The retainer 24 includes a seal damming portion 24a that protrudes toward the opening portion 10.

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.

The present disclosure relates to an apparatus for automatically locking a container, which includes: a cylindrical housing: a top plate installed on the top of the housing; a bottom plate installed under the housing; an elevation unit installed to move up and down in the housing; a locker installed to rotate left and right to lock and unlock a container; a guide guiding up-down movement and rotation movement of the locker; a first elastic supporting member elastically supporting upward the elevation unit; and a second elastic supporting member elastically supporting upward the locker. Accordingly, the present disclosure provides an effect that a container is automatically locked or unlocked by its own weight when it is loaded or unloaded, so it is possible to safely transport heavy containers always in a locked state and it is possible to prevent malfunction or poor function of the locker.

A system for manufacturing a wheel includes a cope mold portion with internal cope mold walls and a drag mold portion with internal drag mold walls. The internal cope mold walls and internal drag mold walls define at least in part perimeter boundaries of a wheel cavity. The wheel cavity includes a cavity center portion configured to form a wheel center portion of a wheel after solidification of a molten alloy in the cavity center portion, a cavity plate portion configured to form a wheel plate portion of the wheel after solidification of a molten alloy in the cavity plate portion, and a cavity flange portion configured to form a wheel flange portion of the wheel after solidification of a molten alloy in the cavity flange portion. The system includes a chill component positioned within the wheel cavity adjacent the cavity flange portion. The chill component is configured to provide directional solidification from the cavity flange portion toward the cavity plate portion of molten alloy in the wheel cavity.

A system for distributing auxiliary power onboard of a train including a first car, a second car, and a third car equipped each with electric loads, including: a power distribution line extending across the cars; a first, a second and a third auxiliary power generators each configured to supply power to the electric loads on the first, second and third cars, respectively; a first and a second auxiliary power switching devices positioned along the power distribution line between the first and second auxiliary power generators and between the second and third power generators, respectively; a third and a fourth auxiliary power switching devices positioned along the power distribution line at the second car. When one of the auxiliary power generators is faulty, loads installed on the car affected by the faulty generator are supplied by one of the other auxiliary power generators via switching of the power switching devices.
