[0003]

However, in this prior invention of the applicant, the structure is such that the gas spring or the outer cylinder end of the hydraulic cylinder is connected to the beam member above the fixed frame only by the hinge. The side wall member could only be opened at an angle slightly exceeding 90 °, and the opening / closing operation thereof was not stable. Furthermore, this type of freight vehicle is roughly classified into wing cars, box cars, hood cars, etc. (excluding refrigeration cars, water tank cars, etc.). The wing car can be opened / closed by using the double-sided / single-opening or the upper / lower shutter type at the rear of the cargo box, and the L-shaped door is opened / closed by the oil cylinder with the both sides of the cargo box as the fulcrum. A box car means that the rear part of the cargo box can be opened / closed by double / single opening or upper / lower shutter type, etc.
It has a single-opening or shutter-type opening and closing function, and a hood car is made of a structural material such as pipes or angles at the rear of the loading platform to prevent wind and rain, and the surrounding and upper parts are protected by wind and rain with a sheet etc. It means something to do.

However, the wing car is expensive and not easy to remove, and since the side door structure is L-shaped, the turning radius of the outermost end is large, so that luggage can be loaded, especially from the top (when loaded by a crane or the like.
