Abstract
A modular, prefabricated elevator includes column-like guide modules (10) extending between a foundation module (13) and a head module (2) and attached to a building by fastening modules (11), and an elevator car (5) that is connected by support cables (3) with counterweights (9) running in the guide modules (10). A stationary drive for the car (5) is in the form of one or two drive modules (12) combined with the head module (2) or with the foundation module (13) and integrated into the modular system in this manner. Through appropriate selection of the number of drive modules (12), the mode of suspension and the motor power, a wide range of use is covered with respect to conveying load and speed.
