装置。 In a crane configured to raise and lower a lifting device by means of four lifting operation ropes that are fed out from a lifting operation drum and pass through the four corners of the lifting device, it is installed so that it can swing freely around a fixed main swing axis. A main oscillating body, a main cylinder that controls the oscillating position of the main oscillating body, and an opposing part of the main oscillating body that is equidistant from the main oscillating axis are oscillated about an axis parallel to the main oscillating axis. First and second rocking fulcrum bodies that are movably provided, and first and second sub-swivel bodies that are movably provided on each rocking fulcrum body about a sub-swing axis that is perpendicular to the main rocking axis. interposed between the rocking body, each rocking fulcrum body and each sub rocking body supported thereon,
first and second sub-cylinders that control the swinging position of each sub-swinging body, and each of the above-mentioned elevating and lowering A hanging tool attitude adjustment device for a crane, characterized in that the feeding end of an operating rope is tied together.
