As an essential part of an overhead catenary system, Galland’s tensioning devices have been developed since our early years of activity. After being approved as supplier of the SNCF, we have continuously worked on developing and extending our product range. Currently, we propose tensioning devices using two technologies :

  • Mechanical : wheels, spring or winch, with or without grease
  • Hydropneumatic : with AERO 480 and AERO 1000

We offer options such as anti-fall systems and measuring rulers.
