The present disclosure provides a trailer and a vehicle. The trailer comprises: a structural beam; and at least one container protector installed on the structural beam; wherein the container protector comprises a drive member and a protection member, the drive member being adapted to drive the protection member to rise and lower, and the protection member being capable of providing a limiting function for a container on the trailer when raised. The present disclosure may automatically raise the protection member after installing the container on the trailer so that the protection member locks the container; before the container is to be unloaded, the protection member is automatically retracted to release the limiting function for the container. In this way, it is no longer necessary to specially manually tighten or loosen a shackle of a container, realizing the intelligent control of cargo loading and unloading.

A system to transport and unload bulk materials includes at least one rail car and a moving wall system. The moving wall system has a first end, a second end, and a trough. The trough is configured to contain a payload of the at least one rail car. The trough includes sidewalls that contact the payload when loaded and move with the payload to move the payload towards the second end. The trough may be formed of at least one conveyor belt that forms a hopper of the at least one rail car. The trough may span a plurality of rail cars. The system may include a take-up system connecting the sidewalls. Each of the rail cars may include a frame and a plurality of pulleys connected to the frame may support the trough.

A single drive dual hopper conveyor system is presented having a center conveyor system and a pair of side conveyor systems that are connected to one another. A single motor is connected to the center conveyor system and drives movement of a belt within the center conveyor system. The connection of the center conveyor system to the side conveyor system causes the belts of the side conveyor systems to be simultaneously driven as the belt of the center conveyor system is driven. This arrangement eliminates the need for multiple motors. A guide at the center of the belts is configured to guide the belts through the center of the housings and prevent the buildup of grain within a cut-out section of the flights of the belt that is needed to allow access to the links of the belts to facilitate driving of the belts.

A modular cargo storage system (CSS) is described for use on a base platform of a modular autonomous bot apparatus that transports an item being shipped. The modular CSS includes a set of folding structural walls, an interlocking alignment interface on at least one of the walls, and a modular component power and data transport bus. The walls at least partially enclose a payload area above the base platform. The interlocking alignment interface has a set of latches and a locking handle coupled to the set of latches that actuates the latches to interlock with the base platform. The power and data transport bus have top and bottom side modular component electronics interfaces where each interface has a power conduit outlet and a command and data communication interface.

A system for loading/unloading solid materials from an open top rail car is described. The system may comprise suitable safety features, structural reinforcement and loading features to permit operation of the system by a single operator in a safe manner. In some examples, the system comprises a crawler excavator reversibly coupled to a sled attachment to permit movement of the crawler excavator along a top surface of an open top rail car.
