The slewing drive is a new type of slewing product, usually called slewing ring, which is usually composed of worm, slewing ring, housing, motor and other components. Since the core components are slewing bearings, they can simultaneously withstand axial forces, radial forces, and overturning moments. Compared with traditional rotary products, the new rotary drive features easy installation, easy maintenance and a greater degree of installation space.

Compared with traditional rotating products, the spherical worm wheel rotary drive has the advantages of simple installation, easy maintenance and more space saving.The product can be widely used in the field of construction machinery and new energy, such as heavy plate transporter, container crane, truck crane, aerial working vehicle, solar power generation system and so on.
