ABSTRACT:
A railroad hopper car comprising an elongated car body having a plurality of laterally pivoted bottom discharge doors; a door opening and closing elongated beam assembly positioned longitudinal of and along the bottom portion of the car; a plurality of spaced apart door operating levers mounted on a pivot lateral to the car body along and to the bottom of the car; the door operating lever pivot including a lateral shaft to which the operating lever is fixedly joined; a pair of laterally spaced apart supports on the car body beneath the elongated beam assembly with each support carrying a bearing mount for the door operating lever pivot; each bearing mount being fixedly joined to the support at a position determined by the actual position of the beam sections when installed rather than at a predetermined location on the support thereby making it unnecessary to include elements to adjust the length of each beam section.
