Solar Slew Drive Description
VE5 solar slewing drive is usually used in PV solar tracking
system. It can also used in CSP, such as Fresnel, solar
tower/heliostat.
Fresnel concentrated solar power station, the working principle is
similar to trough type photothermal power generation, except that
the Fresnel structure condenser is used instead of the mirror. This
makes it relatively inexpensive, but the efficiency is
correspondingly reduced because such a system has only a few times
of concentrating, the quality of the heated water vapor is not
high, so that the annual power generation efficiency of the whole
system can only reach about 10%; but due to the simple structure of
the system and the direct use of heat-transfering medium to
generate steam, its construction and maintenance costs are also
relatively low.

Applications
The slewing drive device can bear comprehensive loads such as large
axial load, radial load and overturning moment at the same time,
and integrates various functions such as support, rotation,
transmission and fixation. Construction machinery is the initial
application of slewing bearings, and it is also widely used, such
as earth-moving machinery, excavators, disintegrators, stackers and
reclaimers, graders, road rollers, dynamic compactors, rock
drilling machinery, roadheaders, etc. Others are:
Concrete machinery includes: concrete pump truck, concrete mixing
and placing boom integrated machine, belt placing machine
Feeding machinery includes: disc feeder, sand mixer;
Lifting machinery includes: wheeled cranes, crawler cranes, portal
cranes, tower cranes, fork cranes, accompanying cranes, gantry
cranes;
Ground treatment machinery includes: impact reverse circulation
drilling rig, rotary drilling rig, impact rotary drilling rig,
rotary drilling rig, reverse circulation rotary drilling rig,
positive circulation rotary drilling rig, long spiral engineering
drilling rig, diving engineering drilling rig, static pile driver,
pile driving machine;
Engineering ships include: dredgers;
Special vehicles include: bridge inspection vehicles, fire trucks,
window cleaning machines, flat beam transport vehicles, aerial work
vehicles, and self-propelled aerial work platforms;
Light industrial machinery includes: beverage machinery, blow
molding machine, packaging machinery, filling machine, rotary
bottle unscrambler, injection molding machine;
Marine cranes include: floating cranes.
In addition to various construction machinery, the scope of
application of slewing drives has gradually expanded. At present,
equipment platforms such as port equipment, metallurgical
equipment, and drilling platforms have begun to use slewing drives
to replace original bearings on a large scale.
