened.

When using cable reel to supply power, it is necessary to prevent the cable from being worn out in the course of motion. For cables with an outer diameter of not more than 21.5 mm, the bottom diameter of the reel of the cable shall be at least 10 times the outer diameter of the cable. For cables with outer diameter greater than 21.5 mm, the bottom diameter of the cable reel should be at least 12.5 times the outer diameter of the cable.

The cable reel of the bridge crane shall be able to unwind the cable automatically, and the driving torque of the cable reel shall not be less than the maximum winding torque required for the winding of the cable. During cable release, the traction acting on the cable conductor should be as small as possible. For cables without reinforced cores, the maximum allowable pull on the copper conductor section is 20 N / mm 2, When the winding speed of cable is high or the weight of cable is heavy, the reinforced wire rope which can withstand the needed traction should be added as core.
