In November 15th, most parts of the North began to stop work, excavators did not work, the winter break of several months officially began. In the idle period of the excavator, a friend must not ignore the love of the machine, the 9 major points of attention in the winter parking and excavator do you know?
1. winter into the off-season construction, excavator before the idle storage, the first should be a comprehensive physical examination of the excavator, check whether there is a failure and parts loosening, but also love the dust dirt on the fuselage clean.
2. when storing the excavator in winter, remember to keep the bare oil tank back as far as possible to avoid the corrosion of the oil cylinder in wet environment such as snow in winter, so as to prevent the oil cylinder from rusting. If it can't shrink because of the cause of the site, a layer of butter can be applied to the surface of the piston rod.
3. the winter temperature is especially cold. When the excavator needs a long time to stop, the coolant in the engine should be emptied. It should also be observed whether the oil oil is normal, and the old oil is easy to corrode the engine parts.
The position of the 4. excavator should also be paid special attention. It is best to stop in the dry indoor environment. Because of the limit of conditions, most a friend can only stop the excavator outside. At this time, a more flat place should be chosen, and it can not be placed in wet, salt, dust and so on for a long time.
5. when the excavator is suspended outside for a long time, remember to cover the bare oil cylinder with a cloth. Out of outdoor safety considerations, check carefully whether there are valuables in the cab and inflammable and explosive things when the excavator is stored.
6. the excavator can not be completely ignored. The engine needs to start and run once a month to avoid problems for a long time. When the antifreeze fluid is insufficient, it should be added and restart in time.
7. the winter maintenance can not be lost, the diesel should be replaced with the -10~30 model, and the light diesel oil should be selected with low condensation point and good ignition performance; the oil should be changed into the thickening oil suitable for the weather in the area where it is located; at the same time, the oil leakage of the hydraulic system should be checked, and some changes should be made.
8. because of the low temperature, the battery is easy to feed in winter. The battery should be removed and stored in a warm room.
9. the air conditioning system should also be checked regularly. The air conditioner should be operated for 3 to 5 minutes each month, so that it will not be damaged for a long time.
