ABSTRACT:
A life-saving device includes a reel wound with rope or steel wire accommodated within a housing which has a lower portion for supporting the user. The housing has a plurality of connecting rods which, when their position is changed, can alter the pressure exerted by a number of pressure rollers on the rope, so that the rope is drawn out and hence the resistance against the housing is changed. The housing further comprises a pair of handles whereby the ropes can be checked if desired.
