Rotation adopts close-circuit system.
Rack and pinion for push&pull, with high efficiency, working stability.
Pushand 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: ?73×3000mm /?89×4500mm.
