The hydraulic system of the excavator will burst pipes under high-temperature environment, oil leakage of joints, high temperature will cause the sealing of hydraulic components to be reduced, causing burst pipe leakage. In addition, the high temperature will also expand the hydraulic components, causing the valve core and valve body to be stuck, forming a local high temperature and causing the tube to burst. Changing the tube in summer is like taking a bath!

In the summer, due to the principle of thermal expansion and contraction of the metal, the circuit of the construction machinery will easily cause the line skin to crack, which will lead to the leakage of the wire and cause a short circuit failure; serious fire will result! If you check the machine and find that the circuit is seriously aging or there is leakage of the wire, please replace or repair it in time to avoid accidents!

Under high temperature, it is easy to cause the engine to "boil", which lowers the viscosity of the engine oil and causes failures such as pulling cylinders and burning tiles! Note: Do not rush to open the radiator cover after opening the pot, because the hot water may be burned. Remember not to use cold water to directly flush the engine to cool down, this will cause the engine block and other parts to burst! Pay attention to water temperature and oil temperature during construction in summer!

In summer, the temperature of the air conditioner in the cab is low, and the high temperature in the direct sunlight will cause small cracks in the glass of the cab. Because of the large temperature difference between inside and outside or splashing water, the cracks expand and even burst. Therefore, the temperature of the air conditioner should not be too low, the human body is suitable.
