Abstract
A motorized fly system winch, drum and carriage combination for raising and lowering, for example, theatre scenery by means of cables and which incorporates functions for emergency braking, for moving the drum in synchronization with relation to the carriage containing cable-guiding means and for driving of a limit switch if desired. The winding and unwinding the cables on or off the drum does not change the cable runs relative to the theatre. The fly system winch can be installed at the sides of the stage, up at the stage gridiron, or above the gridiron. With this combination, counterweights are unnecesary. The fly system winch is compact and can be economically manufactured.
