The origins of micro-excavators can be traced back to the early stages of development of digging machinery. Since the 1980s and 1990s, with the rapid development of urban construction, the demand for small and flexible construction machinery in municipal engineering and traffic engineering is increasing day by day. In this context, the micro excavator came into being and gradually developed into a representative construction machinery in urban construction.
From a historical point of view, the power plant of excavators has undergone an evolution from steam drive to electric drive and internal combustion engine drive. With the application of hydraulic technology, the hanging excavator equipped with hydraulic backhoe on the tractor appeared in the 1940s, which laid the technical foundation for the birth of the micro-excavator.
The main technical features of mini excavators include small size, light weight, flexible operation and easy maintenance. These characteristics allow it to maximize its production capacity in the narrow working space of the city.
In terms of classification, according to the weight of the whole machine, the micro excavator can be defined as a mining machine with a weight of less than 6 tons. Although this classification standard varies in different industries, it generally reflects the trend of miniaturization and lightweight of micro-excavators.
The structure of the mini excavator is generally composed of a power device, a transmission device, a walking device and a working device. The working principle is to excavate the material above or below the bearing surface with a bucket, and load it into a transport vehicle or unload it into the earthmoving machinery of the storage yard.
Micro excavators are widely used in a wide range of fields, including but not limited to municipal road engineering, house decoration, rural self-built housing road expansion, tunnel construction, landscape work, vegetable greenhouse excavation, steel furnace slag removal and high danger operations.
In the municipal road project, the micro excavator has become the best choice to excavate the trench and fill the pipeline in the foundation pit because of its small size and strong flexibility. In house decoration, micro excavators can efficiently remove rotten holes in the wall. In the expansion of rural self-built houses and roads, micro-excavators can significantly improve the working speed. In addition, micro excavators are also suitable for landscape work in narrow Spaces, vegetable greenhouses excavation, and steel furnace slag removal in extreme environments.
The advantages of mini excavators are mainly reflected in the following aspects: first, small size, easy to transport and store; Second, the operation is flexible, can adapt to a variety of complex terrain and working environment; Third, the initial capital investment is low, reducing the economic burden of users; Fourth, the maintenance is simple and reduces the later operating costs.
With the continuous deepening of urban construction and the continuous progress of technology, micro-excavators will show the following development trends in the future:
First, the level of intelligence and automation is improved. Through the introduction of advanced sensors, control systems and artificial intelligence technology, micro-excavators will achieve more accurate and efficient operation.
The second is the improvement of environmental protection and energy-saving performance. With the enhancement of environmental awareness and the promotion of energy conservation and emission reduction policies, micro-excavators will adopt more environmentally friendly and energy-saving power systems and transmissions.
Third, the development of multi-functional and customized services. According to the needs of different users and the characteristics of the working environment, the micro excavator will provide more multi-functional and customized service solutions.
