<p>A limitlessly rotatable directioning device (1) with a hydraulic motor driven sheave according to the invention is clamped pivotally into a console (5). Two hydraulic pipes (3, 4) leading from the hydraulic system for the supply of the hydraulic motors on the directioning device (1) are trained to the fixed part (6) of the console (5). The pipes (3, 4) of the hydraulic motors of the directioning device (1) are connected to the movable part (7) of the console (5), which rotates in the same way as the directioning device (1) for a limitless angle, namely a multiple of 360 degrees to the left or to the right.</p> |
