Tramway switches with flexible blades
Block switches, produced for both right and left diversions, can be used as facing as trailing. They are designed for use in the most demanding conditions of tramway tracks. Switches guarantee a high level of passage safety, quiet function, ecologically harmless and a long lifetime with minimum requirements for maintenance. The switch is made of grooved rails of the profile required by the customer (NT1, NT3, 60R2, 60R1, 73C1, Ph37, NP4, RT62, etc.). Both curved and straight switch blades of the switch are welded – rail part is from rail profile and quality requested by customer and flexible part is from rail of wear-resistant material. Both rail and flexible parts are welded by flash-butt welding method. The weldments forming the basis of the switch (stock rail profile, other steel profiles) are welded to the underlay steel sheet along the entire length. The half-switch rails (stock rails) are tightened to the sides of the frames by M24 bolts. The rail parts of the blades are tightened to the underlay steel sheets by M24 bolts or welded and their position is fixed.
Switches with flexible blades ensure:
- In cooperation with the facing or trailing setting system an automated or manual setting of the switch blades into the required direction and thus a safe tramway train passage in the straight or branching direction
- The switch construction enables the use of modern, unified setting devices with the setting and checking rod.
