Abstract
A battery powered raise climber system is provided that uses Lithium ion batteries to drive a single or double electric drive for an existing raise climber. The batteries offer a faster, safer, quieter and cleaner way to move workers and their equipment to and from the work face in a raise and eliminates the need for adding lengths of hose as the raise climber ascends and eliminates the emission of harmful inhalants. The battery powered system also enables high efficiency area lighting to be used at the work face, and as the raise climber descends in the raise, the electric drives can reverse operation to recharge the batteries.
