The crane is hoisted from the ground to the nacelle by operating a cable winch at ground whereby a cable extends from the crane to a roller at the nacelle and to the cable winch. A hoist block with the roller is arranged on a jib at a first hoist block position above a second hinge part of a crane base and extended in horizontal direction from the nacelle. When a first hinge part of the crane is positioned at a corresponding second hinge part of the crane base, the cable extends in a downward direction directly from the roller of the hoist block and through a central opening in a pedestal. After mutual connection of the first and second hinge parts, the hoist block is removed from its first hoist block position.
