Crane loads - Slab On Grade
Crane loads - Slab On Grade
(OP)
I have a 5" thick 3.5ksi concrete slab. The contractor wishes to load the slab with a crane used for lifting and placing panels. The maximum outrigger applied load is 115k!! The crane sub insists this is ok if using 6ft x 6ft steel plates to spread out the load. I figure this reduces the stress to about 22 psi if I assume a rigid plate. At first glance this looks as though it will work, am I missing anything, should I be concerned about sub-grade reaction? Any tips or insite would help.
Thanks,
