Full hydraulic crawler bulldozer is a major mechanical earth-moving machinery, by way of walking into the crawler and tire two. Because less tire bulldozer. This paper describes the structure and working principle Shantui crawler bulldozer.
Power greater than 120KW swamp hydraulic track bulldozer, the majority adopts hydraulic - mechanical transmission. Such a bulldozer from the introduction of Japan's Komatsu D155 model, D85 type, D65 bulldozer type three basic manufacturing technology. After localization, setting type for TY320, TY220 type, TY160 type Basic bulldozer. In order to meet user demand for a variety of conditions using the work, our bulldozer manufacturers produced 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 type sanitation bulldozers and pipelayers DG45 type and so on. TY320 TY160 series Mechanical Track bulldozer type and similar products are also expanding. TY160 series there TSY160L ultra wetlands bulldozer and push Grilled TBY160 type machines.
Product development to expand the kinds of bulldozers, both to meet the different conditions of work premise adaptability, but also essential and basic components maintain maximum versatility (or interchangeability), which use the service for the Pan-blog users to bring extremely convenient. To facilitate the purchase of accessories, production plants have retained a number of Japan's Komatsu parts, only modification to design parts, was dubbed themselves the number of manufacturers. Crawler bulldozer mainly by the engine, transmission, equipment, electrical department, cab and hood and other components. Among them, the mechanical and hydraulic transmission system also includes a torque converter, the coupling assembly, planetary power shift transmission, central transmission, steering clutches and steering brakes, final drive and walking system. Power output means (PTO) 10 by way of gear and spline connection driven hydraulic system working pump P1, variable speed torque variable speed pump hydraulic system P2, hydraulic steering and braking systems steering pump P3; 8 represents a secondary sprocket Straight final drive gear transmission mechanism thought (including left and right final drive assembly); 9 includes crawler track shoe assembly, frame and hanging device assembly units, including travel system. This article will focus on the first volume in the above transmission torque converter, planetary power shift transmission, steering clutch and steering structure brake failure and exclusion principle and the hydraulic system.
Bulldozers domestic 102KW following such type T140, T120 type, T70 type and other small power bulldozers, which are mechanical drive transmission system of the type including a clutch and mechanical transmission and so on. Such bulldozer in my domestic sales are larger; its structure is simple, producing an earlier era, and use the more understanding, use and maintenance is relatively easy.

Bulldozer trapped car self
When the Swamp crawler dozer in a great location moisture or rain in muddy sections were bulldozer operations, inspection easy trap car phenomenon. There are two ways to save themselves after the trap car.
(1) If the bulldozer on the ground to the front of the car is not too deep depression when the Hydrostatic truck Bulldozer, dozer manipulate the joystick, the use of hydraulic blade will drop from the machine head, so that the tail under pressure; then manipulate dozer lever, so Hydraulic lifting the blade, so that the nose dropped, the tail is reset (depending on the trap car space above process can be repeated operating conditions), and then hang backwards Ⅰ block bulldozers, appropriately increase the throttle, clutch master gear together, so bulldozers backwards a short distance (usually every rewind 5-10cm), then quickly separated from the main brake pedal and clutch lever. Repeated so many times, you can successfully be stuck out backwards Crawler tractor dozer.
(2) If the above method can not be trapped bulldozer out backwards when available rope is fixed at one end to a tree or post, the other end of the rope is fixed on one or both sides of the bulldozer caterpillar (if Only one side tracked stuck, you are stuck on a fixed rope crawler; if both sides are tracked and trapped in deep, then use two ropes fixed on both sides of the crawler), and then start the engine, hang backwards Ⅰ file (or a forward gear Ⅰ), slowly rotating tracks, make rope roll out of the track on top of the bulldozer.

How to distinguish the authenticity of bulldozer accessories
Quality is the basic guarantee bulldozer parts construction equipment to work, but because of the needs and interests of the maintenance of mechanical drive, making the emergence of a wide range of varying quality on the market, imports of construction machinery parts.
Currently on the market, imports of construction machinery parts (bulldozer parts) including whole plant pure components, professional supporting factory quality components, coupled with exquisite genuine parts packaging, but it is from South Korea and China's Hong Kong, Taiwan and other Asian countries and regions transport imports of non-indigenous whole plant parts, as well as some domestic factories and even private informal workshop imitation accessories, but India has imported genuine parts or specialty packaging plant, posing as genuine parts imported for sale. These accessories are collectively referred to as fake, although you can use, but far less than the original genuine parts quality requirements, particularly in the informal manufacturers of generic parts, from materials, technology, function, and so can not achieve genuine parts and specialty plant products quality requirements for normal use and maintenance of machinery and vehicles are affected, and therefore on the operation and use of units of imported machinery parts identification is essential. Imports of machinery parts can be identified in many ways, mainly from the packaging, the intrinsic quality, price and purchase channels to identify. According to the packaging to identify packaging identification is an important program checks the authenticity of imported parts. Genuine parts and accessories for foreign professional supporting factory packaged beautifully, color, pattern, style has certain rules, in general it is difficult to imitate the same. Rough imitation of packaging production, it was easier to identify. But some imitators rely on modern advanced printing technology, packaging production parts very realistic, if not carefully identify difficult to distinguish. Imports of machinery parts generally have outer and inner packaging, packaging has crates, boxes; packaging and plastic bags or wrapping paper is usually identified with paper bags. Pure imported parts outside the box (box) are posted on the manufacturers unified, clear printing, fine paper, and printed with GENUINEPARTS (pure components) mark, and marked with part number, name, number and manufacturer and country. The generic label printing is not fine, the color is not a light weight, consistent with the pure components is hard packed, non-light colors to use the computer to print the part number and manufacturer marks that heavy, carefully identified, will be able to distinguish the authenticity.
