Advice required about chain types and strength capacities.

[mart]

In a company that I used to work at, the lifting ring on a set of chains would have the SWL on it.

I have various single lengths of chain in the garage, and wondered if there was a way to identify (or calculate) the lifting/pulling capacity of them. I would naturally assume that the heavier the link, the stronger it is. But, what if the chain had originally been made for barrier type purposes, as opposed to lifting something?

Any guidance would be appreciated.

I think generally of its a welded link it's no use for lifting/pulling anything remotely heavy. Lift chains are forged iirc. Other than that I don't know, maybe ask a lifting gear company, there's a place in Lancaster I've used.

I would probably not use it for lifting at all unless its stated on the chain. I don't think the size is a giveaway. I've been amazed how big a rating some small chains have, likewise I once used a big chain to tow something and it snapped pinging off in both directions. Luckily noone was standing in the way, they would have been chopped in half!

I'll have a look at the chain links to see if they are forged.

I'm going to be pulling tree stumps out. There can be a lot of tension in the chain. That is my concern.

Nextdoor used to remove a lot of tree stumps, in the end he found a farm jack the best tool for the job

I've used a farmjack for the same, when I couldn't get my Landy winch in I prefer to press a button instead of pumping a handle.
