Yaw Bearing Bracket Support For Wind Turbine Castings QT400 SJK-400 GGG40 FCD400
Yaw Base plate connect the Nacelle Head Carrier and Yaw Bearing Spacer in wind turbine .Hydraulic station , yaw drive and yaw drive and yawbrake are installed on Yaw Base Plate .
Guangda could provide different kinds of the large parts castings as customer's requirements .A wind turbine casting refers to components that are cast or molded to specifications all of which are then assembled to form wind energy systems. The components of wind turbines vary as per requirements, deployment area or location, type as well as required output size height and various other factors. The primary parts that undergo casting include axel pins, rotor hubs, and main carriers,yaw base plate etc .
