Thread: Snatch Block v Snatch Ring

Although it’s been some time since I’ve used my PTO but I generally set up 2:1

Why 2:1, well my PTO has a sheer pin and would be an absolute pain to change during a recovery.

I can make up for loss of speed when required by using gearbox and accelerator

Hence i never leave home without snatch block.

Just thinking I should investigate the material and design of the sheer pin, considering I’ve owned it for 15 years

- pretty sure it brass
- not sure if it parallel or tapered.

Blind Freddy can guess that there would be more friction developed using the snatch ring because under load it wont rotate as freely as a snatch block.
Friction = Heat and that is the LAST thing you need using synthetic rope and not to mention the extra wear and tear on your winch itself due to the extra load on it using these rings.
Think of fishing rods, Heavy duty fishing rods have "Roller" line guides on them NOT the usual ceramic rings found on most fishing rods

As a rule of thumb NEVER substitute a sheer pin for something stronger, They are designed to fail for a Very good reason.
Think electrical fuses and why you never exceed a recommended ampage with these

Thanks and yep I’m flying a little blind...as I’ve never actually picked up snatch ring. Weight and size got me interested and decided to research.

Your point of heat is a good point hence asking members that have actually used both and can give real feedback.

Given I’m more likely to use a snatch block when winching maybe I’ll stick with the tradition type.

Yes totally agree....I should really track down replacement pins or investigate a torque limiter of some sort.

They are usually brass.

If you can’t get one,a good fitter will be able to turn one up on a lathe.
Using yours as a sample.

A snatch block gives you a mechanical advantage because it is a pully, There is bugger all mechanical advantage when using a snatch ring.
IF a snatch ring is a better option then why were pulleys invented instead of just throwing a rope over a stick??

Yes, thinking they won’t be off the shelf.

Would you know if they are tapered? I’m guessing not.
