The solution for rail track girders fastening

The GANTREX® surge connector, or tie-back, is an answer to the ever present problem of cracks and breaks at joints between girders and columns.

The transfer of side loads from track girders must happen through a girder-column link, which allows relative displacement.

The GANTREX® surge connector allows longitudinal stress transfers along with movements due to the flexing of girders : rotation and translation.

The surge connector eliminates diaphragms and the associated maintenance and repair costs.

Easy and secured installation.

 General characteristics
  • The GANTREX® surge connector consists of a steel plate provided with two spherical bearings in hardened steel, ensuring a low friction coefficient and requiring no maintenance.
  • The bearings can allow a rotation up to 5 degrees due to girders defelections, which, taking account of the length of the surge connector, is always compatible with relative movements inherent in building structures.
  • The surge connectors are supplied with O-rings, which protect the bearings by preventing dirt entering the joint.
  • The GANTREX® surge connectors fit easily in the global design of the building.

GANTRY’s complete range of surge connectors sizes and admissible loads can comply with installation requirements.

The GANTREX® surge connectors can be supplied pre-assembled complete with their fixing support.
