The cable winch can be shifted and/or moved at least partially substantially along the longitudinal axis of the cable winch. A crane, particularly a deep sea crane, has at least one such cable winch device. ## Claims ### Claim 1 Cable winch device (10), having at least one cable winch (20), at least one cable (30) being at least partially windable and unwindable on the cable winch (20), at least one means (40) for at least partially shifting or moving the cable winch (20) substantially along a longitudinal axis of the cable winch (20), at least one stationarily-arranged cable pulley (70) about which the at least one cable (30) is wound and with the cable winch (20) being shiftable or movable relative to a reference point (B) of the at least one stationarily-arranged cable pulley (70), and the shifting means (40) comprise means (60) for directly or indirectly measuring the shifting movement of the cable winch (20) with respect to the reference point (B) of the at least one stationarily-arranged cable pulley 70. ### Claim 2 (depends on 1) Cable winch device (10) according to claim 1, wherein the shifting means comprises at least one of linear drive means (40) and at least one guide (50). ### Claim 3 (depends on 1) Cable winch device (10) according to claim 1, wherein the cable winch (20) is movable or shiftable at least partially substantially in two directions along the longitudinal axis of the cable winch (20). ### Claim 4 (depends on 1) Cable winch device (10) according to claim 1, wherein the measuring means (60) is an electronic measuring means (60). ### Claim 5 (depends on 1) Cable winch device (10) according to claim 1, wherein the cable (30) is a steel cable (30) or a fiber cable. ### Claim 6 (depends on 1) Cable winch device (10) according to claim 1, wherein the cable winch (20) is shiftable or movable at least partially substantially in the two directions along the longitudinal axis of the cable winch (20) relative to the cable winch (70). ### Claim 7 (depends on 6) Cable winch device (10) according to claim 6, wherein the cable winch (20) is shiftable or movable substantially parallel to a rotation axis of the cable pulley (70). ### Claim 8 (depends on 1) A crane having at least one cable winch device (10) according to claim 1. ### Claim 9 (depends on 1) Cable winch device (10) according o claim 1, wherein the at least one cable winch (20) and at least one stationarily-arranged cable pulley (70) are oriented with respective axes of rotation (A, C) substantially parallel, and with the at least one cable pulley (70) stationarily-arranged on a plane (B) substantially perpendicular to the respective axes of rotation (A, C), the shifting means (40) are arranged to correct position of the cable winch (20) relative to a reference point located on the plane (B) to prevent an angle formed by the cable (30) and plane (B) from becoming excessively large, and the measuring means (60) measure shifting relative positions of the cable (30), cable winch (20) and cable pulley (70) with respect to one another and shifting movement of the cable winch (20) relative to the reference point located on the plane (B). ### Claim 10 (depends on 9) Cable winch device (10) according to claim 9, wherein said shifting means (40) include guides (50) and rails (52) on which the guides (50) are respectively mounted for movement in opposite directions. ### Claim 11 (depends on 10) Cable winch device (10) according to claim 10, wherein said measuring means (60) are mounted on the axis of rotation (A) of the cable winch (20) adjacent one of the guides (50). ### Claim 12 (depends on 11) Cable winch device (10) according to claim 11, wherein said means (40) for at least partially shifting or moving the cable winch (20) include a linear drive (40). ### Claim 13 (depends on 12) Cable winch device (10) according to claim 12, wherein said linear drive (40) is formed by at least one hydraulic cylinder. ### Claim 14 (depends on 1) Cable winch device (10) according to claim 1, wherein said shifting means (40) are arranged to maintain angle of the cable (30) and a plane (B) along which the reference point is situated, below a threshold value. ### Claim 15 (depends on 14) Cable winch device according to claim 14, wherein the threshold value falls between 0.5° and 1.5°. ### Claim 16 (depends on 1) Cable winch device (10) according to claim 1, wherein said shifting means (40) include guides (50) and rails (52) on which the guides (50) are respectively mounted for movement in opposite directions. ### Claim 17 (depends on 16) Cable winch device (10) according to claim 16, wherein said measuring means (60) are mounted on the axis of rotation (A) of the cable winch (20) adjacent one of the guides (50).
