<p>A fall arrest device has a locking cam (13) pivotally mounted on a body part (11) which is engaged with a safety cable (10). A cover (18) is pivotally mounted on the body part (11) to receive loading applied to the device in a direction towards the cable (10), whereupon the cover (18) is pivoted to apply the loading directly to the cam (13), in order to bring the cam (13) into its locking condition with the cable (10). Without this cover action, the applied loading towards the cable (10) may result in the device being maintained in its unlocked condition.</p> |
