Abstract: An arrangement for the electrical operation of a door of an aircraft, in particular an electrical drive arrangement for the operation of cabin doors of commercial aircraft. The object of finding a new option for operating the doors of aircraft which guarantees an electrical operation of the door with high reliability and a minimum of weight is met by an arrangement for the electrical operation of a door of an aircraft by providing an electrically powered driven shaft for the operation of the door which is coupled to at least one lever arm of the door mechanism so that it rotates together with it and the rotation of which pivots the lever arm of the door mechanism by a predetermined angle.

Abstract: An elevator system for the vertical transport of payloads in an aircraft is disclosed. The arrangement of the elevator system provides for the vertical transport of payloads in an aircraft which permits low-noise, reliably operating conveying between different levels of the aircraft and reliable stopping in the loading and unloading positions. The arrangement is characterized by low maintenance and low weight, in that the drive system has at least one closed belt for driving and for receiving the load of the elevator cabin, which belt is guided at either end of the mast on deflection rolls and has, between the deflection rolls, at least one freely accessible belt portion oriented parallel to the mast for fastening the elevator cabin and for the movement of the elevator cabin along the mast. The deflection rolls and the belt are provided with teeth which are adapted to one another and the belt is pretensioned in a defined manner.

Abstract: An arrangement for conveying material to be conveyed along a conveying plane, in particular for freight-loading systems in freight compartments, preferably of aircraft is disclosed. The arrangement provides that driving material to be conveyed along a conveying plane, with which safe, reliable transport of the material to be conveyed is ensured with low wear of the conveying roller under widely varying operating conditions. This is achieved in that, in a drive unit, the conveying roller is connected to a first drive and an associated first activating unit for producing a requisite traction force for moving the material to be conveyed along the conveying plane.
