ABSTRACT:
A gangway system for providing access, particularly for handicapped persons, between structures having surfaces which are relatively movable with respect to each other over a range of motion. The gangway includes a plurality of alternating ramp and platform members hingedly coupled to one another, the ends of the gangway being in contact with the surfaces of the structures. The platform members are supported by support members fixed in position relative to one of the structures and, over the range of motion, as the surfaces move vertically relative to one another the ramps and platforms come to rest in sequence adjacent the surface of the other structure. The lengths of the ramps are selected to be less than a preselected value and their slopes are selected so as not to exceed a preselected value during use so that handicapped access is facilitated.
