What is rotary drilling rig?
A Rotary Drilling Rig is a professional heavy-duty machine designed for deep foundation drilling in construction, mining, and infrastructure projects. It relies on a rotary drive system to rotate drilling tools, with the Kelly Bar serving as its critical component—transferring torque from the drive to the drill bit while extending or contracting via telescopic sections to adapt to different drilling depths. Widely used for piling, creating large-diameter holes, and building deep foundations for buildings, bridges, and other structures, this rig combines efficiency, adaptability, and precision to meet the demands of complex engineering scenarios.
