retractable and tiltable rudder propellers

Our hydraulic rudder propeller, which is retractable as well as tiltable.
The hydraulic motor is inside the lower bulb housing, and is directly connected to the propeller shaft.
These are made of steel, and are fairly simply build, no driving gears sets and only a few bearings inside, for easy repair and need very little maintenance.
A hydraulic cylinder inside the mounting frame is mounted for the tilting function, and another hydraulic cylinder is mounted inside the colum, for the height adjustment.
All pipes etc. are inside the thruster and are not in contact with the water.
The rudder propeller has a free tilting system, so the thruster will tilt automatically when a collision occurs, also the propeller will stop immediately. The bulb is the heart of the thruster and is simple to dismantle from the thruster.
Steering is 180 degrees, done by a hydraulic cylinder inside the top of the frame.
Because the propeller is hydraulically powered, we also have forward and reverse, so also covering the 360 degrees steering.

advantages

The advantage of Hydraulics

  • Significant cost savings. Cheaper to purchase, cheaper to maintain and cheaper to repair.
  • Less damage. Because of No bevel gears, no drive shafts, special seal system. Equipped with shear pins, or even free tilting, very solid construction, even suitable for Arctic conditions.
  • Shorter delivery times. Thanks to an advanced production process.
  • Simple, quick and easy to assemble. Plug-and-play system, assembly without alignment. Can be installed at any height, even almost continuously submerged in salt or sweet water.
  • Choose for yourself where to install the engine.
  • Greater flexibility on-board. Besides the propeller, with a hydraulic power pack you can also power other systems, such as a crane, a winch,  or even a generator. As a result, you need less diesel engines to do the same thing.
  • Optimal manoeuvrability. From full steam ahead to full astern in 2 seconds. Quick steering, ideal for dynamic positioning.
  • Very compact, good performance, low noise level, can also run on bio-oil.

 

The advantages of a retractable system

  • Prevent damage. With the depth adjustment system, you can easily adjust the height of the propeller to differences in water depth or load, you can lift complete propeller.
  • Optimise performance. Better performance and lower fuel consumption due to optimal water flow.
  • Fully retractable. Even if the ship runs completely dry, the propeller remains undamaged.

 

The advantages of a tiltable system

  • Easy to maintain. Dirt or rope in the propeller? Damage? Because you can tilt the propeller, you do not need the services of a diver or dockyard. This saves you a lot of time and money.
  • Easy to operate. The propeller is tilted easy mechanical or hydraulic, with the press of a button.
  • Secure with sheer pin system. If you hit something, then the safety pins will break and the propeller will automatically tilt upwards, the bigger units even have a free tilting system, incl. propeller stop, to prevents any damage by collision under water.
