A system for moving loads, in particular within an aircraft, comprising: a cargo hold floor, at least one row of rollers including a plurality of rollers integrated into the floor one behind another, at least one guide rail in the floor extending substantially parallel to the row of rollers, and at least one transport vehicle removably received in and movable along the guide rail. At least one coupling arrangement selectively couples the vehicle with a load arranged on the row of rollers, the load being movable with the vehicle. At least one locking arrangement, in an active state, locking the load relative to the floor and, in a non-active state, allowing a relative movement between the load and the floor. The vehicle operates the locking arrangement according to at least one of the following: so that it assumes the active state; and, so that it assumes the non-active state.
