A guided type fall arrester with a flexible anchor line (in accordance with EN 353-2) is a specially-designed connector which can be used by individuals working at heights to secure themselves from falls. It is used to connect up a user’s safety harness with an anchorage device installed on a building, resp. substructure. A guided type fall arrester with a flexible anchor line is a standard component of a personal protective equipment kit (PPE).

Individual components

This type of connector is based on a guide cable (flexible anchor line), a guided type fall arrester, which often doubles up as a manually-adjustable rope shortener, and an energy absorber. Carabiner hooks are attached to the energy absorber and one end of the guide cable. Lanyards fitted with an energy absorber are often made of fabric which stretches in the case of a fall to minimise the ensuing force, although the amount of stretch is extremely limited. In order to fulfil the requirements resulting from different working environments, these lanyards are available in a range of different lengths.

How to use a guided type fall arrester correctly

The user connects the carabiner hook attached to the guide cable to the anchorage device and then connects the hook attached to the energy absorber to the anchorage eyelet of his/her safety harness. The respective anchorage device may be a single anchorage point for individuals, a roof safety hook or a glider attached to a lifeline or rail safety system. Whilst working, the rope shortener is used to keep the guide cable adjusted to the safest length. Ideally, the connector is adjusted so that the user cannot step out over the precipitous edge. This prevents the user from falling.

Usage in a vertical lifeline system

When used in a vertical lifeline system, the guided type fall arrester is not equipped with a manually-adjustable rope shortener. Instead, the guided type fall arrester glides along the guide cable on its own and follows the movements of the user. If a sudden load is exerted upon the device, as in the case of a fall, for example, the device automatically blocks to catch the person and stop him/her from falling.

Regular inspections

According to the DGUV specifications, guided type fall arresters which are part of a personal fall protection kit must be regularly inspected by a PPE specialist and serviced where required. Irrespective of these regulations, a maximum usage period has been stipulated. Once this period has lapsed, these connectors may no longer be deployed - regardless of their condition - and then need to be replaced.
