I made this ramp to load a piano into the truck. It is made from 2×10 SYP eight feet long with two aluminum brackets rated for 700 pounds each. I added two five foot sections underneath to add more rigidity, plus the two side rails. It worked fine with a 500 pound piano plus four people pushing and pulling.The ramp also worked well to span steps going into the house, so we didn't have to lift the piano off the ground.
