These wheel-set turntables are used to automatically rotate a single wheel-set as part of an automated wheel re-machining center.
Used to re-direct the wheel-set on fixed rails in the workshop.
The turntables capture the wheel-set that is rolled onto it. The turntable rotates left or right at 90 degrees (as programmed) and then pushes the wheel-set onto the tracks - moving it on to its next position.
