Jib cranes for use in offshore wind parks

Jib cranes for use in offshore wind parks
Reliable technology that defies the elements

For the efficient maintenance and smooth operation of offshore wind farms, jib cranes are indispensable.
Permanent operational readiness is absolutely essential for getting the technicians with their equipment and
spare parts from the supply ships to the wind mill´s foundation in case of need. This places high demands on the construction
and structural design of the cranes.

Extreme conditions call for extreme quality consciousness.
At sea, the weather affects technology 24 hours a day, even at sunshine. Our design engineers responded to these
extreme weather conditions by selecting only high quality materials for jib cranes, screw jacks and winches.
The encapsulated design keeps the system ready for action. Special protective coatings make our equipment
seawater resistant and guarantee the function.

Corrosion - we have the answer.
Like offshore wind farms, our engineered products such as cranes, lifting tables, screw jacks and winches are designed
for a service life of up to 20 years. In order to withstand the continuous, climatic impact at high sea,
the highest quality standards apply to construction and processing. The corrosion protection plays a crucial role:
Bearings and joints are encapsulated. In addition, all surfaces are sealed with a special protective coating rendering
salt water, sea air and contaminations by bird droppings.

Technical details

  • Lifting capacity up to 5,0 t
  • Lifting speed up to 40 m/min
  • Coating according to corrosiveness category C5-M
  • Use of sea-water resistant materials
  • Certification of the crane by all accredited institutions such as Germanischer Lloyd, TÜV, Det Norske Veritas or Lloyd's Register

 


The crane is available in different configuration levels. For the mechanical model, lifting, boom adjustment and swivelling are controlled manually. You also have the choice of a partial electrification of individual components. Besides ease of handling, the all-electric model offers two additional advantages:
1. In case of damages and maintenance works there is no risk of contamination of sea water by leaking hydraulic fluids. The components can be operated in the sense of “Green Energy”. Thus, the wind power plant and the maintenance facilities complement to a harmonious ecological and economic overall concept.
2. 40% lower maintenance costs are an important argument for electromechanical systems compared to hydraulic systems.
