In the summer, do a comprehensive maintenance of the crawler truck, change the three filters and oil of the engine, replace or adjust the tape, check whether the performance of the fan, water pump, generator and compressor is reliable, and carry out maintenance, repair or replacement when necessary.

For the hydraulic system of the crawler truck, the quality of the hydraulic oil should be checked, and the hydraulic oil which is contaminated and cannot meet the normal use requirements should be replaced. Even if the hydraulic oil does not need to be replaced when entering the summer crawler truck, it is recommended to replace the hydraulic oil filter often to ensure the smoothness of the oil circuit and the cleanliness of the hydraulic oil entering the pump and valve to increase the heat dissipation. Clean the hydraulic oil tank that has not been cleaned for a long time to reduce pollution to restore the heat dissipation capacity of the oil tank. Check whether the hydraulic system piping, radiator and fan are reliable and whether the device that needs to be opened automatically is sensitive.

For crawler trucks working in high-temperature areas, increase the viscosity level of the oil, and check whether the cooling system and fuel system are smooth; replace the aging wires, plugs and hoses, check and tighten the fuel pipeline to prevent fuel leakage; clean the oil and dust on the engine body to ensure that the engine is "lightly loaded" and dissipates heat well. Clean the engine body of oil and dust to ensure that the engine is "lightly loaded" and dissipates heat well.

In order to cope with the effect of high temperature, additional cooling devices such as water tank and electronic fan can be prepared for emergency cooling at high temperature. High temperature can easily make the hydraulic power brake, steering and other systems, and the hydraulic pipeline is prone to air resistance in summer, which seriously affects the sensitivity of the action, therefore, in the use of the crawler truck, one should ensure that the amount of fluid is sufficient, and also prevent the pipeline from leaking, and if there is any abnormality in the operation, timely inspection should be conducted.

Summer is an important period for the maintenance of crawler trucks, and we should actively maintain our crawler trucks to make them last longer.
