Forklifts are industrial handling vehicles, which refer to various wheeled handling vehicles for loading and unloading, stacking and short-distance transportation of palletized goods. The following is a sharing of maintenance methods for internal combustion forklifts and battery forklifts, hoping to help everyone!
Secondary technical maintenance of internal combustion forklifts and battery forklifts
1. Clean each oil tank, filter screen and pipeline, and check for corrosion and cracking. After cleaning, do not wipe with yarn heads or cloth with fibers.
2. Clean the torque converter and gearbox, check the wear of parts, and replace new oil.
Check the drive shaft bearings and change the direction of the universal joint cross shaft as needed.
3. Check the tightness of each part of the drive axle and whether there is oil leakage, and dredge the air holes. Disassemble and inspect the main reducer, differential, and wheel reducer
4. Adjust the axial clearance of the bearing and add or replace the lubricating oil.
5. Disassemble, adjust and lubricate the front and rear wheel hubs, and perform half-axle transposition.
6. Clean the brakes and adjust the gap between the brake drum and the brake shoe friction plate.
7. Clean the steering gear and check the free rotation of the steering wheel.
8. Disassemble and clean the gear oil pump, and pay attention to the wear of the gears, housing and bearings.
9. Disassemble the multi-way valve and check the gap between the valve stem and the valve body. Do not disassemble the safety valve if it is not necessary.
10. Check whether the steering knuckle is damaged or cracked, the matching of the steering axle kingpin and the steering knuckle, and disassemble and inspect the wear of the longitudinal and transverse tie rods and steering arm joints.
11. Disassemble the tires, remove the rust and paint the rims, check the inner and outer tires and cushions, replace them and inflate them according to regulations.
12. Check the connection and tightness of the hand brake parts, and adjust the working stroke of the hand brake lever and foot brake pedal.
13. Check the battery forklifts battery liquid specific gravity. If it does not meet the requirements, it must be removed and charged.
14. Clean the water tank and oil radiator.
15. Check whether the shelves and frames are deformed, remove and clean the rollers, and check whether the accessories are securely fixed. If necessary, tighten them.
16. Disassemble and inspect the lifting cylinder, tilt cylinder and steering cylinder, and replace worn seals.
17. Check the sensors, fuses and switches of various instruments, and adjust them if necessary.
