PROBLEM TO BE SOLVED: To provide a detection method for a swing angle, a torsion angle and a falling angle of a crane capable of accurately detecting the swing angle, the torsion angle and the falling angle of the crane with long head used under bad environment. SOLUTION: Two pairs of acceleration sensors S1, S2 capable of detecting acceleration in xyz three-axis direction are arranged in a diagonal direction of a body part 6 of a grab bucket 5 respectively. The swing angle, the torsion angle and the falling angle of the crane are detected using the two pairs of acceleration sensors S1, S2. COPYRIGHT: (C)2006,JPO&NCIPI
