Swaged Tensioner
The Groxx GRXRLSX01 is a sophisticated vertical rail slider engineered specifically for integration with rigid vertical rail lifeline systems. Designed for use on ladders, pylons, and wind turbine internals, this slider functions as a guided-type fall arrester, providing workers with hands-free vertical mobility while maintaining an instantaneous lock-on capability in the event of a descent acceleration.
Guided-Type Fall Arrest: The GRXRLSX01 is designed to glide effortlessly along the vertical rail profile during normal ascent and descent. Its internal cam mechanism is gravity-biased to remain open during steady movement but reacts immediately to gravitational acceleration.
Bi-Directional Locking: Engineered with a specialized locking pawl that engages with the rail profile. In the event of a fall, the slider locks within centimeters, significantly reducing the total fall distance compared to flexible cable systems.
Anti-Inversion Logic: The slider incorporates a “fail-safe” orientation feature that prevents the device from being installed upside down on the rail, eliminating a common cause of vertical system failure.
Integrated Shock Dissipation: While the rail is rigid, the GRXRLSX01 is designed to interface with an energy-absorbing lanyard to cap the Maximum Arrest Force (MAF) below the critical $6\text{ kN}$ threshold.

Stainless Steel Construction: Manufactured from high-grade stainless steel to ensure the locking cams and springs remain free of corrosion, which is vital for the mechanical timing of the fall arrest function.
Ergonomic Release: Features a manual bypass or release trigger that allows the user to easily remove or attach the slider at designated “gate” sections of the vertical rail.
Smooth Transit: Internal low-friction bushings are utilized to ensure the slider does not “chatter” or hang up during climbing, reducing user fatigue.
The GRXRLSX01 is engineered and certified according to the most stringent European standards for vertical fall protection:
EN 353-1:2014+A1:2017: This is the primary regulation for Guided type fall arresters including a rigid anchor line. The GRXRLSX01 meets the updated requirements for “function testing” under cold, hot, and sandy conditions, ensuring the locking mechanism works in all environments.
PPE Regulation (EU) 2016/425: Complies with the essential health and safety requirements for Category III personal protective equipment.
Lateral Pull Test: Meets the specific EN 353-1 requirements for lateral loading, ensuring the slider stays captured by the rail even if the user falls sideways or away from the ladder.
The GRXRLSX01 provides a level of security and comfort that cable-based vertical lifelines cannot match. By utilizing a rigid track, the slider eliminates “cable whip” and the elastic “bounce” associated with fall arrests on wire rope, providing the climber with a much higher degree of actual and perceived safety during high-elevation transitions.
