The fall arresters can be mounted on access ropes (flexible anchoring supports) or on rigid elements positioned above the working area. Both the fall arresters and the flexible or rigid anchoring supports are protective devices against falling from height, components of the working at height systems.
The fall arresters are used along with energy absorbers that have the role of taking over and discharge the kinetic energy resulting from a falling from height.
The mechanism of fall arrest system must act so that the operator cannot fall more than 0,5 m.
There are two major categories of fall arresters:
- guided type fall arresters on anchoring polyamide supports (flexible anchoring supports),
- retractable fall arresters.
