  • Crank Shaft

    Crank Shaft

    A crankshaft is a device that converts the up/down movement of piston from engine explosion to rotational movement to drive the propeller shaft. Large crankshafts manufactured by Doosan Heavy Industries & Construction consist of a crank throw, main journal, flange journal and thrust shaft that are separately manufactured and integrated into a single body using the Shrink Fitting Method for final assembly. The company manufactures the forged products for large and low speed engines.

  • Marine Shaft

    Marine Shaft

    Marine shafts are categorized into propeller shafts and intermediate shafts, with variations in the quantity and type of shaft depending on the size of the ship. A propeller shaft is assembled with propellers, and intermediate shafts may be assembled together with a crankshaft so that rotational movement can be delivered to the propeller shaft to drive the propellers.

  • Stern Forge Product

    Stern Forge Product

    Doosan Heavy Industries & Construction boasts the largest production capacity of stern forge products, and has a history of manufacturing integrated-type stern forge products weighing up to 210 tons. The rudder horn and stern boss, or stern frame cooling, are key parts of a ship’s steering and propulsion system, and are installed at the stern, so they are generally categorized as stern forge products.
    A rudder horn is used to fix and support a rudder, part of steering apparatus of a ship. The rudder horn is directly connected to the rudder stock and pintle, forging products of Doosan. A stern boss supports the propeller and propeller shaft of a ship, enabling it to move.
