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. 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.
