An arrangement for loading, transporting, and unloading goods into and out of a truck-carried container (1) that includes a vertically moveable intermediate floor. The invention is characterised in that the intermediate floor is divided into two or more sections (1-6) in the longitudinal direction of the container. Each intermediate floor section (2-6) can be moved vertically along guide rails (7-10) fitted to the inside of the long container sides (11, 12), from a lower limit position (14) to an upper limit position (13). The arrangement includes no floor-section drive means. A locking device (16, 17) is provided at the upper limit position.
