<p>The aim of the invention is to design a lower cable pulley of the forestry winch by which it is possible if necessary, to redirect the pulling cable (5) for lowering the gripping point of the pulling force by secure protection against undesired derailing of the pulling cable, in such a way that the bolt (10) featuring a designed head for manual grip and a cylinder-shaped stem including a groove (10.1) inside the stem is inserted into the stem through the openings of a thicker and thinner wall (8.1. 8.2) of the enclosure (8). A pin (11) tangentially inserted into the groove (10.1) of the bolt (10) supported by a spring (12) is guided in the opening approximately in the centre of the thicker wall (8.1) of the enclosure (8).</p> |
