DHHI started to develop and manufacture core components for megawatt-level wind turbine from 2004 and has developed 15 kinds of core components for 1.5-6MW wind turbines, e.g. gearbox, yaw and pitch drives, nodular iron castings, etc., which have achieved batch production.
DHHI takes the lead in development and manufacture of polar crane in China, with a market share over 70%.
  • Mass-produced large gearbox for wind turbine, developed and manufactured by DHHI
    Gearbox for 6.2MW offshore wind turbine, developed and manufactured by DHHI
    Gearbox for semi-direct-driven wind turbine for both offshore and onshore purposes, developed and manufactured by DHHI
    Castings for 8-10 MW offshore wind turbine, developed and manufactured by DHHI

    Core components for wind turbine
    As a larger gearbox manufacturer for megawatt-level wind turbine in China, DHHI has developed over 10 series of gearboxes covering dozens of types with a total supply of more than 14000 sets which are widely applied in onshore and offshore wind fields both at home and abroad. The series gearboxes for 2.X MW, 3.X MW and 4.X MW wind turbines are of platformization design, which can quickly meet the customized demand of the customer. The product is stable in performance, high in reliability and exported to EU, South Korea, Japan, India, etc.
    DHHI established a yaw and pitch drives development center where international advanced design software is used to develop products that can meet the demand of different wind fields for 1-6MW wind turbines, achieving modularized, serialized and standardized production of yaw and pitch drives for different types of wind turbines.
    DHHI has a capacity for producing 100,000 tons of nodular iron castings for wind turbine annually. It has 8 casting lines, with the products (hub, elbow, base) covering 0.85-12 MW wind turbines, monthly production of more than 70 sets of castings for offshore wind turbine, and successfully developed and manufactured the castings for many types of wind turbines ranging 3-4.5MW, 5-7MW, 8-10MW, 10-12MW.

    800t stationary slewing crane for nuclear power plant, developed and manufactured by DHHI
    Refueling machine of fuel transfer system, developed and manufactured by DHHI
    Refueling machine for nuclear power plant, developed and manufactured by DHHI
    Lifting appliances for nuclear power plant
    DHHI takes the lead in development and manufacture of polar crane in China, with a market share over 70% and independent intellectual property rights for polar cranes for both improved 2nd-generation and for 3rd-generation nuclear power plants (incl. CAP1000, CAP1400, ACP1000 and ACPR+). It can provide 250/100+10t, 217(205)/10+190(205)+5t, 300/25USt, 320+35/5+600t,235/25t,320/25t and 200+35/5+550t polar cranes for 300,000kW, 1,000,000kW, 1,250,000kW and 1,750,000kW nuclear power plants and drafted China’s first industrial standard on polar crane--JB/T 12214-2015 Polar crane for nuclear power plant. Up to now, DHHI has supplied polar cranes for many nuclear power projects, e.g. Chashma Pakistan, Guangdong Ling’ao, Liaoning Hongyanhe, Guangdong Taishan, Zhejiang Sanmen, Guangxi Fangchenggang phase Ⅱ, etc. and the lifting appliances that can be provided by DHHI have covered those for nuclear and conventional islands, e.g. reactor building crane, fuel building crane, steam turbine building crane, pump house crane, hatch area crane, waste storage crane and stationary slewing crane for lifting heavy and large piece at the terminal, etc.
