Title:
SUSPENSION POSITION MEASUREMENT DEVICE AND SUSPENSION POSITION MEASUREMENT METHOD OF FLOATING CRANE
Document Type and Number:
Japanese Patent JP2015134684
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a suspension position measurement device and a suspension position measurement method of a floating crane which can accurately measure the position of a suspension body such as a grab bucket without requiring mounting operation at a hight place in a floating crane such as a self propelling grab hopper barge.SOLUTION: A suspension position measurement device of a floating crane comprises: a scanning type laser distance meter 13 which is fixed at an arbitrary position of a floating crane 1, allows a laser beam to turn and scan within a desired scanning range, receives a reflection beam 12 when the laser beam is reflected by an object, and measures a distance between the object, and a scanning angle; distance meter position measurement means for measuring the position of the scanning type laser distance meter 13; distance meter azimuth measurement means for measuring a true azimuth of a desired direction with the scanning type laser distance meter as a base point; measurement object determination means for determining whether the object is a measurement object; and calculation means for calculating a horizontal direction center position of the measurement object.
