Disc-type drilling rig
Disc-type rotary drilling rig is mainly used for drilling large-diameter deep water wells, geothermal wells and engineering foundation pile holes. Unlike power-head drilling rigs with flexible rotation and high efficiency, it adopts a rotary disc driving structure with greater torque and stronger hoisting capacity, and is suitable for complex geological strata such as pebbles and weathered rocks as well as long-term heavy-duty construction of large-diameter deep boreholes.
