We had to wire wheel the underside of these 10 ton rolls, on a positioner so we could spin them but lying on your back with the roll 12" above with a flipping 9" trying to kill you!
Any way i had a day off came back next day expecting him to still be doing it (the rust was thick!!!)
Nope, he got a single bottle trolley, two broomsticks, two handles on the 9", and cable tied the whole lot together. Put the trolley under, push downwards, leverage makes the job easy!
