TECHNICAL FEATURES
v The rig adopts the advanced AC-DC-AC electric drive technology and the PLC enables intelligent driller control;
v AC VFD motor drive enables the stepless speed regulation of drawworks, rotary table drive and mud pump.
v The front side of substructure is high and back side is low. The drawworks is fixed at low position on the back side and the drill floor is flat with larger operation area;
v The drawworks is equipped with dual-shift gear box transmission, auto-driller, hydraulic disc brake and dynamic brake;
v The rotary table has one or two shifts with independent gear drive;
v The drilling line is of compacted strand wire rope;
v HL-type high-pressure (7,500psi) mud pump is equipped.
