Choosing a  bulldozer with reliable quality  is very important for engineering construction and will directly affect the efficiency of the machine, the progress of the project and the benefits of the user. 1. Determining the power level of the machine. When Determining the bulldozer to which a large power grade is purchased, the user should select it based on the size of the project and the reasonable applicable range of the power grade of the bulldozer. For the selection of the power level of the machine, it is necessary to comprehensively consider the factors such as the soil quality of the project and the nature of the machine operation. For example, the machine should be constructed under the soil environment mainly composed of sand and rock. Generally, the bulldozer of 162kw (220 horsepower) or more should be selected; if the bulldozer in addition to the shovel operation, the pulling operation is frequently performed, which requires consideration of the traction of the machin

For the wear of the crawler type walking mechanism, the following measures should be taken: 1. If the  bulldozer with reliable quality  running mechanism has obvious wear at an early stage, stop the operation immediately and check the coincidence degree between the guide wheel, the sprocket wheel, the roller, the drive wheel center and the longitudinal centerline of the walking frame; 2. In order to extend the service life, the front and rear rollers can be exchanged for the position, but the original position of the single and double-sided rollers on the walking frame must be kept unchanged; 3. After the components of the traveling mechanism are worn to the limit of use, the guide wheels, the sprocket wheel, the roller, the drive wheel teeth, the spurs, and the chain link may be repaired or replaced by surfacing; 4. In the case where the track link pitch lengthens due to wear, the reverse link section can be used to remedy or replace the new link section. We are  bulldozer

What is hydrostatic? The  hydrostatic bulldozer  is also called a full hydraulic bulldozer, which means that the bulldozer uses hydrostatic transmission technology. The hydrostatic transmission is the direct transmission of power with hydraulic oil. Its main components are the hydraulic pump, control device and hydraulic motor. The advantages of the hydrostatic drive are large transmission ratio, high transmission efficiency, stepless speed regulation, etc. Hydrostatic drive is regarded as the mainstream development direction of future bulldozers. In addition to hydrostatic transmission, the bulldozer also has mechanical transmission, hydraulic transmission, electro-hydraulic transmission and other transmission methods. The power transmission route of the mechanical transmission is: engine - gearbox - drive shaft - drive axle, which is difficult to achieve stepless speed change, and the shock resistance is relatively poor. The hydraulic transmission uses the kinetic energy of li

Do you know that there are fuel-efficient operating techniques when operating the  high efficient bulldozer , let's take a look at these tips. Today, as oil prices continue to soar, the major oil-consuming engineers of construction machinery can consume real money every day. How to consume the least amount of oil to dry the most is a big concern for users. In fact, fuel economy and work efficiency do not conflict, the key is the details, develop good habits in the actual work, reduce fuel consumption, improve work efficiency is a very simple thing. Grooved bulldozing method In the actual process, the groove type bulldozing method can be applied: the optimal working distance of the bulldozer is 50 meters. If the distance is too long, the material pushed by the bulldozer will be scattered. In this case, the principle of the groove can be utilized to make the material more concentrated. When the  easy maintenance bulldozer  is working, it will first push a groove out, then

1. Turn When the  crawler dozer  is turning in operation, the steering clutch lever can be pulled back to separate the steering clutch, so that the track speed of the corresponding side becomes slow, and the bulldozer starts to turn. In order to make the bulldozer turn sharply, in addition to separating the steering clutch, the corresponding brake pedal should be stepped on, and the sharp turn is generally allowed only when the Ⅰ gear is running. When the brake is not in use, the foot should not be placed on the brake pedal, otherwise, the brake band wear and fuel consumption will increase. When the bulldozer is turning, the brake pedal should be smoothly pressed to avoid jumping. After the turn is over, loosen the brake pedal and then release the joystick. If the turning radius is large, it is not necessary to step on the brake pedal. When it is not necessary, it is forbidden to make the bulldozer rotate at high speed in order to avoid accidents caused by track derailment. 2. R
