Performance and Usage of Bulldozers

 Bulldozers in China started to be produced only after the founding of New China in 1949. Initially, people added bulldozers to agricultural tractors to make simple bulldozers. With the development of national economy and market, the demand for medium and large crawler bulldozers in large mines, water conservancy, power stations and transportation sectors has been increasing.


Performance of bulldozers

Bulldozers are equipped with bulldozing shovels, mainly for cutting or short-distance handling of earth and rock or bulk materials, according to the engine power to determine its production capacity, bulldozers for road construction are divided into medium-sized (59 ~ l03kw), large (118-235kW) and very large (greater than 235kW) 3 kinds. Bulldozers are generally suitable for the construction environment with strong seasonality, concentrated work volume and poor construction conditions.

Commonly used bulldozers

(1) Crawler type: This type of bulldozer has the advantages of large traction and strong climbing ability, and is capable of handling the more treacherous working environment, and is the representative type of bulldozer, which is widely used in various earthmoving projects.

(2) tire type: this type of bulldozer has the advantages of high driving speed, short operation cycle time, transport transfer without damaging the road, good mobility, etc., and is suitable for municipal projects.

(3) special type: such bulldozers are suitable for specific work situations, such as wetland bulldozers, amphibious bulldozers, underwater bulldozers, demolition bulldozers, cabin bulldozers, military fast bulldozers, etc.


The use of bulldozers

Bulldozer is the tractor as the driving machine, plus the cutting blade of the bulldozer composed of machinery; used to remove land, road structures or similar work.

The bulldozer is an engineering vehicle with a large metal bulldozer in the front, which is used to shovel and push mud, sand and stones forward, and the position and angle of the bulldozer can be adjusted. The bulldozer can complete the work of digging, transporting and unloading soil alone, with the characteristics of flexible operation, convenient rotation, small working surface required, fast driving speed and so on. It is mainly used for shallow excavation and short transportation of one to three types of soil, such as site cleaning or leveling, excavation of pits with little depth and backfill, pushing and building roadbeds with little height, etc.

Bulldozer is also a kind of short-distance self-propelled shoveling and transportation machinery, mainly used for short-distance construction work from 50 to 100 meters. Bulldozer is mainly used to excavate road rift, construct embankment, backfill pits, shovel obstacles, snow removal, site leveling, etc. It can also be used to complete the shoveling and stacking of loose materials within a short distance. When the self-propelled scraper traction is not enough, the bulldozer can also be used to help shovel machine, with the bulldozer plate for top pushing operations. The bulldozer can also use the hook to pull various towed machines (such as towed scrapers, towed vibratory rollers, etc.) for operation.

Conclusion

The bulldozer has a wide range of uses and is one of the most commonly used operating machines in shoveling and transportation machinery, occupying a very important position in earthwork construction machinery. Bulldozers play a great role in the construction of highways, railroads, airports, ports and other transportation, and in the construction of mining, agricultural land renovation, water conservancy construction, large power stations and national defense construction.

Reasonable Operation Of Track Bulldozer

图片
The  Track Bulldozer   has the greatest influence on the transmission oil temperature due to the external resistance and the maximum output torque during the shovel operation. If the small throttle is used for a long time to operate the torque converter in the inefficient zone, the transmission oil temperature will rise. If the large throttle is used during frequent shifting, it will cause severe impact on the machine and increase the temperature of the transmission oil. To this end, the operator should reasonably control the amount of bulldozer and the timing of the blade lifting and lowering. The soil feeding distance should not be too long, so as to prevent the use of small throttle for a long time. We are  Track Bulldozer Supplier , specializing in the production of machinery and equipment, welcome to consult and order.

No Steering Failure of Crawler Hydraulic Steering Bulldozer

图片
  During the use of the bulldozer, due to various reasons, the bulldozer is difficult to turn, cannot turn, cold cars can turn, hot cars can not turn. After the occurrence of these failure phenomena, according to the use time of the bulldozer and the occurrence process of the failure, the classification analysis should be carried out to check the truth, which can avoid unnecessary disassembly and reduce the internal pollution of the machine. The following   Bulldozer Suppliers   introduce common fault phenomena such as bulldozers and related knowledge of inspection and elimination. When the  Dozer  is in use, it suddenly fails to turn on both sides. The overflow valve at the oil inlet of the directional control valve assembly can be disassembled. The reason is that the oil is too dirty, the impurities in the oil wear or strain the surface of the overflow valve core and the inner cavity of the valve body, so that the valve core is stuck in the position where the oil return is turned on,
