<p>The balloon crane system (B,B3) comprises a fetter cable-guided lifting body (1), particularly a balloon, and a cable system for captivation of the lifting body in its usage position unfolded by a constant lifting force. The cable system has a fixing element (20), which is arranged along a given latitude of the lifting body, and has four fetter cables (F1,F2), which on one hand uniformly engage on the associated periphery of the lifting body at the latitude distributed on the fixing element, and on the other hand are indirectly anchored to the ground (G) below the lifting body.</p> |
