The hydraulic elements of ZT-150 Directional Drilling Rig (including hydro pump, motor, Pressure valves, oil hoses etc.) are all the original products from the famous transnational companies and the diesel engines are products from the joint venture of Cummins with strong power and reliable performance. Drilling rigs and power station adopts integrative propelling mechanism of the track chassis of excavator with convenient movement and strong maneuverability. The rotary head is driven by the plunger motor and with high rotary speed and large torque. The feed mechanism is driven by a gear-rack transmission. Both of feed force and the Pullback force are 1500 KN. The drill rods are fastened and loosed by the dual-clamping device with high speed for pulling rod and high efficiency. 3T hydraulic hoist arm accreted the Drilling Machine, and is convenient for engineering, also, it is suitable for the installation of the long distance and larger diameter pipes.
