Fully functional model of a 6-axle railway crane with a movable telescopic boom. The crane can operate independently or, after manually unlocking the gearbox coupling, can run in a train formation. The upper carriage can rotate 360° without any stops. All rotation and lifting movements feature soft start and stop. This allows for playful lifting of bridges or laying of switches and track sections. The horizontally positioned boom is suitable for working under overhead lines. The telescopic boom can be tilted and extended in any working position, even with a load on the crane hook.
