Abstract:
A chassisless fiberglass tank trailer. The tank trailer includes a tank shell formed of a fiberglass reinforced isotholic resin, with fiberglass filaments bias-wound at an angle of approximately 45. degree. The tank shell has a forward head and a rear head for forming a fluid carrying container. A forward cradle is attached to the tank shell with mounting portions used for mounting a fifth wheel member, and a rear cradle is attached to the tank shell and having mounting portions used for mounting a rear wheel carriage. The cradles further include a plurality of holes extending therethrough and a plurality of protrusions extending therefrom. The holes and protrusions interact with the resin and fiberglass winding to rigidly hold the cradles to the tank shell. A plurality of circumferential reinforcing ribs are located between each of the mounting portions and at other desired locations longitudinally on the tank shell. The ribs are also molded in with fiberglass reinforced resin.
