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