A vessel for transporting a material that is solid or semi-solid at ambient temperature, includes a body having an interior surface comprising textured metal, and a superoleophobic coating on the interior surface for inhibiting the material from adhering to the interior surface, the superoleophobic coating including a nanotextured coating disposed on the textured metal and functionalized with a fluorinated compound. The superoleophobic coating facilitates flow of the material along the interior surface.

A dewatering unit in the form of a railcar having bogies thereon to move the unit on rail tracks. The dewatering unit has first and second ends, first and second sides, and a bottom that bound and define an interior chamber. A conveyor is provided in the interior chamber and screens are located in the bottom and first and second sides. A grizzly is located below an opening in the unit's top and above the conveyor. Stabilizing assemblies are deployed to contact the ground and lift some weight off of the bogies prior to loading. A solid material/liquid mixture is dropped through the opening and onto the grizzly which partially fractures the solid material. Further fracturing is undertaken by conveyor drag bars and crushers located adjacent the conveyor. Liquid drains from the unit through the screens. The dewatered solid material is lifted out of the unit by the conveyor.

A liquefied gas unloading and deep evacuation system may more quickly, more efficiently and more completely unload liquefied gases from transport tanks, such as rail cars, into stationary storage tanks or into truck tanks. The system may utilize a two stage compressor, an electric motor, a variable frequency drive, a four way valve, a three way valve, a two way valve, a programmable logic controller based control system and pressure and temperature transmitters. The valving enables deep evacuation of the transport or supply tank to more completely empty the transport tank. The programmable logic controller and variable speed drive may be used to variably control the speed of the two stage compressor so that the system may be running as fast as possible during changes in ambient temperature and/or different stages of offloading the liquefied gases without exceeding the compressor's horsepower limit.

A railcar for transporting one or more steel coils. In various embodiments, the railcar includes a front truck assembly, a rear truck assembly, a center sill assembly including a center sill operably supported by the front and rear truck assemblies, and first and second side walls supported by and substantially coupled to the center sill assembly such that the first and second side walls are spaced-apart from and substantially parallel to the longitudinal axis of the center sill.

A fixture system for rail transport of wind turbine blades upon a consist of flatcars using a root-support fixture, a blade-support fixture, and first and second guide post that intermittently engage the tip-end portion of the wind turbine blade to limit lateral movement thereof, such that movement of the consist around a curved railway section urges the wind turbine blade against the first or second guide posts, which urges the wind turbine blade to urge the blade-support fixture to move laterally, thereby laterally reorienting the blade upon the consist.

A self-driving steel coil transport vehicle capable of active steering includes a load-bearing device, bogies mounted below the load-bearing device, and wheels mounted under the bogies. Two bogies are provided and arranged in a front-rear manner along the running direction of the transport vehicle. Four wheels are mounted under each bogie, and the load-bearing device is articulated with the two bogies, respectively. The transport vehicle is drivable in both a straight line and curves.

The present disclosure discloses a road-rail dual-purpose vehicle, comprising a vehicle frame (1), and a lifting airbag mounting seat (1c) is provided between two longitudinal beams (1a) of the vehicle frame (1); a load-bearing airbag insertion hole is formed in a lower cover plate (1a1) of the longitudinal beam (1a); a load-bearing airbag mounting seat (1d) is installed in the load-bearing airbag insertion hole, and a bearing bolster (1e) is installed on an outer side of the longitudinal beam (1a). The road-rail dual-purpose vehicle is suitable for transportation.
