  Due to the influence of materials, craftsmanship and human factors, various failures will inevitably occur when using   Bulldozers . However, if you can correctly analyze the causes of various failures and take effective preventive measures, you can extend the service life of the machine. 1. Reduce the impact of mechanical impurities Mechanical impurities usually refer to non-metallic substances, such as dust and soil, as well as some metal shavings and wear products produced by the construction machinery itself during use, especially  Low Cost Bulldozer . Once these impurities enter the machine and reach the mating surface of the machine , The danger is great, Bulldozers 2. Reduce the influence of temperature In operation, the temperature of each component has its own normal range. Lower or higher than this range will accelerate the wear of parts, cause lubricant deterioration, and cause changes in material properties. In the process of using construction machinery, first of all, it

  During the construction of   Track Excavator , rollover is one of the most common accidents. Due to the light and narrow body of the excavator, it is more prone to rollover than a large excavator. How to avoid the side when the excavator is constructed? There are three main points: First, Due to the off-road nature of the Excavator, the excavator can climb steep slopes by rail and work equipment. It can also easily descend downhill. Everyone can easily ignore the dangerous situation. When the mini excavator goes downhill or along the trailer At this time, many drivers will push the front windshield or door frame with their left hand and push the excavator with their right hand. At this time, if the door is open instead of locked, the door will close quickly due to gravity, which is usually Great strength. The handheld on the door frame will be caught. Very serious consequences. Therefore, when the  Wheel Excavator  is working, there is a lock on the door of the excavator. When it is

  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,

  First, the ability of the   Construction Machinery Crawler Dozer   and the unloaded vehicle and the associated load-bearing capacity can be required for the excavator's production capacity. It should be noted that the capacity of the carrier should be an integer of the bucket capacity. In the operation, we can use the double-displacement method, and after loading one car, we can continue to load the next one, which can save a lot of time and overall work efficiency. The docking of the loading vehicle is also available, for example, it is stopped on the circular arc that the excavator's bucket can unload so that the  Engineering Construction Bulldozer  can load the material during the second rotation. Bulldozer Second, the layout of the job site can also be very efficient. For example, before the construction, it is necessary to draw some driving routes for the loading vehicle, some uphill roads, etc., which can be staggered in advance to save driving time. The dump trucks do

  1. Variable speed and forward and backward When shifting into gear, first push the throttle handle forward to the low-speed idling position, and then push the main clutch lever to the forefront to separate the main clutch. Due to the action of the small brake in the main clutch, the power input shaft of the transmission stops rotating . At this time, you can correctly move the shift lever to the required gear, and then put the forward or backward lever to the forward or backward position. After the gear is engaged, pull the throttle handle backward to increase the engine speed, and connect the main clutch smoothly, and the bulldozer starts to drive. When the bulldozer is driving, the main clutch control lever should be pulled to the rearmost position, not in the half-engaged position. Because the half-engagement of the main clutch will aggravate the friction lining wear. The  Crawler-Type Bulldozer  transmission generally has 5 forward gears and 4 reverse gears. The advance and retre
