ムの姿勢制御装置。 In a structure in which a hook block 7 is suspended from the tip of a boom 4 that can be raised and lowered by a boom cylinder 3 via a wire rope 6, the angle of the wire rope 6 with respect to a boom reference line A perpendicular to the axis of the boom 4 is detected. A detector 10 and a ground angle detector 9 for detecting the angle θ of the boom 4 with respect to the ground surface are provided, and from the angle detected by these detectors 10 and 9, the lateral deflection angle Δθ of the wire rope 6 with respect to the perpendicular line is calculated. A boom attitude control device for a crane, characterized in that at least one of the raising and lowering of the boom 4, the extension and contraction of the boom 4, and the hoisting and lowering of the winch 8 are controlled so that the obtained lateral deflection angle Δθ becomes approximately 0.
