Abstract
An appendable elevator for the transport of persons and goods can be attached to an outside surface (2) of a wall (16) of a building (1) and includes a self-driven car (5) which runs on a pair of vertically extending guide modules (10). The guide modules (10) are attached at lower ends to a foundation module (12) and at upper ends to a shaft head module (13) to form an inherently stiff and transportable frame. Counterweights (18) are mounted in the guide modules (10) and are attached to the car (5) by cables (19) which engage deflecting rollers (14) mounted on the shaft head module (13). Fastening modules (11) are attached to the guide modules (10) and telescopically mount shaft doors (22). Drive wheels (7), supporting wheels (8) and guide rollers (9) as well as wiring and control equipment are mounted in and on the car (5) to form a prefabricated elevator system which is attached by extending the fastening modules (11) into contact with the building (1).
