TD-6R drilling rig is a type of multi-purpose drilling rig of medium-shallow hole drilling for mineral exploration and geotechnical drilling. It not only is for RC core sampling drilling, but also for diamond wire-line core drilling. It adapts modular design, it can carry out multi-purpose by changing different modular top-drive head. Brand new designed top-drive head use mechanical and hydraulic together to shift speed, to make the head has wide speed range to suit for different drilling technology.
TD-6R is mainly used for solid mineral exploration, micropile hole drilling, and slide-resistant pile construction; Geothermy hole drilling, and water well drilling as well.
