Abstract
A construct can include an access drift; a length of rail disposed in the access drift; a pair of raise climbers, each adapted to be supported by the rail; a turntable to which the rail is mounted, the turntable being adapted to support the rail, and a raise climber supported thereby, for movement about an axis; a nest disposed adjacent the turntable; and a plurality of rails, each extending from the turntable such that, when the turntable is operatively positioned, the rail of the turntable is aligned therewith, the plurality including at least a pair of curve rails and a nest rail, the curve rails each being adapted to develop a raise and the nest rail being positioned in the nest.
