How to distinguish the authenticity of second-hand excavators with sharp eyes!

In China, second-hand excavators are flooded with a large number of renovations, assemblies, modifications, and even brand and model changes. This is not only for businesses, but also for individual machine owners during construction. The situation of changing models and schedules is not uncommon, and such situations seem to have entered a behavior that everyone considers to be normal. Buying excavator equipment has become not only the only way to test eyesight and experience, but even luck has become a method. There are many customers who are lucky enough to buy a machine that can work and have fun, but if they are unlucky enough to buy a machine with many faults, they should spend a lot of money to repair it. If it cannot be repaired, they should sell it as soon as possible.

For many novices and even experts in this industry“Water depth”The lack of clear regulation and legal constraints in the trading process in major industries has led to various negative situations repeatedly occurring. How to develop a pair of sharp eyes during the trading process has become an essential compulsory course for us. Is the second-hand excavator market all bad? Of course, this does not necessarily mean that there will be problems in the sales market of large-scale construction machinery in China. Similarly, it depends on how we choose equipment with high cost-effectiveness and good condition. Nowadays, various brands and models are updated and replaced every year, so it is impossible for everyone to have a deep understanding of all machinery. Here, Huacheng mainly explains what to pay attention to when buying a second-hand excavator.

Firstly, personal testing is necessary for second-hand equipment to undergo rigorous on-site testing. In the early stages of testing, our understanding of the equipment may not be deep enough, so we need to extend the testing time. If we are optimistic about a mechanical device, we need to further deepen the testing of important coordination combinations such as the engine hydraulic system and distribution valves in terms of time and workload. Eliminate problems such as high temperature, engine holding, oil burning, uncoordinated movements, and weak rotation during walking one by one.

Secondly, do not pay too much attention to the factory annual fee and usage time. In the second-hand construction machinery industry, the usage time is extremely inaccurate. If it is necessary to check, professional testing equipment needs to be taken out for inspection, which is unlikely to be achieved for a large number of purchasing consumers. So we need to check the wear and tear of each component to identify the approximate year, mainly observing the overall wear and tear of the equipmentIs the wear and tear on the surrounding area of the X frame severe, and has the oil circuit and oil cylinder been replaced? If the pipeline has not been replaced by the original factory and the oil seal of the oil cylinder is also original, it can be recognized that the equipment has been in use for a very short period of time and years. The same approach is suitable for in-depth and detailed observation in more places. I won't list them one by one here.

Thirdly, there are many ways to check the year, and many equipment's stamped nameplates have serial numbers and production numbers. If you are not familiar with them, you can use Baidu to search. The body nameplate can be modified through loading and unloading, so a thorough inspection of this part must be conducted from the engine and distribution valve parts. Especially behind the air filter cover, the vast majority of manufacturers have clear standard production years and times.

Fourthly, when it comes to paint, many people think this is easy to observe, but many unscrupulous businesses have sophisticated techniques in the later stages of painting, and even some experts may not notice it. Merchants spend a lot of money to make a painted equipment look like a new machine by using original paint, blending it later, and then polishing and aging it. But such equipment vendors tend to use devices with excellent condition and performance, and rarely buy devices that cannot work except for those that may cost money unnecessarily.

Huacheng provides a series of strict testing equipment and methods to ensure the exact year and actual usage time of the purchased excavator. Ensure the legitimate rights and interests of customers. We treat every excavator with the most rigorous attitude to give you peace of mind and peace of mind.
