10 key points for evaluating the value retention rate and price reference of second-hand excavator equipment (2)

　　Today, we will continue to introduce the reference opinions on the value retention rate of second-hand excavator equipment. The previous issue introduced the reference of 5 brands, time, maintenance, status and chassis and other components. What other aspects can be compared for the value retention rate or second-hand price of second-hand equipment?

　　6. Appearance and status

　　For most people who buy used excavators, they observe the appearance or the visible area to observe the use of the equipment. Of course, this is a very direct and very effective selection method, but it is not the best method. The different working environments of excavator equipment are very common for the appearance to be worn and bumped. Users can judge the use environment of the excavator by observing the appearance, but there are some equipment that need to be repainted, which users cannot observe with their naked eyes. Bumps can also be corrected by sheet metal later, but the appearance does not have much impact on the price of the excavator. However, if the equipment is corrected later, the value retention rate is slightly lower than the value of the original equipment.

　　7. Excavator testing and performance testing

　　This is also the most important part of buying used equipment. This is not just for construction machinery purchases. Excavator testing is divided into many parts. In addition to the operator's test of the smoothness of the action connection between the excavator boom, dipper, and bucket, the excavator's walking, slewing system, engine power, hydraulic pump flow, operating temperature, air conditioning, and electronic control system all need to be carefully tested. In particular, it is necessary to test in a suitable working environment to maximize the test results to the effect you need. During the test, the excavator load test, especially when the bucket is carrying heavy objects, whether the work between the dipper and the boom is smooth, the load has high performance requirements between the engine and the hydraulic pump, which can greatly reflect whether the new energy standard of the core assembly meets the use requirements. If there are no conditions, the throttle modulation can be minimized, and the equipment can be propped up by supporting the boom, dipper, and bucket to check whether the engine and hydraulic pump have abnormal sounds, and whether there is pressure relief under high pressure. Problems can be completed through such tests. There are many ways to test the excavator. In addition to consulting professional operators, you can also check the information to understand the equipment testing standards.

　　8. Fuel economy and environmental protection requirements

　　For developed countries, environmental protection is a very important standard. Every few years, each country will have new environmental protection requirements. This also means that the higher the environmental protection level, the closer the equipment is to the year. The fuel economy is higher in the current new excavator equipment. The engine has higher fuel efficiency. Each manufacturer has its own requirements and standards.

　　9. Configuration and accessories

　　When purchasing used equipment, especially excavators, different types of accessories can be installed. Here, users need to understand that the price of some accessories is even higher than the excavator itself. However, this type of accessories is more targeted, but common accessories such as hydraulic crushing, eagle beak pliers, wood clamps, etc. are cheap and have a wide range of applications. If you need this kind of work in the future, you can install the accessories required in advance to facilitate later replacement.

　　10. Market and environment

　　The same brand and model have certain price errors in different countries. This is the market demand and environmental demand. Why do we choose Tiedou used excavator trading network when we buy used excavator equipment? It is mainly because China has a huge user group and manufacturing group of engineering machinery. The world-renowned engineering machinery manufacturers basically have production bases in China. In particular, the number of excavators in China is large, which also means that the reserve of second-hand equipment is large, the competition is fierce, and the price is relatively cheap. This is one of the important reasons why Chinese excavators are cheaper than many other prices.
