Thruster

The Kalkman rudder propeller is developed and produced by Kalkman Scheepstechniek. This system can be designed as L-Drive or Z-Drive.
With an L-Drive, the motor is placed directly on the rudder propeller. With an Z-Drive a right-angle gearbox is mounted on the rudder propeller, from this gearbox you can work with a cardan shaft or flexible coupling to a diesel or electric engine. 

The rudder propeller can rotate 360 degrees, this ensures that you can maneuver optimally in all directions. 

Steering can be done hydraulic or electric. 

Our systems can be driven by diesel engine, hydraulic motor or electric motor. 

Optionally we deliver a nozzle.

• Can be rotated 360 degrees
• Optional integrated rudder for extra course certainty
• Suitable for continuous use
• Diesel, electric, hybrid or hydraulically driven

Tunnel bow thruster type Bèta

The propeller, which is installed vertically in a round tunnel, supplies propulsion to starboard or port. This is the most effective bow thruster in terms of yield/propulsion per kW.

Beta spits

The Spits is an advanced version of the bèta bow thruster. Suction and propulsion in this P-SB bow thruster take place at the bottom of the ship, which means it can also be used in shallow waters.

Channel thruster type Delta

They are characterised by a horizontal propeller, which sucks up water from under the ship and uses a revolving thrust drum to thrust it through one of the tubes.
