Abstract

The device is for evacuating persons in danger and has a housing, preferably rectangular, inside which a rope (6) is wound onto a drum (2). One of the drum flanges has peripheral teeth meshing with a pinion driving a gear train (12, 13) inside a compartment sealed from the housing and runing in an oil bath. The gears drive the oil through a return passage (15) whose cross section is adjustable (16). The upper pinion of the gear train can be keyed to the shaft carrying the pinion meshing with the drum teeth. The opening through which the rope emerges from the housing can be covered by strong rubber lips.
