Mechanical System

The main winch hydraulic oil confluence technology improve the winch speed by 50%Crowd force stepless adjustment improve construction efficiencyThe rotary drive self-adaptive drilling system and high speed spin-off system improve drilling efficiency

Reducer, motor, pump, valve configuration of the international first-class brand

The broken line reel technology and the winch patent technology make the service life of wire rope improve greatly

Rotary Drive multi-stage damping structure improves the borehole verticality and structural life

Reasonable layout, repair, maintenance are convenient

Kelly drilling and CFA drillingCaterpillar Undercarriage

Caterpillar Undercarriage structure and the mast structure, all materials are special high-strength steel

Cross Roller Bearing improves the drilling accuracy significantly
