EN Polipastos eléctricos de cadena, as a light and small lifting equipment, 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 polipastos eléctricos de cadena 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.
If the motor of the electric chain hoist 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.
Main reasons for the heating of the electric chain hoist motor:
- The electric chain hoist is overloaded, which causes the motor to drive too much power, which causes the motor to overheat.
- The voltage of the electric chain hoist is too high, causing the motor to overheat.
- Construction in a high temperature environment, such as high ultraviolet rays in summer, and the problem of overheating of the motor caused by overheating.
- 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.
How to solve the problem of motor heating?
- Check whether it is because the electric hoist weight is too large, Overweight operation will make the motor over heating, overload for a long time will cause irreparable damage to the electric chain hoists for sale.
- Electric hoist motor is not overloaded, but still heating, should check whether the motor bearing damaged; Should also check whether the motor work according to regulations.
- When the electric hoist motor is running, brake clearance is too small, not completely disengaged, causing great friction, while the frictional heating is also equivalent to the additional load, the motor speed is reduced, then we should let the electric hoist cooling.
- Adjust the brake clearance before running the electric chain hoist again. The use of electric hoist must always pay attention to the abnormal response of electric chain hoists for sale, in order to avoid accident.
