01. Battery charging and discharging of electric forklifts
(1) Make sure not to discharge the battery below 40% during use.
(2) Make sure the battery is in a well-ventilated environment when charging. Eliminate the use of open flame to avoid causing an explosion!
(3) When charging, use the appropriate charger to charge at the appropriate voltage, avoid charging the battery at too high a voltage.
(4) Cut off the power supply in time after charging is completed to avoid prolonged floating of the battery.
(5) Equalize charging of the battery every 500 working hours (3-4 months) to activate the inert oxides of the pole plate accumulated in the process of use.
(1) Inspection of battery surface, terminals, and battery connecting wires: to determine whether corrosive materials have crystallized and whether wiring connections are solid.
(2) Battery Surface Cleaning: Stain buildup will result in short-circuit energization of the battery surface, increasing the battery’s self-consumption and decreasing the battery’s standby and usage time. Here note to use a wet towel to clean the battery surface, dry towel wipe easily lead to battery surface static electricity or even fire.
The heat generated during the battery use and charging process will lead to the volatilization of water in the electrolyte, and the accompanying electrolysis reaction during charging will also lead to the reduction of water being electrolyzed into hydrogen and oxygen. Therefore, it is necessary to check the level of the battery regularly and maintain the dehydrated battery cells by adding water in time to replenish the lost water to ensure that the internal characteristics of the battery are maintained in a healthy state.
(1) Pay attention to the distilled water or deionized water when adding water for maintenance, the water containing impurities into the battery may increase the electrolyte resistance, resulting in increased battery power consumption, increased heat release from the battery case, greatly reducing the battery operating hours and battery life.
(2) The amount of water should be controlled at the height of the liquid level from the battery water port 2cm or so appropriate, generally most batteries on the market are equipped with liquid level indication function of the injection valve, according to the injection valve indicates the height of the filling of distilled water can be.
(3) Pay attention to add water to try to maintain a balanced level between the battery cells, electrolyte level differences will lead to differences in battery characteristics, which will affect the battery life in the long run.
Forklift maintenance is mainly based on the use of the cycle of maintenance, whether it is an electric forklift or internal combustion forklift need to be properly maintained maintenance, forklift service life can be better prolonged, the following is the introduction of electric forklift maintenance work.
Daily maintenance:
(1) Check the liquid level of the battery and the specific gravity of the electrolyte, and remove debris on the surface of the battery in time.
(2) Check the braking performance
(3) check the flexibility of the direction
(4) check the system oil, water, gas leakage situation
5） Check the working condition of the monitoring instrument and battery voltage.
6） Check the parts for abnormal noise and overheating phenomenon.
7） Check whether the wheel is cracked or abnormally worn.
8） Check whether the switch, pedal, joystick and button work properly.
9) Check whether the bolts and nuts of each part are loose or fall off, and focus on checking whether the axle, drive shaft and bridge bolts are loose.
(10) Check the flexibility of the joystick and add grease.
11) Add grease to each articulation point and pin sleeve.
The above is just a simple introduction to the maintenance of electric forklifts, the correct maintenance of electric forklifts to work better and improve efficiency.ZLIN is a manufacturer of electric forklifts, contact us to provide you with the latest offers and one-stop service.
