METHOD AND DEVICE FOR CONTROLLING HOISTING OPERATION OF ON-BOARD CRANE

摘要

PROBLEM TO BE SOLVED: To enable a craning work such as the excellent dynamic lift-off and horizontal drawing works while suppressing the rolling of a ship without adding any large facility. SOLUTION: A derricking boom 18 and a hoisting apparatus for hoisting a cargo hung from a top of the boom control the hoisting operation by an on-board crane mounted on a barge 10. The target horizontal distance and the target boom top height from the longitudinal metacenter ML for preventing the rolling of the barge 10 are obtained, the boom derricking angleθB in the hoisting operation is adjusted so as to maintain the target horizontal distance, and the hoisting speed of the cargo is adjusted so as to maintain the target boom top height.
