What’s New - Plant & Equipment
Previously available as an option, Cat Grade Control
Depth and Slope, a Cat Connect Grade technology, is
now standard on Cat 323E L (N) hydraulic excavators
sold in Europe with the 2.9 meter stick and standard
reach boom.
This 2D system is integrated into the machine’s
standard monitor and indicates real-time position-
ing and cut-and-fill information. This assists opera-
tors with efficiently and accurately achieving con-
sistent depth and slope grades without guesswork.
This results in faster times to complete work with
fewer passes, increased fuel savings and minimal
expense marking out and checking.
Significant productivity increases of up to 35%
and documented fuel savings of up to 6 percent
have been achieved with the system.
Cat Grade Control is integrated into the machine
at the factory with sensors and components built
into the machine. This reduces the risk of theft or
damage during operation, protects the customer’s
investment, and increases machine resale value.
Integrated joystick buttons allow operators to
adjust grade settings without removing hands from
the controls, while the display provides a simple en-
vironment for the operator to interact with the sys-
tem.
Audible warning indicators can be activated to alert
the operator if the bucket cutting edge or tip is
above, on, or
below grade.
Addition-
ally, height
and depth
limit alerts
can be set to
warn the op-
erator if the
linkage or
bucket ap-
proaches a
predef ined
elevation or
depth, such
as when
digging near water lines, or in areas with low ceil-
ings.
The system is easy to use, requiring only that
the operator references a vertical starting point
to “benchmark” the system – either by touching a
known point, such as a hub or stake, or by referenc-
ing a laser beam from a transmitter located on the
job site.
The operator simply enters the desired depth
and slope into the display and is ready to begin dig-
ging to grade.

Vibratory plates with
only good vibrations
The latest innovation for reversible vibratory plates
from Wacker Neuson in the weight class from 300
to 800 kilograms (or 40 to 100 kN of compaction
performance) reduces vibration values to less than
1.5 m/s² for hand-arm vibrations. According to the
Directive 2002/44/EC, the operator may, therefore
work without a time limitation with this
equipment.
With a new damping concept, Wacker
Neuson has managed to reduce the hand-arm
vibrations to a val-
ue that allows
the operator to
work without
a time limita-
tion and at the
same time pro-
vides for more
comfort and safety.
The diesel-powered vibratory plates DPU 4545,
DPU 5545 and DPU 6555 achieve values of less than
1.5 m/s². The DPU 4045 lies at just 0.9 m/s².
The advantages for customers are obvious: they
have powerful vibratory plates, save time and mon-
ey due to the reduced documentation and training
effort and operators benefit from the low hand-arm
vibrations, which ensure more comfortable and
gentle work.
With the introduction of the new center pole,
Wacker Neuson is now offering the entire product
series of reversible vibratory plates - from 140 to
800 kilograms with an operating time of at least
one working day. The vibration values are below
the trigger value of 2.5 m/s²; for the 30 kN equip-
ment vibration values are below the exposure limit
of 5 m/s² (permissible working time: 8 hours per
day).
