DEPP  ®

DEPP rail fastening system has been developed for the conditions of heavier static and dynamic loads on the concrete light rail and tram tracks. Owing to the placement of a steel plate between two specially shaped elastomers, by fitting an elastomeric spring on the anchoring screw and use of well-proved elastic clip Skl-1, it transmits vehicle load from the rail to the concrete foundation extremely well and with a high reduction factor. Thanks to specially shaped elastomeric elements on key fastening locations, it lowers vibrations transmission and reduces noise level extremely well. The fastening system is dismountable and all its elements are replaceable and recyclable.  DEPP is distinguished for the following advantages:

   • It demonstrably supports loads over 10.000.000 tons/year for over 7 years without any need for maintenance

   • It reduces shock and vibration and lowers noise level for 3-5 dB as compared to other fastening systems

   • It reduces force transmission from the rail to the concrete foundation

   • Excellent positioning of the track – recurring rail replacement is possible without fastening system demolition

   • Track paving is possible with any known paving system

The DEPP rail fasteners can be fitted directly (1) on the pre-constructed concrete foundation by means of anchoring screws and the levelling layer of rigid or elastic material, which is appropriate for track repair, or inversely (2) with special anchoring elements and subsequent construction of the concrete foundation. Based upon long, past experience, DEPP doesn’t involve any maintenance; therefore it can be categorized as an "INSATLL AND FORGET" system type!
