Re-vamped
concrete pump
Liebherr has overhauled the design of its
47 M5 XXT truck-mounted concrete pump
M
anufacturer Liebherr
claims its new
47 M5 XXT truck-
mounted concrete pump has
been completely revised and now
offers additional advantages.
It said development and
optimisation of the mast was at
the forefront of this update, while
an array of design features has
been introduced to simplify the
replacement of wear parts for
more efficient servicing.
The new 47m, five-section
multi-fold distributor boom
is said to reduce vibrations to
an absolute minimum when
unfolding. To ensure a balanced
weight distribution, the concrete
pipeline is configured close to
the boom on both left and right
hand sides. Liebherr said minimal
pressure loss over the entire
length of the distributor boom
was guaranteed by the pipe
bend in the concrete pipeline,
featuring a radius of 275mm.
The 47 M5 XXT can be
equipped with two high-pressure
pump units featuring varying
performance outputs. Pump unit
140HL conveys up to 140m³/hour
concrete, whereas the 160HL
is capable of up to 160m³/hour
concrete.
A magnetic rotating flash
provides added safety and
visibility, while a pneumatic
pinch valve on the end hose is
said to prevent concrete spillage
when repositioning the boom.
Depending on customer
requirements, the 47 M5 XXT
can be arranged on a four-
axle chassis from selected
manufacturers, either MAN or
Mercedes for example.
A range of optional accessories
and equipment is also available,
including extra storage
compartments for example,
a second diesel tank or an
additional access point on the
left-hand side of the vehicle.

Smart sensing
Controls has launched the
Vicmatic-2 – a new generation
of cement setting testers,
representing a redesign on
previous models.
Controls said the new
device featured superior
functionality thanks to its
user-friendly interface and
software, and the fact that
it has a large test space and
can undertake in-water
testing. The unit can also be
expanded to create a network
of up to 32 independent
setting testers, all controlled
by a single PC through LAN
hubs.
The unit is said to be
suitable both for standard
tests and for research
purposes, allowing setting
and storage of user-defined
test profiles.
These include test start
delay, penetration points
position, manual or
automatic penetration rate,
free or driven falling mode,
automatic end-test detection,
and automatic determination
of initial and final setting
time at customisable depth
thresholds.
The challenge of stable slope signals
Sauer-Danfoss has introduced
new machine control technology
in the form of the CSS1000 dual
axis slope sensor, a device which
is said to cancel out transverse
machine motion to provide a
high-precision, fast-responding
and stable slope signal.
Designed for construction
equipment including pavers,
curb and gutter machines,
trenching machines and pile
drivers, the device features an
accelerometer and a gyroscope
on each axis for highly accurate
slope measurement.
Each axis has an operation
range of ±12.5o (±22% slope),
while an extended-range version
of the device is also under
development.
Sauer-Danfoss said the
CSS1000 could be integrated
into a control system developed
in PLUS+1 GUIDE (Graphical
User Integrated Development
Environment). Sensor tuning
parameters can be set via the
PLUS+1 GUIDE Service Tool.
Standard PLUS+1 housing is said
to offer a proven design and
multiple mounting options.
