drilling performance.
● Both swing lift and sling-shot parallel-integrated substructures are optional. All parts on rig floor and mast can be installed on ground and raised with drawworks power.
● Main
brake of drawworks can be hydraulic disc
brake or band brake. Auxiliary brake of drawworks can be eddy current brake which is water cooling or air cooling or EATON pneumatic brake as the client’s requirements.
● Rotary table is
driven by drawworks power through compound
drive or by an independent
motor.
● Independent
driller cabin is on the user’s requirements. To realize intelligent control of pneumatic, electric, hydraulic and instrument system so that
driller completes the total operations in the cabin for better working conditions and lessening working strength. Logic control, supervision and maintenance during complete drilling operations are available by
PLC process. The drilling data can be stored printed and remote transmitted.
● Top drive drilling system can be equipped
