The wire rope electric hoist is a widely used lifting hoist in China, mainly consisting of two common models: CD1 and MD1. When the steel wire rope electric hoist lacks certain configurations, some configurations are aging, or it is not used in a standardized manner, the phenomenon of steel wire rope electric hoist failure can occur, which can bring certain harm.

　　1、 The wire rope electric hoist has insufficient self configuration without rope guides and lifting limit configurations, resulting in the failure of height limit, which directly leads to the occurrence of top impact. There is no overload device, and overload protection fails, which can easily cause overloading and damage the basic accessories of the electric hoist.

　　2、 Part of the accessories of the electric hoist with steel wire ropes are aging, and the steel wire ropes are prone to cracks or obvious damage, which can lead to the breakage of the steel wire ropes and cause weight loss, posing a serious threat to life and property safety. The insulation damage is generally caused by the aging of cables, which may lead to leakage. Brake wear, oil stains on the brake surface, and loose brake rings can lead to excessive braking distance and exceeding the tolerance. Wheel flange wear causes excessive wheel clearance, which affects usage. Poor sealing can cause oil leakage in the reducer, and it is necessary to replace the sealing ring in a timely manner.

　　3、 Improper use can cause wiring errors, resulting in ineffective emergency stops and inability to stop in a timely manner. Wiring should be strictly carried out in accordance with the wiring instructions. In addition, situations such as excessive overloading, low voltage, and electrical failures can cause the electric hoist to fail to start. There are three main reasons for the failure of wire rope electric hoists. To reduce the occurrence rate of faults, you can consult the manufacturer before purchasing if they have the corresponding configuration, and do not take small gains and suffer big losses. In addition, after using the electric hoist for a period of time, there may be some problems with the accessories, and it is necessary to pay attention to maintenance and upkeep in daily life. If problems occur, replace the parts promptly. Furthermore, when using it, it is necessary to have professional personnel strictly follow the instructions and strictly prohibit arbitrary operation.
