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 telescopicboom 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 soas 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.
提供在吊离地面前对钩的位置自动地进行调整的起重机的控制方法。为此,控制方法对起重机进行控制,该起重机在旋转台设有起伏自如的伸缩臂(8),从伸缩臂(8)的前端部通过主钢缆(14)悬挂有主钩(10a),在主钩(10a)上通过挂环钢缆(100、101)悬挂起升载荷(W),该控制方法在挂环后且吊离地面前,具有反复进行第1处理和第2处理的钩位置调整控制,第1处理中控制装置进行控制以将主钢缆(14)转入直到主钢缆(14)紧张的位置,第2处理中控制装置进行控制以使伸缩臂(8)的前端部向与第1处理中主钩(10a)移动时的水平方向成分(V2)相同的方向移动。
