ABSTRACT:
Modules (30) include lateral bearing beams (32) for distributing cargo loads over a cargo compartment floor (4). Roller trays (34, 34', 34") are secured to and extend longitudinally between the beams (32). A tie-down support beam (38) is secured to and extends longitudinally between outboard portions of adjacent bearing beams (32). The support beam (38) is anchored to a rail (12) mounted in the floor (4). A side guide (40) is attached to of the bearing beams (32) and carries vertical restraint members (46) and a longitudinal restraint latch (48). Adjacent modules (30) are connected by slip joints (68). A cargo tray (80) has sloping sides (86) to conform to curving cargo compartment sidewalls (6). Slots (102) on the sides (86) engage the restraint members (46). The tray (80) has an outer shell (82) and a corrugated inner shell (90) with ridges which form support surfaces ( 98) coplanar with a peripheral horizontal lip (106). Spans between ridges (98) and the lip (106) are dimensioned to support standard size boxes.
