Abstract

The mechanism works in conjunction with the winch drum (2) and a fixed guide (4) in a plane (7) perpendicular to the drum axis and equidistant from the drum end flanges (3). An elongated rope support (8) extends parallel to the drum axis (6) and between it and the guide, for an equal distance on either side of the central plane (7). The support is curved near the respective drum flanges, the curve shape being determined by a tangent. This tangent is perpendicular to the resultant of forces represented by the direction of the rope effort exerted on the support in a plane perpendicular to the drum axis due to the change in direction as it passes over the support and by the force parallel to the drum axis due to the change in direction of the rope (1d) from the guide in the direction of this axis.
