Use condition and operation characteristics of logging bulldozer (two)       

(3) the logging bulldozer working environment of high temperature and high humidity, will cause the aging speed of electrical components and wiring harness up; tropical rainforest in hot and humid environment is easy to cause short circuit or electrical conductivity variation; in addition, the hot and humid environment will accelerate the evaporation of electrolyte, shorten the service life of the battery.

(4) logging bulldozer workplace is mainly forest, the space is small, high temperature working environment (40~55 C), gas and noise are easy to spread, which not only cause pollution to the environment, will also reduce the bulldozer technical performance and operation efficiency, serious damage to the operator's health. In addition, the logging bulldozer generally use non enclosed cab (canopy), although the driving shed is also equipped with anti roll anti litter protection device, but in practical work, because the trees lodging unsafe and uncertain factors will have impact on the driving shed so, there are some security risks.

(5) in the clean high density of trees or earthwork, logging type bulldozer is often accompanied by violent vibration, resulting in loose bolts, hydraulic pipeline leak and other issues, and other parts of crawler bulldozer is easy to wear and vibration and premature failure or scrap.

Therefore, in the design must consider the characteristics of logging bulldozer actual operation, which has protective (vehicle safety and the safety of the operator) performance and response to high temperature and high humidity environment, in order to improve the logging bulldozer under the condition of changeable work ability and efficiency.
