The use and maintenance of electric forklifts

Daily maintenance after each shift. 2. First-level technical maintenance, after a total of 100 hours of work, one shift of work is equivalent to two weeks. 3, secondary technical maintenance, cumulative work 500 hours, a shift of work is equivalent to a quarter. First, daily maintenance 1. Cleaning dirt, dirt and dirt on forklift trucks. The key parts are: fork carriages and gantry slides, generators and starters, battery electrode prongs, water tanks, and air filters. 2. Check the tightening condition of each part. The emphasis is on the fork support, the lifting chain tensioning screw, the wheel screw, the wheel fixing pin, the brake and the steering gear screw. 3. Check the reliability and flexibility of the foot brake and steering gear. 4, check the leakage situation, the focus is: each pipe joints, diesel tank, oil tank, brake pump, lift cylinder, tilt cylinder, water tank, water pump, engine oil pan, torque converter, transmission, drive axle, main deceleration Device, hydraulic steering gear, steering cylinder. 5. Remove the oil filter sediment.

Second, a technical maintenance in accordance with the "daily maintenance" project, and add the following work. 1, check the cylinder pressure or vacuum. 2. Check and adjust the valve clearance. 3, check the thermostat work is normal. 4. Check whether the multi-way reversing valve, lift cylinder, tilt cylinder, steering cylinder and gear pump are working properly. 5. Check if the gear shift 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 and check that the crankcase ventilation pipe is in good condition. Clean the oil filter and the diesel filter element.

8. 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 the commutator have worn. 9. Check the tightness of the fan belt. 10. Check if the wheel is firmly installed, whether the tire pressure meets the requirements, and remove the debris embedded in the tread. 11, due to carry out maintenance work and dismantle parts, when re-assembled after the forklift road test. (1) The braking performance under different degrees shall be free from deviation and meandering. On a steep slope, after the brakes are tightened, it can be stopped reliably. (2) Listen to the engine running under conditions of acceleration, deceleration, heavy load or no-load, etc., with or without abnormal sound. (3) After the road has been tested for a period of time, check for overheating at the brake, transmission, front axle housing, and gear pump. (4) Whether the fork carriage's lifting speed is normal and shaking or not. 12. Check whether the oil tank oil inlet filter plugs are damaged and clean or replace the filter.

Third, the second-level technical maintenance In addition to a level of technical maintenance of the project, and add the following work: 1, cleaning the fuel tanks, filters and pipelines, and check for corrosion, cracking, cleaning with no fiber The yarn ends, the fabric rubs. 2, clean the torque converter, gearbox, check the wear of parts, replace the new oil. 3, check the drive shaft bearings, if necessary, exchange the direction of the universal joint cross shaft. 4. Check the tightening of the various parts of the drive axle and whether there are any oil leaks or sparse ventilation holes. Check the main reducer, differential, wheel reducer, adjust the axial clearance of the bearing, add or replace the lubricant. 5, inspection, adjustment and lubrication of the front and rear hubs, semi-axle transposition. 6. Clean the brake and adjust the gap between brake drum and 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 and check the gap between the valve stem and the valve body. If it is not necessary, do not open the safety valve. 10. Check whether the steering knuckle has any damage and cracks, the matching of the kingpin of the steering axle and the steering knuckle, and check the wear of each joint of the vertical and horizontal tie bars and the steering arm. 11. Remove the tires, remove the rust paint on the rims, check the inner and outer tires and pads, replace them and inflate them as required. 12. Check the fastening of hand brake parts and adjust the working stroke of hand brake lever and foot brake pedal. 13, check the battery electro-hydraulic proportion, if it does not comply with the requirements, must remove the charge. 14, cleaning tank and oil radiator. 15. Check if the shelf and frame are deformed, whether the washing roller is removed or not, and whether the attachments are fixed reliably. 16. Check the lifting cylinder, tilt cylinder and steering cylinder and replace worn seals. 17, check the instrument sensors, fuses and a variety of switches, if necessary, adjust. Fourth, the entire vehicle lubricates the new forklift or the forklift after a long period of cessation of work. Within two weeks after the start of use, for bearings that are to be lubricated, they shall use the new oil to completely extrude the oil and lubricate twice during lubrication. Above, at the same time should pay attention to the following points: 1. Before lubrication, the dirt on the oil cover, oil plug and grease nipple should be removed to prevent the dirt from falling into the inside of the mechanism. 2. When using a grease gun to inject the lubricant, the components that are pressed into each part should be combined with the extrusion lubricant. 3. Seasonal lubricants (oil, etc.) should be replaced in summer or winter.
