A loading device 1 for loading and unloading of a cargo hold having at least one conveying system for positioning cargo units in the area of a floor space of the cargo hold, and with at least one guiding element guiding the conveying, and a movement aid in the area of the floor space 11 of the cargo hold 5 enabling rotation and movement of the cargo unit. Sensors detect the presence of a cargo unit in the area of the conveying system without contact the position of a cargo unit on the floor space is determined in at least two spatial dimensions without contact. The sensors make it possible to control rotating movements of the cargo units in the area of the respective conveying systems by a controller.

A vehicle cargo space includes a rear lift gate moveable between opened and closed positions to allow movement of palletized containers into and out of the cargo space. The cargo space has a substantially horizontal floor with first and second sets of laterally spaced, parallel, longitudinal tracks. The tracks extend from the front to the lift gate at the rear of the cargo space. At least one set of tracks is positioned transverse to the longitudinal tracks. The tracks slidably support cargo container pallets. A system of actuators, guides and locks enable programmed movement of the pallets along the tracks into and out of the cargo space as well as within the cargo space.
