Articulated or “spider excavators” are ideal tools for steep, limited access sites. GSI® maintains a full fleet of these rigs, which can be used for mechanical scaling, high-angle excavation, or excavation activities in environmentally sensitive site. Because these rigs can “walk” rather than using tracks, they can even be used in active streambeds.
GSI® also fits all of its spider rigs with purpose-built drill attachments. These drills can install SuperNails®, rock bolts, SuperMicropiles™, or tensioned anchors on slopes up to 70 degrees (0.36:1).
