    Default Where to source 10 ton load rated chain?

    Hi all,

    Trying to source some 10 ton load rated chain with some sort of adjuster so I can vary the length. This will be used with a 10 Ton Hydraulic pull back ram. https://www.ebay.com.au/itm/Hydrauli...oAAOSw41tZ4dfc

    Where would be the best place to source this from?

    Thanks

    10 tonne lifting capacity chain is going to be some hefty stuff. Beaver says Grade 80 lifting chain 16mm has a capacity of only 8 tonne, and 11 metres of that weighs 100kg.



    For a shortener, buy two hooks and join them together. I have that for some light 7mm chain I use for lifting.

    You will have to go to 20 mm chain in grade 80 which will give you a WLL of 12.5 tonnes, but if you use grade 100 chain, 16mm has a WLL of 10 tonnes. It would be interesting to see the cost comparison, but there would be a significant weight saving if using grade 100 chain for sure. I would use grab hooks to shorten the chain, as with shortening clutches it is easy to have the chain inserted in the wrong way, which can lead to some very nasty surprises, especially with anything approaching 10 tonnes load involved.
    Below is a chart of grade 100 chain capacities and specs

    Is that only on those slings that use what is properly known as a shortening clutch? If you put the chain in upside down you pull from the top of the clutch rather then the bottom?

    The chain slings I deal with pretty much only look like this. I did not think there was any wrong way to put the chain i them.

    You are correct Richard, if you use a grab hook to shorten chain, there is no "wrong" way to reeve the chain. For those not sure what a grab hook is, the one shown here is a pin lock version, where the pin secures it to the end link of the chain, and in turn the pin is secured with 2 roll pins. Grab hooks are also available with an eye which would allow a chain to be attached with a hammerlock.
    In earlier times grab hooks didn't have the little projecting bump in the bight of the hook, and the chains WLL was derated by a factor of 0.7 IIRC, so shortening clutches which didn't derate the chain were often preferred. The trouble with them was that you had to be extra careful not to put the chain in them so that the load would be taken from the top, because if that was done, the chain would often tip out and the load would drop until you ran out of chain. When they modified the grab hooks with the little bumps, the chain no longer had to be derated. For the sake of completeness, here is a picture of a shortening clutch.
    It seems that time has marched on since I worked as a rigger, and now shortening clutches have a locking mechanism to prevent the chain dislodging as it was likely to do if not set up correctly, or during the process of rigging the load, if there was too much slack in the chain. This new type is all new to me, looks like age is catching up

    Surprising how cheap lifting slings are. A 3m long 10 tonne rated sling with free postage only $85 on ebay.

    Thanks for all the advice, I learnt a bit about chains from this thread

    Looks like it it could end up being quite costly. It's only for a one off job at the moment but i'm sure i'll use it for other things again. I have a tree I need to pull out of the ground. My 1.5T come along can't quite get it, i'm sure if I tried harder I could get it to work out (water in the ground maybe)

    I might have to look into second hand chains. I only need between 2 and 3 metres probably.

    If the chain is only being used for pulling and never for lifting, remember certified lifting chains have a safety factor. I do not know if it is 2X or 4X.

    Also doubling a chain will get you more strength. Think of how skinny wire rope on pulley blocks lift huge loads.

    However stand well back no matter what you use. If anything snaps at high tonnage things will do a superman impression.
