Single-blade tramway switches
Single-blade tramway switches produced for both right and left diversions can be used as facing as trailing, usually in special constructions (“fan track”, also called “harp” or “comb”) in depots. Single-blade switches 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.). The curved blade can be replaceable. Its position is secured with a tongue and groove connection; the bolt heads are secured against spontaneous release. The blade is in R260 rail quality or from abrasion-resistant special rolled steel. Blade free half-switch is constructed as the weldment of rail parts and the block rail 310 C1 in quality R260 quality or as a special weldment in more complicated rail constructions.
Single blade switches 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.
