I never thought of using them for pallets. I use them for piling up logs or tree length wood, loading logs onto a trailer, carrying lumber. My pigpen is made out of 2x4 lumber and is 8 feet square, about 3 1/2 feet tall and topped with 2x4s and plywood. This spring I was able to pick it up and move it about 400 feet from one end of the field to the other. Without the forks I would have had to drag it, and it probably wouldn't have survived.
