Abstract
A stabilizing system may be utilized to reduce or eliminate sway of magnetic tape that is suspended in an elevator hoistway and provides a positional reference to an elevator cab. The stabilizing system may include a stabilizing mechanism fixed within a hoistway and a roller cam disposed on the elevator cab. The stabilizing system may include a telescoping member attached to a guide having opposing flanges that restrict movement of the tape. The telescoping member and the guide may be biased in an extended position, where the guide partially surrounds the tape. In a retracted position, the guide is horizontally spaced apart from the tape. When the elevator cab passes the stabilizing mechanism, the roller cam may force the guide and the telescoping member into the retracted position to prevent any contact between the stabilizing mechanism and components disposed on the elevator cab.
