Abstract

An abseiling device includes an annular spool with an inner surface, the spool being rotatable around a central axis. The spool includes an annular gear around its periphery with gear teeth facing the central axis. A line is wound around the spool, with one end fixed to the spool and the other end having an attachment mechanism. The device also has a shaft which is co-axial with the central axis and a centrifugal brake attached to the shaft. The centrifugal brake includes brake pads for applying a breaking force to the spool. The device also has a brake gear attached to the shaft, the brake gear being rotatable with the shaft, and a compound gear. The compound gear includes a first gear for engaging with the brake gear and a second gear for engaging with the annular gear. The first gear has a greater number of teeth than the second gear. When the spool is at rest the brake pad extends around over 80% of the circumference of the inner surface of the spool.
