Bruce Bleikamp, director of product management at MHS, estimates that only about 2% of the SKUs in a typical DC are non-conveyable. But as Jensen points out, that number can run as high as 15% or 20%. And then, he adds, there are appliance warehouses where an even higher percentage of SKUs require special handling with a clamp truck or other device. The same would be true at a furniture warehouse.
As you already suspect, that means there are no standard solutions to moving and tracking non-conveyables. And while there is no cookie cutter solution here, this is not an impossible task.
