Stanray M2 Underfloor Wheel Truing Machine
The Stanray® M2 is an underfloor railway wheel truing machine for reprofiling wheel treads on passenger and light rail vehicles. Utilizing proven Stanray wheel profile milling technology, the M2 performs fully automatic measuring and cutting cycles while managing extreme wheel wear conditions. The machine’s centerless operation allows for quick and easy setup which does not require removal of bogie components or access to axle centers.
The Stanray M2 includes integrated automatic measuring systems that monitor the wheel location and measure diameter, width, and profile as well as wheel set back-to-back, back face runout, and radial runout on the tread. Final diameters, profile conformity, and other desired parameters are verified and sent to the customer’s data management system or stored locally. The connectivity of the machine also allows for optional remote diagnostics, which will keep your revenue vehicles safe and on track.
