Horizontal Rail Lifelines can be installed from overhead to near ground elevations. Rail systems offer various design options for an enclosed track, open track and overhead traveling bridge. The enclosed track features single, dual and triple tracks permitting users to bypass one another while staying connected to the system. When bypass is not required, an open track is a cost-effective option which operates similarly to a beam and trolley system. The traveling bridge provides unencumbered movement allowing the trolley to follow the user in any direction which minimizes potential swing fall hazards.
