Pile Top Drill Rigs ZJD4000 / 350C Full Hydraulic Drilling Rig for
Ultra-large Diameter Foundation Drilling in Mixed Ground
ZJD4000/350C 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 4.0M and 160M, 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
ultra-large diameter pile foundation construction
