ABSTRACT:
Escape device that comprises a sliding box worn by each escaping person, such that the escape device is combined with an escape cable. The sliding box comprises a supporting structure; a driven wheel supported in the structure for rotation, and adapted to be in engagement with the escape cable and to be driven thereby into rotation. The rotary speed correspond to the speed of the motion of the sliding box relative to the escape cable, and therefore, corresponds to the speed of descent of the escaping person; means for measuring the rotary speed of the driven wheel and therefore, the speed of descent of the escaping person; and braking means, for slowing the rotation of the driven wheel, and therefore the speed of descent of the escaping person, whenever it is required to maintain the speed of descent within predetermined limits.
