I have a 2013 xtrail st with a standard toward. We just got a camper trailer h
Woo hoo. The wight of the trailer is 674kg and allowed up to 1500kg when fully loaded. Thus I need 1500kg d shackles. The 1000kg ones fit well
But the 1500kg 11mm shackles don't fit the stupid tow bar. I know lots of you tow more than 1000kg.
So what does everyone else use for this. I have searched and can't find much

Re: D shackles again Hey Howie
hope this helps
here is all you need to know for what size shackle you can use i ill try to explain it a bit below
Firstly it depends on what size safety chain you are using im guessing 8 or 13 mm ( if it is above 13mm then it is a different chart for your bigger trucks and trailers ) but for my explanation ill go with it as 13mm chain .
firstly with towing you dont not go of the WLL ( working load limit ) you go of the BLL (Breaking Load Limit) if you have a grade S shackle ( alloy ) WLL of 1 Tonne it has a safety factor of 6 so it will not break until 6 tonne if it is a grade M shackle (mild steel ) it has a safety factor of 5 so will = 5 tonne
back to the info sheet
assuming you are using 13mm chain and your 1 tonne alloy shackle
1 tonne shackles breaking load limit is 58.9KN = 5.89 tonne
13mm chain breaking load limit is 51.6KN = 5.16 tonne
so as long as the shackle is equal to or greater than the strength of the chain its good to use.
so short answer yes your 1 tonne shackle is more the capable and legally able to carry a fully loaded trailer rated at 1500kg.
all info above is to Aus Standards.
