RETRACTABLE LIFELINE ASSEMBLY

摘要

A retractable lifeline assembly includes a housing having a first portion and a second portion separated by a plate portion having an aperture. The aperture places a first cavity of the first portion in fluid communication with a second cavity of the second portion. A shaft extends through the aperture into the first cavity and the second cavity, and a seal proximate the shaft and the plate portion seals the first cavity from the second cavity. The first portion contains a cable assembly and the second portion contains a brake assembly.
