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.
