摘要

Mechanism to achieve the self-alignment of the variable position pulleys, characterized by the provision of a mobile pulley mounted on an adjustable support, which is rotatable on a fixed axis in a sliding support on an axis parallel to the winding drum of the traction cable driven by said pulley and by another of variable position; through whose foresight it turns that the tension of the cable itself, determines the self-alignment of both pulleys and their free rotation with total disappearance of friction in the flanks of their throats and elimination of risks of wear both in the latter and in the cable itself, during the translation of said mobile pulley to ensure the correct winding of the cable.
