Abseiling aid for rescue operations or sporting purposes has facility wherein rotation of cable pulley is transmitted to braking device, and braking action of braking device acts upon rotation of cable pulley

摘要

The abseiling aid with fall braking has a support frame in which there is a cable pulley, and a braking device consisting of a fluid geared pump, or a fluid piston pump, or a dynamo, or a mechanical friction brake, which are interconnected in such a way that the rotation of the cable pulley is transmitted to the braking device, and the braking action of the braking device acts upon the rotation of the cable pulley.
