A fully floating gangway comprises a movable frame sandwiched movably in an operating plane between lower and upper parallel bearing surfaces which are supported from and positioned below a first platform. A gangway extends from the frame's front end for extending to another platform such as an aircraft doorway so that the gangway can be aligned therewith by manipulating the frame in the operating plane. Preferably the frame and bearing surfaces are supported in a mobile structures such as passenger ramp. The gangway is preferably pivoted from the frame for adapting to differential elevations. The pivoting gangway can be counterbalanced for ease of manipulation. A braking system is provided to lock gangway against movement once positioned.
