Using Gantrex patented pads underneath a crane rail delivers real performance benefits
There’s lots of reasons to use a Gantrex pad under the crane rail.
For example, if the rail sits directly on the steel plate you’ll have a lot of high stress concentration and high stress point contacts between the steel and the rail. By inserting a rubber layer in-between the rail and the steel surface, you create a much better distribution of forces which in turn leads to a reduction in the stress on the foundation level.
Gantrex in-house R&D has conducted extensive FEA analysis to understand how the use of pads reduces the stress distribution within the rail as well. And the results are clear. Better contact stress means that the inclusion of a pad effectively moves the load from the edge of the rail to the centerline. This allows for load transfer through the centerline of the railhead and rail.
In addition, a pad provides protection to the upper surface of the girder from abrasion and wear.
