The time is already autumn and winter, the temperature is getting colder, and the maintenance of aerial vehicles is particularly important. How to maintain the maintenance of aerial vehicles in autumn and winter? Can start from the following aspects: 1. Check the tyre pressure of the aerial tires. The tires of high-altitude trucks are made of rubber, and the rubber will become hard and brittle due to the lowering of the temperature, the coefficient of friction will be reduced, and leakage and tying will occur. In summer, tire pressure cannot be too high due to high temperatures. On the contrary, in the autumn, because the temperature is relatively low, the tires will have to increase air pressure. Also, check the tires frequently for significant signs of injury, scratches, etc. The debris in the tread must be cleaned regularly. 2. Clean the ventilation system of aerial vehicles. Autumn and winter, allergic rhinitis and asthma in high season. If you are allergic to dust and pollen, it is best to install a filter in the air conditioning system so that dust, pollen, and bacteria can be rejected outside the car. In addition, the air circulation in the cab must be improved to improve the air quality in the car. 3 , to do a clean job inside the aerial vehicle. You can use a towel or sponge with soapy water or detergent to scrub every corner of the dashboard. Clean the surface of the chemical fiber before using a vacuum cleaner to suck the dust off, then infiltrate with a special textile cleaner for a few minutes. After the dust is dissolved, wipe it again with a towel. If there is no special detergent, you can change it with soapy water or dishwashing liquid. Leather products can be wiped with a towel with a little clean water. 4, replace the hydraulic oil. In the colder weather in the north, it is necessary to replace the high-altitude operation without hydraulic oil with anti-freezing hydraulic oil. Parking is also in the warm room at night.
