engine ~200kg, ~260kg with ancillaries - I use these for my engines, can safely manage 680kg - they're strong as an Ox and very stable when moving around
Fully agree about the crane, used that model when replacing the chassis on my 90 a few months ago and it served me perfectly.
Bought new for the job in hand and then sold on, made financial sense as delivery was free and I lost relatively little money between purchase & sale but it meant it was there all the time I needed it unlike if I had rented one.
Sold for £180 (inc load leveller) within minutes of being listed on the forum.
