Remarks:
| ||||
4.The power head is designed lightly, with strong torque, high construction efficiency and stepless speed change of two motors. 5.The structure of the upper guide frame ensures the perpendicularity between the drill pipe and the ground, makes the construction more convenient, improves the construction efficiency and increases the safety； 6. Hydraulic circuit system adopts advanced concepts and is specially designed for optimum design of rotary drilling rig. It has the characteristics of stable rotation and fast hoisting speed.
