The purpose of the present invention is to provide a method for controlling a crane, with which the position of a hook is automatically adjusted before lift-off. To that end, provided is a control method for controlling a crane where a freely-derricking telescopic boom 8 is provided to a swivel base, a main hook 10a is suspended with a main wire rope 14 from a distal end section of the telescopic boom 8, and a suspended load W is suspended on a main hook 10a with slinging wire ropes 100, 101, wherein post-slinging lift-off is preceded by a hook position adjustment control involving repeating: a first process where the control device controls so as to reel in the main wire rope 14 to a position where the main wire rope 14 is tensed; and a second process where the control device controls so as to move the distal end section of the telescopic boom 8 in the same direction of a horizontal direction component V2 of the movement of the main hook 10a in the first process.
