Electric Point Machines
Our Company has been involved in the design and manufacture of electric point machines since the first machine was manufactured in 1922. Even today, we continue to refine the basic NS-type electric point machines, for improved reliability, performance and maintainability. Numerous models tailored to diverse installation environments have been developed. We will continue to develop new electric point machines, making them lighter and more compact, requiring less maintenance, to ensure that our machines meet the needs and situations of customers.
