Many common problems in the accessories of electric cranes can be solved by repairing them, so that the accessories can continue to be used. Here are some common repairable accessories and their related issues:

1. Electrical system accessories

common problem:

Motor malfunction: The motor may experience overheating, abnormal noise, and a decrease in speed, usually due to damage to the motor winding, bearing wear, or poor lubrication.

Contactors and relays malfunction: These components may cause control failure due to aging, short circuits, or poor contact.

Power line issues: Power lines may experience short circuits, open circuits, and other problems due to aging, wear, or insulation layer damage.

Repair measures:

Motor problems can generally be solved by replacing windings, bearings, or re lubricating.

Faults in components such as contactors and relays can be repaired by replacing damaged parts or cleaning and adjusting them.

If there is a problem with the power supply line, it is necessary to check and replace the damaged line section, or rewire it to ensure safety.

2. Transmission system accessories

common problem:

Gearbox malfunction: The gearbox may experience issues such as oil leakage, abnormal noise, and gear wear, which can affect transmission efficiency.

Brake malfunction: The brake may not function properly due to worn brake pads, spring failure, or improper adjustment.

Coupling and transmission shaft failure: These components may cause transmission failure due to wear, breakage, or looseness.

Repair measures:

The problem with the reducer can be solved by replacing seals, repairing or replacing worn gears, adjusting clearances, and other methods.

If the brake fails, it is necessary to replace the worn brake pads, adjust the spring force, or readjust the brake clearance.

The failure of components such as couplings and transmission shafts may require replacement of damaged parts or repair work such as welding and reinforcement.

3. Steel wire rope and pulley system

common problem:

Wear and breakage of steel wire rope: Long term use can cause wear and breakage of steel wire rope, reducing its load-bearing capacity.

Pulley system malfunction: The pulley may not rotate flexibly due to wear, jamming, or bearing damage.

Repair measures:

When the steel wire rope is worn or broken to a certain extent, it needs to be replaced with a new one.

The failure of the pulley system can be repaired by replacing worn pulleys, cleaning bearings, and re lubricating.

4. Control system accessories

common problem:

Controller failure: The controller may malfunction due to program errors, component aging, or external interference.

Limit switch and safety switch malfunction: These switches may lose their protective function due to poor contact, damage, or improper adjustment.

Repair measures:

Controller malfunction may require reprogramming, replacement of damaged components, or overall replacement.

Faults such as limit switches and safety switches can be repaired by replacing damaged switches, adjusting positions, or rewiring.
