Self Retracting Lifelines (SRLs)

Self Retracting Lifelines (SRLs)


Product Overview

Self-retracting lifelines (SRLs) are critical safety devices commonly used in industries where workers are exposed to fall hazards, such as construction, mining, and maintenance. They provide a more dynamic and flexible means of fall protection compared to traditional lanyards.

An SRL consists of a retractable cable or webbing wound on a spring-loaded drum inside a durable housing. One end connects to the worker's harness, and the other end attaches to an anchor point. Unlike static lanyards, SRLs automatically retract excess line as the worker moves, maintaining tension in the line. If a fall occurs, the SRL locks up within seconds, limiting the fall distance and reducing the impact forces on the wearer's body. This rapid braking action is crucial in preventing serious injuries.

SRLs offer several advantages, including increased mobility, reduced fall distance, and ease of use. They are available in various configurations, such as personal SRLs for individual use and larger ones designed for overhead horizontal lifelines or vertical climbing systems. Regular inspection, maintenance, and adherence to safety guidelines are essential to ensure the reliability and effectiveness of self-retracting lifelines in safeguarding workers at height.

Whether your application requires single or twin-leg configurations, mounting to an overhead anchor, leading edge applications or for connection directly to the harness, there are numerous models available for nearly every application. Our shared goal is to bring you home safely at the end of the workday and we want to make sure you’re comfortable so you can get the job done.

The 3M™ DBI-SALA® Sealed-Blok™ Self-Retracting Lifeline (SRL) incorporates a patented concept that helps separate components, such as the motor spring and brake, from foreign elements such as grease, moisture, and dirt. The 3M™ DBI-SALA® Sealed-Blok™ Self-Retracting Lifeline is IP-69K rated to provide protection against ingress of dust, high tempeatures, and high pressure water, for use in extreme environmental conditions. These lifelines are available in Overhead, Retrieval, and RSQ / Rescue SRL configurations.

When it comes to confined space and entry rescue, the 3M™ DBI-SALA® Sealed-Blok™ Self-Retracting Lifeline (SRL) is essential; it operates quickly and efficiently in the toughest environments. The 3M™ DBI-SALA® Sealed-Blok™ Self-Retracting Lifeline is one of the most critical parts of a rescue system as it provides the means to retrieve an incapacitated worker to safety. The SRL’s lifeline is designed to extend as the user moves away and retracts automatically, enabling the user to move around within a recommended working area at normal speeds. Should a fall occur, the SRL’s internal centrifugal energy absorption system will activate, stopping the fall and reducing the forces imposed on the user to safe levels.
