What should be paid attention to when buying a used excavator? The factory date and working time are only part of it.

　　There are many concerns and considerations when we choose a Tiedou used excavator. In addition to the brand we like, we also have our own requirements for the appearance and performance of the excavator. Of course, the price of the used excavator is also our focus. Here TD teaches you what to pay attention to when choosing a used excavator. Appearance and wear and tear condition, many users need us to provide a large number of detailed pictures and display videos of the excavator to initially understand the general situation of the used excavator, and judge the basic status of the equipment by observing the details of the excavator, but this is only a small part, and the focus is on showing the performance of the excavator through video testing.

　　Understand the excavator's factory date and working time to judge the excavator's value. Although the factory date is important, it is not the most critical. Most excavator equipment has a short working time. The working environment is good, and even some used excavators that are about 10 years old still have excellent performance. The shorter the working time, the higher the price. 3000-8000 is a very good choice.

　　The working environment and the type of work directly affect the wear and performance of the excavator. In the last TD, we talked about the damage of installing hydraulic crushing to the excavator, so we recommend that you choose an excavator without accessories installed. If the excavator has a maintenance manual, then we highly recommend this excavator. Excavator equipment maintained by a dedicated person is still very trustworthy. The following three items are only the basic conditions for purchasing a used excavator. You need to know more details about the used excavator before purchasing.

　　1. Excavator Year - Best Year Range: Generally speaking, it is more appropriate to buy a second-hand excavator that has been manufactured within 3-5 years. These equipment are usually newer in technology and have not been used for a long time. - Equipment Update Cycle: Most manufacturers will update their equipment regularly, which means that buying a second-hand excavator of a newer year can get relatively advanced technology and design.

　　2. Working Time - Ideal Working Time Range: The working time of a second-hand excavator is generally between 3000-5000 hours. Equipment within this range usually has less wear and tear and still has a longer service life. - Maximum working time: Excavators with more than 8.000 hours of operation usually experience more wear and tear and breakdowns. Be cautious when purchasing, and they may require more repairs and maintenance.

　　3. Working environment - High-quality working environment: It is best to choose an excavator used in a dry and dusty environment. Such equipment usually has less wear and tear and is better maintained. - For example: construction sites and urban construction environments are usually better. - Avoid harsh environments: Avoid buying excavators that have worked for a long time in harsh environments such as mud, mines or saline-alkali land. These environments are prone to corrosion and accelerated wear of equipment.

　　If conditions permit, we should try to choose well-known and well-reputed excavator brands and models when purchasing used excavators. Especially some classic models, although they are a little older, they have been tested by the market and are very reliable.
