Applicable models: various types of battery forklifts
1. Maintain proper starting speed when starting, and should not be excessive.
2. Observe the voltage of the voltmeter. If the voltage is lower than the limit voltage, the forklift should stop running immediately.
3. When the forklift is walking, it is not allowed to change the driving direction by pulling the direction switch to prevent burning of electrical components and damage to 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 the steering system is normal. If an abnormal sound is found, the fault should be eliminated in time. It is strictly forbidden to work with the disease.
6. Slow down in advance when changing.
7. When working under poor road conditions, its importance is appropriately alleviated, and the driving speed should be reduced.
8. When carrying goods on a large slope road, pay attention to the firmness of the goods on the fork.
Serial number
Failure phenomenon Cause analysis
1. Vibration occurs when lifting
A. There is air in the lifting cylinder
B. Oil leakage of hydraulic system
C. Excessive wear of inner roller, fork roller and bearing
D. The two lifting chains are uneven
2. Free fall too fast when there is load
A. There is oil leakage in the pipelines and joints
B. The valve hole/spool stem or seal ring of the multi-way valve is worn, causing internal leakage.
C. The piston support ring of the lifting cylinder/Y-type seal ring is worn out and internal leakage occurs.
3. The hoisting speed is too slow or cannot be hoisted
A. Fuel tank is short of oil
B. The oil filter is clogged
C. The temperature of the hydraulic oil is too high, the hydraulic oil is too thin
D. Oil leakage of hydraulic pipeline
E. Multi-way valve stem and valve body wear
F. Excessive wear of oil pump
G. Improper pressure adjustment of multi-way valve
4. Braking failure
A, the brake circuit is broken
B. Excessive wear of friction plates in the traction electrode control actuator
C. The brake is loose or the brake pad gap is too large
5. Partial failure of electrical appliances: For example, the battery forklift suddenly does not move forward and backward, the lift does not reflect anything, the forklift moves one by one, the forward speed cannot be adjusted, etc.
The control part is a very complicated circuit. There are many failures caused by the control problem. It is best not to repair the electrical maintenance personnel without training. If the wiring is chaotic, it will cause serious consequences. It is recommended to contact the electronic control dealer or the technician 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 the battery car during use, and the conditions of the cars produced by various manufacturers are also different. If you want to use the battery car in good condition, it mainly depends on daily maintenance and eliminates the failure in the bud.
Matters needing attention when loading and unloading stacks of battery forklifts
1. The weight of the cargo must be known before lifting. The weight of the cargo must not exceed the rated lifting weight of the forklift.
2. When lifting and packaging goods, pay attention to whether the goods are bandaged firmly.
3. According to the size of the goods, adjust the distance between the forks so that the goods are evenly distributed between the two forks to avoid partial load.
4. When the cargo is inserted into the stack, the mast should be tilted forward. After the cargo is loaded into the fork, the mast should be tilted backwards, so that the cargo is close to the fork wall and the cargo is lowered as much as possible before it can be driven.
5. When lifting goods, it should generally be carried out in a vertical position.
6. During manual loading and unloading, hand brakes must be used to stabilize the fork.
7. Walking and lifting are not allowed to operate at the same time.
