Abstract
An appendable elevator system includes an elevator car guide structure having two column-like guide modules (10) on which a self-propelled car (5) runs. The guide modules (10) are constructed as a plurality of extruded lightweight metal tubular sections including planar running surfaces (16, 25, 29, 30) for contact with guide rollers (9) and wheels (7, 8) of the car (5), anchoring grooves (33, 34, 35, 36), guide grooves (31, 32) and a brake arm (37) formed on an exterior thereof. An interior of the guide module (10) receives a counterweight (18) guided by the guide grooves (31, 32) and a buffer (44, 45, 46) and is accessible for assembly and maintenance through a removable maintenance lid (43). The sections of guide modules (10) are connected with one another and with a foundation module (12) and with a shaft head module (13) by groove strips (40), connecting straps (41) and screws (42) which engage the anchoring grooves (33, 34, 35, 36).
