Marine propulsion


Modern ships, such as ferries and tugboats, are now equipped with rudder propellers in the drive area. They can therefore be used ideally in harbor basins as well as offshore.

Depending on the ship type and use, the propellers operate in the center or rear section of the ship's hull. To ensure that the latest ship building requirements are met, the rudder propellers should provide the ship with excellent maneuverability. This requirement can only be met by having the widest operating range possible around the propeller's own axis. State-of-the-art rudder propellers have an operating range of up to 360°.

Since ships are in the top price range in terms of investment, all of the components should fulfill their purpose fully upon delivery. This also applies to the rudder propellers described above. R+W heavy-duty safety couplings are used in mobile test rigs to provide protection against damage. Only the coupling's TÜV certified +/- 5% precision makes it possible to fulfill the customers' exact test requirements. The durability and maintenance-free properties of the safety coupling are an additional benefit.
