Electric hoist is not a piece of cloth, depression, we can not repair things, direct the repair, this time we have to think of any solution.
Electric hoist from the ground, first we have to build a maintenance platform, based on the damage of the steel wire rope and rope guide, decide whether to dismantle, if you need to replace the wire rope and wire will be all removed. Then normal pitch of the drum and the housing with a ruler to measure the L, the spool and the housing recess at the minimum spacing R, the maximum diameter of the recess is D, based on the data of the three above, select the diameter d of the high-strength member length Q, requirement is R <d <L,Q> D, high-strength components at the repair site generally choose a more convenient screw, high strength, diameter, without teeth sawing length can screw ready, screw placed in the edge of the drum and the housing depression pitch, jog electric hoist control handle button, so that the reel rotates counterclockwise, and gradually feed screw, the torque effect of the roll extrusion screw, screw oppression case depression, forcing the depression recovery to be fully restored, roll clockwise, exit screw. Finally, wire rope, hook and rope guide installed, debugging limit can be.
