After the reform and opening up, with the development of the national economy and the market, large-scale infrastructure projects such as large mines, water conservancy, power stations, and transportation have continued to increase, and the demand for medium and large crawler bulldozers has also increased. At the same time, it has also given birth to the continuous growth and development of some large bulldozer manufacturers. Common domestic brands include Shantui, Xuangong, Yishan, Dadi, Zoomlion, Dongfanghong, etc. Let’s talk about the performance and Features.

　　One, bulldozer classification

　　The front of the bulldozer is equipped with a bulldozer blade, which is mainly used for cutting or short-distance transportation of earth, stone or bulk materials. The production capacity is determined according to the engine power. The bulldozers used for road construction are divided into medium-sized (59～l03kw) and large (118- 235kW) and extra large (greater than 235kW) 3 types.

　　2. Three types of commonly used bulldozers

　　1: Crawler type: This type of bulldozer has the advantages of large adhesion and traction, strong climbing ability, and can be competent in more dangerous working environments. It is a representative model of bulldozer and is widely used in various earthwork projects;

　　2: Tyre type: This type of bulldozer has the advantages of high driving speed, short operation cycle time, no damage to the road surface during transportation and good mobility, etc., which is suitable for municipal engineering;

　　3: Dedicated type: This type of bulldozer is suitable for specific working conditions, such as wetland bulldozers, amphibious bulldozers, underwater bulldozers, blasting bulldozers, cabin bulldozers, military fast bulldozers, etc.

　　Three, the use of bulldozer

　　1: Short-distance earth and stone transportation

　　2: Shovel and move the soil

　　3: Leveling the ground

　　4: Mining and stripping of deposits

　　5: Clear roadblocks, etc.

　　The use of bulldozers is very wide, and it occupies a very important position in earthmoving machinery. Bulldozers play an irreplaceable role in the construction of roads, railways, airports, ports and other transportation, mining, farmland reconstruction, water conservancy construction, large-scale power stations and national defense construction.
