The main feature of the so-called ‘long reach’ drill rigs is the advanced mast articulation system, supporting an infinite number of mast inclinations and positions. The double boom articulation allows for quick and precise positioning on the hole of a large work area, with absolute efficiency of movement and reposition. This system is ideally suited to perform soil nailing and anchoring works on job sites with challenging terrain (embankments, slopes, road edges, high excavation fronts etc.) . The ‘long reach’ drilling rigs offer the best solution for earth retention and slope stabilization works that use rotary-percussive drilling for the installation of self-drilling hollow bar systems. This fast and easy installation method enables soil nails, rock bolts, micropiles and ground anchors to be installed into a range of ground conditions, overcoming problems with fill soils, loose or collapsing soils without the need for a casing and ensuring placement of the reinforcement to full depth. The MC 9, combining stability and reach, has been optimized for these kinds of applications to include different boom and mast configurations, a wide choice of drifter options and specially developed rod handling solutions.
