摘要: A passenger conveyor (20) includes a handrail assembly (30) comprising a handrail (32) having a plurality of co-extruded polymer materials (34, 36). In one example, an outermost portion (34) establishes a passenger gripping surface (38). One example includes an extruded soft, low cost polymer in the middle of the handrail cross section to reduce cost and weight. A disclosed example includes a toothed driving surface (40) on an inner side made of a selected one of the polymer materials (34, 36). In one example, the driving surface (40) and the gripping surface (38) comprise the same polymer material.

摘要: A load bearing assembly (20) includes a plurality of tension members (22). A joint in the load bearing assembly (20) has a staggered pattern of discontinuities (30) in the tension members (22). A stress relieving feature is associated with at least outermost tension members (22A, 22L) in the vicinity of the discontinuities. One example includes supplemental tension members (32, 50) as the stress relieving feature. Another example includes selected spacings (32′, 40, 42) between ends of at least some of the tension members. One example includes different sized tension members as the stress relieving feature. Another example includes different lateral spacings between selected tension members.
