Sleeper Pads for ballasted tracks
Sleeper pads improve vibration isolation, help to reduce stresses and wear on the ballast under the rails and improve track stability. They can be installed both in high-speed rail lines and in lines with high axle loads, as well as in existing standard gauge lines during repairs and retrofitting.
The sleeper pads are installed on the sleepers in the production process using an optimized bonding system. As a result, no additional work is required at the installation site. Installation is quick, unaffected by weather conditions and can be carried out with a minimum of service interruption.
Life Cycle Costs
The extent to which the use of sleeper pads alters the track geometry quality has been systematically recorded for several years. The results are continuously influencing development work. One observation is a lengthening of intervals between tamping work by a factor of 2 to 2.5 thanks to the use of sleeper pads. If one considers the tamping cycle as an indicator for the achievable service life of a track, longer periods between tamping work point to a significant lengthening of the life of the entire track bed.
In addition, if costs for operating complications that arise from track closures for maintenance work are considered, sleeper pads are an extremely economical investment, particularly on track sections to heavy loads.
Mass-spring systems
Bearings for mass-spring systems are used in applications in which there are extremely stringent requirements for protection against vibration and noise. Getzner's bearings materials for mass-spring systems are highly efficient in helping to protect residents living in the vicinity of railway lines from the effects of noise and vibrations. Effective isolation of vibrations also has a positive effect on the real estate prices of properties affected by vibrations.
Rail pads
Rail pads are elastic polyurethane mats which are installed directly under the foot of the rail. They have a defined stiffness and serve to increase the elasticity of the ballasted superstructure. The improved load distribution yields
greater passenger comfort and less wear on the superstructure. The increased elasticity has a positive effect on the wearing of superstructure components and rolling stock.
Getzner Werkstoffe offers an exceptionally wide range of rail pads for every required stiffness rating, from standard gauge tracks to tram tracks.
