what test loads for temp lift beams?
(OP)
I'm trying to find a reference for how much to load test a lift installation aid.
lift load 10 tonnes, suspended from a padeye that is welded to a temporary lift beam. The temporary lift beam is bolted (lindapters in tension) to existing deckbeams.
THere's a table somewhere that i've seen that recommends inplace test loads to appliy to rundway beams etc , but i can't remember the source.
i've been through BS 2573 part 1, but can't see a specific reference.
Aparently for a lift of 6 to 20t inclusive, i need to test load it to 1.5 x predicted load.But i can't find the back-up. I've got advise from test lift organisations, but have no back-up.
Suggested refernces?

have you been successful in making the lift? I am really concern with the method proposed to lift 10tonne weight! Supposed you already had a structural engineer checked the adequacy of lindaptors, and the supporting structure for such heavy lift.

Lets say you were handling between 10Te and 160Te; the proof load would be 1.04x (+9.6Te) of SWL. In addition, vertical loads for offshore cranes should have a minimum dynamic factor applied of 1.3x for the load range 1Te - 250Te (DNV B304).
(10Te x 1.04) + 9.6 = 20Te Proof Load. Add the dynamic factor of 1.3 = 26Te Proof Load. Hope this helps.
