A hatch cover assembly for a hopper railroad car includes a door configured to move from an open position to a closed position, a running track configured to support the door in the open position, a roller assembly attached to the door and configured to move along the running track, a locking clip configured to engage a leading edge of the door, and an actuator configured to move the door between the open position and the closed position.

A hopper railroad car hatch cover including an elongated movable flexible hatch including an elongated flexible panel and an elongated magnetic coaming sealer connected to the bottom of the elongated movable flexible panel, wherein the elongated magnetic coaming sealer is configured, such that when the elongated movable hatch of the hatch cover is in the closed position on a coaming of a hopper railroad car, the elongated magnetic coaming sealer engages and creates a seal with the coaming.

Disclosed is a railway hopper car comprising a car body (6), a top cover (1, 2), a bogie (24), a braking device (21), a coupler buffer device (22), and a bottom door (25, 28) and a bottom door opening and closing mechanism (23) mounted at a discharge port at the bottom of a chassis. The railway hopper car further comprises a longitudinal saddle (31) disposed in the center of the car body (6) in the length direction thereof and arranged along the longitudinal direction of the car body (6). By providing the longitudinal saddle (31), the sequential requirement to close the left bottom door (25) and the right bottom door (28) is eliminated, thereby simplifying the structure of the linkage bottom door opening and closing mechanism and reducing manufacture and maintenance costs thereof.

The invention relates to an openable structure for a substrate, such as a lorry, trailer, semitrailer, railway wagon, dumper truck or container, comprising a tarpaulin framework to which, for example, a tarpaulin made of weather-resistant material or a plurality of hingedly couplable wall elements can be connected, wherein the tarpaulin framework has a plurality of slides which are shiftable along at least one guide, wherein the guide comprises a longitudinal member element along which the slides are shiftable. An openable structure permitting smooth opening and closing of the structure is provided according to the invention in that the longitudinal member element is arranged adjustably at least in sections in a direction transversely with respect to the shifting direction of the slides.

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.

The invention relates to a tarpaulin structure for an understructure, such as a truck, trailer, semi-trailer, railway car, dump truck or container, comprising a folding-top frame (16) and a tarpaulin (12) made of weather-resistant material, the folding-top frame (16) includes a plurality of struts (34); at the end, each of the struts has a carriage (32) that is movable along a guide (20), at least one bracket (36) is selectively pivotally connected to a pair of opposite carriages (32; 32) of the strut or to the strut (34); said bracket (36) forming a tarpaulin folding aid along with a bracket (26; 36) of an adjacent strut (34), of a pair of opposite carriages (32; 32) or of a stationary part (24) of the folding-top frame (16). In order to create a light-weight tarpaulin structure that allows an understructure to be reliably covered, according to the invention, the adjacent brackets (26, 36) are coupled to each other by means of a kinematic connecting rod assembly (38) that folds when the folding-top frame (16) is collapsed.

Transportation methods, systems and covers for transporting hot ingots or sows are disclosed. The transportation system includes a base, at least one stack of ingots, and at least one cover positioned over the at least one stack of ingots. The transportation system may also include a securement assembly configured to secure the at least one stack of ingots and at least one cover to the base. A transportation method using the transportation system to deliver hot ingots to a processing facility is also disclosed.
