FALL ARREST DEVICE

摘要

A fall arrest device comprising a body having a rope guide path therethrough defined between a cam and a cooperating abutment. The cam is pivotally mounted on the body about a pivot axis extending perpendicular to the rope guide path. The device is provided with an attachment means for attaching the device to a harness, a rope jamming portion of the cam being arranged to be urged towards the abutment to a rope jamming position to arrest movement of the rope through the rope guide path under the action of a load applied to the attachment means. A rope engaging surface of the rope guide path remote from said rope jamming portion of the cam is adapted to grip the rope when the rope acts thereagainst by virtue of a downward load applied to the attachment means.
