Setting the mast and adjusting the sail

Liebherr supplies offshore-certified, corrosion-resistant and heavy-duty hydraulic cylinders to raise and lower the sail mast and unfold and fold the two-piece wing sails.

Advantages of hydraulic cylinders:

  • DNV GL classification
  • Two-layer, high-density coating for excellent corrosion resistance, optimum sealing properties and maximum seal life
  • Flexible position measurement system
  • Pressure sensors and load holding valves
  • Cylinder emergency release valve
  • Leakage-free counterbalance valve
  • Reliable shut-off and pipe break protection

Did you know?

Liebherr Maritime offers a wide range of advanced port handling equipment, ship and offshore cranes, as well as digital solutions and expert consulting. With innovative cable- and cylinder-luffing cranes in various sizes, Liebherr provides tailored solutions for cargo handling in global ports and the offshore industry.

Emission-free operations in harbours

A significant share of total emissions in port cities come from ships and machines in harbours. To actively drive forward the reduction of emissions, Liebherr engineers develop most efficient solutions for hybrid drives and energy storage systems. Based on extensive research and testing, we address our customer´s challenges in the electrification of local operations.

Energy storage systems to cover “hotel loads” of ships: Applications used in ports or at anchor can be driven by fuel cells to reduce local emissions. Fuel cells have a high inertia reacting to load fluctuations, therefore applications with high peak loads require an energy storage system to cover for power peaks.

Local regulations for cities and harbours: Liebherr keeps up with the overall and regional developments in regulations for construction sites. Within projects, we can provide necessary information on recommendations for actions or specific laws.

Hydraulic power unit for supplying oil to hydraulic cylinders and slew drives

The hydraulic power unit is used to supply oil to the tilting cylinders, the slewing cylinders and the slewing drive. These actuators perform the movements to raise, adjust or enlarge and rotate the ship's sail. In addition, the power unit has various monitoring elements such as pressure, temperature, contamination and level sensors, as well as proportional valve technology on the lowering brake valves. This provides a high level of safety and ensures that the hydraulic cylinders and slew drives function perfectly. The hydraulic power unit is prepared for installation in a shipping container.
