Abstract
A stage installation for vertical movement of multiple stage elements has a computer controlled winch assembly comprising a support member having a channel, a platform adjacent the support member, electrical control and electrical power raceways in the channel, and a multiplicity of winches supported on the platform. The winches include a housing, a bidirectional servomotor, a rotating drum driven by the motor in either direction to haul or pay out cables operatively connected to the stage elements. Connectors are coupled to the electrical power and electrical control raceways, and a remote computer terminal transmits signals to the winches to initiate and terminate operation of the servomotor.
