ABSTRACT:
A self-climbing stage lighting system having a self-climbing apparatus and a light bar is disclosed. The self-climbing apparatus is hung from cables that extend approximately vertically from a fixed endpoint. The self-climbing apparatus includes an elongated support member and a linear actuator that drives travels sheaves along a portion support member. Responsive to the travel sheaves being driven in a first direction, the self-climbing apparatus climbs cables. Responsive to the travel sheaves being driven in the direction opposite the first direction, the self-climbing apparatus descends the cables.
