Pitch Control Units
Type FR-ELC | Type FR-HP |
 |  |
| Fully reversible compact electrical pitch control unit with built-in thrust bearing. The pitch can be adjusted only at low shaft RPM and low propellerload. The pitch is controlled from the wheelhouse via a potentiometer. | Fully reversible hydraulically powered proportional pitch control unit. The pitch can be adjusted under full RPM and propellerload. This gives the opportunity to combine the pitch control and the engine control system to avoid overloading of the engine. An external hydraulic pump must run continuously to provide pressure for the unit. |
Type FR-HFC | |
 |
| Fully reversible system that has a flanged hydraulic cylinder, with hollow bored output shaft, which is mounted on the output flange of a normal gearbox. An O.D. box (oil distribution box) is mounted on the front end of the gearbox, and a double hydraulic pipe connects the system through the hollow output gear shaft. The unit is available from 800 HP to 3200 HP. Main data FR-HFC |
Type AISFor use with a reduction gearbox with built-in hydraulic pitch control, where the pitch can be set while the propeller rotates or with a normal reverse/reduction gearbox, where the pitch is set with a wrench while the propeller shaft is stopped. Not recommended for feathering design. | Type SEMIFIXVariable with pitch adjustment nut. The propeller consists of our standard head and blades. The pitch is adjusted by means of the nut on the tip of the propeller head when the vessel is drydocked. |
