ARTICULATED DECK-CRANES

The Author, of O & K Orenstein & Koppel AG, of Lubeck, briefly describes his company's articulated deck-cranes, designed for handling containers and other cargoes. This type of crane has either a fixed column or a portal; the top of the column or portal provides a pivot for a slewing horizontal arm, and the outer end of this arm provides a pivot for a second horizontal arm, and the outer end of this arm provides a pivot for a second horizontal arm which slews in a plane above the first arm. The outer end of the second arm supports a turntable containing the hoisting gear, to which the container spreader is attached (there are alternative arrangements for general-cargo handling and for grabs). As with quayside handling equipment, the container is carried horizontally in the athwartship direction while the turntable is automatically kept parallel with the ship's longitudinal axis (the turntable can also be moved into any position by the crane-driver). The view from the crane-driver's cabin, and the telescopic spreader used, are such that no helpers are needed in the ship or on the quay. For small ships with one hatch, the crane could be mounted on a column at one side of the ship. Larger ships could have more than one crane, mounted on columns at the ship's centreline, or they could have a portal-mounted crane capable of serving all holds including the foremost; the crane is particularly suitable for this latter arrangement. The article gives some further information on these articulated cranes, and includes tabulated data and performance curves for two types, one with 25 and the other with 35 tonnes container-handling capacity; six alternative outreaches, varying from 16 to 36 m according to the model, are listed for each type. The article also gives brief information on a telescopic arrangement for the attachment of the load in order to avoid difficulties due to ship motions when handling cargo in a swell or seaway.
