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

TR250D-Rotary Drilling Rig
Dimensions
Crowd cylinder type
The TR250D rotary drilling rig has an operating weight of approx 74 ton . It is suited for:
● Rotary drilling
● Drilling cased boreholes (installation of casing by rotary drive)
● Drilling boreholes with long hollow stem angers(CAF system),with or without kelly extensions
TR250D Rotary Drilling Rig is mainly used in the construction of civil and bridge engineering, which adopts advanced intelligent electronic control system and load sensing type pilot control hydraulic system, the whole machine is safe and reliable.
