ABSTRACT:
To permit an increase of the maximum permissible load of a crane for heavy loads, in particular an offshore crane, some of the luffing wires for luffing in and out the crane jib (4), are extended by guy wires (17); to avoid the disadvantage that the frame (3) of the crane with tie-back system can not slew, the part of the luffing wires connected with the guy wires, on the one hand, and the part of the luffing wires not connected with said guy wires, on the other, form part of separate hoists (6, 5) which can be operated by separated winches (14, 13).
