The retractable wire rope fall arresters is one type of personal fall protection systems (EN363). This single leg steel wire rope fall arrest effectively eliminates tripping hazards while the inertia-locking mechanism arrests a fall within inches of activation.

Purpose
etractable fall arresters consist of a drum wound lanyard that automatically locks at the onset of a fall to arrest the fall. Normal movement will not activate the braking mechanism and normal movement is not hindered as the lanyard extends and retracts freely. Should the lanyard receive a sudden pull caused by the event of a fall, the lanyard locks automatically.
Ø The equipment is part of the equipment used for protecting people against falls from a height. The devices avoid violent arrests associated with full body harnesses.
Ø The retractable lanyard greatly reduces the possibility of entanglement on surrounding structures or physical hindrance by its constant yet light tension.
Ø If a fall occurs a speed sensing brake system will activate, stopping the fall and absorbing much of the energy created.
Ø To reduce the shock loading on the body by limiting the distance of the fall.
Ø Freedom of movement is allowable within a much greater area.
CAUTION: In the event of a Fall Arrester being subject to shock loading, as the result of a fall or any other sudden shock, it must be removed from service.
An arrested fall puts a tremendous amount of force on the body and can sometimes cause serious injury. To minimize that force, it is important to keep the fall distance as short as possible. Self-retracting lifelines (SRLs) allow the lifeline to extend and retract as the worker moves. Connecting an SRL to a fall-arrest system will limit the distance a worker can fall. A shorter fall distance reduces the risk of the worker hitting any obstructions below and makes rescuing a suspended worker easier and faster. An SRL can also be used for travel restraint, but only if the unspooled length of the lifeline will prevent the worker from reaching the edge.
