with all due respect, I highly doubt that any supervisor or manager is going to bother calling the manufacturer to determine whether they can pick up a load or not, even tho what you say is correct. In the real workplace, they say 'pick it up. If the back end lifts, its too heavy.'

Altho I teach the 1"=100lbs method, it goes in one ear and out the other, but as I tell my students, 'I won't be there on Monday to babysit you'
