As a heavy construction machinery, Liugong loader has a wide range of applications in construction, mining, ports and other fields. However, as the service life increases, the loader will also experience problems such as wear and corrosion, resulting in reduced performance and even inability to use normally. First of all, it should be clear that the service life of Liugong loaders is affected by a variety of factors, such as the use environment, work intensity, maintenance, etc. Therefore, it is difficult to give a specific scrapping age. Generally speaking, if the loader has severe wear and corrosion during use, or the technical performance cannot meet the requirements of the job, the issue of scrapping needs to be considered. In actual use, many enterprises and individuals will decide whether to scrap or not according to the use and efficiency of the loader. Some older loaders may be obsolete due to high maintenance costs and low efficiency, while some well-maintained and stable loaders can last longer. In short, for the scrapping of Liugong loaders, a comprehensive assessment needs to be carried out according to the actual situation. When choosing whether to scrap or not, multiple factors such as the age of the loader, maintenance costs, and technical performance should be considered to make the most reasonable decision. In addition, regular maintenance is also very important for the Liugong loader in use. Reasonable maintenance can prolong the service life of the loader, improve work efficiency, and create more value for the enterprise.
