WEA Series Slewing Drives

worm gear slewing driveWorm Gear Slewing Drives

The WEA Series is the optimized and upgraded version of the traditional WE Series slewing drive.

Features

  • Thinner, higher strength and full-sealed design for optimal outdoor use
  • Full-sealed design can prevent corrosion and damage cause by wind, sand and water

 

Application

WEA Series slewing ring drives are typically specified as rotation parts for construction equipment and solar array systems, both indoors and outdoors. Some example applications include:

  • Solar Tracking Power Station 
  • Arm Rotation for Crane Trucks
  • Aerial Platform Chassis Rotation
