Abstract: A load bearing tension member for an elevator system includes a plurality of tension elements arrayed across a tension member width. The tension elements are offset from a tension member central axis, the central axis bisecting a tension member thickness and extending across the tension member width. The tension elements include a plurality of fibers extending along a length of the tension element, and a matrix material in which the plurality of fibers are embedded. A jacket at least partially encapsulates the plurality of tension elements.

Abstract: A unitized segmented sheave assembly is provided. The unitized segmented sleeve assembly includes sheaves arrayed in a side-to-side formation and respectively comprising bearings and an exterior running surface and spacers interleaved between neighboring sheaves. Respective inner races of the bearings of each sheave and respective interior portions of each spacer cooperatively form an interior annular surface. The unitized segmented sheave assembly further includes a sleeve disposable in abutment with the interior annular surface.
