When it comes to electric forklifts
, the first thing that comes to mind is warehousing and freight. Because warehousing and logistics mainly store, stack and transport goods, then electric forklifts
must be used to save time and improve efficiency in principle. With a lot of goods and heavy tasks, the working hours of electric forklifts will become longer, and it is inevitable that some failures will occur. In order to avoid unexpected situations of forklifts during operation, electric forklift manufacturers need electric forklifts to do regular operations after running for a period of time. Not only that, but it also needs to be maintained for a long time if it is not used for a long time, so as to avoid the situation that the machine cannot run when you want to use it. 1. Level 1 technical maintenance After 100 hours of accumulated work, one shift is equivalent to 2 weeks. 1. Check and adjust the valve clearance. 2. Check whether the thermostat works normally. 3. Check whether the multi-way reversing valve, lifting cylinder, tilt cylinder, steering cylinder and gear pump work normally. 4. Check whether the shifting work of the transmission is normal. 5. Check and adjust the gap between the brake pads of the hand and foot brakes and the brake drum. 6. Replace the oil in the oil pan, check whether the crankcase ventilation pipe is intact, and clean the oil filter and diesel filter element. 7. Check whether the generator and starter motor are installed firmly, and whether the wiring head is clean and firm, and check whether the carbon brush and commutator are worn. 8. Check the tightness of the fan belt. 9. Check whether the wheel is installed firmly, whether the tire pressure meets the requirements, and remove the sundries embedded in the tread. 10. Check whether the filter screen at the oil inlet of the diesel tank is blocked or damaged, and clean or replace the filter screen. 2. After 500 hours of cumulative work for secondary technical maintenance, one shift is equivalent to one quarter. 1. Clean the fuel tanks, filters and pipelines, and check for corrosion and cracking. After cleaning, do not use fibers with fibers. Yarn ends, wipe the cloth. 2. Clean the torque converter, gearbox, check the wear of parts, and update the oil. 3. Check the bearing of the drive shaft and change the direction of the universal joint cross shaft if necessary. 4. Check the tightness of each part of the drive axle, whether there is oil leakage, and the air vent. Disassemble and inspect the main reducer, differential, and wheel reducer, adjust the bearing axial clearance, and add or replace lubricating oil. 5. Disassemble, inspect, adjust and lubricate the front and rear wheel hubs, and carry out semi-shaft shifting. 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 self-rotation amount of the steering wheel. 8. Disassemble and clean the gear oil pump, pay attention to check the wear of gears, housings and bearings. 9. Disassemble the multi-way valve, check the gap between the valve stem and the valve body, and do not disassemble the full valve if it is not necessary. 10. Check the steering knuckle for damage and cracks, the coordination of the kingpin of the steering axle and the steering knuckle, and check the wear of the joints of the vertical and horizontal rods and the steering arm. 11. Disassemble the tires, remove rust and paint on the rims, check the inner and outer tires and cushion belts, change positions and inflate according to regulations. 12. Check the connection and tightness of the hand brake components, and adjust the working stroke of the hand brake lever and foot brake pedal. 13. Check the battery. 14. Clean the water tank and oil radiator. 15. Check whether the shelf and frame are deformed, the rollers for disassembly and washing, and the attachments are reliably fixed, and if necessary, add welding firmly. 16. Disassemble and inspect the lifting cylinder, tilt cylinder and steering cylinder, and replace the worn seals. 17. Check the sensors, fuses and various switches of each meter, and adjust if necessary. 3. Disable maintenance of a new forklift or a forklift that has been stopped for a long time. Within two weeks of starting to use, for bearings that should be lubricated, when lubricating, use new oil to squeeze out all the old oil and lubricate it twice Above, pay attention to the following points at the same time: 1. Clean the dirt on the oil cap, oil plug and nozzle before lubrication to prevent the dirt from falling into the mechanism. 2. When injecting lubricant with a grease gun, it should be infused until the lubricant is squeezed out at the joint of each part. 3. Seasonal lubricants (motor oil, etc.) should be replaced in summer or winter. Any machine that wants to extend its service life is inseparable from the careful care of the operator and the manufacturer, instead of waiting for the machine to be broken and completely unable to rotate before checking the components, then it is already exhausted. If the broken machine has not been bought and used for a long time, it will definitely be blamed on the manufacturer who sells the machine, thinking that the quality of his machine is not good, but it is not.
