Lift system with a device for determining the position of the lift car using a code carrier and a code reading sensor system

摘要

An lift installation comprises equipment for determining a position of an lift cage (2) movable along a guide flange (21) of at least one guide rail (7), a code carrier (10) formed to be stationary over the length of the guide rail in the travel direction (8) of the lift cage (2) and a code reading sensor system (11) for contactless detection of the length coding of the code carrier. The sensor system is guided at the guide rail at a spacing (39) from the length code carrier (10) and is connected with the lift cage (2) by means of a mount (14) to be fixed in the travel direction (8) and to be movable in a direction normal to the travel direction (8). The code reading sensor system comprises a guide roller (31) which rolls on the guide flange.
