The trains (be they transit or freight) do not stop running – so railway companies need dependable solutions that they can count on for maintenance.
The NSH Group (Niles-Simmons-Hegenscheidt) and its North American subsidiary NSH USA Corporation (Albany, New York and Sterling Heights, Michigan) are partners in that equation. With a complete product line of railway maintenance and production equipment, the NSH Group sets the standard worldwide. The key to the group’s prominence is a commitment to continuous improvement of its machines and practices.
The Simmons wheelset and bearing presses are utilised throughout the world to mount and demount wheelset components safely and efficiently. Regardless of the production goals and work piece requirements, the group manufactures a press to meet those expectations. The machines are designed for flat-floor installation, removing the need for a pit or special foundation and speeding up the installation process.
The lightweight tooling is customised for the end-user’s work pieces and is easily installed or removed during operation. Automatic and semi-automatic operation is possible through the intuitive controls.
Recent updates to the product line include an integrated measurement system. The contact precision measurement probes allow for high accuracy in an often unforgiving and rugged wheel shop environment. The system automatically measures radial and axial runout as well as wheel set back-to-back inspection.
The presses can also include an overhead positioning system that eliminates the need for manual operator-positioned devices for visual or electronic position feedback to mount components. All of the presses now come standard with an energy efficient and quieter on-demand hydraulic power unit. The design of the presses additionally accommodates a variety of automated or manual loading options.
Railways worldwide depend on Simmons’s AAR and APTA-compliant wheelset and bearing presses.
