Abstract: A conveyor bed has opposed sides and transverse nose bars on the ends of the sides to form an open frame. The sides carry also rungs. Elongated wear strips lay on the rungs to form a deck for a conveyor to slide thereon. The ends of the sides are formed with open mortises. The nose bars extend between opposite lateral ends formed a T-headed tenons. The tenons releasably couple with the open mortises. Hence the nose bars are adapted to couple onto the ends of the sides be locked there by the felt weight of the conveyor rolling over the nose bars. The elongated wear strips have an upper edge forming a conveyor supporting surface and a lower edge formed with notches. The notches are sized for receiving the rungs. Thus the notched wear strips are adapted to be weighted down in place on the rungs by the weight of the conveyor sliding thereon. The notches are sized for closely fitting the rungs to better stabilize the wear strips from unwanted displacement.
