In the cold winter, excavators in many areas are still working. The environmental temperature has certain influence on each part of excavator. Therefore, if the excavator is not maintained enough in this season, it will cause failures. This article will summarize some precautions for the maintenance of the cooling system, glass, air conditioning and chassis of the excavator in winter. For reference only.
1. Maintenance of cooling system in winter
Under low temperature conditions, attention should be paid to the maintenance of the cooling system. In winter, antifreeze is usually added to the excavator cooling system. The proportion of antifreeze added to the cooling system shall be the proportion at the lowest temperature. Special attention should be paid to the long replacement cycle of antifreeze, generally 1-2 years. In winter, check whether the antifreeze is normal and whether it needs to be replaced.
2. Cleaning and maintenance of excavator glass
The temperature in winter is relatively low, and the excavator will be placed for a long time in most areas. The maintenance of the excavator at this time cannot be ignored. Keep the wiper away from the windshield to prevent freezing. When cleaning the glass, the water spray bottle needs to add antifreeze to prevent the water on the bottle and glass from freezing.
3. Check the air conditioner and fan belt
There are a lot of seasonal maintenance work for excavators. Although the air conditioner is not often used in winter, it also needs to be checked frequently. Avoid failure caused by not using for a long time. In addition, check whether the fan belt and air conditioning belt are aging to avoid belt breakage.
4. Inspection and maintenance of excavator chassis
In winter, it is necessary to inspect the nuts, bolts and pipelines of the excavator chassis. Including checking for looseness and pipeline leakage. It is also necessary to grease the lubrication points of the chassis, paint off and paint anti-corrosion treatment, etc.
