Abstract
A side dump trailer that empties to either side includes a generally rectangular chassis with front and rear axles, each having a pair of wheels, with the front axle secured to the chassis via a swivel connection to allow steering of the trailer with a tongue. The chassis has an elevated rectangular open top box trapezoidal in cross section with a closed bottom supported on the chassis and a larger open top. The box is fastened to the chassis by four pairs of cylindrical bushings, one of each pair fastened at each corner of the box and the other of each pair fastened to the chassis. The bushing pairs each receive a removable connector pin. Removing the connector pins from bushings on one side of the box allow the box to pivot and dump to the opposite side of the trailer.
