The invention is a crane system for a building (20) for the assembly of a gas bag for a lighter-than-air vehicle, the building (20) having a floor (22) and a roof (24) thereover with a longitudinal, vertical and lateral axis (26A, B, C). In detail, the crane assembly includes a plurality of crane carriage rail assemblies (30-38) in the form of arches aligned with the lateral axis (26C) of and mounted within the building (20). The carriage rail assemblies (30-38) are in a spaced relationship along the longitudinal axis (26A). A plurality of crane carriages (40A-I to 48A-I) are movably mounted on each of the crane rail assemblies (30-38) with each carriage including winch (96) mounted thereon having an extendible and retractable cable (98). A control system is provided for moving the crane carriages (40A-I to 48A-I) by rows aligned with the longitudinal axis (26A) of the building (20) along the crane carriage rail assemblies (30-38) to specific locations along the lateral axis (26C) and for adjusting the length of the cables (98) of the winches (96) in each of the rows as a function of the distance of each of the rows along the lateral axis (26C) of the building (20). |
