Small resistance bar-spring clips

Small resistance bar-spring clips is a special elastic bar that can provide small longitudinal resistance in the railway track fastenings system. In the seamless line of viaduct track, the use of small resistance elastic bar can reduce the interaction force between rail and bridge, reduce the additional force of rail expansion caused by temperature change, train load and other factors, thus reducing the stress deformation of rail and bridge and extending its service life. Ensure the safety and comfort of train operation
