Definitions

  • This disclosure generally relates to safety devices.
  • the disclosure relates to a device for storing a retrieval cord of a fall-arrest system.
  • Fall-arrest devices include a base unit that is mounted to a structure and a life line that is connected at one end to a rotatable spool within the base unit.
  • the life line is releasably fixable at a harness-end to a harness that is worn by the worker.
  • the base unit is often mounted overhead of the area where the worker is working. Should the worker fall, a brake within the base unit stops the life line from further unwinding from the base unit, thereby reducing the distance that the worker can fall.

Abstract

L'invention concerne un dispositif de stockage destiné à être utilisé avec un dispositif antichute auto-rétractable (SRD) qui protège les travailleurs travaillant en hauteur. Les SRD sont souvent montés au-dessus d'une zone de travail , ce qui peut compliquer la récupération par un opérateur du cordon de sécurité lorsque le moment est venu d'utiliser le SRD avant de monter jusqu'au lieu de travail en hauteur. Un câble de récupération peut être relié au cordon de sécurité et utilisé pour tirer le cordon de sécurité du SRD. Cependant, pendant que l'opérateur travaille en hauteur, le câble de récupération n'est pas utilisé et est souvent laissé en vrac dans la zone au-dessous du SRD, ce qui constitue un risque pour la sécurité. Le dispositif de stockage est destiné à recueillir et à stocker le câble de récupération qui est utilisé avec un SRD pendant que l'opérateur travaille en hauteur.
