摘要： A single sheave 4 rope winch 1 particularly suitable for use with an anchor warp 2. The sheave 4 is fixed on a shaft 5 rotatably mounted in a base 3 adapted for mounting on a deck of a vessel. An electric motor 6 operates through a gear-drive 7 to rotate the sheave 4 about a vertical axis. Warp feed-in and feed-out means 8 and 9 direct a warp 2 to and from the sheave 4. Warp guide means 19 control a warp 2 during its tracking about with or through the sheave 4, the guide means 19 including a fixed and shorter section 19a and a longer articulated arm 27 section 19b. The arm 27 is arcuately shaped to extend about a sector of the sheave 4 and is biased by spring 26 radially inward such that an inner face 24 thereof impinges onto a warp 4 tracking in that sector of the sheave 4. In a preferred embodiment the inner impinging face 24 of the arm 27 incorporates a compound curvature, the radius of curvature increasing toward a free end of the arm 27.
