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.

MYW hydraulic drive bulldozers

bulldozer hydraulic cylinder torque converter transmission is to rely on hydraulic works. Fluid flow in the Cascades, due to impact, friction, consumes energy, heat the oil, so torque converter transmission efficiency is relatively low. Bulldozer hydraulic drive system.

Bulldozer is a major mechanical earthmoving machinery, according to the walk is divided into two kinds of crawler and tires, because less tire bulldozer. This paper describes the structure and working principle of Bulldozer. The basic job of a bulldozer excavation is: A. B. earth C. shoveling dump.
Power greater than 120KW crawler dozer, the vast majority use hydraulic - mechanical transmission. Such Hydraulic Drive Crawler Bulldozers from the introduction of Japan's Komatsu D155 type, D85 type, D65 type three basic hydraulic dozer suppliers technology. After localization, stereotyped as TY320 type, TY220 type, TY160 type Basic track bulldozer suppliers.
