Recycling of tram switches
Worn-out tram switches are recycled and manufactured and then reused in existing routes. This extends their lifecycle. Non-destructive tests are completed for the worn-out parts, and then overlay welding is performed, and the parts achieve geometric properties, comparable to the geometric properties of brand-new parts through a follow-up mechanical processing. The wear resistance on the rolling surface is improved with the overlay welding of the restored details. Unsuitable details are substituted with new ones. Spare parts for tram switches are produced as well. The recycled switches can be used in the tram depots.
