Recovery strap rating - Land Rovers Only

AZROVER · 02-20-2007, 07:39 PM

I just bought a strap off ebay for pretty cheap but can someone tell me what the rating numbers mean in regards to what I'll be able to do with it? The two numbers are a.b.s( assembly break strength) 19,800lbs; and w.l.l(working load limit) 6,600lbs. I'd appreciate knowing what this limits me too before I go yanking on a discovery with it. Thanks-Hank.

It is the maximum load in pounds which should ever be applied to a chain or strap when the load is uniformly applied in direct tension to a straight length. The assembly break strength is the tested limit as which on a uniform pull it will rip apart. You can very easily exceed the WLL of that strap if you yank on it- but for giving a gentle pull, it is likely ok... just don't go yanking the hell out of it like many people do. There are inertial straps which are made to stretch and yank- those are a whole different thing.

Snatch straps are usually only listed at their breaking point. That is, you have a 8,000kg or 20,000lb strap. The WLL applies if it is being used in a commercial environment.

WLL is a rating for constant tension, breaking point is where it comes apart (usually 3x or so the WLL). WLL applies in any environment, it's just required to be marked on any piece of commercial equipment.

Safe working load is usually set at around 1/3 of the breaking point of a unit. Things like shackles are rated at SWL. That is why you can use a 8 ton snatch strap on a 3.25 ton shackle. The difference is simply the safety margin built into commercial equipment.

I think I get it now. I figured it was an inertial strap but I really don't do that much recovery anyway, just wanted the piece of mind when I head off road. thanks for the replies.

Just be careful doing recoveries- it is the one part of offroading where the vast majority of people THINK they are experts but are far from it. I'm simply astounded more people aren't killed or injured after watching so many dangerous and wreckless recoveries.
