Run-flats for people mover systems

摘要

Run-Flat systems are mounted within a pneumatic tire and are designed to allow the vehicle, on to which the tire is fitted, the ability to continue operation at a reduced speed. For people mover systems this prevents disruption of a service and damage to the guideway and provides the convenience of being able to repair the tire at the central maintenance facility and, most importantly, it provides passenger safety. Different types of flat prevention products and Run-Flat systems aer available. These include, tires with foam or polyurethane fill, solid press-on tires and the various central support Run-Flat systems made from aluminum, rubber or a elastomer composite. The advantages and disadvantages of each type are discussed in this paper.
