ZJD2800 / 180C Full Hydraulic Reverse Circulation Drilling Rig for Vertical Well

ZJD2800 / 180C Full Hydraulic Large Diameter Drill Rig Reverse Circulation Drilling for Vertical Well Drilling Construction of Pile Foundation

ZJD2800/180C full hydraulic drilling rig is mainly used for drilling construction of pile foundation

and vertical well with large diameter and depth in complex geology. The maximum drilling diameter

and depth are 2.8M and 150M, the biggest embedded rock strength can reach 200MPA.

It is Widely applied in drilling construction of large building on land,port and pier,river levee protection,

and river, lake, sea bridge pile foundation, and it’s the main model of large diameter pile foundation

construction.
