CRANE DEVICE, WORK SHIP, AND WORK METHOD OF OCEAN WIND POWER GENERATION FACILITY

摘要

PROBLEM TO BE SOLVED: To provide a crane device which inhibits swinging of a moving object component relative to at least the crane device and thereby enables stable operation, and to provide a work ship and a work method of an ocean wind power generation facility.SOLUTION: A work ship 2 includes a base 21 for installing a crane device 1 for working on the ocean. The crane device 1 includes: a body part 11 which is disposed on the base 21 so as to rotate in a substantially horizontal direction; a gib 12 which is tiltably disposed in the body part 11; a guide reader 13 which extends in a substantially vertical direction and has an upper part connected with a tip of the gib 12; an extendable catch fork 14 where one end is connected with the body part 11 and the other end is connected with a lower part of the guide reader 13; and a hook 15 which is disposed so as to move along the guide reader 13.
