Furthermore, it is designed to keep the interplay of forces under tight control so that the risk of deflection and the conse- quent stresses can be reduced.

To be able to position the superstruc- ture using the SyncHoist and one crane, a special hoisting frame was made. As

Van Vuuren explained, "By using the lifting frame, we were able to keep all the parts that we had constructed intact."

A total of eight lifting points were used. Four of these were provided on two heavy-duty beams on the underside of the superstructure, with lifting cables that ran through the superstructure. The other four cables were attached to the outside of the superstructure to keep it properly balanced. The double-acting hydraulic (lifting) cylinders of the

SyncHoist system were integrated into the four outermost cables. These cylin- ders allow both lifting and lowering cor- rections in each cable to be controlled precisely. These four cylinders, each with a capacity of 85 tons, were placed in the right position before the lift, so that a pre-loading was achieved. While lifting and positioning the superstruc- ture, the interplay of forces in the cylin- ders, and the movements, are monitored by sensors and a computerized system, and corrected if necessary, to the pre- defined values.
