Dual-Class Self-Retracting Devices Meet Both Class A and Class B Guidelines

Malta Dynamics introduces 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. 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 distanceand average arresting force.

Class A SRLs are defined as devices that provide a maximum arrest distance of 24 inches (610 mm) and an average arresting force not exceeding 1350 pounds (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 inches (1372 mm) and an average arresting force not exceeding 900 pounds (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 alsolimiting the average arresting force to 900 pounds to qualify as Class B.

Lifeline Works Like a Seatbelt

Latchways has introduced the next-generation ManSafe Mini Self-Retracting Lifeline (SRL) to its portfolio.

Latchways has introduced the next-generation ManSafe Mini Self-Retracting Lifeline (SRL) to its portfolio. Smaller and lighter than its predecessor, the product features a patented, frictionless braking system and multiple spring radial energy-absorbing technology. Weighing a little more than 2 pounds when fitted with a double-locking snap hook, the mini is 6 feet in length. It can be used with a forged-steel snaphook, carabiner/hook and aluminum scaffolding hook. SRLs work in a similar manner to a seatbelt, permitting normal movement to facilitate work but in the event of a sudden fall, the mechanism locks, preventing any further movement. The SRL accommodates users from 132 to 309 pounds, including tools.
