Abstract: 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.

Abstract: A movable side wall and opening/closing mechanism for railroad boxcars, comprising a side wall assembly (1), an end-portion opening/closing mechanism (2), a hinged rod assembly (3), a lateral door central clamping device (4), a upper transmission shaft assembly (5), a lower transmission shaft assembly (6), a upper track assembly (7) and a lower track assembly (8); 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 (3) and the central clamping device (4) are provided to keep the movable side wall reliably closed in order to ensure security and self-locking during transportation.

Abstract: A straddle-type multimodal transportation interworking system at least comprises: a rail system (30), a cargo vehicle (140), a transfer apparatus (32) and a processor. The cargo vehicle (140) can be movably provided on a rail beam (170) of the rail system. The transfer apparatus (32) is used for transferring a goods loading device (33) from a transportation tool to the cargo vehicle (140) and loading the same onto the cargo vehicle or unloading the goods loading device (33) from the cargo vehicle (140) and conveying the same onto the transportation tool. The processor is connected to the cargo vehicle and the transfer apparatus.
