On the catalogue picture on Rebrickable (https://cdn.rebrickable.com/media/thumbs/sets/2700-1/784.jpg/1000x800p.jpg) the two yellow 2x4 Duplo bricks listed in Bricklink inventory are used as goods in the tipper and hanging on the crane. And there are two additional yellow 2x2 Duplo bricks in the base of the crane.
