The electric chain hoist is a type of light and small lifting equipment and is widely used in production process upgrades and work efficiency improvements. However, during use, some faults may occur. Below we will introduce some common faults and repair methods.
1. Broken chain or wire rope
Chain or wire rope breakage is one of the common faults of electric chain hoists. When a chain or wire rope breaks, use should be stopped immediately to avoid greater damage. Before repair, it is necessary to check the reasons for the breakage of the chain or wire rope, such as overloading, poor operating environment, aging equipment, etc. Replace the chain or wire rope with a new one and install and adjust it correctly.
2. Motor failure
Motor faults of electric chain hoists include motor overheating, motor failure to start, etc. When the motor overheats, it may be caused by overloading or poor heat dissipation of the motor. The load needs to be checked and the motor must be properly cooled. When the motor fails to start, it may be caused by a power failure or motor failure. Check whether the power supply is normal, and inspect and repair the motor.
3. Control failure
Control failures of electric chain hoists include inability to rise and fall, etc. When a control failure occurs, it may be caused by a fault in the control circuit or damage to the controller. Check whether the control circuit is well connected, and inspect and repair the controller.
4. Brake failure
Brake failures of electric chain hoists include insensitive brakes, non-working brakes, etc. When the brakes fail, it may be caused by a faulty brake mechanism or worn brake pads. It is necessary to check whether the brake mechanism is working properly and replace worn brake pads.
5. Oil leakage
Oil leakage from the electric chain hoist will affect the normal operation and service life of the equipment. Oil leakage may be caused by aging oil seals or damaged gaskets. The oil seal or gasket needs to be replaced and other components checked for oil leakage.
To sum up, common faults of electric chain hoists include chain or wire rope breakage, motor failure, control failure, brake failure and oil leakage. For different faults, corresponding maintenance measures need to be taken to repair them. Regular inspection and maintenance of equipment can reduce the occurrence of failures and improve the service life and safety of equipment.
