ABSTRACT:
A railroad hopper car discharge gate is assembled from unitary stacked frames that provide unimpeded flow of lading during discharge. A low-wear glide system minimizes friction between the gate panels and other components of the apparatus, and an improved sealing system protects lading from contaminants such as rain, dust and insect infestation and provides enhanced vacuum sealing for greater efficiency during vacuum discharge.
