Backhoe excavators are the most widely used earth-moving machinery, with the characteristics of flexible operation and fast turning speed. In recent years, the backhoe excavator market has developed rapidly, and the production of excavators has developed in the direction of large-scale, miniaturized, multi-functional, and specialized. Excavation of foundation pits can be based on actual needs, choose ordinary excavation depth excavators, you can also choose larger excavation depth extended boom, extended boom or telescopic boom excavators, etc. The main parameters of the backhoe excavator include the quality of the whole machine, the external dimensions, the standard bucket capacity, the walking speed, the slewing speed, the maximum digging radius, the maximum digging depth, the maximum digging height, the maximum unloading height, the minimum turning radius, the tail turning radius, etc.
The selection of the backhoe excavator should be based on the foundation pit soil conditions, plane shape, excavation depth, excavation method, construction schedule, etc., combined with the excavator operation method, etc.; in actual application, it should be based on the manufacturer's excavation The specifications, models and technical parameters of the machine products, combined with the construction experience of the construction unit for selection
