Abstract: A rotary load lifting hook device according to the present invention incorporates a remotely operable rotational driving device 11 provided on a hook block 20 on which a load lifting hook 1 is positioned vertically for rotation. The rotational driving device 11 and the hook block 20 are connected to each other by means of chain wheels 12, 13 provided respectively thereon. An endless chain 14 is held in meshing engagement with the chain wheels 12, 13 so that the hook block 20 may be driven to rotate by remote operation. Rocking motion, oscillations and so forth which take place with the load lifting hook 1 when a load is lifted may be absorbed by the endless chain 14 such that the load lifting hook 1 can be rotated with safety and with cetainty without causing overstrain with the rotational driving device 11 and the load lifting hook 1.
