The invention relates to a hinged cantilever for catenary-type overhead line systems which is designed as a triple-hinged element. According to the invention, the arm rod (1) is angled on the free end thereof and forms a cantilever arm (1b) on which a catenary wire clamp (6) which accommodates the catenary wire is displaceably mounted. For hinged cantilevers with steady bracing forces (C) directed toward the carrying element (M), the geometry of the coupling points (G1 and G2) of the top anchor (2) and of the arm rod (1), said coupling points being arranged on the carrying element (M), is selected with regard to the supporting forces (A, B) and to the applied loads (C, D, E) in such a way that, following the conditions of equilibrium, the horizontal supporting force (A) on the coupling point (G1) of the top anchor (2) on the carrying element (M) is greater than or equal to zero.
