Horizontal Lifeline Systems

Custom and Pre-Engineered Lifeline Systems to Meet Your Application’s Needs

Horizontal Lifeline Systems, also known as HLL systems, are utilized in many of the fall arrest and fall restraint systems. Horizontal lifelines are common fall protection solutions in work areas that lack existing anchor points for personnel tie–off. In simplest form, the horizontal lifeline consists of a cable attached to two or more anchor points on a roof-top, crane runway, bridge or outdoor construction site, or any other elevated work area that poses a fall risk to personnel. A horizontal lifeline can be positioned at the base of the structure (e.g., a roof), overhead (e.g., a gallows style system commonly used for railcar and truck load/unloading applications), or somewhere in-between these points (e.g., a crane rail application).

When used in combination with personal protective equipment, a horizontal lifeline can arrest a fall, limiting the amount of force that is transferred both to the worker and the fall arrest system. This same combination of horizontal lifeline, body harness, and lanyard can also serve as a fall restraint system, limiting the the worker’s ability to move close enough to fall over an unprotected leading edge. The fall restraint and fall arrest properties of horizontal lifelines make the HLL an integral part of many fall protection systems.
