What are the wrong maintenance methods for high-altitude working cars

High-altitude operation car belongs to special operation vehicles, some owners of private cars are very careful maintenance, for high-altitude operation car is very ignore, this is a wrong approach, the following special auto network Xiaobian examples of several high-altitude operation car wrong maintenance methods, please the owners have to change, no then encourage.

When there is insufficient oil in the engine oil pan, the friction between bearings and journal will be poor lubrication due to the amount of oil, aggravate the degree of wear, and even cause the burning of tile shaft accident. However, if there is too much oil, the crankshaft handle and the big end of the connecting rod will produce severe agitation when the engine is working, which not only increases the internal power loss of the engine, but also increases the amount of oil splashed on the cylinder wall, resulting in burning oil failure. Therefore, with the car crane, the oil in the engine oil pan of the high-altitude working car should be controlled between the upper and lower engraving lines of the oil gauge.

There are many fasteners connected with bolts and nuts on the crane, which should be guaranteed to have sufficient pre-tightening force, but not too tight. If the screw is too tight, on the one hand will make the connector under the action of external force to produce permanent deformation; On the other hand, it will make the bolt produce tensile permanent deformation, preload decreases, and even cause the phenomenon of slipping or breaking.

The first charge of the battery is called the first charge, and the first charge has a great impact on the service life of the battery. If not charged, that is, add "water" directly used, the capacity of the battery is not high, the life will be shortened; If charged directly, it will also shorten the life span. Usually, the initial charge of the battery is after filling the electrolyte, and the battery can be installed and used for about 1 hour after charging with a small current.

Carefully care for high-altitude operation vehicles and other engineering vehicles, virtually for you to save costs, prolong the service life of vehicles.
