    Railway counterweight with adjustable mass designed to tension a cable of the catenary of a railway line comprising a monobloc counterweight constituted by a frame composed of a reinforcement and a tubular casing, filled with a material based on high density concrete, having the reinforcement a central shank that pokes through the frame to configure a shooter. It is characterized in that the monobloc counterweight (1) comprises a lug (12) and a positioning rod (9), parallel to the central rod (6), and in addition the counterweight comprises at least one shield (2) of cross section similar to the cross section of the monobloc counterweight (1), the shield (2) being removable and constitutes the variable mass of the counterweight. The central rod (6) and the positioning rod (9) extend the monobloc counterweight (1) a length such that they can house at least one shield (2). It reduces manufacturing costs, increases its useful life and gives it the flexibility to modify its load. (Machine-translation by Google Translate, not legally binding)

    a positioning slot (11). The positioning rod (9) fits into it, so that the rods (2) are prevented from lateral movement.
    The mounting of the rods (2) is done by fitting into the grooves (10, 11) of the roundabout
    (2) the central rod (6) and the positioning rod (9), and stacking them on top of each other. To stack them, the first wheel (2) is placed by fitting the central rod (6) in the central groove (10) and the positioning rod (9) in the positioning groove (11), resting it on the cover (8) of the monoblock counterweight (1), leaving the lateral movement of the wheel (2) impeded. The rest of rodelas (2) are placed supported on the previous one.
    The central rod (6) extends over the cover (8) with a length such that it allows stacking the entire load of rods (2) until the maximum design load is reached. This length also defines the length of the positioning rod.
    In this way the rounds (2) are confined in the structure of the counterweight. The rods (2) are preferably made of dense concrete.
    Finally, on the cover (8), next to the central rod (6), a lug (12) is incorporated to facilitate the manipulation of the counterweight with a crane. The lug (12) is a drilled plate that joins the cover (8) by welding or mechanically, screwed for example. In this way, while the crane holds the counterweight by means of the lug (12), the operator who installs the counterweight can attach the catenary cable to the handle (5) located at the end of the central rod (6), where it will definitely remain discontinued.
    This lug (12) also has the mission of preventing the central rod (6) from being deformed if a crane hooks the counterweight and lifts it starting from a horizontal position, such as in a packing situation, since, since the central rod (6) in this solution is longer and more slender than the corresponding one in the traditional monobloc solution, there is a greater risk that it may suffer permanent deformations with improper handling.
    The present invention should not be limited to the embodiment described herein.
