Truck cranes have the characteristics of both construction machinery and road machinery. Due to their complexity, daily good maintenance and maintenance are required to prolong the service life of the equipment and reduce the
Low failure rate, thereby improving the reliability and economy of the equipment, so how to maintain the truck crane?
1. The hydraulic system of the truck crane should be regularly maintained and checked
The items for regular maintenance and inspection of the hydraulic system of the truck crane include: whether the hydraulic oil tank is loose and damaged; whether there are cracks and oil leakage; whether the oil quantity meets the specified requirements, and whether the hydraulic
Whether the oil is contaminated, whether the viscosity has changed: whether the hydraulic pump is loose and damaged, etc.
2. Regular maintenance and inspection of the oil pump drive device of the truck crane
Whether the operating state of the joystick is good; whether the power take-off device is loose and leaking oil; whether there is abnormal noise and heat generation: whether the drive shaft flange and connecting parts are loose; whether there is vibration
movement, scratches and abrasions.
3. Items for regular maintenance and inspection of the slewing system of truck cranes
Whether the turntable is cracked and deformed; the quantity and quality of the lubricating oil of the reducer; the reduction box body is free of cracks, deformation and oil leakage; whether the reducer and the slewing bearing have abnormal noise, vibration and oil leakage.
4. Items of regular maintenance and inspection of truck crane luffing system
Whether the oil pin of the luffing cylinder is seriously worn or damaged; whether the bolts of the pin shaft baffle are tightened, etc.
5. Items for regular maintenance and inspection of the lifting system of truck cranes
Whether the hydraulic motor is loose and cracked; whether there is oil leakage; whether the casing is deformed and cracked; whether there is noise and vibration during operation; whether the pipe joints are loose and oil leakage, etc.
6. Items for regular maintenance and inspection of the main boom retraction system of the crane
Whether the main arm has cracks, deformation and damage; whether the main arm shaft pin baffle bolts are tightened; whether there are scratches on the sliding surface; whether the fulcrum bushing is worn or damaged; whether the sliding surface is lubricated
Is it good and so on.
7. Regular maintenance and inspection of crane operation, instruments and safety devices
Whether the functions of the joystick and pedal are complete and effective, and whether there is a gap: whether the work light is normally lit, whether the installation is qualified; whether the windshield wiper can operate normally, and whether there are brushes
wear or damage, etc.
8. Regular maintenance and inspection of the crane outrigger mechanism
The natural retraction of the lifting cylinder during lifting: natural sinking during driving, whether the pipe joints are loose, whether there is oil leakage in each part, etc.
9. Items for regular maintenance and inspection of crane supports and accessories
Brackets for twists, bends and cracks; accessories for damage or loss.
10. Daily maintenance of cranes
Truck cranes should choose appropriate hydraulic oil, lubricating oil and fuel oil according to temperature changes. Hydraulic oil, lubricating oil and fuel must be kept clean. when adding
The oil filler should be wiped clean. When the filler port has a filter, do not put down the filter to refuel, etc.
