and/or the second guiderail mount includes one or more dampers disposed between the car guiderail and the frame. ### Claim 9 (depends on 4) The elevator system of claim 4, further comprising one or more tension member terminations connected to the beam laterally between the first and the second beam ends. ### Claim 10 (depends on 1) The elevator system of claim 1, wherein the frame extends laterally between a first frame end and a second frame end; the second guiderail mount includes a first mount leg and a second mount leg; the first mount leg extends vertically and laterally away from the car guiderail to a first mount leg end that is connected to the first frame end; and the second mount leg extends vertically and laterally away from the car guiderail to a second mount leg end that is connected to the second frame end. ### Claim 11 (depends on 10) The elevator system of claim 10, wherein the frame houses a first sheave bearing at the first frame end and a second sheave bearing at the second frame end; and the first mount leg transfers a vertical load between the car guiderail and the first sheave bearing, and the second mount leg transfers a vertical load between the car guiderail and the second sheave bearing. ### Claim 12 (depends on 1) The elevator system of claim 1, wherein the second guiderail mount includes a tab that connects the car guiderail to the frame. ### Claim 13 (depends on 1) The elevator system of claim 1, wherein the second guiderail mount includes a rail that connects an end of the car guiderail to the frame. ### Claim 14 (depends on 1) The elevator system of claim 1, wherein the second guiderail mount further includes a linkage that connects an end of the rail to the end of the car guiderail, and the linkage at least partially reduces transmission of vibrations between the rail and the car guiderail. ### Claim 15 (depends on 14) The elevator system of claim 14, wherein the linkage includes an outer shell and an isolation sleeve; the outer shell houses and supports the isolation sleeve; and the isolation sleeve includes a first aperture that receives the end of the rail, and a second aperture that receives the end of the car guiderail. ### Claim 16 (depends on 1) The elevator system of claim 1, wherein the frame extends laterally between a first frame end and a second frame end;
