Abstract

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, wh…
