Portable Horizontal Rail Fall Protection

safe and compliant temporary overhead fall arrest protection

Flexible Lifeline Systems portable rail solutions provide safe and compliant temporary overhead fall arrest protection when space is limited or there is low overhead clearance. Unlike traditional cable horizontal lifeline systems, rigid rail systems eliminate sag distance and reduces overall fall clearance from the anchor point to the ground.

Ideal for working on transport vehicles, aircraft, heavy construction equipment, these systems can be equipped with an entrance platform, stairs, ladders and more to provide ground-up fall protection. FLS fall protection specialists are ready to work with you on selecting the right products for even the most challenging applications contact a fall protection specialist now.



Horizontal Rail Systems are designed to be moved manually or with the use of a tow bar and service vehicle. These systems can be easily transported to locations where overhead fall protection is needed and not otherwise available.



Horizontal Rail Systems are rated for indoor and outdoor use, and can be outfitted for multiple environments, applications or terrain providing reliable fall protection for even the most unique work environments.



Lightweight frames and swivel wheels allow the system to easily be transported and positioned wherever it is needed.

OSHA REGULATIONS FOR Portable Horizontal Rail Systems

1910.140(12) Anchors used to attach to personal fall protection equipment must be independent of any anchorage used to suspend employees or platforms on which employees work. Anchorages used to attach to personal fall protection equipment on mobile work platforms on powered industrial trucks must be attached to an overhead member of the platform, at a point located above and near the center of the platform.


1910.140 Personal Fall Arrest Systems: The employer must ensure that each personal fall protection system used must comply with the requirements in this section:

  1. Limit the maximum arresting force on the employee to 1,800 pounds; 1910.140(d)(1)
  2. Bring the employee to a complete stop and limit the maximum deceleration distance the employee travels to 3.5 feet; 1910.140(d)(1)
  3. Have sufficient strength to withstand twice the potential impact energy of the employee free falling a distance of 6 feet, or the free fall distance permitted by the system; and… 1910.140(d)(1)
  4. Sustain the employee within the system/strap configuration without making contact with the employee’s neck and chin area. 1910.140(d)(1)


In the absence of a specific requirement for Inspection, OSHA Sec 5.a.1 becomes default: OSHA Sec 5.a.1 (a) Each employer – (1) shall furnish to each of his employees employment and a place of employment which are free from recognized hazards that are causing or are likely to cause death or serious physical harm to his employees; 29 USC 654 (2) shall comply with occupational safety and health standards promulgated under this Act. (b) Each employee shall comply with occupational safety and health standards and all rules, regulations, and orders issued pursuant to this Act which are applicable to his own actions and conduct.

Following manufacturer’s requirements is considered a reasonable effort to satisfy this general rule and employee responsibility. Flexible Lifeline Systems follows the requirements set by the manufacturer of the components that are used to build your system. Additionally, ANSI Standards ANSI/ASSE Z359.2 Z.359.6-2016 9.2, while not codified as law, are considered to be “best practices” and often required by many companies – insurance, banking, etc., to provide coverage such as worker compensation or professional insurance, or to assess capital asset values. These standards speak directly to importance of regular inspection of fall protection systems.
