common faults of XCMG truck mounted crane and how to deal with them

 

How to solve the problem of reduced lifting capacity of truck crane?

Some common problems may arise during use of XCMG car cranes. The following are some common problems and how to deal with them:
1. Hydraulic system problems
• Problem manifestations: oil leakage, slow movement or weakness in the hydraulic system.
• Processing method:
• Check whether the hydraulic oil is sufficient and whether the oil is deteriorated. If necessary, replace the hydraulic oil.
• Check whether the connection parts of the hydraulic system are loose or damaged, and tighten or replace the seals in time.
• Check whether the hydraulic pump, hydraulic cylinder and other components work normally. If there is a fault, it needs to be repaired or replaced in time.
2. Problems of boom telescopic
• Problem manifestation: The boom is not telescopic or shakes when telescopic.
• Processing method:
• Check the lubrication of the telescopic arm to ensure good lubrication.
• Check the sliders and slides of the telescopic arm for wear or debris, clean up debris and repair the worn areas.
• Check whether the hydraulic system is normal, especially the telescopic cylinder and control valve, and repair or replace if necessary.
3. Engine problems
• Problem manifestations: Difficulty starting the engine, insufficient power or excessive fuel consumption.
• Processing method:
• Check the fuel system, including fuel filters, fuel pumps, etc., to ensure normal fuel supply.
• Check the engine intake system, including air filters and intake lines, to ensure that the intake is unobstructed.
• Check the engine fuel injector, high-pressure oil pump and other components, and clean or replace it if necessary.
4. Braking system issues
• Problem manifestation: The braking effect is poor or the vehicle runs off during braking.
• Processing method:
• Check whether the brake system is leaking, especially the brake lines and brake cylinders.
• Check the wear of the brake shoe and replace the brake shoe if necessary.
• Adjust the brake clearance to ensure the brake system is working properly.
5. Electrical system problems
• Problem manifestation: The electrical equipment does not work properly or the lights are not on.
• Processing method:
• Check whether the electrical circuits are short circuit, broken circuit or poor contact.
• Check whether the generator and battery are working properly, and charge or replace if necessary.
• Check whether the fuse of the electrical equipment is blown and replace it in time.
6. Operational safety issues
• Problem manifestation: There is a risk of overturning or an overload alarm during operation.
• Processing method:
• Operate strictly in accordance with operating procedures to ensure that the crane works on a flat and solid ground.
• Check that the crane’s legs are secure before operation to ensure that the legs are fully unfolded and locked.
• Strictly adhere to the crane’s load rating table to avoid overload operations.
