We have introduced a lot of knowledge about bulldozers in our previous articles, such as how to use them, how to select them, the internal structure of bulldozers and so on. Today   dozer supplier HBXG   introduces the correct maintenance method of bulldozers, hope it will be helpful for you. Track tension For crawler bulldozers, if the tension is too high, the spring tension of the guide wheel will act on the track pin and pin bushing. The elasticity of the wheel tension spring also acts on the guide wheel shaft and bushing, generating a large surface contact stress, making the guide wheel bushing easy to grind into a semicircle and the wheelbase easy to elongate, reducing the mechanical transmission efficiency and wasting the mechanical transmission efficiency. The adjustment of the track tensioning force is carried out by filling or releasing grease from the oiling nozzle of the tensioning cylinder, referring to the standard clearance of each model. Appropriate treatment, such as pi

Bulldozers are heavy equipment and buying one means an equally huge investment. Like any other huge investment, there are many things that should be considered before making a final decision. Unfortunately, most people don't know what to look for when buying a bulldozer and they end up looking only at the price. While the cost involved is a huge factor that must be considered, buying a dozer is more than just haggling with a dealer to get a great deal. Here are a few things you must consider before you buy a dozer. Landing gear Depending on the terrain and environment in which you plan to use the dozer, you must not forget to check the landing gear of the dozer you choose to buy. Chassis systems primarily include standard and heavy-duty. Heavy-duty landing gear has similar features to standard landing gear, but has enhanced components, such as steel plates, that are incredibly strong. If you are going to use your dozer in rough terrain and rocky conditions, you should get a heavy-

If you want to know how to grade with a bulldozer , you must learn from experience. Knowing what the correct load in the blade feels like is how operators have graded with dozers in the past. While this process works well for those with years of experience, new operators often make mistakes when trying to grade the ground without help. By integrating slope control technology into the dozer, even new operators can successfully grade terrain without years of experience. 1. Improved Accuracy While using manual controls for grade, feel for soil and focus on finish works well for some jobs, grade control using GPS can significantly improve accuracy. Achieving such accuracy throughout a project can be difficult without technical assistance. Experienced veterans using bulldozers can also improve their grading accuracy and efficiency. By allowing any operator to perform quality grading, a grade control system can help contractors make the most of the existing personnel on their team. New emplo

Effectively spreading material with a   bulldozer  can reduce the amount of time needed to complete a construction project. By using these tips and the right tools below, you can learn to properly and efficiently grade land and save time on construction projects that require grading or spreading materials. SD7K Bulldozer Historical Use Bulldozers use blades to move dirt, which helps grade land for roads or construction sites. bulldozers were first used by railroad companies in the late 1800s to grade railroad lines. These early bulldozers got their name from the pair of bulls that provided the power. Tracked vehicles came into use to replace the pack animals that drove the tractors. It wasn't until 1921 that tractors with blades were fitted with these tracks. This early 20th century innovation paved the way for future bulldozer upgrades by attaching motors and tracks to previous versions of bulldozers. By 1928, bulldozers were upgraded with cables and winches that allowed the shove

Routine maintenance is a very important task. Doing a good job can not only make the   bulldozer  run safely, but also extend its service life. Therefore, bulldozers should be inspected and maintained as required before and after operation. hbxg introduces them for you. Maintenance of track The adjustment of track tension is done by adding grease to the nozzle of the tension cylinder or discharging grease from the outlet nozzle, referring to the standard clearance of each model. When the track pitch is stretched to the point that a set of track sections needs to be removed, the engagement surface of the drive wheel teeth and the pin sleeve will also show abnormal wear. In this case, the crawler bulldozer maintenance method should be handled properly before the engagement condition deteriorates and the crawler is maintained. Type bulldozer methods such as turning over pins and pin bushings, replacing excessively worn pins and pin bushings, and replacing track section assemblies. Daily i
