Installation Type

Transom installation

Transom installation is one of the three installation types .It is used for ships and vessels whose space of engine room are smaller, such as floating cranes,passenger ships,inland and coasting vessels etc.A mounting plate with sealing is fixed on the plate.That is,the upper of theRudder Propeller is fixed on the pin axis,and the lower is clamped on the pushing ring.When releasing the thrust bearing,the propeller can easily be elevated backwards.
Elastic suspension for special Sound Proofing is available for this mode of installation.

Well installation

The well installation is especially suitable for tugs,ferries,well station,floating dock and survey ships.
The SJMP Rudder Propeller is mounted in the well.The stem length varies with the requirement of the application.The top mounting plate of the well should,if at all possible,be above the waterline so that the Rudder Propeller can be installed and removed when the ship is floating.
Well installation varies with the distance between the Rudder Propeller and the diesel engine.When the engine room is very small,the Rudder Propeller can be near to the diesel engine and suitable for application in long-range transmission between diesel engine and rudder propeller.

Deck installation

  Deck installation is a complete propulsion package.It is a reliable and compact propulsion plant.The chassis carries the totally enclosed propulsion system.The power of the diesel engine is transmitted to the rudder propeller through an elastic coupling. a hydraulic clutch and a universal shaft.The chassis is constructed with a hydraulic system,an electric control box,daily fuel tank and so on system units.Installation is fast and simple because they are essentially self-con-tained.Only to connect the minnimum hoses and cables can make it available to obtain thrust.The desk installation unit merely has to be mounted and bolted onto afoundation of deck.Rudder propeller is mounted at the rear chassis.
  The rudder propeller can be mechanically or hydraulically raised or lowered in vertical direction by means of a depth adjustmen facil-ity.this serves to ensure maximum propeller thrust at all vessel draughts by maintaining the correct propeller thrust at all vessel draughts by maintaining the correct propeller immersion.
  For maintenance purposes,the rudder propeller can be pivoted out of the water to the rear hydraulically or mechanically by hand.
