Descender – Escapeway

CIS- Descender Escapeway Modular Raise Lining System

A Modular Solution To Escapeway & Vent Raise Lining

Descender is a permanent, modular lining system for raises. Components are installed in compression, descending from top to bottom. Installation of the solid-steel Escapeway components can be completed in days, providing a safe and fully enclosed method of egress with the added security of stamped and engineered tie-off points, landings and handrails.

  • Safe installation
  • Small work area footprint
  • Easy to mobilize and set-up
  • Installations completed in days
  • Fully customizable to meet your requirements



Safe Egress/Air Supply

Escapeway and ventilation needs are always changing as we mine deeper at an accelerated rate. Sub-levels are further apart due to more accurate blasting, and mechanized methods of mining are creating massive excavations with reduced stope access points resulting in fewer ventilation options. There is an ever-growing demand for more efficient, more reliable and safer means of fulfilling egress and ventilation requirements. Descender is CIS’s innovative modular solution to rapidly constructing escapeways, and lining vent raises.
