Main features of the Hunger Offshore Crane Cylinder are:

• Different corrosion resistant rod coatings are available, exactly adjusted to the application in variously extreme enviroments. (Ni/Cr layer, thermic sprayed Carbides and Oxides / Ceramic or Ultraplate Plus Coating)
• Critical Cylinder components related to corrosion are specially treated to optimize corrosion resistance.
• Stainless Steel Piping and Manifold Block are applied for safety and load control function.
• Equipped with wear-resistant Hunger Seal and bearing elements, It has low wear and friction with stick-slip free when the crane is operated.
• It's designed with high working pressure over 400 bar.

It's applied for safe lifting of products from drillship and other offshore rigs. It's able to minimize the risk of swaying loads in harsh weather conditions with the knuckle boom crane solution.
The lifted load in operation is under the permanant hydraulic control. The load control valve which is directly mounted at the special cylinder guarantees that there is no uncontrolled movement of main boom or kuckle boom arm.
A Typical Knuckle Boom Crane is operated with the 4 cylinders in total (2 knuckle boom cylinders and 2 main boom cylinders).
