The draw works is driven by two VFD AC motors with 1+1r/2+2r step-less speed, and reversal will be realized by ac motor reversal. The mud pump is driven by VFD AC motors, which are mounted on the rear skid of mud pump, with v-belt transmission and simple structure. The independent driven rotary table runs with 1+1r/2+2r step-less speed, and reversal will be realized by ac motor reversal. Using AC-DC-AC drive technology, rotary table and draw works are four quadrant running and full digital vector control. Single drum, gear driven and one / two shifts smooth speed change draw works is simple in structure and reliable in operation. Feed back / dynamic brake is adopted to replace eddy current brake as auxiliary brake. Automatic drilling is obtained by draw works main motor or an independent motor. Intellectual position control for traveling block prevents crown block and rotary table from collision. Real time communication and network is available by using profibus technology. K type mast is suitable for install top drive system. Sling shot or swing up substructure and mast are applied so that all the equipment can be installed at lower position. Suit for any transportation.
