Tramway switches with replaceable 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 can be replaced – they are fastened to switch body by four M20x1,5 bolts and their position is secured with a tongue and groove connection or by screw adapter with 3 bolts, called “S-Stoß”. The bolt heads are secured against spontaneous release. The blades are made in R260 quality or from abrasion-resistant special steels. 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 replaceable 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.
