Description

{TRANSFER TRUCK OF ASSEMBLY TYPE}

The present invention relates to a goods transporting truck.

Generally, in various industrial sites, there are many cases where various parts or products being produced or finished articles produced are to be moved to a specific place in a workplace. In such a case, it is a truck for transportation.

Such a bogie has been developed in various forms depending on the type of the article to be transported and its intended use. In the most general form, a plurality of casters are installed on the bottom of the bogie to facilitate movement and direction change. It is equipped with a handle to allow movement by manpower, and it is mainly installed in the dock to be used jointly by several companies.

However, the above-described conventional work carriage has the drawback that the area of the plane on which the articles are stacked is limited to a certain size, which is not suitable for transporting a bulky article.

Accordingly, when the article is carried by a bogie, the number of the articles to be loaded on the bogie is limited, so that the number of the bogie is limited when it is necessary to carry many articles. Therefore, There are problems such as delay in delivery time of goods, delays in delivery of intermediate goods, delays in repetition, and the like, resulting in a decrease in productivity of direct marketing (DM).

Conventionally, a bogie capable of adjusting the height of the bogie to vertically stack the bogie has been disclosed. However, the amount of the bogie to be stacked on the bogie is limited to the upper and lower bogie planes.

Particularly, all of the bogies described above have no means for holding the loaded article when the bogie is moved from the raised state to the bogie. When the bogie is inclined or uneven on the moving route of the bogie, There has been a problem that the packed product falls or breaks due to impact.
