Rail Clips

Patented Solution

Whether it’s cranes traveling on rail or machinery moving on specialty tracks, our GANTREX® clips, combined with GANTREX® pads, constitute the essence of the industry-proven soft rail fixing system.

First, let’s set the basics: what is a rail clip?

Component used to attach the rail to the track supporting structure. Rail clips are typically made of metal and are designed to securely hold the rail laterally, while also allowing for some longitudinal movement and expansion due to temperature change and other factors.

Our clips are suited for every application that requires fixing a rail track:

All types of industrial overhead cranes and transfer cars systems
STS and automated portal cranes, stacker-reclaimers
Loaders and unloaders for bulk material handling
Automated stacker cranes for warehouse industry
Special heavy load applications such as retractable roofs and rocket movers

Our GANTREX® patented clips are at the core of our soft-mount crane rail solutions and can fit just about every rail profile available worldwide. Our clips maintain rails in position via a mechanical lock and, simultaneously, accept the real rail movements through a soft synthetic elastomer nose, vulcanize-bonded to the clips, designed to accommodate the forces applied to rails by cranes.

Lateral adjustment facilitates the installation and allows for further corrections to the track geometry throughout its life.

Designed as stress resistant, their mechanical performances have been certified and tested by worldwide renowned laboratories for the specialized Rail Tracks Construction.

RAILLOK™ INNOVATIVE DESIGN

Through the introduction of our patented RailLok™ clips and pads, Gantrex has literally rewritten the state of the art. This technology ensures active-contact between the clip and rail. With this patented feature of the Active Contact the use of impact drills is possible 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.

RailLok clips ensure the clips are installed properly against the toe of the rail and improve the dynamic load transfer to minimize clips backing off.

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.

RailLok™ clips are available in weldable and boltable versions for different fixing supports. The mechanical performances of the stress resistant clips were certified and tested by worldwide renowned laboratories for the specialized Rail Tracks Construction.

Weldable Clip

Boltable Clip

Weldable Clip

The welded clip comprises of two parts, the welded lower and adjustable upper part.  The lower part is welded to the steel support and the upper part is fixed to the lower part via captive bolt(s).  The self-locking wedge design of the clips keeps the clip bolts in tension.

Weldable RailLok™ clips feature the patented additional wedge via inclined bolt which ensures that lateral contact with the rail foot is maintained during installation. Moreover they allow the use of impact wrenches which permits faster and easier installation.

Weldable clips are available in different sizes and capacities to suit different rail profiles and wheel loads.  The correct clip selection not only depends on those dimensional and mechanical considerations but also on installation contingencies. We therefore recommend you contacting us to discuss YOUR requirements.

Boltable Clip

The RailLok boltable clip consists of two interacting elements which allow easy lateral 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. 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 not only depends on those dimensional and mechanical considerations but also on installation contingencies.
