Spring, Dampen, Guide - Greater Safety, Comfort and Service Life
The GMT Group is a leading company in the railway vehicle sector, specializing in the development and manufacture of primary and secondary suspension systems, guidance and load-transfer elements for bogies as well as vibration-damping rubber-metal elements specifically designed for suspension and decoupling in the drivetrain of the undercarriage or bogie and for other aggregates. These products are essential for ensuring ride stability, derailment safety and comfort requirements in railway vehicles, as well as for reducing unwanted vibrations and structure-borne noise caused by operation, track irregularities and varying loads. Thanks to its extensive expertise in materials, development, and applications, the GMT Group delivers application-specific solutions that enhance safety, ride comfort, and the service life of railway vehicles. The products are designed for high dynamic loads and long service life, they make an important contribution to quiet, reliable, and low-maintenance railway vehicle operations.
Industry Experience
The GMT Group has many years of industry experience and extensive expertise in the development, manufacture and testing of suspension elements and air spring systems for the railway vehicle sector. Working closely with vehicle manufacturers, the company has developed numerous products and systems over the past decades that are successfully used worldwide in commuter or long-distance trains as well as in freight transport. Drawing on its extensive expertise in materials and development, GMT creates vibration control solutions to improve ride comfort, safety, and level control. The systems are designed for high dynamic loads and long service life, and their reliability and durability contribute significantly to the availability of railway vehicles. In addition, GMT supports the use of its products throughout their entire life cycle and assists operators and manufacturers in ensuring economical, safe and reliable vehicle operation.
Requirements
The GMT Group’s vibration-damping and suspension products and systems for use in railway vehicles must withstand high dynamic loads, varying speeds, different environmental conditions and varying track profiles, while reliably reducing vibrations and structure-borne noise. At the same time, they must meet high standards for ride comfort, ride safety, and level stability, even under changing load conditions. Furthermore, the products must have a long service life and high fatigue resistance, they must function reliably under a wide variety of environmental influences such as temperature fluctuations, humidity and dirt. GMT’s spring elements and air spring systems are therefore precisely designed for specified installation scenarios - which are often constrained by limited installation space - as well as for applicable railway and safety standards, they contribute significantly to the smooth, safe and economical operation of railway vehicles.
Solutions
The GMT Group offers a diverse, compact and proven product portfolio of vibration-damping and spring-loaded rubber-metal components and systems for railway vehicles. These include air spring systems, conical primary springs, axle bearings, layer springs, bushings, spherical bearings and ball joints, traction rods, torque supports and anti-roll bars as well as a wide range of lateral, vertical, and longitudinal transfer buffers. The portfolio is complemented by innovative products such as the further development of the hydraulic axle guide bearing HYDRALL® or the mountable elastomer wheelset shaft protector MERP HD. In addition to bogies and undercarriages, GMT products are also used for mounting under or on the car body as well as in the couplings between vehicles.
