OSHA and (or) building code regs on lifting 2

[WARose]

I recently had a project where I checked out something to be lifted and approved it. But as far as the actual lifting goes, I referred the contractor to OSHA/Building Code regs for providing lateral stability. I assume my responsibility ends there (baring any follow up questions from him which I haven’t gotten)……but does OSHA, etc. specify a minimum capcity for (say) a guy wire support from the ground? I remember reading that for a man lift the load was something like 5 kips. I was messing around with a probable [guy] layout and I didn’t get forces much higher than a couple of kips (forgetting wind load for a second). (So I just hope these guys don’t try to stabilize it with a couple of people on the ground: they’ll go for a ride.)

and look for standard 1926 “Safety and Health Regulations for Construction. Then just start digging, since I don’t really know what your involvement is. Then there are also some lifting regs. for below the hook conditions and for riggers.

Most rigging equipment must be "certified" by approved source. I have seen a number of lifts postponed because the crane operator refused to use anything that was not certified. Also,I have often seen a FS of about 5:1 used.

I think the 5:1 safety factor is for the crane vertical load [I've heard it before myself]......here I'm thinking more about the cables that go to the ground (that provide stability).

I've looked around in there and can't really find anything that directly addresses my situation.

I would think what is probably called for here is a temporary wind load.....and I know where I can find that…..just wasn’t sure if OSHA specified something heavier than that (maybe a percentage of the vertical load).

If you lose a guide line????? Staying with 5:1 isn't expensive and thee loads are usually quite low.

Crane hoists don't rely on guy wires, so you're raising up something that will be guyed off?
You mention wind load but not ice? Communication masts and towers are covered by TIA/EIA-222.
You have to include wind harmonic vibrations on both mast and guys, including terrain effects.
You're better off sub-bing that out to a specialist to avoid 'area of practice' liabilities.
