Bulldozer convenience


The battery at low temperatures, the viscosity of the electrolyte increases, penetration decline, so that the battery capacity increases the internal resistance and terminal voltage decreased significantly,hydraulic track bulldozer not even discharge. Voltage drop so that the output power of the starter not required, it is difficult to reach the starting speed requirements.

Due to the low temperature starting the engine crankshaft speed is not high, the intake pipe temperature and gas flow rates are low, and poor fuel atomization quality, further increasing the difficulty for starting the engine.

At low temperatures, the viscosity of the oil in a large variety of poor mobility, to the operation of the roller makes it difficult, and exacerbated the mechanical wear and tear.

Practical at bulldozers

 which is the prototype of the first roller, appeared in 1860 in France steamroller, to further promote and improve the construction technology and quality gravel road, and speed up the pace. In the early 1900s, the world recognized the gravel road was the most excellent road and promotion in the world, the concept of compacted gradually been known, Rollers also will appear on each road construction site, the mid-19th century,hydraulic track bulldozer the internal combustion engine invention to the development of compaction equipment brought great vitality. The first internal combustion engine driven roller born in the early 20th century. Then there is the tire roller, sheep foot roller compactor wheel with light almost simultaneously produce,  Hydraulic Drive Crawler Bulldozers people still compactor compaction were studied, that weight gain can make the roller compactor line pressure increases, thereby increasing the pressure real effect.

Track Dozer efficiency

cheap track dozer is a blade mounted in front of the tractor load of road construction machinery, for bulldozing, leveling the building venues. Track Dozer in building construction such as roads, the bulldozers can complete the processing of the subgrade, roadside soil lateral Tim building height of not more than one meter of embankment along the centerline of the road to shoveling transfer, transport roadbed soil excavation and filling works, according to Mountain borrow built part - cut embankment. In addition, the bulldozer can be used for leveling the ground and accumulation of loose materials, removal of obstructions in the work area and the like.
