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. The transport support fixture may be secured by means of a latch arrangement to the upper luminaire mounting platform during transportation and storage of the truss section assembly with the mounted lighting instruments. The transport support fixture contains interchangeable head cradles that mate with the external profile of a lighting instrument in order to minimize the movement of the lighting instruments during transportation.
