What is your usage cycle like that you are using up pulley blocks that fast?Interesting thread
I know Red Winches well - they are based about 20 miles down the road. I have written a number of articles about them and their products. They build good stuff. I trust them
I've just been given one of their Rings to test, along with a demo soft shackle from Ruftracks. I'm open minded about it.
I've been using synthetic line, for winching, for about 20 years now. I still use Fibre Core Steel rope for certain things. I no longer compete, but I teach winching and I'm an assessor for a truly internationally accepted winching qualification. I also recover plant, move timber, salvage and recover vehicles.
In the old days, I would wear out a Superwinch Pulley Block (it's not a snatch block) in a six month. So I moved over to TJM (with grease-able bush). They would last, at best a couple of years. Then I bought a roller bearing unit from a German lifting company. That's ten years old, this year.
So I use kit.
I don't use high speed winches. I prefer pulling power and efficiency. My weapon of choice at the moment is a G10, with a Bow2 and upgraded bearings
I can see a use for the Ring. It's light, simple and easy to use with gloves on (remember only a fool doesn't wear gloves). Metcalf has a point about it's inability to snag the synthetic line (which cheap or worn pulley blocks will do on a regular basis). I shall include it in my teaching. I'm going to knock up a version of Metcalf's block and strap concept, within the next few days. It makes sense - although I might use a block of cold pour polyurethane...
So to conclude, I think this clever and simple development has a place in our world, although there will undoubtedly be teething problems and the odd 'nay sayer'
Not as heavy as you'd think. But many times as much as most that are used for recovery. To be fair, the Superwinch/King One pulley blocks are cheap; in fact very cheap. Most come out of the box with too much play between the shears. They all need some adjustment. I'd estimate maybe 1.5 to 2k times a year, including double line and angle changes (but that's a low estimate). The Cheap pulley blocks are rated at 4.5 Tonnes SWL, whereas the TJM units are 7.5 tonnes SWL and the nice shiny Teutonic loveliness is rated at 10 tonnes SWL. I've also got an 8 Tonne Black Rat unit that has lasted as long as the German unit (Heinrich I think); I'm particularly fond of this one as it doesn't use a cir-clip to hold it together, rather an 'R' clip, so it's easy to pull apart and rebuild...What is your usage cycle like that you are using up pulley blocks that fast?
Good stuff. Great price point.There are definitely opinions both ways on these, but I love them so much I started making them. I worked with a small machine shop here in South Carolina, USA, and made another run of recovery rings. This time in orange. If anyone wants one, message me or check them out on ebay..... Yes I ship all over the world and Yes I have had these tested to determine the strength rating.
View attachment 584989A win win situation for everyone! If you have any doubts, do a google search on "recovery ring system". There are many useful videos and a lot of information on how to use them.www.ebay.com
I make and sell solid recovery ring in the USA. PM me, or see the ebay link in my signature.Any dealers in US?
The heat issue was discussed earlier in this thread and it is just not possible to get it hot enough to do damage.I would think the soft shackle or rope used to attach the ring to your anchor would get very warm do to the friction. Would that heat weaken and cause excessive wear on that soft shackle or rope? Wouldn't the knot in the soft shackle or rope also be a weak point?
I found this interesting:
Stoopid speel cheeker!I guess the ASME proof-reader was at lunch when this was relieved (sic):
"ASME B30.26 has the following statement regarding screw pin shackles:
The screw pin threads shall be fully engaged and tight and the shoulder should be in contact with the shackle body.
Thus, contrary to popular believe, you should never back off the screw pin before use. The shackle pin should be a minimum of hand tight before the lift begins."
I don't have much recovery experience and I'm trying to educate myself, so sorry if this is a dumb question. Regarding the frame at 10:29 that you posted, isn't his point in saying, "don't do this" the concern of adding weight and potential projectiles to the system?
He seems to mean within 4WD recovery, but his emphasis seems to imply it's not safe. It is generally safe to link shackles like that within a WLL standpoint, as Crosby's discussion states.I don't have much recovery experience and I'm trying to educate myself, so sorry if this is a dumb question.
