stone/sculpture lifting equipment

["Clive Murray-White" <clivemw@xxxxxxxxxxxxxxx>]

Dear Simon,

Thanks for your detailed description, I must admit that this solution is
looking like the most flexible but your scaffolding people must be a bit
different to mine.

Everyone down here is too frightened to tell you how much weight their
scaffolding can carry if you are using it as a lifting device, I can't blame
them because, I wouldn't want to be sued either.

The hardest information to get is some general indication of the loadbearing
properties of various sections at various lengths, most crucially the bits
that you are going to use as the top bars when reinforced with diagonal
braces.

Basically, I'd been told that scaffolding was too light/week and that I
should consider what they call "shoring" (used in creating concrete form
work).

As I am not an engineer, the information regarding stress and loading
usually described in frightening looking bits of algebra in the steel Co's
product information sheets are almost unintelligible to me!

Regards Clive
