Portable DC High Voltage Generator
The development of small excavators mainly depends on the development of urban construction and new rural construction. Due to the urban transformation and construction, more construction time is required, and agricultural production is mechanized. Construction machinery has little impact on the surrounding environment, safety, low pollution, The slewing radius is small, easy to transport, and has an appearance that is in harmony with the city scenery. The Small Excavator has many functions of a medium-sized excavator, and has the advantages of convenient transportation, low energy consumption, high flexibility, wide adaptability range, high efficiency, etc. It is very suitable for the construction site with a small space and has been sold Go overseas.
