1.The whole rig is very compact, which requires small installation space due to it's high integration . 2.The heavy-duty and self-propelled chassis:8x6,10x8,12x8,14x8,14x12,16x12 and hydraulic steering system isutilized respectively, which ensures the drilling rig good driveperformance, cross-country capability and lateral stability andcredibility of every component. 3. the reasonable assembly of theengine and the transmission box can ensure high driving efficiency andworking reliability. Draw works and rotary table can be driven byelectrical power. 4. the main brake could be disc brake or bandbrake, and the auxiliary brake could be air brake-water cooling-thrustdisc brake or water brake. 5. the rotary table transmission boxprovides forward-reverse shift, which can be suitable for positive andnegative DP rotary operations, and the anti-torque releasing device canbe used to make the DP deformation force released safely. 6. themast, which is front-open and double-section type with an inclinationangle is an erective double-section type, can be raised up or laid downand telescoped hydraulically. 7. the drill floor is twin-bodytelescoping type or with parallelogram structure, which is convenientfor easy hoist and transportation. The height of the drill floor can bedesigned and produced in accordance with the clients requirements. 8.the perfect configurations of the solid control system, well controlsystem, hi-pressure manifold system, generator house, engine pumphouse, doghouse and other auxiliary facilities can meet users differentrequirements.
