发明名称 Crane cable attachment
摘要 A crane cable attachment for delivering and taking up loads through openings in walls and the like comprises a generally horizontal rail suspended from the crane cable. A load carrying carriage is mounted for movement along the rail, between a lifting position underneath the cable and a loading and unloading position towards one end of the rail. An elongate prop is pivotally connected to this end of the rail for movement between a position in which it may rest on the ground where a load is to be delivered or taken up and a lifting position folded under the rail. A counter-weight is provided at the other end of the rail to maintain it horizontal when both the prop and carriage are in the lifting positions.
