(Or pinwheeling) It refers to a method for loading trailers where you alter the direction of every other pallet. Basically you use pinwheeling to load more pallets on a trailer when the depth of the pallet is longer than half the trailer width, but the depth plus the width is less than the trailer width. You can also use it as a productivity/space utilization compromise or to reduce load shifting when loading pallets where the depth of the pallet is less than half the trailer width.
