Bridge crane is a kind of lifting equipment widely used in industrial and construction fields. The following will provide the corresponding solutions and precautions according to the common faults of bridge crane.




Crane fails to start
Solution:
1) Check whether the power supply is normal and whether there is electricity;
2) Check whether the cable is in good contact;
3) Check whether the controller is normal and has faults;
4) Check whether the motor is normal and whether there is a fault.

Precautions: Pay attention to safety when checking the power supply and cable to avoid electric shock.

The crane cannot operate normally after starting
Solution:
1) Check whether the motor is normal and whether there is a fault;
2) Check whether the transmission system is normal and whether there is a fault;
3) Check whether the controller is normal or faulty.
Precautions: When checking the motor and transmission system, attention should be paid to safety to avoid being clipped or collision accidents.

Abnormal sound occurs when the crane is running
Solution:
1) Check whether the transmission system is normal and whether there is a fault;
2) Check whether the wheel set is normal and whether there is a fault;
3) Check whether the crane structure is loose.
Precautions: When checking the transmission system and wheel set, attention should be paid to safety to avoid being clipped or collision accidents.

The crane wobbles during operation
Solution:
1) Check whether the transmission system is normal and whether there is a fault;
2) Check whether the wheel set is normal and whether there is a fault;
3) Check whether the crane structure is loose.
Precautions: When checking the transmission system and wheel set, attention should be paid to safety to avoid being clipped or collision accidents.

The crane was running at a standstill
Solution:
1) Check whether the power supply is normal and whether there is electricity;
2) Check whether the cable is in good contact;
3) Check whether the controller is normal and has faults;
4) Check whether the transmission system is normal and whether there is a fault.
Precautions: Pay attention to safety when checking the power supply and cable to avoid electric shock.




Loose CAM pieces: Loose CAM pieces can be caused by worn or damaged CAM pieces.
Solution: Replace or repair the CAM piece.
Plastic breakage at the contact roller of the linkage table: plastic breakage may be caused by aging of plastics or insufficient strength of plastics.
Solution: Replace the plastic or strengthen it.
Excessive wear at the latch of the contact roller leads to the lock after the handle returns to zero: Excessive wear at the latch of the contact roller may be caused by the wear or damage of the latch.
Solution: Replace the bolt or repair the bolt.
Stuck handle: A stuck handle may be caused by a mechanical mechanism stuck inside the handle.
Solution: Clean the mechanical structure inside the handle or replace the handle.
Wheel gnawing and cart unequal height: Wheel gnawing and cart unequal height may be due to wear or damage to the wheel.
Solution: Replace the wheel or repair the wheel.
Skid: Skid can be caused by a faulty motor or brake.
Solution: Check whether the motor and brake are faulty, if so, timely replacement or repair.

The above are some common bridge crane failures and solutions. If you are having problems with the bridge crane, you can refer to these solutions. At the same time, we also suggest that you check the equipment for obstacles, deformation, wear and other problems before use to ensure the normal operation of the equipment.
