Comparison of the advantages and disadvantages of second-hand excavators of different brands

　　The choice of excavator brand is particularly important. Different brands have distinct characteristics whether they are new or second-hand. They are concerned about working performance, fuel economy, maintenance cost and durability. The value retention rate of different brands of second-hand excavators varies greatly. In addition, there is still a certain gap in performance when different brands of excavators choose different types of engines. The choice of materials for the excavator and the matching of the adjustment performance of the hydraulic system will affect the life of the excavator in the later stage. The following is a comparative analysis of the advantages and disadvantages of several major excavator brands:

　　1. Caterpillar

　　This is a globally recognized excavator manufacturer brand. Its excellent performance makes it extremely popular in the second-hand market and a brand that is very popular with users. It uses its own power system, has a high selection of materials, and its internal structure layout and detailed equipment are very user-friendly. In the entire field of engineering machinery, Caterpillar is the top existence, especially in heavy engineering and geological hard materials. Compared with the same level, the efficiency will be significantly improved, but the fuel consumption is high, which increases the operating cost. The original parts purchased for later maintenance are expensive, but there are still many cheap parts that can be installed and used, but the durability is far less than the original parts.

　　2. Komatsu

　　Komatsu excavators are well-known in the industry for their durability and applicability. They are suitable for different types of working environments. Komatsu's medium and large excavators basically use Cummins engines, which have excellent fuel economy performance and can greatly reduce operating costs. The parts are widely available, and later maintenance and repair are relatively convenient. Komatsu is also a popular brand in the second-hand excavator market. The value retention rate also means that the price of second-hand excavators is high, the later maintenance cost is average, and the original parts are still high, especially if the core assembly exceeds the warranty period, the replacement price is very high.

　　3. Volvo

　　Volvo has always been highly praised in the industry for its high fuel efficiency, advanced environmental protection technology and extremely fast working speed. Volvo's cockpit is comfortable and can reduce operator fatigue for a long time. The experience is excellent. In particular, medium and large excavators are not inferior to brands such as Caterpillar and Komatsu in terms of working performance. The main disadvantage is that the value retention rate is low. In the second-hand market, you may spend less money to buy an excavator of the same year, which is obviously not cost-effective for new machine users.

　　4. Hitachi

　　Flexible operation and precise movements. In the field of small and medium-sized excavators, Hitachi has always been the main model. It has a large user group in the world and has received great reviews. Hitachi's hydraulic system design is excellent. The reaction speed and working smoothness can bring high-quality working experience to the operator. The later maintenance cost is low, and the convenience of parts purchase is very important for users. However, its performance in the later stage is slightly inferior to that of brands such as Caterpillar. The value retention rate is generally recognized by users in the second-hand market.

　　5. Doosan

　　Doosan has been acquired by Hyundai of South Korea. The predecessor of Doosan is Daewoo of South Korea. The current prices of new and second-hand machines are low and the performance is excellent. For users with insufficient budgets, new machines or second-hand machines are very good choices. They can be competent for various types of work. The later maintenance and repair costs are low, and the price of accessories is lower than the above brands. At present, the new Doosan series is very popular in the European, American and Asian markets. However, it is inferior to Caterpillar and Hitachi brands in technology. At present, Doosan is equipped with its own engine, and there are fewer classifications in models, which leads to the use of the same engine for several models. Intelligent operation is also slightly inferior, but the price is lower than the above brands. Tiedou believes that Doosan is one of the best choices for buying new or second-hand machines. The fuel consumption performance and environmental emission of the new models are also in full compliance with the standards set by various countries.

　　In addition to the above models, brand construction machinery such as Kobelco, Liebherr, Bobcat, Kubota, Sumitomo, Kato, Ishikawajima, Sany, etc. have unique advantages and technical characteristics. There are too many excavator brands to choose from. Buyers should consider the local country's later maintenance and parts purchase and price considerations to reduce the cost of use. The purchase of second-hand machines also needs to choose large construction machinery sellers such as Tiedou. In addition to reliable and sufficient supply, we also provide spare parts purchase and warranty services that other sellers cannot provide.
