For three years now, the M 32 truckmounted concrete pump belonging to the
ready-mix company BERDING-BETON
(Steinfeld) has been a firmly integrated
item in the resource planning of Vechta fire
brigade for the Osnabrück region. And only
just recently, the concrete boom was able
to demonstrate its valuable features in
fighting a major fire in Dinklage.

Although the 17 fire brigades from the
Vechta area and the neighbouring Artland
totalling 59 vehicles were quickly on the
scene of the fire – an approximately
4,000 m2 hall complex – the working area
of the two turntable ladders used was not
sufficient to cope with the situation alone.
The operation controllers therefore made a
quick decision to send for the additional
help of the Putzmeister BRF 32.16 H
belonging to the BERDING-BETON
company. Within a mere 15 minutes, the
truck-mounted concrete pump was converted into a highly flexible fire-fighting boom
as two firemen replaced a section of the
delivery line downstream of the pressure
pipe of the truck-mounted concrete pump
with a delivery line bend fitted with an
adaptor to the fire brigade’s coupling
system. A collective connection to accommodate the two B-water hoses was also
added. The end hose was removed from the
tip of the boom and replaced with a socalled S8 foam pipe using a coupling.
Concrete pump operator, Franz-Heinrich
Ritterhof, then directed the articulated
boom by radio remote control over the seat
of the fire. During the fire-fighting operations, foam was used to extinguish the
fire, instead of water. The foam was
provided from a tank fire truck which fed
up to 2,400 litres per minute to the delivery
line of the truck-mounted concrete pump.
As pump operator Ritterhof was controlling
the boom from ground level and the view
from above was restricted to the seat of the
fire, his mates from the fire brigade had to
improvise. From two higher observation
posts (a tree and a retractable ladder), they
actively and energetically helped to guide

the boom tip to where it was needed.
Christian Katzer, a fitter at BERDINGBETON and fire chief of the Steinfeld fire
brigade involved in the operations: “The
boom of a concrete pump is well suited for
fire-fighting operations. It is easily converted for the job without having the firemen
standing in the real danger areas!” By the
way – if a nozzle is connected to the boom
tip instead of the S8 foam pipe and only
fire-fighting water is sprayed, then the
reach with this combination of fire truck
and concrete pump boom is up to 70 m!
Unlike in the past, Putzmeister AG will not
be sending Christmas and New Year cards
of its own design this year to its business
partners but will be using UNICEF greetings cards instead. UNICEF has been
selling the cards for many years and using
the income to support numerous projects in
countries where it is most needed. For
example, the sale of 500 cards will finance
the equipment required in a complete
village hospital ward. Putzmeister hopes
the change will meet with the approval of
its customers and friends and would be
happy to learn that they liked the cards.

Extensive concreting for a complex bridge construction
14
The new, 820 m Yahagigawa Bridge has a three-lane carriageway in each direction of travel. Its impressive architecture is visible from afar.
15
Currently under construction in Japan is
the so-called Second Tomei Expressway,
urgently needed to deal with the high
volume of traffic between Tokio and
Nagoya. The new motorway will take
some of the pressure off the present Tomei
Expressway which connects the two cities.
16
principals JAPAN HIGHWAY PUBLIC
CORPORATION to two well-reputed construction companies KAJIMA KENSETSU
Co. Ltd. who is building the Western side
and ORIENTARU KENSETSU Co. Ltd.
who is responsible for the Eastern side.
Construction work commenced in October
2002 and work should be completed by the
end of 2004.
The new motorway project also involves
the construction of an 820 m long motorway bridge to span the Yahagigawa River
– a task which is worth several entries
in the Guinness Book of Records! The
most interesting aspect of the work is the
methods of placing and distributing
enormous quantities of mostly highstrength concrete into the piers of the
bridge and on to the formwork for the
road surface using stationary and mobile
PM concrete pump units.
The bridge across the Yahagigawa River is
a cable-stayed bridge resting on two
towers, which have a drop-shaped crosssection separating into two lattice-trussed
halves at a height of about 11 and 16 m
through which a six-lane road is spanned in
the centre of the carriageway. The two
structures meet in perfect harmony about
84 m above the ground, reaching a height
of around 121 and 126 m above the foundations. The impressive construction height
of the Yahagigawa bridge represents a
record-breaking project for Japan. The
contract for the works was awarded by the

Simultaneous concreting
of separate towers
A systematic diagram of the first phase of construction
showing the PM high-pressure pumps BSA 2110 HP-D
and BSF 2107 HP. Concrete placement in the towers
was made using two RV 10 rotary distributors.
Sub-contractors TYUOU KENSETSU Co.
Ltd. (formerly TAKASAGO KENSETSU
Co. Ltd.) were commissioned to concrete
individual sections of the impressive
motorway bridge. The company’s fleet
includes more than 20 Putzmeister concrete
pumps and is one of the largest concrete
pump service providers in Japan.
According to estimations made by the site
management no locally-manufactured concrete pump would have been able to carry
out the concrete installation on this construction site as almost all sections require
concrete to be pumped to a height of about
120 m – and that demands a very high concrete pressure. All in all, the amount of
concrete required for the towers and the
carriageway deck of the Yahagigawa
Bridge is estimated at about 24,000 m3.
Pump service providers CHUO KENSETSU
solved the problem by deploying two
Putzmeister concrete pumps type BSF
2107 HP designed specially for high concrete pressures and a stationary pump type
BSA 2110 HP-D. The BSF 2107 HP
(MOLI) is a truck-mounted concrete pump
17
18
without a boom which PM has designed to
deliver concrete through long pipelines
(i.e. for high pump pressures). The MOLI,
which stands for mobile line pump is frequently to be found in operation in countries in South-East Asia. Already in rod
side operation, the machines in this series
achieve concrete pressures of 150 bar and
pump flows of 68 m3/h, as does the “ordinary” stationary pump BSA 2110 HP-D
which, by the way, is designed for concrete
pressures up to 150 bar and outputs of up
to 110 m3/h in rod side operation.
CHUO KENSETSU have connected the
concrete pumps at each of the two towers
to two type RV 10 mechanical concrete
rotary distributors via high pressure-proof
ZX delivery lines. The concrete distributors
can be slewed horizontally over a working
radius of 10 m and in this phase of construction, one was installed to each of the
tower halves to enable the concrete to be
poured as rapidly as possible into the, in
parts, very complex formwork sections.
High-pressure pumps designed to
deal with 220 bar concrete pressure
The MOLI (mobile line pump) is a boom-less truckmounted concrete pump designed by Putzmeister
especially for the delivery of high-pressure concrete
through long delivery lines – the two operators are looking apparently well satisfied with its performance…
When pressure rose to 130 bar in about
80 m height, operational mode was switched to piston side in both the MOLIs and
the BSA 2110 HP-D. All of the pumps
were now able to deliver concrete up to a
pressure of 220 bar. This of course, for
physical reasons, reduced the output.
Nevertheless, around 170 m3 of concrete
was placed each day, tantamount to a daily
construction height of around 4.5 m. All
that was then needed to concrete the upper
As construction height increases, only one highpressure concrete pump and one concrete rotary
distributor are required for concreting the towers

using a power-driven high-pressure water
pump which had to be hoisted each time
by a crane up to the site of the concrete
placement.

High-strength concrete
for the carriageway
Concreting the carriageway deck was a totally different story for CHUO KENSETSU.
The substructure of the bridge consists of
pre-fabricated box girders on which a
carriageway deck rests as a relatively lightweight composite construction. The tensile
strength and flexural strength of the construction is provided by steel girders. The
reinforcement on top is cast in concrete.
With a width of 43.8 m for the main girder,
the Yahagigawa River Bridge sets yet another construction record for Japan as does
the distance of 235 m between the two
towers – an impressive performance for the
Japanese bridge builders.

In spite of occasional attacks, there is no
more stopping the re-building of
Afghanistan’s capital, Kabul. Following
our report in the PM POST No. 58 regarding the delivery of a M 36 to the
F.C.E.C. company and its building projects,
we would now like to present a brief
report on the construction of a new university complex.
MOLI high-pressure pumps
in combination with M 36 booms
To begin with, two Putzmeister type BSF
52.15 H heavy-duty boom pumps – one of
which was mounted on a semi-trailer –
took on the job of concreting the deck
formwork on the bridge. The five-arm
folding booms reached as high as the carriageway where they were positioned at a
right angle to concrete more than half of
the carriageway width in one operation.
As work progressed on the carriageway
sections, the process was changed: The two
M 52 heavy-duty booms at the foot of the
towers were replaced by two MOLI highpressure pumps which delivered concrete
via firmly installed pipelines first horizontally, then vertically to the M 36 truckmounted concrete pumps on the bridge
decks. Efficient and powerful pumps were
now required for casting the deck formwork because of the 60 N/mm3 concrete
compressive strength. The M 36 by the
way was used to distribute concrete and
not as a relay pump.

TARHE SAKHTE AFGHAN TOOS – an
Afghan-Iranian enterprise is currently constructing a modern university centre which
has been commissioned by Ayatollah
Mohseni. When work has been completed,
up to 4,000 students will be accommodated
on a campus of 36,000 m2. In addition to
50 classrooms, the area will boast a research
centre, a mosque, a library, a cafeteria, a
medical centre and residential accommodation for the students. In May 2004, by
the way, Afghanistan’s President Hamid
Karzai participated in laying the foundation
stone for the mosque – which will be one
of the largest in Kabul. In all, work is in
progress on ten buildings varying in size,
all of which are planned to be handed over
in March 2006 after a two-year construction period.
The construction site is providing a livelihood for more than 200 people. The concrete pour for the foundations and the construction of numerous floors was pushed to
some extent by AFGHAN TOOS by using
a new PM stationary pump type BSA 1005D
and an RV 10 rotary distributor. The most
important spares and wearing parts of the
BSA concrete pump, the couplings and the
rubber washers for the delivery line were
safely stored in a container. There is also a

for plastering jobs.
During the initial phases of constructing
the carcass, AFGHAN TOOS personnel
were making the concrete required themselves with the help of a 1 m positiveaction mixer which had to be filled by
hand. In this way, they produced about
4 – 5 m3/hour of concrete and daily performance averaged at around 45 m3. In the
meantime, AFGHAN TOOS is supplied
with concrete from a newly-built concrete
ready-mix works (capacity 30 m3/h) operated by the 2 RC company along the road to
Jalalabad. The distance to the AFGAHN
TOOS construction site is covered by the
truck mixer in about 20 to 30 minutes. That
means that there is now a considerably
greater volume of concrete available which
inevitably can be pumped and distributed
more quickly.

Compact
4-section boom
features numerous strong advantages
In the meantime, many pump service
companies have supplemented their
machine fleet with the compact and universally deployable Z-fold M 28-4. Our
brief report in issue 59 of the PM Post on
some of the features might have contributed to such a decision being made. The
following report describes the typical
advantages of this four-sectioned boom

ing operations can really begin, operator
Roland Bänfer and his mate, Heinrich Gräb
– who is on site today as a reserve man –
have calculated a 30 minute warm-up period to get their M 28-4 “Z-fold” ready for
operation. Then for this job for the Weber

version of the machine is also equipped
with the new fuel-saving EOC engine

The new BSF 28.14 H owned by the concrete pump service company HÄBEL
(Siegen) arrives punctually at nine in the
morning at the construction site in the
Netphen industrial park. Before the pump-

its long side immediately in front of the
entrance to the machine shop. The working

arm assembly is lifted, slewed sideways
and placed a little to the rear. Now the
boom can be unfolded – like a pocket rule
– and then driven to its end position in the
shop. It’s really quite amazing to watch
how quickly a “Z-fold” boom is ready for
work!
29
28
The M 28-4 belonging to pump service
providers HÄBEL also has a wide range of
accessories on board: 125 mm and 100 mm
delivery hoses and pipes for a total of
60 m, 65 mm hoses with a reach of up to
50 m, reducers, a considerable number of
couplings and rubber washers. Nothing is
left lying around loose on the flatbed –
everything has its place. Either in magazines, in a storage space, on holders or in
drawers.
In order to be able to reach into the furthermost corners of the floor formwork in the
shop, the 28 m extended boom must be
lengthened by approximately a further
25 m. The two HÄBEL experienced employees easily and quickly replace the end
hose on the boom tip with a reducer which
tapers the line diameter from 125 mm to
65 mm. In compliance with safety regulations, the boom tip is placed on the ground
and the reducer connected. In just a few
minutes, five 65 mm hoses have been connected – and pumping begins at 9.30, a.m..
The working range of the M 28 Z-fold boom can be used without too great a loss in lateral reach
“With my M 28 pump, not only can I pump
large quantities of concrete for floor slabs
or floors, but I also frequently work on
smaller construction sites where pumps
with larger booms cause problems when
setting up the machine. Not to mention
renovation sites which of course, are not
always at the roadside. That means in about
every third job, it is necessary to extend the
boom delivery line by attaching additional
hoses”, estimates pump operator Bänfer.
“Here in the Siegerland, we are confronted
by conditions that are either narrow, steep
or confined. But I am always able to find a
space for our M 28; I can even set it up
between the site trailer and the Dixi site
toilets!” When he mentions needing less
space, he is referring to the front diagonal
support (support width 6.2 m) and the
almost vertical support legs at the rear
(where the support width is just 2.6 m).
What he also likes is the manoeuvrability
of the four-sectioned boom which is made
possible by its short wheel base.
31
The special version of the BSF 28.14 H
belonging to HÄBEL is also equipped with
the new fuel-saving EOC engine speed
control. The EOC – or Ergonic Output
Control – is just one of the extras provided
by PM in the “Power Kit”. Putzmeister has
developed the Ergonic Output Control
(EOC) module as a control system for

makes it easier for the concreting team,
there’s less concrete residue and it’s easier
to clean up afterwards.” According to his
observations, there are practically no natural deposits of 16 grain size in the Siegerland
– in contrast, for example, to the neighbouring Ruhr District. “The 16-grain chippings
we send through the narrow lines should
contain ample fine particles, otherwise we
will quickly have too much wear and tear.”
In the meantime, most of the mix companies in his catchment area have changed
over to using fine-grain concrete with 0/8
chippings for renovation work. “Before I
begin to place any concrete, I send a few
buckets of grout through the line and then
I start the job!” The retro-fitted high-pressure water pump means that cleaning operations are dealt with quickly and thoroughly, even in the big delivery lines.
Radio remote control allows pump operator Roland
Bänfer to remain close to the placement site
65 mm hoses are easy to handle
further optimising fuel-saving concrete
pump operations. As soon as the operator
has set a desired output via radio remote
control, the EOC fuel management automatically regulates the required minimum
r.p.m.. Using EOC not only reduces diesel
consumption in concrete pumps but also
noise level and, last but not least, wear and
tear in the machines. When required, this
value can be manually “overridden” to set a
higher or lower r.p.m. However, fuel is also
saved when in “normal operation” mode.

How PMUK performs is dependant on the
entire team, and those behind the scenes
are every bit as important in delivering
quality to the customers. This culture has
been reinforced in the systems and
structure already developed to achieve

Strengths built on differences
It can come as no surprise that, as in
other aspects of life, the UK market for
Putzmeister products does not always
follow the European norm. As a consequence it has been necessary to innovate,
look for alternative markets and new
applications.
The beginnings were certainly humble, just

the first pumps were assembled, the other

Chesterfield, where the current premises
were built in 1981.
Over a period of six years more buildings
were rented to accommodate the growing
demand. This may not have been a glamorous start, but it established the culture of
financial strength and self-sufficiency that
has become a hallmark of PMUK, and provided the resources to acquire the site in
Whilst the buildings are important PMUK

products, and about people with a commitment to providing the best for their customers, not always succeeding, but willing
to learn, and come back stronger for the
experience. PMUK can take pride in an

years, but without losing any of the enthusiasm. Mick Ferguson the Service Manager
has been with Putzmeister from the beginning, and still finds new challenges, still
gets excited by talking a customer through
a problem, still looks for ways to improve
the service his team provides and how it
isdelivered. PMUK invest in training and
forward planning to ensure this fund of
knowledge and practical experience of the
machines, applications and operations is
secured for the future.
This has helped to make PMUK more
responsive to market requirements, and has
resulted in a number of successes over the
years. The City Pump concept of a small
mobile concrete pump was conceived in
1986, and in 1987 the first units were
assembled in Chesterfield with 16 m boom
and 1005 pump mounted on a 13 t chassis.
Initially this model attracted a number of
new operators into the pumping market,
and has evolved over the years until small
concrete pumps now feature in most UK

Primera trailer mounted concrete pump is
an example of responding to specific
customer needs, and through co-operation
developing a new model. This simple,
robust unit was introduced in 1998, and has
gone on to form the backbone of
Putzmeister trailer pump sales in the UK.
As with all Putzmeister products this
model is subject to continuous development to take advantage of new technology
and incorporate new customer led features.
The hydraulic Mixokret – M3250HD was
developed and assembled in the UK and
introduced in 1997 when sales into this
sector were somewhat erratic. This new
model with hydraulic drive gained immediate market acceptance, and continued to
perform strongly through to its replacement
by the M760DH in 2001.

identify new opportunities to support
existing customers, with the 350 mg Plus,

The concrete being poured is a C30/37
with a 16 – 22 cm slump and, as a rule, a
water/cement ratio of about 0.45. Aggregates consist of broken materials and are
up to 50 mm in size. In spite of the addition of a plasticizer and an apparently softsticky consistency (F4), this concrete is not
easily pumped. For example, the manometer shows an increase in hydraulic
pressure of 260 – 280 bar each time the
S-tube is connected. The reason is special
additives which are put into the concrete
batches in the mix unit.

Warsaw pump service concreting
the “Golden Terraces”
building complex
Solid building components
made of self-compacting
concrete
In the city of Warsaw next to the Centralna
(main railway station) and right opposite
the 231 m high-rise Palace of Culture and
Science, ING REAL ESTATE is investing
around e 250 million in the construction
of a multi-functional building complex
which goes by the name of “Zlote Tarasy“
which means “Golden Terraces“. Many of
the supporting components are made of
high-strength, self-compacting concrete –
the wall thickness in some of them is up to
150 cm. Putzmeister pumps and booms
have been commissioned to deliver and
place the considerable quantities of concrete required for the project.
44
On completion, the underground car park
will accommodate 1,800 vehicles on four
levels. The three storeys above the car park
will house numerous shops, restaurants,
service providers and a state-of-the-art
multiplex cinema. Additionally planned is
a hotel with 450 beds. The upper storeys
will be rented out as office premises and
residential apartments.
Sub-contractors bear a
great responsibility
SKANSKA Sp. z.o.o. as the main contractor is responsible for the mammoth
project. As the “Golden Terraces“ are to be
multi-functional, the carcass is being constructed as four separate zones differing in
their architecture. Whilst SKANSKA is
building all of the foundations and sectors
1 and 2 using its own personnel and fleet
of machines, sub-contractors
HYDROBUDOWER 6 (HB6) have been
commissioned with the construction of
zones 3 and 4. Both SKANSKA and HB6
are relying on the know-how and technical
equipment of specialists in providing concrete pumps – i.e. on BOSTA Beton and
WARBUD S.A.
Both of these Warsaw pump service companies are deploying several of their PM
machines in the construction of the
“Golden Terraces“. For example, for work
on the 1.5 – 2.5 meter thick floor slab and
for placing concrete on floors in zones 1
and 2 at varying heights, BOSTA-Beton
used in each case two M 28s and M 42s.
Even throughout the night, concreting

The WARBUD company also commenced
work initially using their mobile Putzmeister
truck-mounted concrete pumps M 36 and
M 42. As the height of the building increased and delivery distances of more than
100 m were required, WARBUD switched
over to just stationary concrete pumps and
placement operations. Since January 2004,
a Putzmeister BSA 1409 D and a mechanically slewable concrete boom in sector 3
have formed a concreting unit and in zone
4, a BSA 2110 HP-D has been working
together as a team with a stationary concrete boom MX 32 T.

According to enquiries carried out by the
Frankfurter Allgemeine Zeitung, Poland’s
building industry is on a definite road to
recovery; this can be attributed to the
improved economic situation and resulting investments. In addition to privately
financed construction projects, the future
will see more and more funding from the
EU funds to benefit especially civil
engineering and road construction as well
as special environmental construction
projects. The increasing number of tenders for major projects has contributed to
an improved climate in the building industry: alone in the first quarter of 2004,
there was an increase of 20 % compared
with the figures for the same period in
the previous year. (FAZ, 7 June 2004)

Andrzej Zdziesznski is the operator responsible for the six-year old Putzmeister BSA

trial batch through the line. “And then it
runs on its own!” As output pressure is
never high (e.g. only 150 bar hydraulic
pressure at 40 m pump height), the rod side
of machine is pressured, i.e. operates

building and 56,000 m3 for the foundation),
about 4,800 m3 is SCC material. The

Self-compacting concrete is used for example in sections where a vibrator cannot

“Golden Terraces“ planning phase,
ALLTECH specialists were able therefore
to give the main contractor SKANSKA
practical tips regarding optimum concrete
pours for this complex construction site.
ALLTECH, registered in Warsaw and
Sopot (near Gdansk) has been representing
Putzmeister AG in Poland since 1992. The
15 employees at ALLTECH – four of them
exclusively responsible for service and

Sika -PM wet spraying systems
back up tunnel advance work along
the Mediterranean Highway
Work is currently on-going on a further
section of the Mediterranean Highway
in the south of Spain, where three
Sika®-PM500 P type concrete shotcrete
spraying devices are being employed in
backing up advance work in each of the
three twin-bore tunnels (total length
5.04 km) along the total stretch of 9 km.
The section under construction between
La Herradura and Taramay (Almuñécar
area) is part of the “Autovía del
Mediterráneo” which will link up the cities
of Cádiz and Gibraltar in the South of the
Iberian Pensinsula and Barcelona in the
North East.
The 9.1 km long section which is being
built by U.T.E. LA HERRADURA, a
joint venture comprising the construction
companies PLODER S.A., AZVI S.A. and
OBRAS SUBTERRÁNEAS S.A. runs over
a distance of 1.8 km joint, 4-lane carriageway and then over a distance of 7.3 km in
each direction of traffic as a separate route
through three twin-bore tunnels (in total
2.52 km long) and four bridges (in total
2.17 km long). The project commissioners,
the Ministerio de Fomento, had initially
calculated construction costs totalling
A 180 million for the complex track
routing; which meant the highest motorway costs in the whole of Europe – A 20
million for each kilometre. Construction
costs are now put at A 157 million. Work
commenced in March 2003 and completion
is expected for September 2006.
Whereas the bridges consist of two parallel
girders each 350 m, 2 x 580 m and 630 m
long, the tunnels in each direction of traffic

A newcomer to the Putzmeister AG product
range is a pneumatic pinch valve for the
end hose. The idea itself i.e. to „squash the
ends of the hose together“ in order to avoid
concrete leakage is known. This new
squeeze valve is made completely of rubber and is simply pushed over the concrete
end hose. It is opened and closed pneumatically via radio remote control automatically. With only a few seconds delay, the
valve closes or opens the end hose as soon
as the operator has given the command
“Pump ON” or “Pump OFF” via radio
remote control. The pinch valve can be
completely switched off at any time via a
toggle switch on the control cabinet.
The Sika®-PM500 P have an extensive
working reach and are therefore well suited
for shotcreting jobs on high embankments
as well as in underground chambers and
tunnels. Dimensions range from 4.5 m to
17.5 m. The Putzmeister twin-piston pump
installed lengthwise at the rear of the truck
has over 1000 mm lift and 180 mm
delivery cylinder diameter, as does the
stationary pump BSA 1005. With a capacity of 30 m3/h and just 19 strokes/minute,
this core pump is simply ideal for vibration-free shotcreting jobs. The horizontal
automatic on the spraying arm has proven
very helpful in shotcreting work in the six
LA HERRADURA tunnel bores.
This device enables the cradle to be extended by 3 m and held in a horizontal
position. In conjunction with the highly
manoeuvrable head of the spraying nozzle
this results in an extraordinarily even spray
pattern with little rebound.
The pinch valve can be completely switched off at any
time via a toggle switch on the control cabinet
58
56
All of the Sika®-PM500 used at the LA
HERRADURA site are standardly equipped with a liquid metering device (Sika®Aliva-403.5) and one or two tanks for concrete accelerating agent (capacity in each
case 1000 l). As the site already provided
compressed air lines in the tunnels, the
spraying devices were not supplied with
their own compressors. A total volume of
75,000 m3 of shotcrete was placed in the
six tunnels. The pumping of concrete for
the tunnels – approximately 80,000 m3 in
strength class C40/50, 180,000 m3 highstrength concrete C 60/75 and 100,000 m3
in strength class C25/30 – was placed using
stationary concrete pumps, which had been
previously used for building the bridge
piers. Here, too, only Putzmeister machines
were used.

are designed as single structures. All of the
six bores (2 x 2170 m, 2 x 278 m and
2 x 220 m) have a full section of approximately 110 m3 and advance work is progressing at 6 to 10 m per day – depending
on whether supporting arches type THN 21
and THN 29 need to be installed or not.
The three mobile shotcrete Sika®-PM500 P
spraying devices have been operating on
individual construction site sections since
September. They were first used to secure
the slope area around the portals and in the
meantime are needed to quickly secure
tunnel excavation work according to the
new Austrian tunnel construction process.
As the machines are equipped with fourwheel drive and four-wheel steering they
are easily manoeuvrable even in difficult
terrain.

As no metal collars or metal rollers have
been used, it is, on the one hand, irrelevant
at what height the rubber collar is attached
to the hose. On the other hand, the new
switch-off valve is so light, that when fitted
to the standard boom end hose, stability is
not impacted. That means that the end hose
need not be shortened by one meter, as is
usually the case.

France – the
land of
the rotor fans
For years now, the demand for
Putzmeister rotor PUMI s among our
®
neighbours in France has been considerably higher than that for PUMI®s with a
piston pump. The rotor system – in
France it is also known as “ROMIX” – is
so well-known and successful that some
customers would like to install the rotor
onto a “normal” truck-mounted concrete
pump with boom. Putzmeister is only too
pleased to put this request into practice.
We came across one of these truck-mounted concrete pumps from the BQF series
on a typical construction site south of
is part of the large fleet of vehicles belonging to BETON DE FRANCE, a pump service company operating all over France.
Operator Alain Meroy has been working on
the rotor pump for three years delivering a
whole range of different materials. In the
evening, he does not go back to his depot,
but takes his ROMIX home with him!
“That’s better for me because I save myself
the trip to the depot and in the morning, I
can drive straight to the construction site.
All the many traffic jams in and out of
Paris mean you need to calculate extra time
to get to the site punctually”, he explained.
As the operator and the machine are practically left to their own devices, the BQF is
equipped with all the accessories needed
for “an emergency”.

Waiting for concrete
At 7.15 a.m., the rotor pump arrives at the
construction site. In half an hour, the pump
is ready for operation. The boom has been
placed over the wall in position and the
100 mm pipe and delivery line have been
connected with a reducer. It’s late – and
around 9.00 a.m. the first of three truck
mixers turns up. So there is enough time
for a chat at the vehicle and then for an
espresso with the PM visitor in the café
next door. Along the way, we are told that
Alain Meroy pumps using a 4,000 m3 rotor
hose, a wearing part, which is replaced
about 3 or 4 times a year. “No – we don’t
just turn the hose around in order to lengthen its service life”, states operator Meroy
clearly, and he goes on to tell us all about
the different materials his rotor delivers,
with never a word of complaint! “I pump
everything the pinch valve can cope with –
whatever happens to come along: lean concrete, lean mortar, steel fibre reinforced
concrete, light-weight concrete, that means
materials which would not be so suitable
for a piston pump. So, I am never at a loss
for work!“
The hose is placed around the side of the building
The 24 m boom serves as a “pipe bridge” taking the garden wall in its stride
66
Even a pump hose
has only one life
It doesn’t happen too often but
occasionally it has been observed that
after the rotor hose has dealt with a
certain quantity it is not replaced, but
simply turned around. This attempt
assumes saving costs and extending
the service life of the wearing part.
Jörg Herrmann, head of the Central
Service Station at PM AG in Aichtal
doesn’t think much of such reputedly
economizing measures: “It takes more
time to turn the pump hose around
than it does to replace it with a new
one because the hose spout must be
removed from the ends and then pushed on again after the hose has been
turned. And afterwards, the operator
still has a worn rotor hose, in which
the fabric lining has been subjected to
great stress. The risk of the hose bursting is therefore very high, And all
that just to save A 840 for a new rotor
hose? There is nothing to be gained
from it, you only lose out!”
No need to dispose of concrete residues –
saving detours and time
This job also reveals other strengths of the
rotor system. The whole of the concrete
can be pumped forward into the formwork
- an important feature - as otherwise there
would be no way of cleaning the pump
system and the delivery line on the construction site. This speciality is also an
important reason that the M 24 rotor concrete pump earns its keep on average at two
sites each day in spite of frequent traffic
congestions. It would have cost operator
Meroy a lot of time in those traffic conditions to drive off to the next disposal site.

OEVERMANN installed MEVA formwork

platform which was supported in the elevator shaft. Half of the ceiling area and the
walls of the building’s core were to be reinforced and simultaneously concreted wet

climbed upwards together with the MX

The wall runs from the Cloister Mill about
200 m upstream, separating the Neckar
from its old natural river bed. The surface
of the sloping shoulder of the weir had
been increasingly washed away over the
years. The work immediately next to and in
the Neckar had been planned to take place
at low water.
After placing an improved sub-base, a
BSF 42.16. H belonging to BNA Betonpumpendienst (Reutlingen) delivered about
100 m3 of C 20/25 concrete to the masonry.

only sure instincts when setting up the
machine but also OSS – one-sided supports

could also be reached by the truck mixers.
Achim Baierl is a fully qualified, trained
and tested concrete pump operator and was
therefore very much aware of the risks of
setting up the machine so close to the river
banks and of the need to comply with
safety regulations.

Concrete was delivered from the BSA
stationary pump as far as the boom through
a high-pressure pump line, totalling 120 m
in length. It comprised for the most part
ZX pipes which were supplemented on two
short sections by high-pressure SK lines
(130 bar operational pressure). At the interface between riser pipe and stationary
boom pipework, a delivery hose – likewise
able to withstand 130 bar – ensures flexible
transition. Concrete was installed up to a
maximum of 30 m3/h.
During the whole period of installation, the
piston side of the BSA 1408 E was under
pressure. At a height of 91 m (max. height
of the facade), hydraulic pressure was
about 220 bar which equals concrete
pressure of 67 bar (i = 3.3). To facilitate
cleaning, a gate valve was installed into
the delivery line about 12 m downstream
of the BSA stationary pump.
