I am after some ideas of what people have/are using for the safety chains and attachments for a trailer rated for 4.5 ton.

GR80 13mm rated to 5.3t and use 13mm hammerlocks to secure...........any lifting gear place will have it.
Confidence.......the feeling you get before you fully understand the situation.
I was thinking of using hammer locks and then shackles to attach to the vehicle. I need to have 2 chains and I think they both need to be able to take the load each. The chain can't be welded and rated for the said load. When you size up a 4.5 ton shackle it would certainly never fit through the chain. I may be reading the regulations wrong.
The catch in the regulations/recommendations is the difference between "safe working load" and "breaking Strain" as I read it in relation to D shackles. I think the general rule for rated lifting shackles is the breaking strain is 6 times the SWL so 2 tonne SWL shackles should be heaps - but have another read - don't take my word for it.
I use 13mm hammer locks & 3.2tonne D shackles...that is as big as I can fit in chain.
Thanks people and thanks for the link creat pretty well explains what is required.
