Description:

•    The drawworks and mud pumps are driven by "diesel engine+torque converter or                    
coupling transmission+chain compound" while rotary table is driven by AC rig123.net' target='_blank'>VFD                    
motor or DC motor to obtain smooth speed change and torque limit for better drilling performance；                    
                    
•    Rig floor is in two levels.Power and transmission system are installed on the rear low level；                    
                    
•    Drawworks is inner speed change.Speed shift adjustment and change is easily                    
available by remote pneumatic control;                    
                    
•    Main brake is hydraulic disk and auxiliary brake is electric magnetic eddy brake;                    
                    
•    Box or front level with swing lift and rear level with box type substructure is available；                    
                    
•    Ample space on rig floor is available for convenient operation；                    
                    
•    Module design is provided for reasonable arrange-ment, power compensation and                    
high use ratio;                    
                    
•    Compound can be used to drive the energy saving generator and automatic air compressor;                    
                    
•    Top drive drilling system can be equipped;                    
                    
•    Integrated skid rail may be provided to meet requirements for cluster well drilling.
