ARI's WEA series slewing drives feature a modular design, simple structure, and convenient manufacturing and maintenance, with an IP65 protection rating.
The WEA series slewing drives are primarily used in slewing structures of engineering machinery, wind power generation equipment, and heavy-duty marine booms, where high torque transmission and compact structures are required.
