Product Description

Chinese Famous Brand 90M Rotary Drilling Rig SR285R

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.

Economical and Energy-saving
· Imported large-displacement EFI engine with solid power, adopts power optimization control technology, adjusts power distribution in real time, fast response speed, higher fuel efficiency, and more energy-saving.

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.

Intelligent Upgrade
· 10-inch HD touch screen, fast response, and more convenient operation.
