A roll bar is not a lifting point. They are very very much not the same.

 

is the difference tension vs. compression? I'd have thought the roll bar would be pretty firmly attached to the chassis?

AFAIK the difference comes down to materials, fabrication, weld content, type..... We get nailed with this sort of stuff at work (Lifting Register), where you will have design drawings, material specs, welding details, inspection details etc etc.......

But still impressive to see...... Poor bugger......

Yes Russ more or less. A roll bar/cage is designed for compression loading essentially. For example if you roll a car with a bolt-in cage the load is sent to the floor pan via the feet on the cage. When you lift something via the cage you are only loading the bolts holding the cage in.
