ABSTRACT:
A single head capstan winch comprises a capstan head which is movably arranged on a supporting frame for being guided relative to a pressing roller and is also rotatably arranged on this supporting frame and provided with a dynamically balanced surface of a shape that complements the enveloping surface of a multiplicity of windings of a cable or rope of the winch to thereby obtain a load-controlled clamping force necessary for the hauling-in of a load by means of the forward extending portion of the cable or rope the rearward extension of which runs off free of any load from the capstan head.
