  • Variable speed system to motorize counterweight line sets
    Patent number: 9474988
    Abstract: A manual theatrical rigging system is motorized to achieve greater control of speed and accuracy, avoiding need to load counterweights, and without sacrifice of standard line-set spacing. Each line set has a wire-reinforced drive belt connected with the associated hand line, and is operated by a geared or gearless motorized winch. A winch support frame supports the motorized winches in a number of rows, with the winches in positions staggered from row to row. The counterweight arbor holds a fixed counterweight. A computerized control panel permits a single operator to manage the entire system of line sets. An overspeed safety brake brakes the line set if the movement exceeds a safe speed.
