Abstract
An apparatus for loading into and unloading objects from a ship has a horizontally displaceable support, a frame having a lower end, guides supporting the frame on the support only for vertical movement relative thereto, and a grab below the frame engageable with the objects. A mainly vertically extending cable is connected to the grab and vertically interengageable formations on the grab and frame lower end, when engaged together, arrest the grab horizontally relative to the frame. A winch or other drive is connected to the cable for reeling in and paying out the cable and thereby raising and lowering the grab relative to the frame lower end and bringing the formations into and out of engagement with each other.
