Dual-Class Self-Retracting Lifelines Meet Both Class A and Class B Guidelines
Meet the Hybrid Hog, the new Dual Class Self-Retracting Lifeline that gives you the advantages of both Class A and Class B retractables, all in one. The Hybrid Hog comes in both a 20′ Dual Class SRL and a 30′ Dual Class SRL.
Self-retracting lifelines (SRLs) are a staple piece of personal fall protection equipment used to keep workers safe when working at heights in a wide range of industries. SRLs generally come in two versions—Class A and Class B—established by ANSI standard Z359.14-2012. Both types of SRLs limit the maximum peak arresting force to 1,800 pounds as required by OSHA (OSHA 1926.500 subpart M) when worn with a body harness, but the two classes differ on two key dimensions: maximum arrest distance and average arresting force.
- Class A SRLs are defined as devices that provide a maximum arrest distance of 24” (610mm) and an average arresting force not exceeding 1350 lbs (6kN). This class of SRLs is designed to arrest a falling worker very quickly, and is typically used in areas where fall clearance is limited. Think of it like slamming on the brakes in your car when you need to stop immediately—it may be a little jarring, but what matters is stopping before you hit anything.
- Class B SRLs are devices that provide a maximum arrest distance of 54” (1372mm) and an average arresting force not exceeding 900 lbs. (4kN). This type of SRL also stops a falling worker safely but arrests the fall a bit more gently. Slowing to a stop over a longer distance makes the stop less jarring. This is why you gradually slow to a stop when you’re driving up to an intersection instead of slamming on the brakes—it’s a lot more comfortable if you can afford to slow down gradually.
The new Hybrid Hog from Malta Dynamics combines the advantages of each class into a single device that meets the standards for both classes. The Hybrid Hog offers a maximum arrest distance of just 24 inches to qualify as Class A while also limiting the average arresting force to 900 lbs. to qualify as Class B. It’s the best of both worlds in one durable, affordable SRL.
