Abstract

The present invention relates to a box truck having a height-adjustable loading container and, more specifically, to a box truck having a height-adjustable loading container, in which the height of a loading container capable of loading a cargo can be adjusted according to the loading amount of a cargo and the situation of a loading/unloading site. A box truck having a height-adjustable loading container according to the present invention has a loading container of which the height can be freely adjusted within a regulation range, to maximally use a loading space and enable the truck to enter an underground parking lot where the height thereof is limited or a road where road access is impossible, and thus can not only improve the convenience of loading or unloading but also expand the operation area thereof.
