A movable side wall and opening/closing mechanism for railroad boxcars, comprising a side wall assembly (), an end-portion opening/closing mechanism (), a hinged rod assembly (), a lateral door central clamping device (), a upper transmission shaft assembly (), a lower transmission shaft assembly (), a upper track assembly () and a lower track assembly (); upon loading/unloading cargo, the movable side wall can be opened further, so as to allow multiple forklifts of any tonnage on the ground to load/unload cargo to/from any positions of a carriage; the hinged rod assembly () and the central clamping device () are provided to keep the movable side wall reliably closed in order to ensure security and self-locking during transportation.

Movable side wall and opening/closing mechanism for railroad boxcars

The present invention discloses a sidewall structure of a hopper car, including: an integrally formed upper side beam (), an integral sidewall panel (), an integrally formed lower side beam () and a lower sidewall (), wherein the upper side beam () is riveted with the integral sidewall panel () at the lower side; the sidewall panel () is riveted with the integrally formed lower side beam () at the lower side; the sidewall panel is of a panel-column structure in which the wall panel is integrated with a side column, and the side column is arranged at the inner side of the car body; the lower side beam () is riveted with the lower sidewall () at the lower side. According to the sidewall structure of the hopper car provided by the present invention, because of the sidewall panel with the integrally built-in side columns, the strength reduction resulting from rivet holes is avoided, the increased weight and cost resulting from rivets are avoided as well, and since the side columns are built-in, the spaces between the side columns are utilized to increase the volume of the car body.
