Elastic pad
Elastic pad, manufactured from ethylene vinyl acetate (EVA) copolymer, is mounted between the rail foot and the steel sole plate.
Functions
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.
References
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).
Sizes:
Length: 12 metres on roll.
Width: Any desired width.
Thickness: 6 mm.
Single plate:
In any desired size. Two sides can be provided with rubber noses.
Standard thickness: 6 mm. Other thickness possible.
