In recent years, with the urban construction and infrastructure becoming more and more perfect, more and more small scale construction and reconstruction projects for mature urban area, and provided new opportunities for small Rotary Piling Rig Manufactures. Small Rotary Piling Rig developed rapidly in the engineering market is not accidental. It is widely used in the construction industry and the railway construction with the advantages of small footprint, quick movement and flexible movement. Moreover, the drilling speed of the Rotary Drilling Machine is relatively fast, which is 5-6 times faster than old rotary piling rig, and greatly accelerates the project progress. In addition, the smaller size of the small rotary drilling rig overcomes the awkward situation that the construction site is small and machine is large. And the overall transport save freight, small space construction, flexible operation and high efficiency, low noise and little impact on the surrounding.
