The Simba S7 is built upon a modern design sharing many components in common with the successful Boomer S1 face drilling rig. It is a long-hole drilling rig for small- to medium-sized drifts in the 51 to 89 mm hole range. The rig is capable of ring drilling with parallel holes upward and downward with up to 5,9 m spacing. Equipped with a high-performance tophammer rock drill and boom-mounted drilling unit the Simba S7 offers a sustainable high-precision solution for long-hole drilling.
