ABSTRACT:
A method of installing roller guides in an elevator system so as to be centered on their respective T-rails. In the case of an elevator using either and active or semi-active roller guide system, the method uses the position transducers that are part of the roller guide to indicate how to reposition the roller guide after it is loosely bolted and approximately positioned on the elevator car. For an elevator not using an active roller guide or semi-active roller guide, the present invention temporarily attaches position transducers to the roller guide before bolting the roller guide to the elevator car. These position transducers are removed after centering the roller guide on the T-rail.
