No matter what mechanical equipment, various failures will occur during daily use. If there is a failure, it should be maintained in time. Of course, when maintaining, you should master the precautions for maintenance of the electric hoist. In order to prevent accidents, let me introduce to you several situations where the electric hoist wire rope breaks.
Normal wire rope break
There is no way to prevent normal wire breakage. Wire rope is a vulnerable part, and wire breakage occurs only after several years of use. Because the wire rope of the electric hoist needs to pass through the pulley rope groove and drum continuously during use, it is subject to squeezing, friction, torsion and other effects. After a long time, it is easy to cause fatigue and wire breakage. In addition, other factors such as wear and rust will cause The situation of broken wire in the wire rope is corrected.
The wire rope is broken during the topping
After the topping, the rope guide is broken, causing the rope to wind randomly, turning out of the drum area, and hinged to the motor and gear box, causing the wire rope to break. Broken wire can be completely prevented. In addition to the stock-out limiter, our electric hoist also adds a heavy hammer limiter, which will effectively avoid the occurrence of topping.
The wire rope is broken by overload
This situation is caused by the operator's miscalculation of the weight of the lifting object, which causes the weight to exceed the rated lifting capacity. The probability of this situation is very small. It can be avoided as long as the operator carefully estimates before lifting!
To prevent the wire rope from breaking, the maintenance work should be done well. It is recommended to check the appearance of the wire rope every week. For the wire rope with more severe wire break, it should be replaced in time. When the hoist wire rope needs to be replaced, its winding must be carried out by professional staff to ensure accurate winding. The daily inspection of the electric hoist is very important, not only can effectively prevent the wire rope from breaking and the loss of other accessories, but also can extend the service life of the entire electric hoist.
