Crawler bulldozer is an important earth-rock engineering machinery. We often see it on construction sites and road construction sites, but its uses are far more than that. Others such as mining, water conservancy, agriculture and forestry, etc. are involved in excavation, Crawler bulldozers are indispensable for accumulation, backfilling and leveling operations. The more complex the working environment, the more obvious the advantages of crawler equipment, but its own models are also subdivided to better adapt to different working conditions. Next, Hongkai Xiaobian will introduce the classification and purchase methods of crawler bulldozers.
1. Classification of crawler bulldozers
(1)Classified according to engine power
At present, the power of crawler bulldozers sold in my country’s market mainly includes 95kW (130 horsepower), 102KW (140 horsepower), 118kW (160 horsepower), 169kW (220/230 horsepower), and 235kW (320 horsepower). It operates under various working conditions, among which 118kW (160 horsepower) is the mainstream product.
(2)Classified according to applicable working conditions
According to the specific applicable working conditions, crawler bulldozers can be divided into two general types, dry land type and wet land type. ), ultra-wet land type (lower grounding specific pressure), sanitation type (for environmental protection) and other varieties.
(3) Classified according to transmission mode
The transmission methods of crawler bulldozers are mainly divided into two types: mechanical transmission and hydraulic transmission, and their power transmission routes are different. Mechanical transmission: engine→main clutch→mechanical gearbox→middle. Central transmission → final deceleration → crawler walking system; hydraulic transmission: engine → hydraulic torque converter → power shift gearbox → medium. Central transmission → final deceleration → crawler walking system.
2. How to choose and buy crawler bulldozers
(1) Determine the type of bulldozer
According to the soil conditions of the construction site, determine whether to choose a dry land type bulldozer or a wet land type bulldozer, and then select the type of working device and attachment type of the bulldozer according to the specific operation object.
(2) Determine engine power
The engine power of crawler bulldozers should be selected according to the size of the project, the actual working conditions on site and other factors, such as general engineering construction, highway construction, infrastructure construction, etc., can choose 95kW (130 horsepower), 102KW (140 horsepower) 118kW (160 horsepower) , 169kW (220/230 horsepower), 235kW (320 horsepower) bulldozers; large-scale water conservancy, mining and other projects can choose 235kW (320 horsepower) or more bulldozers.
