Abstract
A side-shift raise climbing system is provided that utilizes a side-cut excavated into the wall of the access drift for a raise in a mine. A transfer section is incorporated into the existing length of rail servicing the raise. The transfer section includes a laterally transferable rail that can be detached from the existing rail and shifted along a set of monorails that extend into the side-cut. The transfer section enables a raise climber, when parked thereon, to be shifted out of the access drift without requiring additional access drifts or parking/nesting areas to accommodate the use of muck removal equipment.
