System for moving loads in an aircraft

A system for moving loads in an aircraft, comprising:

• a cargo hold floor,
• at least one roller track, which comprises a plurality of rollers arranged one behind the other in the cargo hold floor, wherein the rollers define a plane of movement for the load,
• at least one guide track, which is provided in the cargo hold floor and extends substantially parallel to the at least one roller track,
• at least one transfer vehicle, which is received detachably in the guide track and is configured to be moved along the guide track,
• at least one locking device, which is configured, in a locking position thereof, to block movements of a load relative to the at least one roller track in a direction parallel to the plane of movement and in a direction perpendicular to the plane of movement and, in a release position thereof, to allow relative movements,
• wherein the at least one locking device is configured in such a way that the at least one locking device can be actuated by a transfer vehicle in the guide track in order
• to shift the at least one locking device out of the release position into the locking position, or
• to shift the at least one locking device out of the locking position back into the release position.
