MacGregor, a division of Cargotec, is offering the offshore industry a technology-leading fiber-rope crane, according to a Cargotec statement.
The crane has been developed by combining MacGregor`s offshore crane technology with the fiber-rope tensioning technology perfected by Parkburn Precision Handling Systems. The companies have entered into a cooperation agreement to combine MacGregor`s offshore crane expertise with Parkburn`s fiber-rope tensioning technology.
"MacGregor recognizes that by partnering with experts in specific technological areas, it can deliver solutions that exceed its own capabilities," says MacGregor`s vice president of R&D and Technology, Baard Trondahl Alsaker. "We see ourselves as being able to integrate the best technology available to deliver systems with technology-leading capabilities."

The new MacGregor crane features a simple-to-operate fiber-rope lifting system that uses Parkburn`s unique tensioning technology. The Parkburn equipment eliminates the heating and degradation problems associated with on-load fiber ropes stored on winch drums. Importantly, it can accommodate non-uniformities resulting from splices in the rope.
"This is an important advance for handling loads at depth," says Alsaker. "The great advantage of fiber rope in this context is that it weighs virtually nothing in water, so regardless of the length of rope paid out, it does not add anything to the load experienced by the crane. This is in complete contrast to the situation with wire rope, where the ever increasing weight of wire paid out, limits the load permissible in relation to depth."
