Abstract
A movable conveyor (10) comprising a platform (24) for carrying a soccer field (12) or the like, and pairs of sled assemblies (26). Each sled assembly (26) includes a shoe (42), a pair of linear hydraulic motors or actuators (60, 62), a plastic bearing (79), and an expandable air bag (83). Air bag (83) inflates to raise platform (24), while actuators (60, 62) operate to move platform (24) along shoe (42). With air bag (83) deflated, platform (24) rests on a foot support (38). This allows actuators (60, 62) to reposition shoe 42 to a forward position, to again raise and move platform (24).
