Zusammenfassung:	A retractable roller system for handling cargo has a main channel (14), a pneumatically actuated bladder (17) mounted along the bottom of the channel and a roller tray (30) on which a plurality of roller members (32) are rotatably supported. Extending outwardly from each of the opposing side walls of the roller tray is a flange member (31a, 31b), the flange member of one of the walls being at a lower level therealong than the flange member of the opposing wall. Extending inwardly from each of the side walls of the main channel is a flange member (14a, 14b), the flange member of one of the channel walls being at a lower level therealong than the flange member of the other channel wall. The rollers are raised to an "up" position by inflating the bladder. In a lowered position, the roller tray can be readily removed from the channel by sidewise tilting which permits the side flanges of the roller tray to clear the side flanges of the channel.
