I generally don't pay any attention to anything that that glorified backpacker says. He is a hell of a lot greener than most of us when it comes to 4wding. Google how long his first 4wd lasted.Sounds like most of you are of the same opinion as me that the recovery point and chassis support attachment should be strong enough to far exceed the breaking strain of the strap or winch rope. I would rather have something soft break than a hardware component go flying through the air.
@AndrieK, I get what you are saying about a recovery point may deform, but that is or should be an extreme case and yes better that than the chassis torn out, but still better for a soft component to give way first. I remember snatch straps and some winch extension straps used to have indicator stitching that shows a different colour if the strap has bee over stressed stretched and the stitching starts to pull before the strap should break. But I don't see any of them advertise this feature anymore, maybe it was a feature too hard to build in a well controlled fashion during manufacture.
For now I think I will be sticking with the 4.75T shackles to attach to my recovery points at front as the edges are too sharp for a soft shackle. At the rear I use a Reese type hitch receiver and have two extra tow points on the Kaymar bar.
But when I get hold of some more short lengths of Dynema, I will have a go at making myself some simple lanyard type safety straps. Something that is usable in a multiple situations to loop around a strap and attach to a different point to the main recovery point, just as a bit of extra protection. Or even to attach as a loose loop between the join if two snatch straps are used linked together.
After watching Ronny Dahl's video I don't have a lot of faith in the bag type damper things. Might have to investigate other options, such as a dynema lanyard tied to the damper so it can't allow the strap or cable to just pull straight through.
Dont believe in using a bridal strap as it reduces the capacity of the recovery equipment. Whilst I have no formal qualifications. I spent over a decade rigging loads and operating cranes so im very aware of reduced capacity due to the way straps and cables are rigged. It also puts a sideways force on the chassis rails and attempts to pull them together. Straight line pulls are the strongest.
I did the maths years ago to work out how strong the factory hook is on the GU. Its a hell of a lot stronger than most people give them credit. Will have to find where I put it. And post it up sometime. A standard snatch strap will break long before it fails.
I definitely believe that recovery points should be the strongest part of the equation by a large safety factor. Better to have a strap or winch rope fail than a chunk of metal. I always use a weighted winch cable dampener when snatching or winching anyway. I learnt recovery techniques from attending many winch challenges at LCMP and payed a lot of attention. Then went out and practiced what I learnt. My missus is also very capable and understands how to setup recoveries as well.
Must mention that I've never snapped a snatch strap either. I start off slow and work up from there. If the first 2 or 4 efforts dont work I pull the winch cable out.
I believe that most recovery incidents are because they didn't take 5 and assess the situation before taking off like a bull at a gate.
I always follow the same procedure..
Ascertain why the vehicle is stuck.
Remove as much of that obstruction as feasible.
Evaluate methods of recovery.
Remove all unnecessary bystanders to a safe distance including all passengers.
Communicate what I'm doing with all parties.
Recover with the lowest amount of force possible.
