The racks will be received at LaSalle through the bomb-bay doors located on the Unit 1 side of the station..This entry is positioned between -column' rows 14 and 15 on row A. From this point, the racks will be lifted r L. to.the refuel floor through the equipment hatch directly west of the " bomb-bay doors. Once on the refuel floor, the modules will be installed or ' ~ stored depending.upon shipment schedules and installation progress. If the 7 ' racks cannot.be immediately installed, they will be moved into Unit 1 as ^ shown by path 1 on figure 10-2 to a suitable temporary storage location. s; . Racks to'beLinstalled will follow load path 2. During the movement of the p[ racks along.either. path 1 or 2, there are no obstacles over which the racks will have to.be lifted. -The normal height above the floor while a module is l traveling will bel limited to 1 to 2 feet.
