    Cantilever Crane Rail

    That's a good point. I'll have to look into that. Thanks for the input!

    Cantilever Crane Rail

    They wouldn't object, but it's basically impossible. These rails stick out of a pressure vessel. There's a door that closes over it, with two pockets to capture the rails. The only possible solution would be temporary stands that they put underneath each rail. This isn't impossible, but would be...

    The deflection would be minimal. I'm estimating less than 1/16". Not to get too far into the weeds, but the reason they want to leave this as a cantilever is because they are having a problem with the existing set up. The left hand side with the slab sits on a hydraulic lift. It comes up to...

My understanding from reading OSHA is that each anchor point needs to be designed for 2 times the MAF, which for a...
