Maintenance of hydraulic excavator hydraulic excavator swing member located undercarriage upper revolving platform on the body, as the body's head and torso camel important. Although the structure is difficult to see from the outside, but the installation in which the engine and various hydraulic equipment defects or overload, it will affect the overall state of the machine, so that the performance decline, resulting in machine failure. Therefore, routine maintenance checks should be upper revolving platform machine in the first place. So now the question is, in order to improve the operating performance of the upper rotating platform and to prevent unnecessary loss fault occurs in the upper revolving platform maintenance should pay attention to what areas? Regularly check and replace the filter cartridge in order to prevent dust and inserted The main parts of the intrusion of the machine oil and other impurities contained in the excavator has taken protective measures. On an excavator mounted multiple filters, these filters play an important role in their respective. Taian Jia and Heavy Machinery Co., Ltd.
