Method for retensioning overhead wire assemblies of rail-bound traffic

The invention relates to a method for retensioning overhead contact line systems of rail-bound rail traffic, wherein fastening and tensioning devices with cable pulls and slot guides are attached to an overhead contact line mast or a wall. The invention is based on the object that by means of a path-dependent tensioning force of the longitudinal chain work, migration of the chain work in one direction is prevented, an equilibrium state is achieved, the design effort is reduced, and theft is prevented. According to the invention, this is achieved by using a self-centering retensioning system with a nonlinear force progression via spring elements, a special eccentric disk or a special slot guide, wherein the system is set such that the force increases or decreases when the center point of the support rope suspended between two overhead contact line masts moves away from or toward the retensioning system, wherein F i x = Σ a j x j + f i is, and F i - tensioning force on the wheel tensioner, f i - tensioning force per tensioning device at rest (system is centered), a j - parameter which is dependent on the desired force progression, x - deflection overhead line from rest position, i - number of the wheel tensioner mean, and f i = f 1 - f 2 is.
