AT-3000L frame integral type shaft drilling rig is a heavy-duty shaft construction equipment designed for your large-diameter, deep-hole and high-stability needs. This equipment adopts an integrated rigid frame structure, abandons wheel-rail or articulated mobile design, and sacrifices some flexibility in exchange for stronger drilling stability and construction accuracy. It is suitable for fixed workstations, ultra-hard rock formations or mines and hydropower projects with ultra-large diameters.
