[0002] A boxcar, also known as a covered wagon and commonly called a tank car, is an enclosed train carriage generally used to transport goods. Although more complex in design and manufacture than a flatcar, the boxcar is one of the most versatile types of railway freight carriages. The boxcar has open doors on its side, the size and opening / closing method of which depend on the designed use. Some tank cars for transporting large-volume goods are also equipped with rear open doors and adjustable partition walls.

[0003] Based on the above, the inventor found the following problems: Since the daily operation volume of current railway freight boxcars is not fixed, sometimes more and sometimes less, it is difficult to hire a large number of standby workers for a long time. Sometimes when there is a concentrated shipment or arrival of bagged goods such as chemical fertilizers and grains, it is impossible to take measures to temporarily increase the hired manpower to solve the backlog situation of loading and unloading the cars. Therefore, multiple problems such as low operation efficiency of the boxcar, long loading and unloading time, and slow turnover of railway vehicles and freight positions occur.

[0004] Therefore, in view of this, research and improvement are carried out on the existing structure and deficiencies, and a mobile loading and unloading device for railway freight boxcars is provided, with the expectation of achieving a more practical value purpose. Content of the Utility Model
