During the use of electric hoists, various malfunctions may occur. The following is a summary of six common faults, combined with relevant information in reference articles for point wise representation and induction:

1. Motor malfunction

Cause of malfunction:

Motor aging and component damage.

Motor overload, such as excessive carrying capacity or exceeding rated load.

Short circuit in the circuit, causing the motor to overheat or burn out.

Voltage instability affects the efficiency of motor operation.

Prevention and treatment methods:

Regularly inspect the motor for any abnormal phenomena, such as abnormal noises or odors.

Avoid motor overload and ensure operation within rated load.

Check the circuit connections to prevent short circuits from occurring.

Monitor voltage stability to ensure normal motor operation.

2. Electrical malfunction

Cause of malfunction:

Electrical components such as switches and controllers are damaged.

The power cord is broken or has poor contact.

Prevention and treatment methods:

Regularly inspect electrical components and replace damaged ones in a timely manner.

Ensure that the power cord is firmly connected without any breakage or poor contact.

3. Safety relay failure

Cause of malfunction:

Poor suction of safety relay.

Excessive contact gap or poor contact.

Prevention and treatment methods:

Regularly check the suction status and contact clearance of the safety relay.

If a malfunction is found, adjust or replace the safety relay in a timely manner.

4. Computer control system malfunction

Cause of malfunction:

The controller chip is damaged.

The driver board is necrotic.

Communication failure with the upper computer.

Prevention and treatment methods:

Regularly check the working status of the computer control system.

If a malfunction is found, replace the controller chip, driver board, or check the communication connection in a timely manner.

5. Belt and chain faults

Cause of malfunction:

Belt or chain breakage, looseness or deviation.

Prevention and treatment methods:

Regularly check the wear and tightness of belts and chains.

Timely replace broken and loose belts and chains, and adjust offset belts and chains.

6. Wear and tear fault

Cause of malfunction:

Wear and tear on components such as hooks, wheels, and rails.

Prevention and treatment methods:

Regularly inspect the wear of components such as hooks, rollers, and tracks.

Timely replace severely worn components to ensure the normal operation of the hoist.
