Lifeline systems for safe, hassle-free work at heights
Permanent horizontal lifeline systems give workers continuous fall protection while moving across roofs, walls, and overhead structures – without ever disconnecting to relocate a tie-off. XSPlatforms offers two engineered systems: XSLinked, a single-cable lifeline for 1 to 3 users, and LinkedPro, a multi-cable lifeline for up to 6 users that lets workers pass each other safely without disconnecting (the only system on the market with this capability at a single anchor point). Both are tested and certified to EN795:2021 Type D, OSHA 1910/1926 Subpart M, ANSI Z359.6, and CSA Z259/16.
What is a horizontal lifeline system?
A horizontal lifeline system (HLL) is a permanent or temporary cable installed parallel to a working surface that gives workers continuous fall protection while moving laterally at height. The cable runs through multiple anchor points along its span, and the worker connects to it via a harness, lanyard, and slider that travels with them. Horizontal lifelines are used on roof edges, walls, overhead beams, and ceilings – any work area where the alternative would be repeatedly relocating a single tie-off or working at height with no protection. A horizontal lifeline must be engineered for the specific installation: span length, user count, anchor substrate, and fall clearance all change the system design.
About our horizontal lifeline systems
XSPlatforms Horizontal Lifeline Systems are engineered, tested and certified for permanent installation on roof, wall, and overhead structures. Each system is designed by a qualified person to meet site-specific load, deflection and fall-clearance requirements, in line with ANSI Z359.6 and OSHA 1926.502 which require horizontal lifelines to be engineered installations rather than off-the-shelf assemblies.
With a Horizontal Lifeline (HLL) System, the worker wears a full-body harness connected by a shock-absorbing lanyard to a permanent steel cable that runs through multiple anchor points secured to the structure. The cable typically follows the roof edge or work path, allowing the worker to move laterally while remaining tied off. A slider (also called a runner) attaches the lanyard to the cable and travels with the worker – including over corners and bends – so a tie-off relocation is never required. In a fall, the energy-absorbing components, the cable tension, and the multiple anchor points share the arrest forces, keeping the load on the worker below the OSHA 1,800 lb (8 kN) limit.
Our Horizontal Lifeline systems can be installed on nearly any type of roof, wall, or ceiling, helping to ensure safe and efficient work at heights.
Compliant with international fall protection standards
Permanent vs temporary horizontal lifelines
XSPlatforms specialises in permanent horizontal lifeline systems – cable installations engineered to remain in place for the working life of the structure (typically 25+ years). Permanent systems are the right choice when a roof, wall or overhead work area requires recurring access for maintenance, inspection, cleaning, or HVAC service. Temporary horizontal lifelines (often rope-based) are designed for short-duration construction work where the access need ends with the project. Permanent systems use steel cable, certified anchors, and engineered components; temporary systems are typically rope-based and re-deployed across job sites. If the same building needs access more than once a year, the lifecycle cost of a permanent system is generally lower than repeated temporary installs – and the engineering documentation transfers with the asset rather than the contractor.
SINGLE- AND MULTIPLE LIFELINE SYSTEMS
XSPlatforms offers two horizontal lifeline systems engineered for different user counts and traffic patterns: XSLinked (single-cable, 1 to 3 users) and LinkedPro (multi-cable, up to 6 users). Both share the same XSSlider runner, which travels through corners and bends without manual disconnection. The choice between them is driven by the number of simultaneous users on the system and how often workers need to pass each other – LinkedPro is the only horizontal lifeline that lets multiple workers pass at a single anchor point without disconnecting from the system.
LINKEDPRO
LinkedPro consists of multiple lifelines. This means that multiple workers can be attached to the system, and can pass other used without disconnecting from their lifeline. The multiple horizontal lifeline solution can be used by a maximum of six users and is especially useful for work areas with high traffic.
Safe Passing Without Disconnecting:
- Up to three lines can be attached at a single anchor point on the LinkedPro system.
- Users can move safely and easily while connected.
User-Friendly and Cost-Effective:
- More users can utilize one system with fewer fall protection resources.
- Quick installation methods save costs.
A Revolutionary System:
- The only system allowing multiple users to share the same lifeline path safely.
- Combining LinkedPro with XSPoint access points enhances user safety by ensuring connections only occur in safe zones, minimizing hazardous situations.
XSLINKED

Components of a horizontal lifeline system
An XSPlatforms horizontal lifeline system has six engineered components that work together:
(1) End anchors – the cable termination points carrying full system load;
(2) Intermediate anchors – support points along the span that limit cable sag and keep deflection within the design limit;
(3) Steel cable – typically 8 mm or 10 mm stainless or galvanised cable, sized for the system load;
(4) Energy absorber – integrated at one or both ends to limit peak fall arrest forces;
(5) Tensioner – sets and maintains correct cable tension;
(6) Slider (XSSlider) – the runner that connects the worker’s lanyard to the cable and travels through corners and bends without manual disconnection.
The XSPoint access point lets workers connect or disconnect only in safe zones, eliminating the most common procedural error in fall protection.
HOW TO CHOOSE THE RIGHT LIFELINE SYSTEM?
Choosing the right system protects workers at height
LinkedPro solution developed for a project in Boston, Massachusetts.
When selecting the appropriate horizontal lifeline (HLL) system, such as our XSLinked or LinkedPro solutions, it’s essential to evaluate several key factors based on your work environment and requirements. In this guide we want to show you which factors you need to consider.
Before you start with any project, always evaluate the conditions of a work area. Is this work area indoor or oudoor?Environmental factors such as wind, rain, and temperature extremes can affect system durability and performance. Additionally, assess potential hazards like electrical risks or deviating conditions on a roof or industrial area, which may lead to a custom made solution.
What tasks need to be performed when connected to the horizontal lifeline? For jobs that require a higher mobility, systems with longer spans can be the right choice. Jobs with a wall- or overhead solution may require a much more sturdy solution or rigid rail system for example.
Determine the cable length and layout: a single straight run, a multi-corner perimeter, or a system that spans multiple planes (for example a roof that transitions to an overhead beam). Layout affects anchor spacing, total cable sag under load, and minimum required fall clearance. Spans over 60 ft (18 m) typically require intermediate anchors to keep deflection within the manufacturer’s design limit.
With ODIN, you can precisely calculate the loads involved in horizontal lifeline systems, as well as the lifeline deflection and minimum clearance required for safe fall arrest. This tool ensures that lifeline systems meet applicable standards without the need for complex manual calculations, reducing injury risk in the event of a fall. Check out more information about ODIN Lifeline calculation Tool here.
Ensure the HLL system can safely accommodate the number of users at any given time. Take into account the combined weight of all users and their equipment to ensure safety. For example, if more users need to be working on the same system, at the same time a LinkedPro system could be a much better solution.
The HLL system must work seamlessly with personal fall arrest systems (PFAS) and other PPE. Ensuring compatibility enhances overall safety and effectiveness. Our PPE systems are tested thoroughly and are used with all type of lifeline systems.
Calculate the required fall clearance below the working surface: lanyard length + energy-absorber elongation + lifeline cable sag + worker height + safety margin. As a baseline, a 6 ft (1.8 m) shock-absorbing lanyard typically requires 18 to 22 ft (5.5 to 6.7 m) of clearance, though this varies with span length and user count. For low-clearance situations, a rigid XSRail system limits sag to near-zero and is the right choice. The ODIN Lifeline Calculation Tool models the actual deflection and minimum clearance for your specific geometry.
SELECT THE RIGHT SOLUTION
By carefully considering these factors, you can select the right horizontal lifeline solution from XSPlatforms to ensure the highest level of safety for workers at height.

FAQ: HORIZONTAL LIFELINE SYSTEMS
In this FAQ section, we address some of the most common questions about Horizontal Lifeline systems (HLL), their operation, benefits, and safety standards. Whether you’re new to fall protection systems or looking to enhance your knowledge, these answers will help you understand how lifelines work and their importance in ensuring worker safety at heights.
A horizontal lifeline (HLL) connects a worker’s harness, via a shock-absorbing lanyard, to a permanent steel cable that runs through multiple anchor points along the structure. A slider attached to the lanyard travels with the worker so the connection is never broken during lateral movement. If a fall occurs, the energy-absorbing components, cable tension, and multiple anchor points share the arrest forces, keeping the load on the worker below the OSHA 1,800 lb (8 kN) limit and minimising structural damage at the anchor points.
Regular inspections of a Horizontal Lifeline are crucial for safety. They should be evaluated at least annually by a qualified individual. It is also advisable to inspect the system before each use to identify any potential damage or wear.
Using a Horizontal Lifeline offers numerous advantages, including improved safety for workers at heights, increased freedom of movement, and compliance with occupational safety regulations. Additionally, they facilitate simultaneous connections for multiple users, promoting teamwork and efficiency.
Yes. In the U.S., horizontal lifelines must comply with OSHA 1910 Subpart I (general industry), OSHA 1926 Subpart M (construction), and the design specification ANSI Z359.6. Internationally, the leading standards are EN 795:2021 Type D and CEN/TS 16415:2013 Type C (Europe), CSA Z259/16 (Canada), and AS/NZS 1891.2 + AS/NZS 5532 (Australia/New Zealand). All XSPlatforms horizontal lifeline systems are tested and certified to these standards. OSHA additionally requires the system to limit fall arrest forces on the worker to 1,800 lb (8 kN) and to be designed and installed under the supervision of a qualified person.
It depends on the system. The XSLinked single-cable system supports 1 to 3 users simultaneously. The LinkedPro multi-cable system supports up to 6 users at once and lets workers pass each other safely without disconnecting from the lifeline – the only system on the market with this capability at a single anchor point. Adding more users requires recalculating fall clearance and anchor loads (combined worker + equipment weight), which the ODIN tool handles automatically.
