Abstract

A fall arrest device, such as a self-retracting lanyard (or lifeline) including: a rotatable drum for winding a lifeline; and a brake arrangement comprising a rotatable brake body arranged to rotate in response to rotation of the drum; wherein rotation of the rotatable brake body applies a braking force to the drum as the lifeline is being retracted onto the drum.

Description

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS [0002] This application claims priority to UK Patent Application No. 1619805.3, filed 23 November 2016, entitled "Self-Retracting Lifeline Fall Arrest Device", the entire contents of which are incorporated herein by reference. technical field [0003] The present invention relates generally to a fall arrest system and fall arrest apparatus, and in particular to a braking device for a fall arrest apparatus, such as a self-retracting lanyard.
