HANGING POSITION DETECTION DEVICE AND HANGING POSITION DETECTION METHOD OF FLOATING CRANE

摘要

PROBLEM TO BE SOLVED: To provide a hanging position detection device and a hanging position detection method of a floating crane capable of easily attaching a GPS antenna to a floating crane such as a self-propelling grab hopper barge, and capable of measuring an accurate position of a tip of a jib.;SOLUTION: A hanging position detection device of a floating crane 1 includes: a GPS antenna 11 removably fixed to an arbitrary position of a crane turn part 3; position and direction measuring means for measuring a position and direction of the GPS antenna 11; jib elevation angle measuring means for measuring an elevation angle β of a jib 4; and calculation means for calculating a position of a jib tip part 4a on the basis of the position and direction of the GPS antenna 11 acquired by the position and direction measuring means, the jib elevation angle β acquired by the jib elevation angle measuring means, a relative position of the GPS antenna 11 to a turning center C of the crane turn part 3, a GPS antenna fitting angle, the length of the jib 4, and a horizontal distance between the base end of the jib and the turning center C.;COPYRIGHT: (C)2015,JPO&INPIT
