  Today   Crawler Dozer Supplier   introduces the repair and maintenance of bulldozers. 1. Inspection and maintenance Whether the high-pressure pipe joints, oil cylinders, floating oil seals, radiator fins, and water pipe joints are leaked, if any, should be eliminated in time. Whether the electrical system is disconnected, short-circuited, and whether the terminals are loose, if there is, it should be eliminated in time. Inspection of engine oil sump: When the engine is stopped, first determine the engine oil pressure gauge and whether the water temperature gauge is in the normal range, and then take out the dipstick to check that the liquid level should be between the upper and lower marks of the dipstick. If you need to add oil, open the oil filling port and add it. When checking the oil level, park the vehicle on a level surface. When adding oil, do not raise the oil level above the "H" mark.   2. Check the oil quantity of the rear axle box: (1) Inspection and maintenance

  Today   Dozer China Factory  will introduce the knowledge of bulldozers in detail. Bulldozer is an earthmoving engineering machine capable of excavating, transporting and abandoning rock and soil. It is widely used in open-pit mines. For example, it is used for the construction of dumping grounds, leveling of automotive dumping grounds, accumulation of scattered ore rocks, leveling work flat plates and construction sites. It is used not only for auxiliary work, but also for main mining work. For example: stripping and mining of sand deposits, traction and boosting of scrapers and plows, and other earthmoving machinery to reduce the stripping step height when there is no transportation mining method.   Classification of bulldozers: 1. Divided by walking method Bulldozers can be divided into  Crawler Dozer  and tire type. Tracked bulldozers have large traction, low ground pressure (0.04 to 0.13 MPa), strong climbing ability, but low driving speed. Tired bulldozers have high driving spe

The proper use of  Bulldozer  is an effective way to improve ergonomics. It can be seen from the calculation formula of the bulldozer's production string that all parameters except the shovel are variable. The factors affecting these variables are artificial and objective factors. It is mainly to resolve the influence of human factors, which is related to the construction method, construction organization and operation skills. Bulldozer When the bulldozer pushes the soil, the soil is lost more, and it is related to the transportation distance and the construction method. Reducing soil loss and increasing the load factor are one of the important measures to improve the utilization rate of the bulldozer. Keep the economic distance of the bulldozer (30-45M), and choose the best construction method according to local conditions. It is an effective way to improve the load factor. The following  Bulldozer China Factory  introduces several common construction methods: (1)

Today  Wheel Excavator China Supplier  will introduce the method of correct maintenance of the bulldozer. Crawler Dozer (1) Maintain proper tension of the track For the  Crawler Dozer , if the tension is excessive, the spring tension of the guide wheel will act on the track pins and pin sleeves. The elastic force of the wheel tension spring also acts on the guide wheel shaft and the sleeve, which generates a large surface contact stress, which makes the guide wheel shaft sleeve easy to be ground into a semicircle, the track pitch is easily stretched, and the mechanical transmission efficiency is reduced, and the engine is wasted Power transmitted to drive wheels and tracks. If the track is tightened too loosely, the track is easily detached from the guide wheels and track rollers, and the track loses the correct centering, causing the running track to fluctuate, flap, and impact, causing abnormal wear of the guide wheels and idlers. The adjustment of the track tensio

Excavator is a fixed asset with large economic investment. In order to increase its service life and obtain greater economic benefits, the equipment must be assigned to people, machines and positions, and responsibilities must be clear. The driver should pay attention to these when driving the excavator: After the excavator enters the construction site, the driver should first observe the geology of the working face and the surrounding environment. There must be no obstacles within the radius of the excavator's rotation to avoid scratching or damaging the vehicle. After the machine is started, no one is allowed to stand in the bucket, on the shovel arm and on the track to ensure safe production. When the excavator is shifted, the driver should observe and whistle first, then shift to avoid safety accidents caused by people on the machine side. The position after shifting should ensure that there is no obstacle to the space of the excavator's rotation radius, and illega

With the continuous improvement of the degree of mechanization, the use of agriculture bulldozer is generally used in rural land reclamation and development sites. The safety of  Agriculture Bulldozer   should pay attention to the following points: TY165-3 Bulldozer ①Dozing work cannot be carried out in dangerous places. It is not allowed to pass through mud ditch and dam to prevent trapping. The slope can be operated at a place with a slope greater than 20 degrees. ②The dozing work should be based on the soil condition and choose the appropriate speed to prevent overloading. When transporting the soil, place the dispenser handle in a floating position to lift the blade freely. ③Do not turn during the shoveling and earth moving, otherwise the steering clutch and other parts are easily damaged. Try not to raise or lower the piston in the cylinder to the limit position. ④After cutting the blade into the soil, adjust the amount of soil at any time according to the sou
