How to install a suspended load by a crane vessel

摘要

PROBLEM TO BE SOLVED: To provide a method of installing a hoisted load by a floating crane by which swinging of the hoisted load caused by oscillation of the floating crane can be reduced without using a complicated mechanism.SOLUTION: Hooks 21 suspended from each of jibs 11 and a beam body 23 extending to a direction parallel to the jibs 11 are connected to one another by a plurality of load suspending wires 22b, the hooks 21 suspended from each of the jibs 11 and a suspended load 24 are connected by a plurality of load suspending wires 22a which are arranged at an interval in the extending direction of the beam body 23 and positionally adjusted while vertically penetrating through the beam body 23, and the hooks 21 suspended from the adjacent jibs 11 are connected to each other by a rigid connection body 30 and the suspended load 24 is suspended by the jibs 11 so as to be moved to a predetermined position and installed.SELECTED DRAWING: Figure 2
