Hi Sideways, agreed on being careful on tail lifts.Most Luton tail lifts are only rated to a half ton, or even just 250kg and there is plenty of machinery that exceeds that.
It was sometime mid 2000's Harrogate show and Freud were using pallet crates (basically a pallet with 3ft sides around it) to remove all their stock after the show.
The crate was fully stacked up with saw blades / router bits etc - basically it was almost a solid lump of metal weighing goodness knows how much.
I was walking past them when their tail lift broke off on one side and dropped - they were very lucky and no injuries - the whole crate fell off and tipped onto the ground with hundreds of blades and bits going everywhere in the darkness.
