Abstract: The hopper bottom trailer has a main frame supported by wheels, a hopper with hopper walls that extend downwardly to a discharge opening and a discharge door, and two side walls. An upper side frame member is attached to each side wall. A front upper frame member and a rear upper frame member are secured to the upper side frame members. A forward inclined floor panel is pivotally attached to the front upper frame member and a rear inclined floor panel is pivotally attached to the rear upper frame member. The forward and rear inclined floor panels are pivoted from an inclined position in which grain can slide down their surfaces to the hopper to a raised position which opens the inside of the trailer to receive elongated cargo.
