RSJ, hoists and winches
#20
Boyle's Law concerning the behaviour of gases is directly related to garages, workshops and man- sheds, in as much that it matters not how big your available space is, you never have enough. The amount of stuff you accumulate expands in proportion to the volume available. P1.V1 = P2.V2

I built myself a new garage/man shed when we moved in 2007 and having done so I now find that I would have done it differently and of course, made it bigger. You would think that 64 square metres would be enough (26' x 26'). At the time it seemed so. I decided that I would need attic space for storage, and due the fact that I didn't want to have a central pillar I asked a structural engineer friend to do the calcs for an RSJ that would span 8 metres and then support the weight of additional masonry for the roof. It's a biggie! Its dimensions are 33cm x 16cm and it weighs over 400kg. It more than does the job.

Just thought I'd mention it for any of you wanting to tick a box in your "I Spy" book for girder spotters.
