What should be paid attention to in the routine inspection and maintenance of wire rope electric hoist reel？
As an important component of electric hoist, the reel is squeezed, flexed and torsional during the working process. An accident usually caused by a reel, most of the extruding and torsional stations. Therefore, in the routine maintenance process, such as the discovery of a crackle in the drum, it should be discarded immediately to eliminate the hidden danger of safety. Next, the wear degree of the rope grooves shall not exceed 2 millimeters. If it is over, the grooves must be rebuilt, but the wall thickness of the reel shall not be less than 80% of the original wall thickness, and there shall be no cracks on the top and bottom of the drum.
In the routine inspection and maintenance of drum, if it is found that the wire rope deviates on the drum, when the angle between the wire and the slot is too large, the steel wire will easily accelerate the wear of the rope slot or even job hopping, which will cause serious wear of the wire rope.
The common reason is that the hook pulley group is too small from the drum and can be adjusted properly. It may also be due to the skew of the safety position of the hook pulley group and the reel, or the skew of the skew cargo to make the wire rope jump. In addition, the replacement of wire rope, wire rope winding if twisting (due to winding in the wood roll) did not relax, also can make the wire rope quit, or even make a few rope pulleys in, in order to prevent the accident, can be put into the rope disc hanging up gradually open straight, twisting can be completely disappeared.
