YFB-2 Rock Tunnel Non-Blasting Tunneling Drilling Rig
The YFB-2 rock tunnel non-blasting tunneling drilling rig is primarily used for rock tunneling construction projects in railways, highways, underground spaces, water conservancy, hydropower stations, and urban underground pipelines, where blasting methods are not applicable. It features a novel design, a long power head feed stroke, high rotational speed, and strong process capabilities, suitable for large-diameter diamond coring or full-face drilling operations. Compared to conventional electric rock drills, this rig has significant advantages: large torque and drilling pressure, stable drilling, dual columns, dual masts, and dual power heads, each with independent control and adjustable angles, allowing simultaneous construction in both horizontal and vertical directions.
