Boltable Rail Clips

Patented Solution

The RailLok boltable clip consists of two interacting elements that allow easy rail adjustment.  The clip is fixed to the rail by means of bolt(s) inserted through the holes made in the steel support. Boltable RailLok™ clips feature the patented active-contact design which ensures that lateral contact with the rail foot is maintained during installation. Lateral adjustment is possible with the movement of the cam. They also allow the use of impact wrenches which permit faster and easier installations. Boltable clips are available in different sizes and capacities to suit different rail profiles and wheel loads.  The correct clip and bolt selection depends on dimensional and mechanical considerations and installation contingencies of your particular applications. We therefore recommend you contacting us to discuss your requirements.

RAILLOK™ Active Contact Feature

Through the introduction of our patented RailLok™ boltable clips and our pads, Gantrex has literally rewritten the state of the art. This technology ensures active-contact between the clip and rail.  With this patented feature it is possible to use impact drills as the bolt tilts during torquing to push the clip against the toe of the rail​, reducing installation time. The patented technology increases the clips capacity to address ever growing crane loads and provides a narrower design allowing operational and financial savings.

The Active contact feature of the RailLok boltable clips improves clip performance in dynamic applications and maintains clip stability by reducing the possibility of the clip backing off from the tow of the rail. The Gantrex RailLok Clip patent is filed under the following numbers across the world: US8205803B2, EP2173947B1, CN101720371B

As a truly global company, we have several clip production sites across the world, from EU-origin production to local US production where we are producing a range of “Made in America” clips. Whatever you need – we can accommodate for all local specifics.

The mechanical performances of the stress-resistant boltable clips were certified and tested by worldwide renowned laboratories for specialized Rail Tracks Construction.
