Winter temperatures plummet! How to ensure efficient work of aerial vehicle equipment, the electric

In terms of battery capacity, due to severe cooling, the battery capacity of aerial work platforms in winter is based on a temperature of 25°C. For every 1°C drop in temperature, the battery capacity decreases by 1%. In winter, when the battery is in a low-temperature environment, the battery cycle capacity is relatively low, the viscosity of the electrolyte increases, the chemical reaction resistance increases, and the charging time may be shortened (charge 70% below 5°C). The charging capacity is 60%--70%, and the discharge capacity is 50% %--60%, the mileage is reduced (cannot run far). Calculation of mileage in winter (70% charging times 60% discharge is approximately equal to 42% of mileage in summer). It is recommended to charge indoors!
All diesel aerial vehicles need to be preheated before starting. The preheating method is to turn on the emergency stop switch and wait for 15 minutes before starting. If it cannot start, wait another 15 minutes. Do not start continuously. Continuous starting will cause the battery to lose power! Diesel needs to be purchased - No. 10 diesel and add anticoagulant!
Precautions for using electric aerial vehicles:
1. When the temperature drops in winter, aerial work vehicles should be parked indoors as much as possible to avoid sudden drops in temperature at night, which will affect battery life.

2. When using electric equipment, avoid complete discharge. When using the low-battery alarm, you should charge it immediately to avoid battery discharge and damage to the battery.

3. After using electric equipment, you should try your best to charge it all night long, recharge it during the lunch break, and recharge it once a month when it is not in use to ensure that the battery is charged and fully charged.

4. Check whether the battery body is damaged, cracked, or leaking. If maintenance is required, check the battery electrolyte level to ensure it is sufficient;

5. High air humidity in winter can easily lead to corrosion and crystallization of the battery pile heads. Check the battery electrode terminal piles regularly and apply Vaseline or butter.

          Precautions for using fuel-powered high-altitude vehicles:

1. Choose a suitable parking location. The temperature drops in winter. Aerial work vehicles should be parked indoors as much as possible. If parked outdoors, try to avoid facing the wind as much as possible to avoid diesel wax deposits caused by sudden drops in temperature at night. When the equipment is parked, the pole should be in a stowed state as much as possible. If the pole is in a lifted state, make sure there is space under the pole and no other obstacles to prevent property damage caused by sudden drop of the arm.

2. Select the appropriate diesel fuel according to the local ambient temperature to avoid waxing or clogging of the diesel fuel at low temperatures, which may cause the engine to fail to start.

3. Choose the appropriate engine oil and hydraulic oil. The appropriate engine oil should be selected according to the local ambient temperature to ensure that the engine can start coldly. Hydraulic oil: The grades of hydraulic oil are generally 32#, 46#, and 68#, among which 32# hydraulic oil is suitable for belt areas.

4. Choose the appropriate antifreeze. The freezing points of antifreeze include -15°C, -25°C, -30°C, -40°C, etc. Under normal circumstances, you should choose one that is more than 10°C lower than the lowest temperature in the area. should. In winter, you should choose to use antifreeze with a low freezing point. The lower the freezing point, the stronger the antifreeze performance of the antifreeze.

5. Fully preheat before starting and preheat multiple times. Winter temperatures are low, and the engine must be fully preheated before each cold start. Specific method: After turning on the red emergency stop switch on the control panel, hold the preheating button for about 10 seconds, and then push the start button to start the engine. When the temperature is lower than -15℃, multiple preheating times are required, and it is recommended to preheat 2-3 times. Special note: For equipment without a preheating button, wait about 10 seconds after turning on the red emergency stop switch before starting.

6. Avoid frequent starts that cause the engine to fail to start the first time. Do not start immediately for the second time. Please preheat before starting again to avoid frequent starts that may cause the starting battery to lose power or the starter motor to burn out.

7. Pay attention to the amount of diesel oil. When using the equipment, you should pay attention to the amount of diesel oil in time to prevent the diesel from running out and sucking air. If it is started frequently at this time, it will easily cause the battery to lose power and delay normal operations.

8. Turn off the power in time. After the work is completed, the power supply of the vehicle must be turned off in time to avoid the continuous discharge of the battery causing the equipment to be unable to start. The specific method is: turn off the red emergency stop switch on the lower controller of the machine and turn the key switch to the neutral position. If conditions permit, it is recommended to remove the negative cable of the starting battery.

9. Drain water in time. When the ambient temperature reaches below 0°C, the water in the diesel filter element or oil-water separator is very easy to freeze, affecting the normal operation of the engine. Therefore, after the work is completed, the water in the diesel filter element or oil-water separator must be drained promptly to prevent the possibility of freezing.

10. When the frame and wire rope encounter wind, snow, ice and snow, it is necessary to promptly clean the snow and ice on the arm and pull plate to prevent personal injury when falling from high altitude. Check the length sensor and other exposed components to avoid direct or indirect damage caused by freezing; Check and clean the ice in the pulley rope groove promptly to prevent the pulley from rotating.
