Abstract: A basket frame for a traveling water screen includes a pair of hollow parallel lip beams connected together by end plates which are secured to the lip beams by plugs fixed to the ends of the hollow lip beams. The hollow cores of the lip beams are sealed against ingress of water so that the basket frame is buoyant in water. The lip beams are formed of pultruded fiberglass with cross sectional shapes which are provided with complementary curved surfaces so that the adjacent lip beams on adjacent baskets provide a close fitting seal on the vertical run of the basket train and also on the curved section at the bottom of the basket train where the baskets make the turn around the traction wheel.
