The crane has a crane boom provided with a guy system for controlling a load lifted by the crane, such as a wind turbine rotor blade in a horizontal orientation. The cable system comprises a guide cable (10) and a cable assembly comprising a cable (15), a cable winch (16) and a traveling block mounted to the guide cable for traveling along the guide cable. The stay wire system further includes a repositionable cross-member (30) configured to be mounted to and project from the crane boom. The cross member provides support for the guide cable at a location spaced from the crane boom. The repositionable cross-member is mountable along the crane boom at a selected one of a plurality of mounting locations (25-28).
