F.A.Q.


Why and how to weld rails ?

  • Welded joints are recommended to avoid shock and vibration when crane wheels pass over the rail joints. This also eliminates the need for punching of holes on the rail ends and the need for splice plates.
  • Because the soft mounting system allows for controlled longitudinal movements, stresses due to thermal expansion are eliminated, allowing for long rail or track lengths.
  • Rail splice joints do not give a sufficiently tight and stiff link between rail ends.  Some overhead crane rails, such as DIN 536 rails cannot be joined with mechanical splices because of the shape of their profiles.
  • The butt welding of rails works best with the soft mounting system.  GANTREX has the experience of continuously welded rail lengths in excess of 1000 m or 3,200 feet.
