Use and maintenance of electric forklifts

Second, the first-level technical maintenance is carried out in accordance with the " routine maintenance" project, and the following work is added. 1. Check cylinder pressure or vacuum. 2. Check and adjust the valve clearance. 3. Check if the thermostat works normally. 4. Check whether the multi-way reversing valve, lift cylinder, tilt cylinder, steering cylinder and gear pump work normally. 5. Check if the shifting work of the transmission is normal. 6. Check and adjust the gap between the brake pads of the hand and foot brakes and the brake drum. 7. Replace the oil in the oil pan, check whether the crankcase ventilation pipe is intact, and clean the oil filter and diesel filter.

8. Check whether the generator and starter motor are installed firmly, and whether the wiring head is clean and firm, check the carbon brush and commutator for wear. 9. Check the tightness of the fan belt. 10. Check that the wheel is installed securely, whether the tire pressure meets the requirements, and remove the debris embedded in the tread. 11. Disassemble the parts due to maintenance work, and carry out the forklift road test after reassembly. (1) Braking performance under different degrees should be no deviation, meandering. On the steep slope, the hand brake can be stopped after being tightened. (2) Listening to the engine running under acceleration, deceleration, heavy load or no-load, etc., with or without abnormal sound. (3) After a mileage test, check the brakes, transmission, front axle housing, and gear pump for overheating. (4) Whether the fork lift speed is normal and there is no tremor. 12. Check the diesel tank oil inlet filter for blockage and damage, and clean or replace the filter.

Third, secondary technical maintenance In addition to the first-level technical maintenance of the various items, and add the following work: 1, cleaning the fuel tank, filter and pipeline, and check for corrosion, cracking, after the cleaning should not be used with fiber The yarn ends are rubbed with cloth. 2. Clean the torque converter, gearbox, check the wear of the parts, and replace the new oil. 3. Check the drive shaft bearing and change the direction of the universal joint cross shaft as needed. 4. Check the fastening condition of each part of the drive axle and whether there is oil leakage or ventilating. Remove the main reducer, differential, and wheel reducer, adjust the axial clearance of the bearing, and add or replace the lubricant. 5. Dismantle, adjust and lubricate the front and rear hubs for half shaft reversal. 6. Clean the brake 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, pay attention to check the wear of the gear, housing and bearing. 9. Disassemble the multi-way valve, check the clearance between the valve stem and the valve body. If not, do not disassemble the safety valve. 10. Check the steering knuckle for damage and cracks, the cooperation between the main pin of the steering axle and the steering knuckle, and disassemble the wear of the joints of the vertical and horizontal tie rods and the steering arm. 11. Remove the tires, remove the rust and paint the rim, inspect the inner and outer tires and the belt, change the position and inflate according to the regulations. 12. Check the connection and fastening of the hand brake mechanism and adjust the working stroke of the hand brake lever and the foot brake pedal. 13. Check the battery electro-hydraulic specific gravity. If it does not match the requirements, the charging must be removed. 14. Clean the water tank and oil radiator. 15. Check the shelf, the frame for deformation, the washing and unloading roller, whether the attachments are fixed, and if necessary, add welding. 16. Disassemble the lifting cylinder, tilt the cylinder and steering cylinder, and replace the worn seals. 17. Check the instrument sensors, fuses and various switches and adjust if necessary. 4. Lubricate the new forklift truck after the whole vehicle or the forklift truck after long-term stop work. For the bearing that should be lubricated within the first two weeks of use, when refueling, the new oil should be used to extrude the whole oil and lubricate twice. Above, at the same time should pay attention to the following points: 1. Before lubricating, remove the dirt on the oil cover, oil plug and grease nipple to prevent dirt from falling into the mechanism. 2. When the lubricant is injected with a grease gun, it should be injected into the parts of each part and combined with the extrusion lubricant. 3. Seasonal lubricants (oil, etc.) should be replaced in summer or winter.
