An elevator system (20) includes multiple elevator cars (22, 32) within a hoistway (26). Counterweights (24, 34) are associated with the respective elevator cars (22, 32). Frangible buffers (40, 38) are associated with at least one of the elevator cars (22, 32), the counterweights (24, 34) or both. In a disclosed example, buffer activators (42, 39) operate to break at least a frangible portion of the frangible buffers (40, 38) to dissipate energy associated with a collision or near collision between the elevator cars (22, 32) or the counterweights (24, 34).
