ONBOARD DECK CRANE EQUIPMENT, METHOD FOR CONTROLLING THE SAME, AND PROGRAM

摘要

PROBLEM TO BE SOLVED: To provide onboard deck crane equipment that can be operated more stably and efficiently, and provide a method for controlling the onboard deck crane equipment and a program.SOLUTION: Onboard deck crane equipment includes: a pair of deck cranes 2 respectively having a jib 22 provided across a hold on a deck and suspending a cargo, and a crane body 21 pivotable around a first axis line O1 moving upward from the deck and elevatably supporting the jib 22 around a second axis line O2 extending in the direction intersecting with the first axis line O1 in the upper end; a drive unit for turning the crane body 21 around the first axis line O1 and elevating the jib 22 around the second axis line O2; and a control device which controls the drive unit so that a relative distance between these jibs 22 may become larger than a predetermined value, when the pair of jibs 22 performs at least one of turning and elevation.SELECTED DRAWING: Figure 4
