Snatch Block v Snatch Ring

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.

Some were even ribbed on purpose so the weakest part was vulnerable to letting go. Brass pin that one & a LR Part for the Capstan Winch.

Apparently these are very scarce but if you can fine a good one then, as Paul said.
I don't know for sure but they would be rated for the equipment in use imho so one for a Capstan winch would probably be rated differently for other applications.

hmmm following another earlier thread, I've just realised I carry my snatch block everywhere for no reason.

I have no rope to use it with, I carried a good length of winding rope for ages kept in perfect condition and some member of this forum has it now.

IF a snatch ring is a better option then why were pulleys invented instead of just throwing a rope over a stick??[bigwhistle]

Dead eyes are a block of usually lignum vitae with two or 3 holes and used to give a mechanical advantage and are still used today .With a snatch ring you still get your 2-1 advantage depending on how rigged with the difference in friction negligible also the heat measured in heavy winching is not a concern also
