SH Series Rotary Drilling Rig

Our SH Series rotary drilling rig is widely applied for the construction of high building, bridge foundation, water conservancy projects, etc. It is especially good for the complex stratum containing much water. SH series products are more reliable in working, better accurate in drilling hole due to the triangle structure compared with SD series.

Typical product:
