The following is a comprehensive guide to the maintenance of XCMG truck cranes, designed to ensure the normal operation of the crane and extend its service life.
1. Daily inspection and maintenance
General examination:
Check whether the connections and fixed seals of each pipeline are loose or leaking.
Check whether the fasteners are loose, especially the fasteners between the crossbeam and chassis beam, slewing bearing, crossbeam and column.
Check whether the control switch and pressure gauge of the power output device are normal.
Check whether the hydraulic oil and lubricating oil are sufficient, ensure that the oil is clean and free of corrosive agents and unclean oil.
Check the condition of the wire rope and accessories, including whether the rope clamp is firm, whether the wire rope is in the groove, and whether there is any twisting, wrinkling, wear, rust or breakage.
Special inspection:
Check the crane components for surface damage or deformation.
Check the synchronous wire rope that drives the boom to extend and retract to ensure that it is not loose.
Put the crane in working condition and check whether the sound and temperature of the hydraulic system are normal.
Check the working condition of lighting, signals and various indicator lights and instruments.
Check the operation of the handbrake and footbrake.
2. Regular maintenance
Oil replacement:
Replace the hydraulic oil regularly. It is recommended to replace it every 2000 hours or according to the manufacturer’s recommended cycle, and use high-quality hydraulic oil.
Check and replace the gear oil, and select the appropriate gear oil according to the ambient temperature and seasonal changes.
Lubrication maintenance:
Lubricate each lubrication point regularly, including the slewing mechanism, large and small gear pairs, slewing rolling bearings, etc.
Check the lubrication condition of the hoisting mechanism drum bearings and the bearings at both ends of the traction mechanism drum, and add grease if necessary.
Cleaning and adjustment:
Clean valves and oil pumps regularly to remove attached dust and dirt and avoid blockage.
Check and adjust the brakes, safety devices and limiters to ensure they are sensitive and reliable.
Tighten the bolts or nuts at each connecting bolt, wire rope pressure plate and rope clamp, and replace them if necessary.
3. Special maintenance
Hydraulic system maintenance:
When a hydraulic system fails, a comprehensive inspection should be carried out to determine the cause of the failure and take appropriate measures to repair it.
Scan and inspect the hydraulic system regularly to ensure that valves and pipes are not loose and are properly sealed.
Electrical system maintenance:
Check the working condition of the electrical system, including whether the signal lights, wipers, etc. are working properly.
Check the electrolyte density, voltage and terminal fixation of the battery, and apply grease for protection.
Long-term inactivity protection:
When the crane is out of use for a long time, the moving parts should be lubricated and protected, and all valves should be kept in the closed state.
Carry out rust-proof treatment on hydraulic pipelines to avoid corrosion and damage.
