IP66 Self Locking 9 Inches Vertical Slew Drive For Single Axis
Solar Tracking System
SLewing Drive Description
IP66 vertical mounted slew drives are specifically designed for
solar tracking systems that require horizontal axis tracking. The
precise rotation of the vertical slew drive allows the mechanism to
track perfectly. This kind of vertical slewing ring drive is
manufactured using the latest technology which incorporates
hourglass mechanism.
The vertical slewing drive is generally installed perpendicular to
the ground and is widely used in various photovoltaic power
generation projects, such as trough power generation, flat single
axis solar tracking system, tilted solar tracking system. PE (high
precision VE) series slewing drive is with high precision, usually
this model with enclosed housing, it can prevent dust and water
from entering the inside. If customer intends to use solar
panels,its can handle 18-30 ㎡ solar panels area.

Applications
The use of cost-effective, large-load rotary drive device and
mechanical linkage structure has the advantages of low cost and
high reliability. Applicable to mid-latitude regions, the power
generation efficiency can be effectively improved by more than 25%.
The closed-loop tracker principle combining astronomical algorithms
and sensors is adopted to effectively improve the tracking
accuracy. The main rotating parts use polymer material bearings,
which have the advantages of wind and sand resistance and
maintenance-free. It has various operating modes such as rainy day,
snowy day mode, strong wind protection, etc., to protect the safety
and stability of the bracket. The system capacity and angle are
flexible and adaptable to various terrain requirements.
