We're doing a self build which is actually a conversion of a current industrial building. It has a large flat roof which is supported by 3 x 11m long i-beams, approx 450mm x 300mm section, and they need to be raised by a few feet up to a height of around 7.5m. My question is, for a beam this size (i'm still trying to confirm the weight, but i know it's substantial, is a crane out only option, or is there some other solution using a Genie type lift?
