This complete product line, along with their reputation for quality and innovation, is no doubt the reason that O&K has maintained a full orderbook through 1989 and well into 1990.

Among the current orders for

O&K cargo-handling equipment are an order from Danyard A/S in Fred- erikshavn (Denmark) for 15 deck cranes with capacities of up to 36 tons for three reefer vessels, with an option agreement for an additional 15 H-type low compact cranes. Also

MAN GHH of Oberhausen, West

Germany, will receive three 25-ton- capacity single deck cranes for a

Soviet customer, with an option for three additional cranes.

The Bremer Vulkan yard gave

O&K a repeat order for four Gemini twin deck cranes for two new reefer vessels. Over 150 units of this FGH series are in operation around the world. They have a working capac- ity of 18 mt each in single operation, or 35.4 mt when in twin operation, with a 25.4-meter working radius.

For shipowner Egon Oldendorff (Liberia Inc.), O&K will supply three single deck cranes to the Hu- sum Shipyard in West Germany.

The multipurpose vessel is intended for combined passenger and freight transport. One of the single deck cranes will have a 32-mt capacity at a 17-meter outreach, one with 16 mt at 17 meters, while the third will be 5 mt at 15 meters.

For the last 25 years, O&K of

Lubeck has been a world leader in deck crane innovation. They succes- sively introduced the first and sec- ond generations of twin deck cranes, the Gemini tandem operation deck cranes, the first double-jointed cranes, the first slim (narrow tower) and the first high-articulated jib deck cranes. O&K has also led the industry in incorporation of elec- tronics, with remote and program- mable operation. These advances in deck crane design have made O&K the recognized efficiency leader in modern on-board cargo handling.

In 1989, O&K has gone ashore, literally, with the introduction of the Stack Lifter. By mounting ad- vanced double-jointed cranes shore- side, they have introduced an inno- vative modular concept to rational- ize and improve intermediate con- tainer handling. High capacity gan- try cranes in modern ports achieve high container handling rates, re- quiring more economical and effi- cient intermediate storage. Interme- diate storage allows unloading batches of containers as they arrive, passing them on more or less contin- uously, or storing containers, arriv- ing continuously, to be later taken out in batches.

The Stack Lifter systemizes the intermediate storage process. In modules, it allows fully or partially automated handling of the interme- diate containers. The advantage of the system is the simple and safe input of the storage space data through a fixed point, helping posi- tion the containers more accurately, which in turn results in higher over- all handling rates. The system is especially advantageous where 46 Maritime Reporter/Engineering News
