NPC “Springs”, a United Wagon Company member, has launched serial deliveries of its high-strength springs for locomotives and metro coaches to Transmashholding (TMH).
NPC “Springs” has shipped the first batch of springs for the locomotive spring suspension to the 3 companies of Transmashholding: “Novocherkassk Electric Locomotive Plant” (manufacture of main-line and industrial electric locomotives), “Bryansk Machine-Building Plant” (manufacture of shunting and main-line diesel locomotives) and “Metrowagonmash” (manufacture of metro coaches and diesel trains).
The high-strength springs made by NPC “Springs” will be installed in a wide range of main-line electric locomotives and diesel locomotives, along with metro coaches. The technical characteristics of the supplied springs ensure a better performance. Compared to the springs of previous generations, they withstand 10 times more tension/compression cycles demonstrating 10 time smaller compression and significantly (up to 40%) higher permissible operating stresses. This is achieved due to the application of high-temperature thermomechanical treatment of steel and uniform coil-to-coil quenching.
“Starting to collaborate with Transmashholding we have made another step forward in the development of our production. We have earlier supplied springs to equip the trucks of Lastochka, a new generation high-speed train, which has been a positive experience,” Sergey Krivosheev, CEO at NPC Springs said.
