Abstract
A motorized improved winch for raising and lowering, for example, theater scenery by means of cables and which incorporates a tubular support enclosure for supporting and housing a moving drum and the required components for driving, emergency braking and for moving the drum in synchronization with relation to the cable guiding means, preferably mounted on the tubular support enclosure, and for driving the electrical sensors if desired. A new feature of this improved winch includes alternate means for supporting the winch unit from the tubular support enclosure through rollers, mounted to the inside of the tubular support enclosure and engaging the support means part of the movable winch unit. Another new feature is an option to use more than one driving means for increased capacity. The improved winch can be installed at the sides of the stage, up at the stage gridiron, or above the gridiron.
