In the field of engineering construction, second-hand excavators have become the choice of many practitioners due to their relatively low prices. However, there are many "pitfalls" in the purchase process that are easy for people to step on.
In terms of equipment condition, appearance illusions are very common in the second-hand excavator market. Unscrupulous merchants often over-refurbish the machines, such as repainting to make the body shell brand new, but the aging and wear of key parts such as the chassis and tracks are covered up. This phenomenon is particularly common in the informal second-hand trading market. However, formal second-hand dealers such as us will conduct a comprehensive and transparent vehicle condition display after purchasing second-hand excavators, not only focusing on the appearance but also detailing the true situation of key parts. Concealing mechanical component failures is also a problem. As the core component, the engine may be covered up by bad merchants through cleaning to cover up the hidden dangers of burning oil or insufficient power. It is difficult to find it in a short test run, but it will be exposed in subsequent high-intensity operations; the sealing of the hydraulic system is crucial to the normal operation of the excavator. Some merchants simply temporarily deal with the leakage points of the hydraulic pipeline instead of completely repairing it, while regular second-hand dealers will conduct professional pressure tests on the hydraulic system to ensure stable operation; the wear of components such as gears and drive shafts in the transmission system is easy to be ignored. Severe wear will lead to poor power transmission and reduce efficiency. Professional second-hand dealers will conduct detailed inspections and assessments of these components and provide test reports.
In terms of documents and materials, the property rights of second-hand excavators cannot be ignored. Some equipment may be in a mortgaged state or even stolen vehicles. In informal trading channels, such unclear property rights often occur. Regular second-hand dealers will ensure that the property rights certificates are clear and legal before the transaction to avoid consumers from falling into legal disputes. They will verify with relevant property registration agencies to ensure that each excavator sold has clear property rights. Maintenance records are also very important. Some sellers cannot provide complete records, making it difficult for buyers to evaluate the true condition of the equipment. Some bad merchants provide forged records, delete important maintenance events or tamper with maintenance time and content. Formal second-hand dealers guarantee the authenticity of records and provide detailed interpretations to help consumers understand the historical maintenance of the equipment.
In terms of the transaction process, price misleading is very common. Some merchants deliberately raise prices and use false discounts to attract buyers. For example, an excavator with a market price of 300,000 yuan is marked at 400,000 yuan and then claimed to give a 100,000 yuan discount to make consumers mistakenly think that they have picked up a bargain. Some merchants use package sales to bundle unnecessary accessories or services to increase consumer costs. Formal second-hand dealers will provide flexible purchase plans based on the actual needs of consumers and will not force package sales. Unprofessional testing can also cause problems. If buyers do not conduct professional testing or rely on non-professionals, they may ignore many potential problems. Problems that affect safety and reliability, such as aging of electrical system lines and short circuits, may be ignored. Formal second-hand dealers usually have professional testing teams and use professional testing equipment to conduct comprehensive and detailed testing of each system of the excavator to ensure that the quality and performance meet the standards.
In short, buying a second-hand excavator requires caution and careful identification, and choosing a formal, professional and honest second-hand dealer to avoid pitfalls and buy cost-effective and reliable equipment to the greatest extent.
