Product Description

WH12 heavy load worm drive slewing gear reduction for mounted truck crane drilling rig and aerial working platform

Slew 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 slewing drive features easy installation, easy maintenance and a greater degree of installation space.

Spherical worm gear reducer rotary drive device is a new type of rotary products, usually by worm, rotary support, shell, motor and other components.As the core part adopts rotary support and enveloping worm structure, it can reach multi-tooth contact, has the characteristics of large transmission torque and smooth operation, so it can bear large axial load, longitudinal load and strong overturning moment at the same time.

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.
