ABSTRACT:
A hopper trailer includes a mobile support frame and at least one gravity-flow hopper having an open-top upper box portion and a lower tapered portion. The support frame includes a pair of longitudinal channels laterally spaced from one another and a pair of front and rear channels extending transversely between and rigidly connected to the longitudinal channels at the opposite front and rear ends thereof. The longitudinal channels have respective planar structural portions directly engaged with opposites sides of the lower tapered portion of the hopper. The planar structural portions of the channels are disposed in respective planes which converge downwardly toward one another so as to thereby support the hopper in a cradled relationship therebetween. The support frame also includes a gooseneck towing tongue connected to the front end of the longitudinal channels of the support frame and a ground-supported wheel unit connected to and underlying and supporting the laterally-spaced longitudinal channels.
