Capstan with unlimited cable stroke, characterized in that the cable is pressed radially in the throat of a driving pulley, along a determined arc of this pulley, by curved clamping jaws applied in turn on the cable by rollers under the effect of the load, arranged in such a way that they constitute a non-tense endless chain supported by guides and idle pulleys and that mesh with a denture fixed to the drive pulley so as to accompany the cable without relative slip and participate therein the motor pulley to the retention of a given fraction of the load, which allows the pulley, on the one hand, endless chain jaws, on the other hand, the semi-circular section throats that produce minimal cable wear.
