The main power of the second-hand excavator walking system relies on the hydraulic system to provide hydraulic power to the walking power. The advantage is that the power is strong, especially on muddy roads, there can be sufficient walking power. It should be noted that the heavier the excavator, especially for large excavator equipment weighing 30-40 tons, it is currently impossible to provide such a large power output by relying on electric drive motors. However, it is also very obvious that the hydraulic walking system cannot provide long-term work, and many factors such as temperature limit the possibility of irreversible damage during walking.
Some roads are rugged, and transportation vehicles require equipment to travel for a long time to reach the construction site, so they need to go through necessary shutdown preparation, because the wear of different walking components of the structure is also the most serious part of the entire equipment. The walking drives the driving gear to drive the chain rib chain plate, and the entire component relies on the connection between steel to drive. Long term wear, especially the wear of the driving gear and guide wheel, is the most prominent. It is important to emphasize that daily wear and tear should be checked regularly. If severe wear is found, it must be replaced in a timely manner. If uneven force is applied during use, it can cause deformation and wear to expand, resulting in more connecting gaps between components and irreversible damage.
So why are you hereSecond hand excavator marketIs there an inspection of excavator equipment during walking? If conditions permit, test whether the walking speed on both sides is consistent to determine whether the internal structural power output is uniform, and then check whether there is deviation in walking through parallel walking. If the speed remains constant, check whether there are differences in the wear of structural components. In the setting of walking excavators, there are usually turtle gears and rabbit gears, which can also be divided into high-speed and low-speed gears for testing. Huacheng second-hand excavator market provides up and down slope walking tests, under which the power output of the walking components in reverse can be fully demonstrated.
It is also emphasized here that the walking motor requires regular replacement of the walking motor gear oil, which many customers often overlook here. There is a grease nozzle on the inside of the excavator to provide track shoes“Tight and loose”Adjustment can be made according to the working environment and model. However, during the adjustment process, do not excessively stretch the track shoes, which may cause increased wear. Some equipment may have hanging chains during operation, which cannot be solved by simply adjusting the extension. The main problem is to check the wear of the guide wheels and drive teeth to make a judgment,Second hand excavator pricesMedium wear and tear is an important criterion, and the wear and tear of equipment should be relatively small when the working environment is easy.
