摘要： A gondola car has a door and an associated door frame the end. The door hangs hingedly from the header of the frame. The header runs across the top of the door opening and is connected to the top chords at either side. The door posts are positioned inside the side sheets and tie into the header at each upper corner. The side sheets lap onto the door posts to allow longitudinal adjustment of the side assemblies and the door frame relative to each other, at assembly. The side posts are connected to the header with a tie plate that is bolted to both members. The car may also have a tarp dome at each end. The tarp dome has non-welded connections that have play to permit the tarp dome to accommodate movement of the top chords.

摘要： According to some embodiments, a railcar comprises an underframe and at least two hoppers coupled to the underframe. Each hopper is configured to transport a lading and comprises a transverse slope sheet and a discharge gate. The transverse slope sheet is coupled to a first side of the hopper and extends at an angle downward towards the center of the hopper forming a transverse discharge opening. The discharge gate is coupled to a second side of the hopper. The discharge gate is operable to move between a closed position where the discharge gate extends downward towards the transverse slope sheet restricting discharge of lading arid an open position where the discharge gate facilitates lading discharge. The orientation of the discharge gate is non-horizontal.

摘要： A bottom discharge open topped hopper car has a center sill with a bottom flange having laterally protruding edges. A shed plate assembly is provided to discourage accumulation of product on the exposed upwardly facing shelf otherwise presented by the bottom flange protrusions. The shed plate assembly may be mounted to the center sill in a manner that avoids impairment of the stress performance of the flanges of the center sill, whether by mechanical fastenings to other objects, or welding to objects that are not the center sill. The shed plate assembly may have walls having upper margins that are higher than the upper extremity of the hopper discharge opening such that the shelf of the center sill bottom flange is in the lee of, or sheltered by, the shed plate. The lading may thereby move under the influence of gravity past the shed plate to its desired unloading receptacle.

摘要： The present application provides a bottom door device and a hopper car, the bottom door device includes a first bottom door and a second bottom door, the first bottom door includes a first door end plate and a first bottom door plate which are fixedly connected, the second bottom door includes a second door end plate and a second bottom door plate which are fixedly connected, and a labyrinth seal is formed between the first bottom door plate and the second bottom door plate. By using a labyrinth seal to replace the overlapping sealing in the prior art, the bottom door device and the hopper car provided by the present application can still meet the sealing requirement on the premise that the two bottom door plates can be closed without complying with any specific order, thereby optimizing the structure of the bottom door device in the prior art.

摘要： A railroad hopper car discharge outflow is controlled by closure members, at least one of which is movable. The closure members (or doors) are hingeless, being mounted on four bar linkages, such that the distal edge of the doors sweeps predominantly horizontally while the proximal edge of the door moves predominantly upwardly. The doors move through noncircular arcs, such that the size of the vertically projected door opening is abnormally large compared to the clearance heights of the door during opening and closing. The doors are driven by a transverse drive linkage that is driven by a transversely mounted actuator. The actuator may be mounted in an accommodation in the lee of slope sheets between adjacent hoppers in a mid-span portion of the car. Drive from the actuator is carried to a pair of symmetrically mounted doors through drive train linkages.

摘要： A railway hopper car has longitudinally spaced hoppers on both sides of a center sill. The hoppers have door assemblies which may be opened and closed by a door operating mechanism. The door operating mechanism includes a pneumatic cylinder which rotates a lever to move an operating rod longitudinally within the center sill. Door operating levers are rotatably supported on the railway car and pivotally connected to the operating rod to be rotated when it moves. The door operating levers are pivotally connected with struts connected with the door on the hoppers. The mechanism is configured so that all forces are substantially coplanar in a vertical plane passing through the centerline of the center sill to reduce lateral twisting forces in the mechanism. Adjustment of the length of the strut is provided for positioning of the door operating levers during assembly.

摘要： A high volume covered railway hopper car is disclosed which has vertical end walls so as to fully utilize the space over the trucks of the car for lading volume. An automatic pneumatic unloading system is provided so as to unload a pulverant lading from the end compartments or hoppers, as well as the center, of the car, thus eliminating the necessity of sloped end sheets. A pneumatic loading system is provided which permits loading from below and thus permits the elimination of hatches, walkways, and the like on the roof of the car so as to permit the roof to extend substantially the full extent of AAR height clearances thereby to further maximize the lading volume of the car.

摘要： A device for unloading a container used for bulk materials is such that a container floor is made up at least in part of flaps which can be tilted or swung out away from the interior. To this end at least two flaps are connected via a ridging beam or axle which runs through the interior of the container above a rotatable shaft. The rotational movement of the shaft is transmitted to the flaps to actuate same. The shaft features on opposite sides and transverse to its longitudinal axis first and second flange pairs, the former accommodating an elbow lever with the help of a push-fit bolt, and the latter a lever with the help of a bolt. The elbow lever and the lever are hinged to the flaps respectively. Further, connected to the flaps is a lock which joins up via bolts with the elbow lever or the lever, and in the closed position engages on a latching device.

摘要： An apparatus for actuating and locking each pair of hopper doors of a railroad hopper car of the type having a plurality of hopper doors arranged in opposed pairs and extending transversely of the hopper car center sill. Each door actuating and locking apparatus for each opposed pair of hopper doors comprises a shaft assembly extending transversely of the hopper car between its respective opposed pair of hopper doors and through the hopper car center sill and the inner and outer hopper sheets for those hopper doors. That portion of the shaft assembly located within the center sill has an L-shaped lever structure non-rotatively mounted thereon. The lever structure is connected by links to the hopper doors of its respective pair. Either end of the shaft assembly can be engaged externally of the hopper car by an approriate tool to rotate the shaft assembly and its lever structure between a door open position and an over-center, door-closed and locked position.
