Abstract
A bridge for the transfer of passengers between an elevated level of a terminal building has a vestibule attached to the terminal building. A first bridge unit extends from the vestibule to a rotunda assembly and is rotatably attached to the rotunda assembly and the vestibule. The rotunda assembly has an elevation system for changing the slope of the first bridge unit relative to the horizontal. A second bridge unit extends from the rotunda assembly and has a bubble attached at its outer end. The second bridge unit has telescoping sections and is movable vertically, telescopically and radially upon operation of a driving system connected at the outer end of the second bridge unit. A telescoping brow extends away from the second bridge unit. The slopes of the first bridge unit and the second bridge unit are controlled to be less than 12 percent with the bubble being movable over a wide range of locations and with a substantial range of vertical motion.
