Abstract
An elevator positioning system includes an optical tape, optical tape clips, and a sensor. The optical tape clips are mountable to various structures within the hoistway. A crossbar of the optical tape clips is located between a sensor and optical tape such that the sensor detects an interruption in the optical tape and signals the detection to an elevator controller. The elevator car can then be controlled to align evenly with the landings associated with the hoistway. Another elevator positioning system includes a sensor and a reflector clip assembly. The reflector clip assemblies are mountable to various structures within the hoistway. A reflector target of the reflector clip assemblies faces the sensor such that the sensor detects the reflector target and signals the detection to an elevator controller. The elevator car can then be controlled to align evenly with the landings associated with the hoistway.
