Tiedou's used excavator recommendation (Komatsu No. 3) 2-4 ton Mini excavator parameter configuration comparison

　　The market competition for small and medium-sized excavators is fierce. Except for developing countries, the market retention rate of excavators has been saturated except for equipment that needs to be replaced. Especially with the slowdown of construction in cities, urban infrastructure has changed from large-scale development to small projects and details. This also means that the demand for small and medium-sized construction machinery has decreased, and the market demand for Mini excavators has increased. At the same time, the advantages of Mini excavators have also been revealed. First of all, small-scale urban road reconstruction and maintenance, urban greening paving, urban canals, water pipes, circuits and other equipment can all use Mini excavators. Considering the size, noise, and working capacity, Mini excavators can already meet most work needs. Of course, some areas with higher work levels still need larger types of construction machinery.

　　Considering the fuel economy of Mini excavators and the convenience and pollution-freeness of lithium battery Mini excavators, many cities have purchased Mini excavators. It has become the mainstream. In addition, rubber crawler plates can move on the road without damaging the road surface, and the small construction range does not affect traffic. Compared with manual labor, it is more efficient and has lower costs. Especially in developed countries, the use rate of Mini excavators is very high. Mini excavators are very suitable for personal use or corporate or government procurement. Komatsu has launched 25-35 models of excavators with many types to choose from, to meet user requirements for different work needs and environments. The performance of the 5 Mini excavators recommended by Tiedou today is very outstanding.

　　In Mini excavators, everyone should have this basic understanding that the difference between performance parameters is not big. The main type of work of Mini is to replace manual labor for small projects. Mini excavators can perfectly replace most of the manual labor within their own weight and working range, especially now that Mini can be equipped with various types of accessories, whether it is excavation, crushing, planting or canal and small pipeline laying, there are suitable equipment to greatly improve the requirements of manual work. Of course, the disadvantages of Mini excavators are still small size and no cab installed. In harsh environments and high temperature environments, workers need to overcome certain environmental difficulties.
