O&K O&K of Lubeck, West Germany, has long manufactured deck cargo, floating, and terminal cranes. During 1989, O&K completed incorporation of the product line of PWH (PHB Weserhuette), another West German crane manufacturer acquired by O&K in late 1988. The PWH technology for offshore cranes, especially gives O&K an impressively broad line of cargo-handling equipment, including standard, slim, and low-profile level luffing slewing deck cranes, doublejointed and gantry deck cranes, a variety of fixed and gantry terminal cranes, through floating and, now, offshore cranes.
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 Frederikshavn (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-toncapacity 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 capacity 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 Husum 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 successively introduced the first and second 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 electronics, with remote and programmable 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 advanced double-jointed cranes shoreside, they have introduced an innovative modular concept to rationalize and improve intermediate container handling. High capacity gantry cranes in modern ports achieve high container handling rates, requiring more economical and efficient intermediate storage. Intermediate storage allows unloading batches of containers as they arrive, passing them on more or less continuously, or storing containers, arriving 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 intermediate containers. The advantage of the system is the simple and safe input of the storage space data through a fixed point, helping position the containers more accurately, which in turn results in higher overall handling rates. The system is especially advantageous where space is limited or at a premium, or where maximum through-put rates are desired.
POSI LOCK Posi Lock Puller, Inc.'s new Hydraulic Systems Division, Cooperstown, N.D., has introduced a line of hydraulic pullers designed to meet growing industrial needs.
