- Rotation adopts close-circuit system.
- Rack and pinion for push&pull, with high efficiency, working stability.
- Push&pull and clamp adopt auto-variable system, load-sensitive control.
- Large torsion motor drives rotary mechanical manipulator for loading and unloading drill pipes, with adjustable overturning angle up to 220°. Rapid and convenient loading and unloading drill pipes largely reduces labor intensity and increases productivity.
- Simple electric circuit, low failure rate.
- Wire-control walking system ensures safety during travelling.
- Advanced hydraulic system raises 15-20% productivity than traditional one, reduces 50% heat and saves 15-20% energy.
- Main parts are chosen from international first class producers, highly increasing products performance reliability.
- Fit to two kinds of drill rod: Φ73×3000mm /φ89×4500mm.
