Disclosed is a supplemental lift system for use with an aircraft passenger boarding bridge of a type that includes a tunnel section for being extended over the wing of an aircraft in a cantilever-like fashion. The supplemental lift system is for use in an event that a main elevating mechanism of the passenger boarding bridge is other than operable, such that the over the wing portion of the boarding bridge may be moved out of the way of a wing of the aircraft, permitting the same to move in a direction away from the boarding bridge. A preferred embodiment of the supplemental lift system comprises at least a jack including a first portion that is mounted to the aircraft passenger boarding bridge at a point that is distal from an outboard end thereof. The at least a jack further comprises a second portion having a first end for being telescopically received within the first portion such that a length of the jack is variable, and a second end for engaging an area of the ground that is elevationally below the aircraft passenger boarding bridge. The supplemental lift system also includes a power source in communication with the at least a jack for providing the power required for extending the length of the jack.
