Applicable model: various models 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 shall stop running immediately.
3. When the forklift is moving, it is not allowed to change the driving direction 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 whether the sound of the driving system and steering system is normal. In case of abnormal sound, the fault shall be eliminated in time. It is strictly prohibited to work with disease.
6. Slow down in advance during the transition.
7. When working on poor roads, its importance shall be appropriately reduced, and the driving speed shall be reduced.
8. When carrying goods on steep roads, pay attention to the firmness of the goods on the fork.
Serial number
Failure phenomenon and cause analysis
1. Vibration during lifting
A. There is air in the lifting cylinder
B. Oil leakage of hydraulic system
C. Excessive wear of large and small rollers and bearings of inner gantry and fork frame
D. Uneven tightness of two lifting chains
2. Free sliding too fast under load
A. Oil leakage in pipes and joints
B. The valve hole / slide valve rod or sealing ring of multi-way valve is worn, resulting in internal leakage.
C. The piston support ring / Y-shaped seal ring of lifting cylinder is worn, resulting in internal leakage.
3. The lifting speed is too slow or cannot be lifted
A. Oil tank is short of oil
B. Oil filter blocked
C. The hydraulic oil temperature is too high and the hydraulic oil is too thin
D. Oil leakage of hydraulic pipeline
E. Wear of multi-way valve stem and valve body
F. Excessive wear of oil pump
G. Improper pressure adjustment of multi-way valve
4. Brake failure
A. Open circuit in brake circuit
B. Excessive wear of friction plate in traction electrode control actuator
C. The brake is loose or the brake pad clearance is too large
5. Some electrical faults, such as: the battery forklift suddenly does not move forward and backward, there is no response to lifting, the forklift rushes and rushes, the forward speed cannot be adjusted, and so on.
The control part is a very complex circuit. There are many faults caused by control problems. It is best not to repair the untrained electrical maintenance personnel casually. If the wiring is chaotic, 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 fault phenomena listed above are for reference only. There are various reasons for the failure of battery cars in 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 during loading, unloading and stacking of battery forklift
1. Before lifting, you must know the weight of the goods, which shall not exceed the rated lifting capacity of the forklift.
2. When lifting and packaging goods, pay attention to whether the goods are wrapped firmly.
3. Adjust the space between forks according to the size of 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 shall tilt forward. After the goods are loaded into the fork, the gantry shall tilt back to make the goods close to the fork wall, and lower the goods as much as possible before driving.
5. The lifting of goods shall generally be carried out in a vertical position.
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.
