Abstract
A counterweight is provided for tensioning the wire of a catenary in a railway line, comprising a metal shell (1) made up of a frame (1a) and a surrounding body (1b) which is filled with a filler material (2), which integrates at least high-density concrete in combination with a metal material as an additional filler for increasing the density of the counterweight. The frame (1a) is embedded into the filler material (2) and in turn, is linked to the surrounding body (1b) by a welded joint.

Counterweight for tensioning a wire of a catenary in a railway line, which has an outer pull to be hooked to at least one end of the catenary wire, where:
- the counterweight comprises a metal shell (1) made up of a frame (1a) and a surrounding body (1b), which is filled with a filler material (2) that integrates at least high density concrete combined with a metal material as an additional filler for increasing the density of the counterweight;
- the frame (1a) being embedded into the filler material (2) while also being joined to the surrounding body (1b) via a welded join;
- characterized in that the frame (1a) comprises at least a main bar (3), which runs along the entire length of the counterweight, in addition to a number of crosspieces (4), which cross the main bar (3);
- where the ends of the crosspieces (4) are joined by welding to the surrounding body (1b) and where the crosspieces (4) are joined by welding to the main bar (3).
