To properly transfer the lateral forces from the rail into the steel plate or structure the rail needs to be secured in the lateral direction by appropriately sized clips. The clips also need to properly mitigate dynamic loads without backing off the rail. Gantrex RailLok clips incorporate the new and patented active contact technology which slightly tilts the bolts during clip installation ensuring the clip properly engages with the tow of the rail. The Active contact within the clip also improves the clip performance under dynamic applications ensuring clip stability which means the clip stays engaged with the rail longer without backing off.
Clip spacing and clip sizing is extremely important for the best performance of the system as a whole. To minimize pad creep we need to minimize lateral rail movement, this is done by properly sizing the clips and ensuring proper clip spacing. Clip spacing is normally calculated to keep lateral rail deflections within allowable parameters specific to your application. It is also extremely important to ensure proper performance of the clips under dynamic loads, if the clip backs off the rail and the rail is allowed to move the in the lateral direction then pad creep will persist. Gantrex Active Contact RailLok Clips are the industries leader in securing the rail under dynamic applications, the clips engage with the rail for longer minimize the possibility of pad creep.
