Research bulldozer with hydrostatic drive system

Hydraulic drive system bulldozers  With the western development and the country's infrastructure accelerated pace for the development of China's construction machinery industry provided a rare opportunity, domestic manufacturers have expanded their product range in the field belongs, hydrostatic driven dozer  use some advanced technology to develop their own products or through the introduction of foreign advanced technology to improve product quality. And made some satisfactory achievements. Hydrostatic bulldozer But we should also see that the gap between itself and the presence of foreign advanced level, mainly in product durability is poor, low degree of automation, and environmental pollution,

a serious shortage of technological innovation, even if we are a small part of the product reached a level the international advanced level, but some of the key technologies of these products still lies in the hands of foreign enterprises. After China's accession to WTO, foreign advanced technology and products of the influx of China's machinery products market project has also caused a serious impact. For this reason countries have proposed a "construction machinery" Tenth Five-Year Development Plan. " Although since the 1980s, our country through the introduction, digestion and absorption, the traditional mechanical, hydraulic mechanical bulldozer was close to or reach the level of similar foreign products from the manufacturing capacity, production scale, technology level.

Bulldozer is not on the main clutch engagement

Main reasons: short pins linking panel off; mobile sets anti-loaded hammer; repair process is not the mechanical Swamp Bulldozer main clutch cover, check whether the movement set off short pin and hammer mobile sets is installed backwards ( If the anti-loaded hammer, will not enter the adjustment plate movement sets), mobile sets can be removed, if necessary, re-caulked short pin, and installed regulating disk. If the Mechanical Track bulldozer to carry the main clutch lever shaft is mounted in place, should be required to adjust the lever shaft in place.

Highlands Dozer

Composition and working principle of hydraulic and electrical systems bulldozers bulldozers knowledge of safe operation and maintenance of knowledge, type hydrostatically drive crawler tractor, the overall structure and application, bulldozers major component structure and working principle parts, bulldozer common failure modes and causes of failure, knowledge of other typical form bulldozer damage and repair methods bulldozer wearing parts, elevated driving hydrostatic driven earthmover, hydraulic bulldozer, Wheel bulldozer and military bulldozers, which are intended to expand the students' professional horizons. Highlands Dozer is a classic earthwork machinery, widely used in highway, railway, construction, utilities, ports and irrigation and water conservancy construction projects.

Suspension is a bulldozer blade with self-propelled earth-moving machinery

Bulldozer is Crawler Earthmover  or tractor tire tractors special chassis as the host, together with the suspension blade (with The device comes with a ripper) self-propelled earth-moving machinery. Bulldozer at work, the shovel knife buried in, rely on forward travel drive system provides power to complete the cutting, pushing soil work, sometimes used as a filling, flat, tillage work. Hydrostatic driven earthmover  used to lift heavy physical labor, accelerate the construction schedule, to ensure construction quality. So it is a widely used in construction, road building, mining, agriculture, forestry, construction and other areas of basic national defense construction machinery.

Currently, hydrostatic drive and control technology in vehicle systems has been widely used and considerable progress, particularly with low-speed track job means moving vehicles. But in the bulldozers, earth-moving machinery in the application of domestic premature. With the development of China's highway construction, the number of construction projects for construction machinery has increased significantly, and the quality have higher requirements. Bulldozer plays an important role in construction projects, its technical performance, operational control in the form of directly affect the performance and efficiency of the bulldozer.

Bulldozer is an engineering vehicle for bulldozing, leveling construction field

Hydrostatic driven dozer is an engineering vehicle, equipped with a large metal front dozer blade, dozer blade down when using forward chipping and push the mud, sand and stones, dozer blade position and angle can be adjusted. Bulldozer digging can be done individually, earth and dump work, with flexible operation, convenient rotation required Face small, travel speed and other characteristics. It is mainly applied to three types of soil in a shallow cut short transport, such as land clearing or leveling, excavation depth of excavation and backfill little push to build highly little roadbed.

MYWhydraulic drive system bulldozers in front of the tractor loaded blade mounted road construction machinery, for earth-moving, flat building site and so on. For example, in the construction of the road construction, the bulldozers can complete the process of 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, take the mountain construction of part - cut soil subgrade. 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.
