Title
(EN) RAILROAD HOPPER CAR STRUCTURE AND GATE THEREFOR
(FR) STRUCTURE DE WAGON-TRÉMIE DE CHEMIN DE FER ET PORTE ASSOCIÉE
Abstract
(EN)
A railroad hopper car has a hopper carried between two trucks. The hopper has convergent end and side slope sheets that feed a flat bottom discharge. It has a rectangular frame at least half as wide as the car, and at least half as great as the truck center distance. The car capacity is over 5000 cu. ft. The bottom discharge is lower than the center sill. There are ring frames having a bottom cross-member that passes clear under the center sill. The car has flat bottom discharge gates having multiple arrays of louvers. The side sheets extend downwardly beyond the side sills, so that the side slope sheets terminate at a transition below the side sills. The louvers have curved edges. The louvers move together. The gate may include two opposed sliding doors separated by a beam that runs under the center sill.
(FR)
L'invention concerne un wagon-trémie de chemin de fer ayant une trémie portée entre deux bogies. La trémie comprend une extrémité convergente et des tôles inclinées latérales qui alimentent une évacuation inférieure plate. Elle présente un châssis rectangulaire au moins aussi large que la moitié de la largeur du wagon, et au moins aussi grand que la moitié de la distance centrale du bogie. La capacité de wagon est supérieure à 5000 pieds cubiques. La décharge inférieure est inférieure à la longrine centrale. Il existe des châssis annulaires ayant un élément transversal inférieur qui passe nettement sous la longrine centrale. Le wagon comprend des portes de décharge inférieures plates ayant de multiples réseaux de persiennes. Les panneaux de parois latérale s'étendent vers le bas au-delà des brancards, de telle sorte que les tôles inclinées latérales se terminent au niveau d'une transition au-dessous des brancards. Les persiennes présentent des bords incurvés. Les persiennes se déplacent ensemble. La porte peut comprendre deux portes coulissantes opposées séparées par un faisceau qui s'étend sous la longrine centrale.
