Bow shackle ratings
« on: January 18, 2006, 16:46:21 »
Did another recovery today - had to extract my mate, his Navara (on road tyres) and 16' Ifor car trailer from his waterlogged field - and whilst we were hooking up the Yellowstraps (pukka bits of gear I must say), it dawned on me that my shackles might not be up to the job.

The shackles are stamped "WLL 3/4" - does that mean 3/4 tonne, or am I being dim  :oops:

If they are 3/4 tonne rated, is that enough - or do I need meatier ones ?

Theoretical design capacity is normaly 5 times the Working Load Limit (WLL) for quality lifting shackles.

Your 3/4's would therefore be limited to 3.75Tonne but I still wouldn't like to trust them at that, particularily with kinetic starps, flying shackles can really do some damage . . . . but I think you already know that.

I'd uprate them If I were you . . . . just to be on the safe side  :wink:

I've got some 4 1/2tonne rated shackles.
So buy the above post, that means they are rated to 23 3/4 tonne?
Is that right?

So 3/4's are a bit light-weight...........especially if used on a KERR rope ?
