Use condition and operation characteristics of logging bulldozer (1)       

Compared with the ordinary operation type earthwork bulldozer, bulldozer logging more complex conditions, based on both the smooth operation of the earth, but also consider logging, remove stumps, hauling and wrecker operation condition. In addition, the operating environment of logging bulldozers is mainly the dense forest, primitive forest or semi developed logging field, such as the tropical rain forest in Southeast asia. Therefore, the characteristics of the logging bulldozer working condition has the variability and diversity:

(1) tropical logging market has large leaves, dust and insects, these can easily be blocked and filter air filter air inhalation, causing adverse problems even the engine early wear, affecting the normal work of the engine. At the same time, because the environment temperature is high, if the radiator is blocked into the leaves, it will lead to overheating of the engine. When the engine works at high temperature, the lubricating oil entering the top of the piston and the combustion chamber will generate carbon in the case of high temperature and oxygen deficiency, and the coke will generate hot spots, which will cause the engine to produce spontaneous combustion or deflagration. Engine overheating and deflagration can cause thermal deformation of cylinder block and cylinder head, and even crack or warpage, resulting in the compression force of the cylinder drops, reducing engine efficiency. In addition, the high temperature will make the lubricating oil thinner, lower viscosity, not easy to form oil film on the body surface, aggravating wear and tear of parts, thereby reducing the life.

(2) in the operation of logging bulldozer vehicle appearance often and has cut down the branches of the trees and other lodging collision on the stamp, especially before the hood and the upper hood part is particularly prone to peripheral parts damage deformation or cracking.
