  • Patent number: 5432691
    Abstract: A lighting truss utilizes a drive assembly to facilitate movement of lighting instruments between a protected transport position and a deployed position, extending the lighting instruments below the truss for operation. Once deployed, means are provided for spreading the lighting instruments apart from one another to allow unimpeded pan and tilt operation of the lighting instruments and allow for storage of the lighting instruments in a relatively small truss.

  • Patent number: 5278742
    Abstract: An automated truss module for the support, transport and storage of lighting instruments is comprised of an upper luminaire mounting platform for mounting the lighting instruments and a separable transport support fixture. A truss section assembly, capable of being suspended above a performance area, is comprised of the upper luminaire mounting platform mounted to a section of box truss by utilizing helical isolators that provide a study cushion against shock and limit the transfer of vibration between the upper luminaire mounting platform and the box truss. The truss section assembly utilizes a motorized drive assembly to facilitate the transfer of the lighting instruments between a protected transport position, and a deployed position extending the lighting instruments below the truss section assembly for operation. Interchangeable adaptors for accommodating various types of lighting instruments are utilized for mounting the lighting instruments to the upper luminaire mounting platform.
