摘要

An elevator machine frame assembly (30), comprises a plurality of support plates (32) configured to support at least selected portions of an elevator machine including a traction sheave and a plurality of support rods (36) connected to the support plates (32) near ends of the support rods (36). The support rods (36) maintain a desired spacing between the support plates (32) and a desired alignment of the support plates (32). Each of the support rods (36) has an exterior body comprising at least one first material and at least one second, different material (44) on an interior of the support rods (36). The second material (44) may comprise a sound-dampening material for example sand.
