Ring set ups

[Ledburyjosh]

Does anyone use a ring in the following orientation? 

Theory being the rope can't get pinched between. The tree and ring

Your'e running the rigging rope on the outside rather than through the ring?

That's the idea yes

Bigger bend radius I guess....

Yeah, the off-roaders do this. The latest thing is using rings for snatch blocks with soft shackles. It turns the ring into to a pulley. However, they are working at really slow speeds.

 

In a tree setup, there would be a couple of things to consider. The sling normally cinches around the ring, held in place by the flanges. It sits fairly tight, so the ring cannot pop out of the sling. The rigging slides through the hole. Most of the ware is on the hole.

 

With your setup, the ring is going to be rotating (maybe). The sling is going to be holding a rotating ring, so the sling will experience ware. Normally with a pulley, the shieve is rotating on a bushing, and it's that bushing that takes the brunt of the ware. Your sling will be taking the place of a bushing.

 

Also, metal snatch blocks have side plates to stop the line from jumping out of the groove and off the block. There is nothing to stop your line from leaving the groove, except gravity and tension. If it does somehow jump the groove, it will fall and be caught by the sling. Rope on rope friction, under a running load, your sling will be history within seconds.

 

This is fine for winching a car out of a mud hole. Controlled, slow force, easy to monitor.

1% advantage of not pinching rope

50% disadvantage of possibility of rigging rope jumping into ring sling rope

99% disadvantage of constantly worrying about the above

 

Admirable attempt to optimise but a problemless solution IMO. Rings work fine in normal configuration.

It would work great for winching purposes though, with a Massadam rope puller. Or even just hand pulling. Multiple uses for one piece of gear.

Yup. And ita for that reason I'm yet to try it..

gents, that rope on ring combo is used( at least by the manufacturer Giorgio Fiori and me )for double line rigging...never had issues like that...might be cause I never negative rigged with 2 ropes, but do it with 2 separate rings

Do you negative rig onto the ring in this orientation with a single line at all?

Or just stick to that standard way?
