Applications

The copolymer pad Valex VX1 has been specifically developed for elastic laying of crane rails on discontinuous support. The Valex VX1 copolymer pad, when used jointly with the fastenings systems of the Valex series, reduce significantly stress and wear of the rail and of the mechanical components of the crane. It also helps to achieve an even distribution of the load on the supporting structure. The use of the copolymer pad is suggested above all in the following situations:

  • the rails are subject to heavy working conditions;

  • the rails are subject to high vertical and,or lateral stress;

  • the rails are operating in extreme weather conditions;

  • noise and,or vibrations shall be reduces to the minimum.
 
Technical specifications

The Valex VX1 pad:

  • is manufactured with strain and wear resistant synthetic copolymer;

  • even in the extreme operating conditions, the pad does not misplace laterally;

  • is not damaged by oil, grease, ozone and by the exposure to ultra-violet rays;

  • reduces significantly noise and vibrations;

  • greatly reduces load concentrations and fatigue stress;

  • eliminates uneven contacts between rails and the support structure;

  • protects the crane mechanical components and reduces the wear of wheels, bearings and axles.

 
Technical and physical specifications of the elastomer:
  • Hardness: 90° +/-5 Shore A Din 53505
  • Tensile strength: 13 N/mmq Din 53455
  • Extension: 280% Din 53505
  • Permanent deformation: 5% (max.) A 23°C
  • Working temperature: - 30° to 80° C
  • Noise reduction: 10% DbA
  • Vibration reduction: among 30 et 40%
  • Lengths available: on request
 
Assembling instructions:
Before laying the pad, the supporting area shall be clean and free of oil, grease and every jut or unevenness, which could damage the pad.
