Together with our sister company Hegenscheidt, Simmons Machine Tool Corporation offers underfloor wheel re-profiling technology with flexible solutions for a wide diversity of applications such as High Speed Trains, Heavy Haul Locomotives, and Light Rail Vehicles.
Simmons' ability to offer underfloor solutions based on lathe and milling technologies gives the customer a choice based on what's best for the particular railcar fleet. The Hegenscheidt Underfloor Wheel Lathes are available in both single and tandem versions. The U2000-400 utilizes fully automatic positioning, machining, and measuring processes. The U2000-400D is a tandem machine capable of machining two wheel set pairs simultaneously. The turning technology combined with CNC control and related setup automation makes it easy to change from one wheel profile to the next if required. The U2000-400 product line can be further automated and interfaced with the Argus® Wheel Set Diagnostic System which downloads key wheel measurement data directly to the U2000-400 control system removing any chance for 'operator error'.
The Stanray® Underfloor Wheel Truing Machine offers another concept in high performance, heavy duty underfloor wheel re-profiling utilizing full profile milling technology. The Stanray offers 'ease of use' and automatic machining cycles. Profile wear data is measured by an electronic wheel profile gauge which downloads the measurement data automatically into the Stanray's controls. The machine is utilized by heavy haul railways for locomotive maintenance as well as by heavy rail transit operators such as New York City Transit Authority and other railways throughout the world.
