A system for moving loads including a cargo compartment floor into which there is integrated at least one roller conveyor permitting displacement of a load in a direction parallel to a surface of said cargo compartment floor. The system also comprises a transport vehicle comprising a drive system and a platform movable between a first operating position and a second operating position. In its first operating position, the platform is arranged such that the transport vehicle is positionable under a load which is supported on the roller conveyor integrated into the cargo compartment floor. In its second operating position, the platform is arranged such that the load is entrained when a movement of the transport vehicle occurs in a direction parallel to the surface of the cargo compartment floor, and is displaced on the roller conveyor integrated into said cargo compartment floor.
