Application
The enclosed housing slewing drives are widely used in the different engineering application such as heavy loader transporters, harbor mobile crane, ship lifting, claw trucks, container lift crane, and movable gantry cranes, mine machine, excavator, concrete machine, paper machine, as well as wind power generation system also use our slewing drive.
When a slewing drive is used in solar energy industry, users have to choose an ideal one according to the actual area of solar panels.
Generally, 3 inch slewing drive is suitable for solar power system coming with 3-5㎡ solar panel, 7 inch for 10-17 ㎡ solar panel, 9 inch for 18-30 ㎡, 12 inch for 31-45㎡, and 14 inch for 46-60㎡.
