A loading system for loading and unloading cargo compartments of trucks includes chain conveyors positioned parallel or substantially parallel to one another and such that standard pallets can be moved back and forth on the chain conveyors in a conveying direction. An autonomous conveyor vehicle is provided as a component of the loading system, and the chain conveyors are positioned at a height above a floor so that the conveyor vehicle with vertically movable pallet fork assemblies can be positioned below the chain conveyors.

An inversion mechanism inverts a first container held by a holding mechanism with a first opening directed upward, and directs the first opening downward. A movement mechanism moves the holding mechanism so that the first opening directed downward faces a second opening from above. The opening and closing drive mechanism brings an opening and closing member into the closed state while the holding mechanism is inverted by the inversion mechanism and while the holding mechanism is moved by the movement mechanism, and brings the opening and closing member into the open state in response to the first opening facing the second opening.
