TECHNICAL FEATURES
v The rig adopts the advanced AC-SCR-DC electric drive technology;
v The front side of substructure is high and back side is low. The drawworks is fixed at low position on the back side;
v The PLC enables intelligent driller control;
v The drawworks is of integral structure with internal speed regulator. The main brake is hydraulic disc brake and the auxiliary brake is electro-magnetic eddy current brake or EATON brake. Auto-driller is also equipped;
v The rotary table has one or two shifts with independent gear drive;
v The front side of substructure is high and back side is low and the drill floor is flat with larger operation area;
v The drilling line is of compacted strand wire rope.
