Summary:Compensation pulley of railway catenary. It comprises in principle a central body of greater diameter with a perimeter throat flanked by two circumferential teeth and two lateral coaxial drums where the cables of the catenary are coupled whose tension is compensated by the counterweight hanging from a cable that starts from the throat of the body of larger diameter. It is characterized in that the drums are axially encased with a certain degree of tightening in a bushing of the central body (1) of greater diameter, there being means of axial retention of such drums (2) with respect to the bushing and also means of rotational retention of the drums (3) of the said hub, achieving with all this a balance of the forces on the pulley.
