1、 Chassis engine preheating:
Warm up the engine at the standard idle speed to ensure that all parts of the engine are fully lubricated.
2、 Brake system:
Check or replace the air dryer in the air system in time; drain the water condensed in the air reservoir to prevent icing.
3、 Cooling system:
The long-term anti freezing and anti-corrosion coolant used in the cooling system can not freeze at - 20 ° C (based on the data of various chassis). If it is lower than - 20 ° C, the concentration of the coolant should be increased appropriately, and the maximum concentration should not exceed 60% to avoid corrosion of the cooling system.
Regularly check the level and specific gravity of battery electrolyte. The liquid level should be 10-15mm higher than the plate, and the specific gravity should be above 1.24g/cm3.
Every 500 km, check whether the connecting clip between the battery electrode post and the wire is loose, and whether the working condition of the battery is normal.
2、 Hydraulic system:
If the ambient temperature is lower than the minimum specified temperature of hydraulic oil (about 10 ℃), the hydraulic system should be preheated, and the engine should be idled for 10-15 minutes without the mixing drum running.
2. It is recommended to use H32 or l-hm32 (nas9 grade) hydraulic oil in winter in northern China. Note: it is strictly forbidden to mix hydraulic oil of different brands and models. When the brand of hydraulic oil needs to be changed, the oil tank must be thoroughly cleaned and the oil filter must be cleaned or replaced at the same time.
GL-5 gear oil is used, and oil of different viscosity grade is used in different working environment
In the cold winter season, after each use of the equipment, the water in the water tank and pipeline should be drained to prevent freezing.
5、 Mixing drum:
It is suggested that the car owners should install insulation sleeve on the mixing drum during winter construction.
