ABSTRACT:
The invention is a crane system for a building for the assembly of a gas bag for a lighter-than-air vehicle, the building having a floor and a roof thereover with a longitudinal, vertical and lateral axis. In detail, the crane assembly includes a plurality of crane carriage rail assemblies in the form of arches aligned with the lateral axis of and mounted within the building. The carriage rail assemblies are in a spaced relationship along the longitudinal axis. A plurality of crane carriages are movably mounted on each of the crane rail assemblies with each carriage including a winch mounted thereon having an extendible and retractable cable. A control system is provided for moving the crane carriages by rows aligned with the longitudinal axis of the building along the crane carriage rail assemblies to specific locations along the lateral axis and for adjusting the length of the cables of the winches in each of the rows as a function of the distance of each of the rows along the lateral axis of the building.
