High efficiency hydraulic

using imported Kawasaki hydraulic system

efficient and flexible

They are widely used in civil engineering in small dia. and deep borehole construction, high main hoist lifting up and down speed, tall verticality of the finished boreholes, and high working efficiency in civil construction.

special chassis

Telescopic large widening chassis designed for rotary drilling rig, roller type large diameter slewing bearing to guarantee the high stability in deep borehole construction.

High reliability

The mast adopts a box structure with solid resistance to torsion and fatigue; the sixth-generation Kelly bar adopts upgraded material and strengthened block ring; the overall strength increased by 25% with high drilling ability in the strongly weathered rock layer.
