Truck-mounted crane is a commonly used lifting equipment, but it is inevitable that some failures will occur during long-term use. The following are common faults and maintenance solutions for truck-mounted cranes:
1. The lifting capacity is reduced or unable to lift:
This may be caused by insufficient hydraulic oil, poor oil quality, blocked oil circuits, damaged oil pumps, etc. At this time, it is necessary to check whether the hydraulic oil is sufficient, whether the oil circuit is smooth, whether the oil quality meets the standards, and the damaged oil pump should be replaced in time.
2. Electrical failure:
Electrical failures of truck-mounted cranes are usually caused by poor circuit contact, short circuit or damage to wires, damaged switches, etc.It is necessary to check whether the circuits, wires and switches are normal and replace damaged parts in time
3. The oil pump makes loud noise or leaks oil:
This may be due to reasons such as worn oil pump bearings, poor sealing, or damaged oil seals. It is necessary to check whether the oil pump bearings are worn and whether the seals are in good condition, and replace damaged oil seals in time.
4. Poor balance of truck mounted crane:
Poor balance of the truck-mounted crane is usually caused by unstable vehicle chassis structure, aging wire rope, wear of pulleys, etc. It is necessary to check whether the vehicle chassis structure is stable, whether the wire rope is aging, whether the pulleys are worn, and damaged parts should be replaced in time.
5. Operating mechanism failure:
Failure of the truck-mounted crane operating mechanism is usually caused by deformation of the connecting rod, damage to the spring, wear of the connecting rod bearing, etc. It is necessary to check whether the connecting rod, spring and connecting rod bearing are normal, and replace damaged parts in time.
Repairing a truck-mounted crane requires professional skills and experience, so it is recommended to seek professional maintenance services or contact the truck-mounted crane manufacturer for repairs. At the same time, regular maintenance of truck-mounted cranes is also very important, which can extend the service life of the equipment and improve safety performance.
