Method for installing a heavy lift crane system at a hoisting site. The crane system comprises a circular slew track assembly (1) extending over at least a slew arc about a slew center (2) and a crane (20) with a crane carriage configured to travel over the track arrangement, a main boom (40), a back mast (50), an adjustable length arrangement (60) between the back mast (50) and the main boom (40). The method comprises arranging a connector strut (80) underneath the horizontal back mast (50), pivotally connecting an upper end of the connector strut (80), pivoting the back mast (50) into an inclined raised position, arranging a counterweight (70) at the slew center (2), bringing the connector strut (80) into a substantially vertical orientation above the counterweight (70), connecting a lower end of the connector strut (80) to the counterweight (70), and raising the main boom (40).
