Rotation adopts close-circuit system.2. Rack and pinion for push&pull,Website:http://www.yikuangdrilling.com, with high efficiency, working stability..3. Push&pull and clamp adopt auto-variable system, load-sensitive control.4. 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.5. Simple electric circuit, low failure rate.6. Wire-control walking system ensures safety during travelling.7. Advanced hydraulic system raises 15-20% productivity than traditional one, reduces 50% heat and saves 15-20% energy.8. Main parts are chosen from international first class producers, highly increasing products performance reliability.Demision of drill pipeThreadGradeMin. bending radius (m)Length of pipe to bend 90° (m)Max. angle (°s)Max. slope pipeTorque (Kn.m)SpecificationOD of tube (mm)Thickness of tube (mm)Length (m)Weight (kg)OD of joints (mm)Big clamp space of pin joint and box joint (mm)50(2")506.522057Pin:110As customizedS3047.14.88.332.525Box:17560.3(2 3/8")60.37.52.52667Pin:130As customizedS3351.85.29.16.3337Box:18073(2 7/8")73834680Pin:120NC23S4570.73.85134.565Box:18073(2 7/8")731035888Pin:120NC23 NC26S51804.57.816478Box:18076 (3")761036088Pin:100NC26 D50S56874.7816.5478Box:19083(3 1/4")831036792Pin:130D80S65102.146.9184.580Box:19089(3 1/2")88.9104.5100104Pin:150D80 NC31S72
