Bulldozer was widely straight shovel

hydraulic track bulldozer uses a wide range of earth-moving machinery is the most commonly used operating machinery, occupies an important position in the earthwork construction. But because there is no wing blade, capacity is limited, in the process will cause earth leakage on both sides, it is not too long haul, otherwise it will reduce production efficiency. Typically small and medium haul bulldozer was 30 ~ 100 m, a large bulldozer haul generally not exceed 150m, bulldozer economic haul distance 50 ~ 80m.
When the transport conditions, earth-moving equipment was lifted lift cylinders, hanging in front of bulldozers; when the bulldozer into the working condition, the lower earth-moving equipment, the blade into the ground, can bulldozing forward, rewind can ground. When the bulldozer for tractor operations, the soil can push device removed.
Typically, hydraulic drive system bulldozers pushed forward dig earth, when the flat ground or piled loose material, widely it straight shovel; shovel or unilateral spoil hillside, often using oblique shovel; shovel cut on the slopes hard soil or digging ditches, using the side shovel.

The main purpose of bulldozers and construction

Mechanical Highlands dozers MYW in front of a crawler tractor or tractor tire mounting earth-moving equipment and operating mechanism of self-catering facilities machinery, mainly used for cutting excavation, backfill excavation, elimination of barriers, clearing the plot snow, land leveling, etc., can also be done short distance transport of bulk material shovel and stacking operations.
Bulldozer with ripper, can be turned loose Ⅲ, Ⅳ level above the hard soil, soft rock or rock chisel crack layer, scrapers and bulldozers to carry out excavation work, can also be used Highlands Bulldozer of direct push scraper blade scraper shovel to increase capacity (so-called shovel bulldozer aid), but also to assist the grader or a scraper to complete the construction work in order to improve the operating efficiency of these machines

History and the type of bulldozer

Bulldozer is a major mechanical earthmoving machinery, according to the walk is divided into two kinds of crawler and tires, because less tire bulldozer.
120KW of power greater than Crawler Earthmover, the vast majority use hydraulic - mechanical transmission. Such bulldozer from the introduction of Japan's Komatsu D155 type, D85 type, D65 type three basic bulldozer manufacturing technology. After localization, stereotyped as TY320 type, TY220 type, TY160 type Basic bulldozer. In order to meet user demand for the use of work conditions, our swamp hydraulic track dozermanufacturer on the basis of the above three basic bulldozer on, expanding product variety, the formation of three series of bulldozers. TY220 bulldozer products, including TSY220 Wetlands bulldozer, TMY220 type desert bulldozer, TYG220 type plateau bulldozer, TY220F Forest logging bulldozer, TSY220H model sanitation bulldozers and pipelayers DG45 type and so on. TY320 and TY160 type series bulldozer also expanding similar products. TY160 series there TSY160L ultra wetlands bulldozer and push TBY160 type Pa machines.

Bulldozer

Biggest bulldozer is an engineering vehicle with a large metal front dozer blade, dozer blade down when in use, and push forward chipping 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 dig short run, such as land clearing or leveling, Currently the world's small swamp bulldozer excavation depth of excavation and backfill little push small building height roadbed.
