A vehicle comprising a loading space and a system for transportation of goods that is installed in the loading space of the vehicle, wherein the vehicle is preferably an aircraft, the system is for transportation of goods in a loading space in the aircraft, preferably for transportation of baggage in a loading space of a passenger aircraft, and wherein the system comprises at least one conveyor running substantially parallel with the floor of the loading space, intended to have goods placed on it and drivable to and fro in the loading space, whereby the conveyor comprises a first element comprising a goods-bearing belt and a wall disposed transversely to the driving directions of the conveyor, the goods-bearing belt being fastened to the wall via a first end portion so that the wall serves as a stop for goods on the belt, the wall being movable by means of a drive device and drive means (14, 15) between a first extreme position at or in the vicinity of an aperture to the loading space via which goods can be loaded onto and unloaded from the conveyor, and a second extreme position at a far end of the loading space from said aperture, and a second element which is disposed at or in the vicinity of the aperture to the loading space as a continuation of said first element of the conveyor and to which the goods-bearing belt is fastened via a second end portion which through at least one toothed strip cooperates with two elongate rollers (7, 8) forming part of said second element and supported for rotation in the loading space at a distance from one another and about which, during movement of said transverse wall between said extreme positions (A, B), said goods-bearing belt is unwindable and windable, so that the instantaneously uppermost strand of the goods-bearing belt wound about the rollers serves as a movable loading and unloading surface for goods between said rollers, and whereby at least one of said elongate rollers (7, 8) is drivable in rotation by the drive device for moving the transverse wall via the drive means (14, 15), which from said transverse wall run to said far end of the loading space and therefrom to the drivable roller and from said drivable roller back to said wall, between said extreme positions (A, B) and thus at the same time unwind or wind the goods-bearing belt. a first element comprising a goods-bearing belt and a wall disposed transversely to the driving directions of the conveyor, the goods-bearing belt being fastened to the wall via a first end portion so that the wall serves as a stop for goods on the belt, the wall being movable by means of a drive device and drive means (14, 15) between a first extreme position at or in the vicinity of an aperture to the loading space via which goods can be loaded onto and unloaded from the conveyor, and a second extreme position at a far end of the loading space from said aperture, and a second element which is disposed at or in the vicinity of the aperture to the loading space as a continuation of said first element of the conveyor and to which the goods-bearing belt is fastened via a second end portion which through at least one toothed strip cooperates with two elongate rollers (7, 8) forming part of said second element and supported for rotation in the loading space at a distance from one another and about which, during movement of said transverse wall between said extreme positions (A, B), said goods-bearing belt is unwindable and windable, so that the instantaneously uppermost strand of the goods-bearing belt wound about the rollers serves as a movable loading and unloading surface for goods between said rollers, and whereby at least one of said elongate rollers (7, 8) is drivable in rotation by the drive device for moving the transverse wall via the drive means (14, 15), which from said transverse wall run to said far end of the loading space and therefrom to the drivable roller and from said drivable roller back to said wall, between said extreme positions (A, B) and thus at the same time unwind or wind the goods-bearing belt.
