Signalling Equipment

Clamp Beam

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

Clamp Beam product overview

The Clamp Beam is mounted between sleepers on ballasted or slab tracks and is retained by clamping to the feet of the running rails.

Balises are used as beacons on European Train Control Systems (ECTS) 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.
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.

Product Information Sheet

Benefots of the Clamp Beam

Easy installation

The Clamp Beam is simpler to install, reposition and remove than other products. Eliminating the need for drilling into concrete sleepers, digging ballast and tamping saves time and reduces labour costs.

Money saving

Additional money is saved because the need for track possession during installation is eliminated or reduced.

Reduced maintenance

When balises are installed using the Clamp Beam, lifetime ownership costs incurred as a result of repositioning for verification trials and maintenance are significantly reduced.

Non-intrusive installation

No specialist equipment or power tools are needed for installation. The Clamp Beam’s simple, non-intrusive installation can be done using commercially available hand tools.

Compatible

It can be used in a wide variety of settings. It is compatible with a range of track formations, sleeper types and balises, and can be installed directly to the rail foot.

Technical features of the clamp beam

Compatibility

The Clamp Beam is compatible with a range of track formations and with Siemens, Alstom, Bombardier and Hitachi balises (although it is not limited to these balise types). It can be installed onto any combination of sleeper types and directly to the rail foot.

Resistance

It is shock and vibration resistant to EN50125-3. It also has high resistance to chemical and climactic changes.

Non-conductivity

The Clamp Beam’s non-conductive design ensures that it does not interfere with existing signalling systems.

Secure fastening method

Its proven secure fastening method comprises a glass reinforced plastic (GRP) beam with stainless steel clamp components.

Vertical adjustment

When installing the Clamp Beam, there is no need to modify the track or drill into concrete sleepers. It is installed using commercially available hand tools – no power tools are needed. Installation, repositioning or removal typically takes less than 10 minutes per balise.
