New long hole drilling rig Simba S7 D enters the South American market

The Simba S7 D is now available for long hole drilling in the small to medium range drift size. Focus has been to develop a versatile, reliable and safe drill rig for mining conditions. The rig is built upon a modern design with many common components with the successful Boomer S1 D face drilling rig.

The Simba S7 D will be the direct replacement for the well proven Simba 1257.

This Simba model has an efficient hydraulic direct control system with manual functions. The use of hydraulic pilot signals made it possible to create an ergonomic and convenient operators environment with all functions within reach from the operators seat.

The Simba S7 D has the drilling unit mounted on a boom providing excellent reach and versatility. The Simba S7 D can be used in many applications such as long hole drilling, production drilling and when cable bolt holes are to be drilled. A carousel attached to the drilling unit makes the drilling process fully mechanized, efficient and most important of all, safe for the operator.

  • Higher ground clearance

  • Communality in parts with the Boomer S1 D
  • Possibility to carry a water hose reel

An environmentally friendly Tier 3/ Stage IIIA diesel engine for tramming is built into a modern design chassis. The optional cabin of course meets the requirements from the authorities with FOPS approved roof and noise levels. And by the way, to make the operator happy we added air conditioner and HiFi sound system in the cabin, a happy operator means more drill meters!
