Clamp Beam

The Pandrol Clamp Beam Balise Mounting System is used to install balises (transponders) into track securely and efficiently.

Balises are used as beacons on European train control systems to provide data through communication with train borne receivers. Their accurate positioning and secure fitting are vital to ensure the reliability of the safety critical data they transmit.

The Clamp Beam is mounted between sleepers on ballasted or slab tracks and is retained by clamping to the feet of the running rails. Its design ensures that balises are installed in a compliant position, significantly simplifying the installation process and saving time and money. The Clamp Beam has been developed to withstand the adverse track environment and has passed rigorous approval tests. Over 40,000 have been installed worldwide.

Technical Features


  • Easier to install, reposition, and remove than other products as there isn’t a need to drill into the sleepers, dig ballast, or carry out tamping, which saves time and reduces labour costs
  • Additional money is saved because track possession is eliminated or reduced
  • Significantly reduces lifetime ownership costs incurred from repositioning for verification trials and maintenance
  • No specialist equipment or power tools are needed for installation
  • Can be used in a wide variety of settings with various track formations, tie types, and balises, and can be installed directly to the rail foot
