Rotary drilling rig is a key engineering equipment for the construction of electromechanical liquid highly integrated and large diameter deep hole pouring piles. It has the characteristics of large torque, flexible maneuverability, high construction efficiency and multi-function. It can be equipped with long spirals, short spiral drills, rotary buckets, core drills, hydraulic pile hammers and other drills. It can be drilled into clay layer, sand and pebble layer. And the middle of the weathered rock layer. It is suitable for soil geological conditions in most areas and is widely used in foundation engineering construction of roads, bridges, wharves and high-rise buildings. Shanhe intelligent series rotary drilling is the most complete domestic spectrum. The output torque of the power head is from 40KN.M-520KN.M, the construction aperture is from 350mm to 3500mm, and the maximum construction hole depth is 125 meters. Its theoretical system has formed the only two monographs in the professional field - "Rotary Drilling Rig Research and Design", "Rotary Drilling Rig Equipment, Construction and Management", and the product export rotary drilling rig hometown - Italy.
