An emergency escape device for a structure comprising a continuous cable in the form of a ladder (37) comprising two separate side supports pinned by rungs (20), said cable being accessible from a sidewall of a structure and being supported by a pulley (5), rungs (20) of the ladder including laterally extending arms (21) having locating members (22) on the free ends thereof, guide rails (25) fixed from a structure beneath the pulley, the guide rails being arranged to accommodate the locating members of the laterally extending arms to prevent deflection of the ladder and operating means (18) for the cable which enables a user requiring access to or descent to stop or restrict movement of the cable as required. The winding speed of the ladder can be controlled by a closed circuit hydraulic system (6). <IMAGE> |
