Elastic pad, manufactured from ethylene vinyl acetate (EVA) copolymer, is mounted between the rail foot and the steel sole plate.
The most important functions of elastic pad are:
- Distribution of the load over a larger surface.
- Elimination of point load and the fatigue ensuing from it.
- Absorption of contact inequalities between the rail and the supporting constructions.
- Reduction of noise and vibration.
- Reduction of wear of the rail and the sole plate.
Thanks to a better distribution of pressure using the elastic pad is economically advantageous when determining the sizes of the support for the crane track. Moreover one may expect a load reduction for the supporting construction of at least 25% (DIN 4132 and CTICM recommendations).
Because of the excellent quality and our favourable experience Bemo Rail uses the following types:
-14003: For standard applications.
-07002: For heavy rail constructions (for greater tensile strength: see rail table on pages 10 and 11).
Length: 12 metres on roll.
Width: Any desired width.
Thickness: 6 mm.
In any desired size. Two sides can be provided with rubber noses.
Standard thickness: 6 mm. Other thickness possible.
