SDE7 IP66 Solar Slew Drive, High Torque And Precision For Dual Axis Solar Tracking System
Product Description
There are many applications in which the slewing drive can be
utilized, primarily because it is perfect for applications that
require both load-holding power and rotational torque strength.
Typical slewing drive applications include but are not limited to:
solar trackers, wind turbines, man lifts, hydraulic machinery,
telescopic handles, digger s, lifts, cranes, drilling equipment,
military equipment, robotic system.
We have a wide range of slewing drive with output torque ranges
from 221 lbf.ft to 15800 lbf.ft.
Slewing rings with integral worm shafts are becoming increasingly
popular due to the simplicity of installation and are used in truck
mounted cranes, small wind turbines, access platforms, turntables,
solar tracking devices, satellite communication systems, and simple
materials handling devices. High precision and zero backlash units
are similarly applied in specific projects. In addition, we can
offer various electric and hydraulic motors and gearboxes to match.

Customized Services
1. Special design based on different applications and projects
2. Different types of motors could be matched, such as hydraulic
motors, stepper motors, electrical motors etc.
3. Different colors are available based on RAL code; our standard
color is RAL 9006.
Features
1. High backholding torque to ensure safety of the solar
tracking system
2. Enveloping worm drive inside to improve multi-tooth contact to
ensure the high load
3. Self-locking function
Dual axis slewing drives are used in dual axis solar trackers,
heliostats, concentrated photovoltaics (CPV), and satellite
antenna.
By applying a dual axis slewing drives on a solar system, the
panels will always be oriented towards the sun, no matter the
season, time of the day or latitude of the regions. It can let the
project owner gain more electricity capacity up to 40%. And thus
more yield.
