Abstract
There is disclosed an airplane passenger loading ramp defining a walkway having a cab at the free extremity thereof which includes a weather protective mating device for mating with the contour of an airplane around the entry door thereof. A generally tubular shaped fire protective shroud surrounds such sealing device and is connected on one end with the walkway around the exterior of such sealing device and has the opposite extremity thereof extendable telescopically over such sealing device to mate with the contour of such airplane. An operator is mounted on one end from the walkway and carries on the free extremity thereof of the free end of such shroud for selective extension of such shroud from a retracted position to an extended position mating with the airplane contour.
