Hydraulic retractable / height-adjustable and tiltable rudder propellers

Are you looking for a system that will allow you to sail in shallow water without any worries? Or in areas with a lot of fluctuation in water depth? Do you want to be able to easily adjust the height of the propeller to the load factor? Or do you need a system that is resilient if the unit is grounded? In all these cases, a retractable rudder propeller is the ideal solution.

The hydraulic height-adjustable Hydro-Armor units combine the properties of a ‘retractable’ system particularly with the advantages of a hydraulic rudder propeller.

Please see below video for a short animation of the advantages.

The advantages of hydraulics

  • Significant cost savings. Cheaper to purchase, cheaper to maintain and repair.
  • Less damage. No bevel gears, no drive shafts, special seal system. Equipped with shear pins, very solid construction, even suitable for Arctic conditions.
  • Shorter delivery times. Thanks to an advanced production process and ample stock.
  • Simple, quick and easy to assemble. Plug-and-play system, assembly without alignment. Can be installed at any height, even entirely submerged in 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 fewer diesel engines to do the same thing.
  • Optimal manoeuvrability. From full steam ahead to full astern in 2 seconds. Quick steerage, ideal for dynamic positioning.
  • Super-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.
  • 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 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. This prevents any damage.
