Hanger supporting of a suspended contact wire of a supply electric aerial railway line and an electric aerial railway line comprising said hanger

A hanger for a supply electric aerial railway line comprising a contact wire, against which a railway vehicle pantograph rests, in use, the hanger comprising:

• a fastening member adapted to be fixed to a supporting element,
• a metal supporting frame coupled to the fastening member;
• a fastening terminal adapted to couple to a portion of said contact wire,
• a member movable with respect to said supporting frame in opposite directions in a first direction in the presence of an external disruptive action transmitted to the contact wire by the fastening terminal during transit of the railway vehicle pantograph,
• a mechanical friction damper associated with said movable member;
• and an elastic device interposed between said fastening member and said terminal and configured at least to attenuate said external disruptive action;
• the elastic device comprising a first elastic element compressed between said movable member and said fastening terminal and a pair of second elastic elements adapted to exercise, on said movable member, an action along a second direction transverse to said first direction;
• wherein in that said second elastic elements constitute elastically deformable parts of said supporting frame and in that the hanger comprises coupling rods for directly or indirectly connecting said movable member to said elastically deformable parts of said supporting frame, wherein the hanger further comprises a guide extending along said first direction and stably connected to said supporting frame, thereby defining a fixed guide relative to the supporting frame;
• said movable member being movable along said guide in opposite directions.
