As a light and small lifting equipment, electric chain hoist is widely used in various industries in docks, factories, warehouses, construction and assembly line production operations. Its main components are electric motors, transmission mechanisms and sprocket, each component The functions of the electric chain hoist are different. With long-term use, the service life of each component will be shortened due to load, friction and other reasons. If the scrapping standard is not checked and repaired in time, the electric chain hoist will be damaged and the work will be delayed. The progress even threatens the user's life and health.

The motor of the electric chain hoist is the same as a human, and the motor itself will be "tired". If the motor continues to heat up, there is a risk of burnout. Just like a person with a high fever, a continuous high fever will burn the brain, and the motor will burn the internal parts.

There are several reasons for the heating of the electric chain hoist motor:

  1. The electric chain hoist is overloaded, which causes the motor to drive too much power, which causes the motor to overheat.
  2. The voltage of the electric chain hoist is too high, causing the motor to overheat.
  3. Construction in a high temperature environment, such as high ultraviolet rays in summer, and the problem of overheating of the motor caused by overheating.
  4. The electric chain hoist has been used for too long, and the motor has been generating electricity for too long, which may cause the motor to overheat.

When the electric chain hoist is used, the motor is overheated. At this time, stop the operation and continue the operation after the temperature of the motor returns to normal. According to the cause of heat generation, correctly handle the heat generation failure. Do not work in a diseased state of the electric chain hoist to prevent the motor from burning out. If the motor burns out, it is equivalent to the electric hoist being in a scrapped state.
