When using an electric chain elevator, some common malfunctions may be encountered. Here are some common faults and their corresponding solutions:

Chain malfunction:

Fault manifestations: Chain breakage, deformation, shortening or excessive elongation, etc.

Solution: Check the wear of the chain and replace severely worn chains in a timely manner. Meanwhile, pay attention to the lubrication of the chain to maintain its flexibility and durability.

Sprocket wear:

Fault manifestation: The sprocket is severely worn, affecting the transportation effect.

Solution: Replace worn sprockets in a timely manner and lubricate new sprockets to extend their service life.

Motor malfunction:

Fault manifestation: The motor cannot function properly, which may be caused by circuit faults, internal motor faults, or voltage issues.

Solution: Check if the circuit connectors are loose, if the internal heat dissipation of the motor is poor, and if the voltage is normal. During maintenance, pay attention to whether the insulation performance of the motor meets the standard to avoid hazards such as electric shock and fire.

Bearing failure:

Fault manifestation: After the bearing is damaged, it affects the lifting performance of the elevator, leading to a slowdown in lifting speed, increased noise and vibration, etc.

Solution: Replace damaged bearings in a timely manner, pay attention to the lubrication of the bearings, and regularly replace aged lubricating oil to ensure the normal operation of the bearings.

Electrical control system malfunction:

Fault symptoms: incorrect wiring connection inside the electrical control box, blown fuse, etc.

Solution: Check the wiring connection inside the electrical control box and replace the blown fuse in a timely manner. At the same time, pay attention to the maintenance and upkeep of the electronic control system to avoid malfunctions.

Limit switch malfunction:

Fault manifestation: The limit switch is malfunctioning, causing the elevator to fail to stop after reaching its limit position.

Solution: Check and clean the limit switch, and replace the faulty limit switch in a timely manner. Ensure the reliability and effectiveness of limit switches.

Poor lifting:

Fault manifestation: The elevator lifting is not smooth, which may be caused by chain stretching, hydraulic system failure, and other reasons.

Solution: Adjust the tightness of the chain to solve the problem of chain stretching. At the same time, check the working condition of the hydraulic system, and promptly repair and replace damaged components.
