SE21 Big Model Slewing Drive, High Tilting Torque Hydraulic Driven
For Construction Machinery
Construction Slewing Drive
With the wide application of construction machinery, more and more
main engine manufacturers choose rotary drives, which are quite
good in terms of load capacity and torque, thus ensuring the normal
operation of the equipment.
Advantages Driven By Hydraulic Motor
1. High transmission power
2. low speed and stability
3. Overload protection capability
4. Flexible transmission arrangement.

Applications
Self-propelled articulating arm climbing car
The articulated arm aerial work vehicle is a lifting device used
for aerial work. It can cross obstacles and perform aerial work.
When the platform is lifted to any position, it can be operated
while walking. It has a compact structure and flexible steering.
Narrow passages and crowded work areas.
Concrete pump truck
Concrete is the most commonly used building material. In order to
transport concrete quickly and effortlessly in a specific area, we
choose to use a concrete pump truck. By rotating the swivel arm of
the concrete pump truck, the nozzle of the concrete pump is aligned
with the desired position to complete the delivery of concrete. The
slewing bearing plays a vital role in this process. When developing
and designing the slewing bearing, special attention was paid to
ensuring its accuracy and robustness for conditions on construction
sites around the world, reliable high tipping moments to ensure
stable pump operation.
