A personnel escape mechanism (1) for emergency evacuation of a high-rise building (2). An escape support for personnel in the form of harnesses (122) or a protective cage (172) is suspended from a trolley (8), riding on a rail (6) extending externally from the building (2). The escape support is suspended by cable (80) from a constant speed rotationally braked cable payout mechanism (60) mounted in the trolley (8). The support and trolley (8) are impelled to the outside of the building (2) through a frangible wall opening (150), and then lowered to a safe ground location (10) by the braked cable pay-out mechanism (60). In a preferred embodiment of the invention, a steel cage (172) is provided on wheels near window (150) of safety glass. This cage is suspended from a cable (80) wound on a cable drum (74), which is rotationally coupled to a hydraulic pump (92) controlled by a restricted, closed loop flow path (100). The cable drum (74) and pump (92) are mounted in a trolley (8) which rides on an I-beam (6) projecting out of the building (2) through the safety glass. |
