The invention is directed to an elevator system for the vertical transport of payloads in an aircraft. The object of the invention, to find a novel possibility for the arrangement of an elevator system 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 and which is characterized by low maintenance and low weight, is met, according to the invention, in an elevator system for aircraft 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, wherein 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, and one of the deflection rolls communicates with a drive motor which has a large torque and can be well regulated, wherein the drive motor, apart from its driving function, is also provided for braking and holding the elevator cabin load.

Elevator system for the vertical transport of loads in an aircraft

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. There is a second drive having an associated second activating unit for producing an adequate pressure force of the conveying roller against the material to be conveyed, and control electronics part is provided, which coordinates the two drives, which can be activated independently of one another, as a function of a motion state of the material to be conveyed. The motion state is detected at least by the internal sensor unit, is designed as a self-testing device.
