What brand is good to buy a second-hand excavator?

There are many options for buying a small excavator,Used excavatorNo exception, due to the relatively lower technical requirements for small excavators compared to large excavators, many brands of small excavators have entered the second-hand excavator market.

When choosing a brand for buying second-hand small excavators, multiple factors should be considered, such as cost-effectiveness, after-sales service, and actual operating conditions. Several second-hand small excavator models recommended by Shanghai Huacheng that have been purchased frequently and have a good reputation. 60 series: Komatsu 60-7, Daewoo 60-7, Kobelco 60, CAT 307.120 series: Komatsu 120-6, Hitachi ZX120, Kobelco 115, Kobelco 135, etc. Of course, these models have limited prices, please refer to them for detailsSecond hand excavator pricesDetailed quotation inside.

    1. Consider the manufacturer's reputation and the completeness of after-sales service

There are many manufacturers producing small excavators now. Before purchasing, it is advisable to conduct investigations on each manufacturer, such as understanding the usage of excavators through old users of various brands. If conditions permit, it is also possible to visit the factory or participate in exhibitions organized by various agents to learn about product quality assurance and performance information. Analyze and compare the collected information, and try to choose excavators with good reputation, sound sales system, and comprehensive quality assurance system. One of the important sources of information is to inquire about the usage of the excavator from the surrounding owners and operators. Manufacturers must have a comprehensive service system (including nationwide service agency situation, parts supply situation, service system within the warranty period, and maintenance service work outside the warranty period) to meet the maintenance and repair needs of construction units or individuals after purchasing equipment. If a manufacturer's service cannot be guaranteed, do not choose it even if the machine performance is good, otherwise it will bring a lot of trouble. The maintenance of excavators is very important, so the after-sales service capability of local agents is also an important reference factor in deciding whether to purchase.

   2. Consider the main tasks undertaken by the small excavator

Many engineering contractors are not limited to one type of project, so when choosing small excavations, it depends on whether they can complete the special project they undertake. If the excavator is only used for soil excavation, then the technical requirements and capabilities of the small excavation should be matched as much as possible. If the small excavator needs to work in various occasions and environments, it is required that the selected small excavator should have flexible performance, and at the same time, appropriate consideration should be given to the tooling accessories required for future work. For small excavation operations, excavation cycle time and excavation force are the most important parameters. The digging power determines what soil conditions the excavator can dig in and how much it can dig, while the operating cycle time determines the length of time the excavator spends from digging, unloading to digging again. To maximize the productivity of the excavator, the depth of excavation should not exceed 1/2 or 3/4 of the maximum excavation depth. If the engineering conditions only require 1/4 of the excavator's excavation capacity, it is possible to consider using an excavator with a shallower excavation depth instead of spending money on purchasing an excavator with excavation capacity greater than the actual needs.

    3. Consider whether the technology used in the small excavation is advanced

Advanced technology in small excavation can greatly improve operational efficiency. Therefore, how to treat the technical progressiveness of small excavators is also a very important aspect of purchasing small excavators. For example, some hydraulic systems used in small excavators are the same as those used in the company's medium and large excavators, which means that the technology is more advanced and can greatly improve work efficiency and reduce the workload of workers.

   4. Cost performance analysis of excavators

Generally speaking, when comparing equipment fuel efficiency, imported machines are more fuel-efficient than domestic machines, original machines are more fuel-efficient than joint venture machines, and Japanese machines are more fuel-efficient than European and American machines. Similarly, in terms of engine power, European and American models generally have the upper hand. Nowadays, domestic small excavator series have emerged as a rising force. Although they follow the path of high configuration and high price, they rely almost entirely on imports from engines to cylinders (the body steel is mostly domestically produced). Currently, most of them still lack core technologies. The core technology is not simply based on how many well-known accessories are used, but on the degree of compatibility and stability achieved in the overall assembly of the excavator. What kind of equipment is an ideal device? The answer is that the mainstream of construction site represents this technical requirement.

According to the experience of most friends who purchase second-hand small excavators, choosing excavator models from big brands and with good user reputation is often better.
