Abstract: A spray paint system including a paint booth and paint robot apparatus movable within the paint booth and movably supported outside the paint booth is disclosed. The side walls of the paint booth have elongated openings formed adjacent the bottom of the paint booth to allow gooseneck-shaped saddle structures to extend therethrough. The saddle structures support paint robots on their respective elongated rail mechanisms. The side walls of the paint booth, together with the rail mechanisms defines stationary labyrinthian seals which isolate paint hoses, cables, bearings and ways from the booth environment. Each robot is mounted on its saddle structure by a hollow robot carriage. The robot carriage and saddle structures house the various cables, hoses and paint lines of their respective robot. Drive assemblies including racks mounted on their respective rail mechanisms drive the saddle structures along the elongated openings.
