• Features
- • Drive mode of “diesel engine + reducing gear box + narrow V belt compound” is available. The power is reasonable distributed for higher efficiency.
• Either inner or outer speed change is optional for drawworks. Speed change is easy and fast by remote pneumatic control. Main brake is either band brake or hydraulic disc brake. Electric magnetic eddy current brake or EATON brake is option for auxiliary brake.
• For drilling rig over 4000m in drilling depth, rig floor is in two levels which is “front high rear lower”. Power and transmission system are installed on the rear low level and the rig power is transmitted to drive rotary table and catworks located on drill floor through bevel gear reducer and universal shaft.
• Module designed, advanced technology, easy for assembly and disassembly.
• With bailing drum, mechanical friction cathead and rotary table drive device.
• Independent driller cabin is on the user’s requirements. To realize intelligent control of pneumatic, electric, hydromantic and instrument system so that driller completes the total operation in the cabin.
• Independent automatic drilling system could be equipped as the client’s requirement.
• Top drive drilling system could be supplied.
