Vehicle Loads
Vehicle Loads
(OP)
I need information for vehicle loads that I can't seem to get a straight answer for. I am involved in the design of concrete pad at a plant site that will be subject to infrequent vehicle loads. The vehicles that will be driving on this pad will be pickup trucks, large forklifts and small cranes for access to a pipe rack.
I'm assuming that the crane will be the heaviest piece of equipment, but I'm finding wildly varying weights for cranes. I do not have any specific information as to make or model of the cranes that might be used. Does anyone have a rule of thumb for vehicle loads that would fit this scenario?

RE: Vehicle Loads
If the cranes are unloaded when they pass over the slab, I'd check for an AASHTO H-20 load. If they're loaded, you'll have to logically limit the type of crane and capacity that can travel over the slab.

For areas that are used (abused?) for heavy duty bulk material handling, 12 inch slabs with two mats of rebar (placed on the quality subgrade described above) seem to be able to take anything that plant operations can dish out.
