With the arrival of severe winter weather, a series of key considerations and work preparation recommendations are provided below to ensure the normal operation and efficient use of vehicles and various types of equipment In terms of equipment maintenance, the first step is to replace antifreeze in a timely manner to avoid freezing and cracking of the water tank. It is recommended that antifreeze should be used for no more than 2 years or 60,000 kilometres, and its freezing point should be more than 10°C below the local minimum temperature, to ensure that it can still play a good antifreeze effect at extreme low temperatures. Meanwhile, in severe cold weather, -10 diesel should be used to prevent diesel from starting due to low temperature wax precipitation. In addition, the chassis storage tank needs to remove the residual water in time and replace the drying canister cartridge to prevent water droplets from entering the braking system and icing up, leading to braking failure. Regularly change the gear oil in the transfer case/reducer to ensure stable gear oil performance and prevent the reducer from freezing and cracking. Protection of the battery is also critical. Fully discharged batteries can freeze and be damaged at low temperatures. If the battery freezes, it needs to be defrosted before charging. For vehicles not in use for a long time, it is recommended to disconnect the negative battery cable or remove the battery and store it upright in a dry environment at 0-30°C and recharge it before reloading it for use. Vehicles that have been parked for a long time also need to start the engine regularly and switch on the air-conditioning at idle speed to protect the air-conditioning compressor from damage. Before switching on the air-conditioning, the engine needs to be allowed to idle for at least 10 minutes. At the same time, in order to ensure the normal operation of the wiper system, the wiper jug should be filled with special glass water. When using the water pump in cold weather, you need to change the qualified oil and control the oil filling volume between 850-900ml. If the oil filling volume is too large, it may lead to slight oil leakage from the oil plug vent hole, but this is a normal phenomenon. In terms of work preparation, the engine needs to be warmed up before driving, and then drive after the water temperature and oil pressure are normal. If any abnormality is found, it should be overhauled immediately. Before construction, you need to clean up the ice in the sink, and preheat the pumping system to the oil temperature of 20 ℃ or more before starting construction, in order to protect the pump and hydraulic components from damage. After construction, it is necessary to wash the pipe to clean up the residual material in time to prevent the concrete in the pipe from freezing and then not being able to wash the pipe. At the same time, the water should be drained from the water tank and the outrigger tank and pump to prevent freezing. When releasing water, the water pump and water gun should be opened as well as the rubber plug of the water tank, and the empty machine pumping for 3 minutes to ensure complete emptying. Through the implementation of the above measures, you can effectively reduce the impact of severe cold weather on vehicles and equipment to ensure its stable operation and efficient use.
