ABSTRACT:
An elevator system 10 includes an elevator car 12 with a plurality of roller guide assemblies 20 attached hereto. The roller guide assemblies 20 guide the elevator car 12 vertically within a hoistway along a plurality of guide rails 16. Each roller guide assembly 20 includes at least one resin stop assembly 50 to minimize vibration and lateral movement of the elevator car 12. The resin stop assembly 50 includes a resin spring 52 adjacent to a rigid container 54, both coupled between a roller wheel arm 26 and the roller guide base 40. The resin stop assembly 50 improves the ride quality of the elevator car 12 by selectively limiting lateral acceleration and velocity of the elevator car 12.
