VE9 CE Vertical Slewing Reducer, IP66 Sealing For Roof Top Tilted
Solar Trackers
Vertical Slewing Reducer Description
High precision VE9 slewing drives enable active systems to track
the sun by adjusting to the Earth’s rotation relative to the sun.
Solar applications include photovoltaic (PV) trackers, heliostats,
solar troughs, concentrated photovoltaics (CPV), and stirling
engines. Our slew drives can be mounted horizontally, vertically,
and at tilted angles so an infinite number of orientations are
possible.
Slewing Drive have many types such as enclosed type, open housing
type, vertical type, dual axis type, high precision type, worm
drive type etc. slewing drive is based on the slewing bearing with
strong tilting moment torque and static self-locking function. Much
tooth contact surface is designed specially for driving high load.

Applications
Inclined single axis tracking system
The inclined single axis is suitable for the latitude higher than
30 degrees, and the latitude angle is compensated by the
inclination angle of the rotating axis. Then track the sun's
altitude in the direction of the rotation axis, so as to achieve a
better increase in photovoltaic power generation. Generally, the
power generation can be increased by 25% to 35% relative to the
fixed bracket.
