How many years can an excavator last? The service life of second-hand excavators is determined by

There is a question that many people in Huacheng will ask, which is how long can excavators last? The focus here is on the actual service life and working time of excavators. In theory, the service life of excavators exceedsOver the course of 15 years, the longer the equipment is used due to mechanical wear and internal structural looseness, the more severe the failure rate becomes. With proper and careful maintenance as a prerequisite, the construction life will exceed 20 years when faults are properly handled. But in domestic equipment, there are rarely any excavators that can be used for longer periods of time. Some old excavator equipment in China, such as the Hitachi EX-2 series, Komatsu PC-5 series, and CAT CAT B series, can still work normally after more than 20 years of use. The main reason lies in the inseparable relationship between good equipment performance and long-lasting durability.

There are many factors that can shorten the service life of second-hand excavator equipment, aside from accidents and human injuries. The construction environment has the highest proportion, and the reason why old equipment is rarely seen in the north is mainly due to the harsh winter climate and frozen soil. The power loss of old equipment is difficult to adapt to, and the elimination rate is extremely high. The service life during the replacement cycle is much shorter than in the south. The temperature and excavation conditions in the south are better than those in the north of China. In addition, the developed supply chain of southern accessories can solve problems in a timely and proper manner. The fundamental reason why the number of old equipment in the south is far greater than that in the north under various construction conditions.

The best year for comprehensive analysis of excavators (excluding inferior equipment and difficult construction sites) is five years, during which excavators have strong power control and extremely low failure rates.5-10 years is the biggest watershed for device transactions, and this year has a large number of device transactions. The buying and selling transactions are most active when the performance loss is not significant and the appearance is maintained well. Recommended models for cost-effectiveness in the 10-15 year period, undertaking projects with harsh environments and arduous work. 15-10 years belong to“Vintage car”Stage. This year is not without good opportunities, but if the proportion is too small and the risk is too high, except for special engineering needs and professional selection of Huacheng, it is not recommended for everyone to consider more equipment for this year. andEquipment over 20 years old can be said to“only one in a hundred is chosen”The situation of machine damage and aging is extremely severe. It can only be used as a short-term engineering project and cannot withstand long-term use with a high failure rate. It is difficult to purchase and maintain obsolete equipment parts. Even minor issues that require major repairs are normal.
