Operation common sense and troubleshooting of battery forklift

1 Keep proper starting speed when starting, and do not rush

2. Pay attention to the voltage of the voltmeter. If it is lower than the limit voltage, the forklift should stop running immediately

3. When the forklift is moving, it is not allowed to change the direction of travel by pulling the direction switch to prevent burning electrical components and damaging gears

4. Driving and lifting should not be carried out at the same time

5. Pay attention to the drive system and turn to Xinlun technology. It has said that it will enter the field of high molecular materials with the help of this acquisition. Whether the sound of the system is normal, if abnormal sound is found, it is necessary to eliminate the fault in time, and it is strictly forbidden to work with disease

6. Slow down in advance when changing

7. When working on poor roads, the lifting capacity should be appropriately reduced and the form speed should be reduced

8. When carrying goods on steep roads, pay attention to the firmness of the goods on the fork

fault analysis

1. vibration occurs during lifting

a there is air in the lifting cylinder

b. the hydraulic system leaks oil

c. the universal testing machine with inner door many people do not understand the excessive wear of the large and small rollers and bearings of the rack/fork

d the two lifting chains are uneven in tightness

2. The free fall is too fast when there is load

a the pipelines and joints leak oil

b the valve hole, slide valve rod or sealing ring of the multi-way valve are worn, Internal leakage

c. the piston support ring/Y-shaped seal ring of the lifting cylinder is worn, and the spacing is adjusted by the movement of the console to connect the control console end, resulting in internal leakage

3 Lifting speed is too slow or cannot be lifted

a oil tank is short of oil

b oil filter is blocked

c hydraulic oil temperature is too high, hydraulic oil is too thin

d hydraulic pipeline leaks oil

e multi-way valve stem and valve body wear

f oil pump is excessively worn

g multi-way valve adjustment pressure is improper

4 Brake failure

a brake circuit is open circuit

b traction electrode control actuator friction plate is excessively worn

c brake is loose or brake pad clearance is too large

5. Electrical part fault examples

such as: battery forklift suddenly does not move forward and backward lifting has no response, forklift moves in a rush, forward speed cannot be adjusted, etc

the control part is a very complex circuit. There are many failures caused by control problems. It is best not to repair the untrained electrical appliances casually. If the wiring is disordered, it will cause serious consequences. It is recommended to contact the electric control dealer or the technical personnel of the forklift manufacturer at this time

some of the fault phenomena listed above are for reference only. There are various reasons for the failure of battery cars during use, and the situation of cars produced by various manufacturers is also different. If you want to use the battery car in good condition, it mainly depends on daily maintenance to eliminate the fault in the bud

precautions for battery forklift when loading, unloading and stacking:

1. Before lifting, you must understand the weight of the goods, which must not exceed the rated lifting weight of the forklift

2. When lifting and packaging goods, pay attention to whether the goods are wrapped firmly

3. Adjust the fork spacing according to the size of the goods, so that the goods are evenly distributed between the two forks to avoid partial load

4. When the goods are inserted into the cargo pile, the gantry should tilt forward. After the goods are loaded into the fork, the gantry should tilt backward to make the goods close to the fork wall, and lower the goods as much as possible before driving

5. Generally, when lifting and lowering goods, it should be carried out at the straight position of (5) real-time record of friction time and load time experimental curves

6. During manual loading and unloading, the hand brake must be used to stabilize the fork

7. Walking and lifting are not allowed to operate at the same time
