Using Gantrex patented pads underneath a crane rail delivers real performance benefits. For example, both rail and plate are rolled elements and small imperfections exists on their surfaces, if a rail sits directly on the plate it creates point loading on the imperfections resulting in high stress concentrations. By inserting a rubber layer in-between the rail and the steel surface, the small irregularities of the material are absorbed and you create a much better load distribution, which in turn leads to a reduction in the stress on the foundation level. Gantrex in-house R&D has conducted extensive testing and structural analysis to understand how the use of pads reduces the stress concentration within the rail as well. And the results are clear : the pad ensures that local overloading is better distributed over the surface of the rail. This allows for load transfer through the centerline of the railhead and rail. In addition, a pad also provides a better load distribution in case of a misalignment, and a protection to the upper surface of the girder from abrasion and wear.

The integrated steel reinforcement allows to pull the rubber via extrusion during production process, and it also prevents lateral pad movements under standard operating conditions.
