A pallet that will hold 6 supers per row. The sides of the pallet have plywood fenders so the supers don't slide off the side when I am moving them with the lift. I use a sheet of plastic on top of the pallet to set the supers on.
For a hobbiest(when I had less than 100 hives) I used drip boards. Plywood the size of the super, A cleat on each end on the bottom so the dolley would get under it, a piece of coil stock(painted white aluminum) on the top, and a 3/4" x 3/4" rim on top of the coil stock to keep the bottom of the frames from sitting on the bottom of the drip board.
