Abstract:
A retracting lifeline system, includes: a housing, a first connector attached to the housing, a lifeline, and a hub to which the lifeline is attached at a first end of the lifeline and around which the lifeline is coiled within the housing. The housing includes an opening through which the lifeline exits the housing. The hub is tensioned to rotate in a first direction to cause retracting of the lifeline and coiling of the lifeline around the hub. The retracting lifeline system further includes a second connector attached to a second end of the lifeline. At least a section of the lifeline has an initial ultimate tensile load of at least 8000 pounds and is abrasion resistant (that is, satisfying the abrasion test requirement set forth in the ANSI/ASSE Z359.13-2009 standard) such that the section of the lifeline is available for tie- back anchoring using the second connector. The section of the lifeline is at least partially retractable within the housing.
