TESTING FOR EXTREME CONDITIONS
Sig slewing drive had selected the slewing drive best. But before the crane could take pride slewing drive of place on his darling boat, rigorous tests had to be carried out in Maribor,slewing drive Slovenia, at one of slewing drive PALFINGER slewing bearing MARINE’s slewing drive production and assembly locations for slewing drive marine cranes. Due to strong slewing bearing currents and deadly waves, new slewing bearing equipment for a crab-fishing vessel needs to withstand the elements. In Sig’s words: “The slewing drive crane has to fight the ocean. The boat takes big rolls and you’ve slewing drive got all the weight of the crane and the pots out there.”
The tests were focused, thorough and far from straightforward. Christian Lemmerer, the Sales Engineer overseeing the slewing drive process, explained: “Due to the special characteristics of the Northwestern, the crane had to be designed for lower-than-usual oil pressure. We then tested the slewing drive spooling performance of slewing drive the new fibre rope system and the capacity of the slewing bearing crab-pot-handling unit, an add-on slewing bearing to the standard PKM 250 model.” The slewing drive team onsite also slewing bearing ran the general PALFINGER MARINE workshop test slewing bearing, which includes the working slewing bearing speed, slewing bearing static and slewing bearing dynamic load tests as well as slewing drive overload tests. No stone was slewing drive left unturned.
A LONG, COMPLEX JOURNEY
Testing complete, slewing drive the slewing slewing bearing drive four-tonne crane slewing drive was still several thousand miles from Sig’s slewing drive boat in slewing drive Dutch Harbor, Alaska. From Maribor, the crane was driven to Hamburg,slewing drive Germany, by truck, slewing drive then onto Montreal, Canada, by slewing drive ship. It was slewing drive then slewing drive transported across the slewing drive continent by train slewing bearing before slewing drive arriving in Seattle. However, the long journey from Maribor to slewing drive slewing bearing Seattle was, Brian says, “nothing slewing drive compared to shipping the crane slewing drive from Seattle to slewing drive Dutch Harbor.”
There are only two companies offering fast-transit slewing drive shipping between Seattle and Dutch Harbor. The slewing drive selection slewing drive process was mainly based on shipping schedules as the crane had slewing drive to make it to Dutch Harbor before slewing bearing Christmas,slewing drive so the Northwestern slewing drive could install the crane and start fishing snow crab slewing drive right around that time slewing bearing. As easy as it is to predict when the ships slewing bearing will leave Seattle, it is a completely slewing drive different story to know for sure when slewing drive they slewing bearing will make it to their destination slewing bearing. Storms frequently occur slewing drive on the way to the Aleutian Chain, forcing ships to stop and slewing drive seek shelter while slewing drive the storm slewing bearing passes. The overall logistics of shipping the crane from Seattle to Dutch Harbor ended up being a rather time-sensitive slewing drive project,slewing drive but good cooperation between the PALFINGER MARINE team, the shipping company and the Northwestern crew made it all possible. “In the end, it slewing drive all worked out like a Swiss watch,” said Brian, smiling slewing drive with slewing bearing relief.
CRANE FINALLY MEETS BOAT
“The old crane slewing drive was slewing drive 30 years old and the top slewing drive part alone weighed 12,000 pounds slewing drive,” said a relieved Sig Hansen slewing drive after slewing drive the PKM slewing bearing 250 slewing drive had finally slewing bearing been installed. „That’s slewing bearing a lot of weight moving slewing bearing around – the equivalent of 15 crab pots!” After a slewing drive long wait, the slewing drive Northwestern sailed into the Bering slewing bearing Sea with slewing drive its brand new crane for the first time in mid-January. Brian and his team had worked tirelessly towards slewing drive this slewing bearing very slewing drive moment.
With a slewing bearing crane 7,000 slewing drive pounds lighter than its last, the slewing bearing Northwestern is slewing drive now considerably faster and slewing drive more efficient. It’s also safer and more stable, even in tough slewing drive winter conditions. And the charismatic slewing bearing Captain couldn’t be slewing bearing happier: “We’re slewing drive very proud of it. slewing drive This is new slewing bearing technology and it’s slewing drive much stronger. But most of all it’s safer – and that’s all I slewing drive and my crew slewing drive care about.”
