Vibration protecting rail fastening systems CRADLE
WHAT FOR?

Reducing stiffness of vibro protection construction of track lower than 10 kN/mm leads to breaching of track widening and rail canting.

Reducing stiffness of vibro protection construction of track lower than 10 kN/mm leads to breaching of track widening and rail canting.

Reducing stiffness with using CRADLE down 2 kN/mm doesn't leads to breaching of track widening and rail canting.

  • Considerable vibration and noise reduction on the operating lines and those under construction.
  • Reduction of the dynamic impact on the track base.

 

 
WHY CRADLE?
  • An unattainable earlier rail elasticity of 2.5 kN/mm has been reached while preserving the lateral rail  stability;
  • Absence of friction parts.
  • Convenient replacement of resilient elements.
  • A quick installation on operating lines.
  • Vibration reduction, similar to structures of the “mass-spring” type under standard rail fastening envelope.
  • Rail stress reduction.


Experience with CRADLE

          The Pushkin Museum                                                       Shilova Gallery
          2005 year. CRADLE-2                                                       2006 year. CRADLE-2
        

    Track construction under the museum is wooden sleepers planted into the track concrete. Works on installation of 1250 vibro-isolating  fasteners took approximately one month. Efficiency in the frequency band 31.5 Hz reached 8 dB in the frequency band 63 Hz - 12 dB.




          The Bolshoy Theatre
         2011 year. CRADLE-2MD
        

        Track constructions in tunnels, located near the Bolshoi Theatre are wooden sleepers planted in the track concrete. Works on installation of 4000 fasteners took 2 months. Vibration protection average efficiency of Bolshoi underground rehearsal and concert hall reached 8.3 dB on the “A” scale considering 31.5 and 63 Hz octaves, where subway trains vibration signal was detected.
