slewing drives which are mainly applied in single or dual axis solar tracking systems, construction vehicles, port machinery, modular vehicles and small wind power systems.
　　Slewing drives/reducers are being chosen by customers home and aboard for PV/ solar thermal tracking systems due to the combination of slewing ring with the hourglass worm shaft, which provides more tooth contact, increased drive torque and smoother rotation. There are nine (9) different sizes available from 3” to 25” with more than 60 models to meet both regular and precise tracking requirements in PV, CPV and solar thermal power tracking fields.
