ABSTRACT:
A lifting hook is arranged to grab an object to be lifted by a cylindrical lifting surface formed thereto, the lifting hook having a hook shank, a hook part joining the hook shank and a locking device arranged to lock the lifting hook to the object to be lifted. To allow the lifting hook to be reliably attached to the piece to be lifted, a mechanical control device is mounted above the hook part to co-operate with the upper surface of the lifting surface for guiding the hook part to a lifting position onto the lower surface of the lifting surface.
