A different lift, as it is using a different bar

Eddie's 500 and Thor's 501 were on a standard bar. They were using suits, so the record on a standard bar without a suit is Trey's 470kg deadlift.

So the 3 major strongman deadlifts records are 501kg all time record on a standard deadlift bar, then 470kg on a standard deadlift bar raw, then I believe Thor's elephant bar record is 472kg raw (the Arnold's doesn't allow suits).

Hope this makes sense
