Title:
吊具の位置の測定方法および測定装置および吊具
Document Type and Number:
Japanese Patent JP7036443
Kind Code:
B2
Abstract:
To provide a measuring method and a measuring device which can measure a position in a horizontal direction of a hoisting attachment with good accuracy, and a hoisting attachment.SOLUTION: A hoisting attachment 1 comprises a pair of targets 4 which are arranged at an interval in a first direction x, which are installed in the hoisting attachment 1 in a state where a difference ΔH between positions in a vertical direction z of the targets 4 becomes larger from one end sides of the targets 4 toward the other end sides in a second direction y crossing at a right angle the first direction x. Laser light is emitted to the targets 4 from a laser distance meter 5 to obtain positional information on the targets 4, the difference ΔH between positions in the vertical direction z of the targets 4 is calculated from the obtained positional information to determine a position in the second direction y of the hoisting attachment 1 on the basis of the difference ΔH between the positions and to determine a position in the first direction x of the hoisting attachment 1 from the positional information.SELECTED DRAWING: Figure 6
