Line guiding system for at least one supply line which can be coiled and uncoiled and rotary guide therefor 5 The proposed line guiding system (600) for at least one heavy and/or rigid line, for example a power cable for shore-side power supply for a ship (alternative maritime power), has a winding device (602) which is rotatable about an axis of rotation (A) for 10 coiling and uncoiling the line (610) and a rotary guide (106; 206; 606) for the line from a first point (F) to a relatively rotatable second point (R). The rotary guide has a helical guiding course having first helical layers (117; 257), in which the line is wound about the axis of rotation (A), and second helical layers (118; 15 258), in which the line is wound in the opposite direction. A return curve (119; 259) connects the two helical layers. According to the invention, the rotary guide (106; 206; 606) has a tubular support sleeve (140; 240; 640; 130; 230) which is coaxial with respect to the axis of rotation and serves to support the 20 helical layers radially outwards or radially inwards. Furthermore, a rotary decoupling structure is provided, by which helical layers (117; 257, 118; 258) supported on the support sleeve are decoupled from the winding device (602). 25 (FIG.4)
