2MDs Message
Welcome back and wish you all a very happy and prosperous New
Year 2013. May God's grace prevail for all good things to happen
around.
After a string of festivals in the last quarter of 2012, it was
a series of customer interaction activities for Schwing Stetter
India in the first
quarter of 2013. Schwing Stetter India participated and
sponsored many events in the first quarter of 2013, viz., being the
principal
sponsors of IFAWPCA the National Contractors' Association's
convention in Kochi and being an active participant in the Cosmo
Expo
2013 Fair at Raipur and the FIB Seminar at Larsen & Toubro's
ECC Division, Chennai in the month of January, 2013. Schwing
Stetter India
also participated in Bauma Conexpo's BC India Fair held at
Mumbai and in the National Seminar on 'Constructions at Great
Height
in High Rise Buildings' conducted by the Institution of
Engineers, Mumbai during February 2013.

Our equipment also created a record of sorts, which are detailed
in this issue. Noteworthy of these are 1840 m of concrete produced
by
Lafarge in 55 hours and 83 m vertical pumping by a small Schwing
pump SP1200 in Pune. I am sure with more and more co-operation
and
understanding among our technicians and the customers, we are
poised to set many more records. Schwing Stetter India since
inception,
strongly believed in education and training of its employees,
technicians, customers' operators & technicians, besides
conducting specialised seminars by inviting specialists from its
parent company in Germany on special concreting
technology. In continuing with this education / training
programs, we have taken up the task of providing
leadership and managerial training program for our middle and
senior level executives at IIM Lucknow. About 20
employees would undergo training during this initiative. Such
initiatives are with a view to prepare ourselves for
the future challenges, as we strongly believe that India is a
growing market.
The Union Budget was announced and even though there are not
many surprises, it appeared that the government
and the finance ministry are determined to push infrastructure
projects and thus, economic development. We hope
to see many fresh contracts being awarded which will improve the
sentiments of the stake holders.
I wish you all a successful and bright future.
GIFT City Project
Projects in Progress
All the best,
A prestigious commercial project Gujarat International Finance
Tech
City (GIFT) is being constructed at Gandhi Nagar, Gujarat. It is
the
tallest commercial tower in Gujarat, standing 31 storey high.
With
built of 130 Mts, L&T ECC and IL&FS are using Schwing
Stetter
machineries to achieve this target. L&T approached SSI to
plan the
concreting method and high-rise pumping for achieving the
maximum output in concrete placement. These two towers at
GIFT
city project are a mixture of both Commercial &
Residential
complexes.
Concrete Pour
L&T is using our separate placing
boom SPB35 to achieve fast
progress and maximum output.
Schwing Stetter equipment has
produced around 42300 m of
concrete to complete the full
structure. SP 1800 HDRL with SPB
35X Concrete Pump produced
45m/Hr. An average of 3300 m
concrete is being produced every
month for the past 13 months
comprising of various grades of concrete. Concreting at this
high-rise
project was done smoothly at 202.5 meters vertical pipe line and
total
pipeline length was 262.5 meters with the joint efforts of
Schwing
Stetter service team and L&T team. Schwing Stetter with
L&T team
carried out water cleaning system to overcome the wastage of
concrete in pipelines. With the help of this system an average
of 205 3
m of concrete was saved in the last three months of the
project.
Record Break3
A SP 1800 Concrete pump ran continuously to pump 1000 m of
concrete for each floor up to a height of 130 meter without any
major 3
problem on the pump performance. To pour this 1000 m
concrete,
the pump ran continuously for 48 to 52 Hours. The P&M team
from
L&T was extremely happy with the performance of Schwing

8Project Abroad
Going the Distance Niagara Tunnel Project
An entire fleet of eleven Schwing stationary pumps with
various
configurations along with extensive fleet of Schwing boom
pumps,
under the guidance of Pumpcrete, conveniently located in
Niagara
Falls, are working around the clock on Niagara tunnel project.
The
project will divert 35 percent of the Niagara River at night and
a new
massive diversion tunnel will add additional hydroelectric power
to an
existing generating station with enough electricity for 160,000
more
homes.
Pumpcrete has an extensive tunnel lining resume. The
difference
with this tunnel is its immense diameter, explains Dave
Moriarity,
Pumpcrete manager. This one you could erect a five story
building
inside the tunnel.
Shotcreting was part of the excavation contract to stabilize the
bore
hole perimeter but additional shotcrete was required to fill
voids in
loose soil conditions. The company utilised three Schwing SP 500
split
units to apply the shotcrete to a thickness of 13 cm through
hand-
held hoses and shotcrete robots attached to the TBM (Tunnel
Boring
Machine). The wet shotcrete was applied over reinforcing
mats
anchored into the tunnel walls.
A shotcrete arm provided extra reach to fill voids that occurred
when
soil conditions were not ideal. A Schwing SP 1000 was used to
feed
the arm and to provide additional velocity to the shotcrete.
Strabag
subcontracted batch plant operations and trucks supplied the
pre-
mixed shotcrete to the electrically powered pumps. More than
120,000 cubic meter of shotcrete was applied
over the five years of tunneling.
Following behind the shotcreting operation is the form and pour
for
the tunnel invert the bottom one-third of the tunnel lining.
Pumpcrete utilised two Schwing SP 2000 stationary pumps that
are
fed by agitator trailers hauled in by trucks. The tunnel lining
concrete
is a pumpable mix according to Moriarity, explaining that the
mix
designs are proprietary.
Output to the two form systems that leapfrogged their way
through 3
the bore hole was between 40 and 50 m per hour. The form
systems
travel about 50 meters in front of the electric powered trailer
pumps. 3
Each pour advances the invert 12.5 meters and consumes 120 m
of
concrete. Water is used to clean out the pipeline systems with
a
diversion valve on the pump's discharge that sends wash water
and
residual concrete into trailers to be disposed off outside the
tunnel.
The loads must be spread evenly throughout the tunnel's
circumference. Therefore, all voids need to be grouted in order
to
keep the thickness of the inner lining within specified
tolerances of 30
centimeters. Because of the internal water pressure of up to 15
bar
(2,175 psi), the lining must be fitted accurately into the
surrounding
rock.
Pumpcretes close location to the project allows them to draw
on
their extensive fleet of Schwing boom pumps
Waterproofing Manager Stefan Mackinger explains why
elaborate
waterproofing is mandatory for the success of this tunnel,
The
tunnel designer specified a single-layer waterproofing membrane
for
non-swelling rock and a double-layer membrane for the
Queenston
Formation, an area that contains argillite, which swells in
contact with
water and would ruin the concrete lining.
To complete the remaining two-thirds of the concrete tunnel,
Pumpcrete chose a Schwing electric SP 5000 split unit that was
3
positioned under an 8 m Maxon Maxcrete agitating surge hopper
to
travel into the bore hole. A Schwing SP 8000 outside the tunnel
fed
the surge hopper.
Because of traffic through the tunnel, the SP 8000 pumped
through a
five-inch line for as long as possible.
We were amazed that Schwing was able to push the mix as far as
1.7
kilometers, explained Pumpcrete owner, Ken Williams, Jr.,
That's
more than a mile and probably some sort of record. The crews
eventually resorted to feeding the pump with trucks and
trailers.
3
By the end of the project more than 300,000 m will be pumped
with
the Schwing units. Pumpcrete's contribution to the project
is
immeasurable. A partner in concrete placement means use of
good
equipment, experience and reliable operators and parts
support
especially in tunneling. Pumpcrete has supplied all of these
components. according to Bernhard Mitis, Strabag's manager for
the
concrete portion of the project.
Schwing SP 5000 is positioned under a remixer
that receives concrete from agitator trailers.
Arch form for the tunnel lining is fed by a Schwing SP 5000-
positioned
up to 50 meters behind the form system.

Belt Conveyor(Installation, Operation & Maintenance)
INSTALLATION
OPERATION
1. Please ensure that the installation is done with
necessary
precautions. Measure the belt without creasing, folding or
straining.
2. Care should be taken while splicing or vulcanising to ensure
that
the joint is made correctly & no horizontal bends are
developed
in the belt while making joint out of square.
3. Belt should be clean and free from oil and grease.
4. Belt and Conveyor Supports should be in proper alignment.
5. Power transmission machinery should be checked for proper
alignment on assembly.
1. Before starting Conveyor, ensure that the Conveyor structure
is
firm enough to prevent vibration.
2. Before starting the Conveyor, care to be taken to see that
there is
no coal lumps, chips and wood or pieces of iron etc., on the
carrying and return belt.
3. After confirming no load operation, feed material on the
Conveyor Belt, uniformly and carefully.
4. Quantity of material feed should be controlled. If the
material is
fed in excess, the motor of the Conveyor will get overloaded.
In
addition, the material on the belt is bound to spill.
5. At the loading point, skirt boards are used to centralize
material,
falling off the belt. The skirts should have proper contact with
the
belt.
6. Proper belt tension should be maintained by the take-up,
a) To ensure that minimum tension in the belt is sufficient
to
prevent undue sag between idlers. b) To transmit load.
7. When the Conveyor has to be stopped, please ensure that
there
is no material left on the belt.
Maintenance
The general good maintenance practice is as follows:
1. Check clearances periodically.
2. Emphasize visibility in loading and unloading sections and
in
control locations.
3. Confine the operation of conveyors to authorised
employees
only.
4. Confine repair functions to trained maintenance employees
only.
5. Repair damaged belts immediately.
6. Do not permit riding or stepping on conveyor.
7. Instruct employees using conveyors on the methods of

needs a few years ago, are obsolete today. Only few companies
with
proactive powerful leadership monitored the environmental
change
and succeeded even during the difficult times and Schwing
Stetter
India is one of few such market leaders.
We are one among the few companies who have extended our
various value added customer services across the country
directly to
stay close to our customer to support their product. Keeping
the
growing trend of Schwing Stetter equipment and non availability
of
skilled man power in the industry, Schwing Stetter India has
incepted
its state of the art service centers in different states and
many are to
follow.
Why service center
Services offered
As Schwing Stetter India understands, effective outsourcing is
one of
the most proven and reliable solution to meet the requirement of
the
market without increasing the working capital. When the OEM
offers
the solution in the form of service center it is obvious that
customers
would grab the opportunity with both the hands.
Periodic maintenance
Rectification of defects from Minor to Major
Rewiring of Electrical system and Rebuilding of Hydraulics
Repainting of equipment
Mounting of Transit Mixer & Boom Placer
Conversion of flat gate valve to rock valve and vice versa
Conversion of diesel driven to electric driven and vice
versa
Sale of refurbished equipment
Repair of sub assemblies like Hydraulic pump, motor, gearbox
etc.,
Helps to handle the insurance claims with timely and precise
estimates during / after an accident.
Understanding the need
Retrofitment
Standby
Specialised Repairs
Conversion: Flat gate valve technology was introduced when the
site
requirements for concrete mix was predominant. These pumps
were
not able to meet the concrete requirements in high rise
constructions.
To overcome these issues, Schwing Stetter India has come up with
its
unique option of converting the flat gate valve into rock valve,
for its
customer to meet the requirements. The conversion from flat gate
to
rock valve came as second lease of life for those who opted to
convert
their pumps. We have received accolades from many benefitted
customer.
Many customers are benefited
from the retro fitment solutions
provided by Schwing Stetter
India's service center. This made
most of the customer to prefer
Schwing Stetter equipment.
As the projects are critically time bound, there is no margin
for error
for the pump to be under break down even for short duration. On
the
other hand if new pump is kept standby, cost rockets sky
high.
Schwing Stetter India plays a major role by providing limited
warranty
for refurbished concrete pump to help the customer. These
pumps
are also exported to the countries like Srilanka and
Singapore.
Many specialised machines prior to execution at major projects
get
serviced at Schwing Stetter India service center. To mention
few,
BP 4000, BP 3500 for Parbati dam project executed by Gammon
India, KVM 42 boom pumps for Petron.
Customer Testimony
We express our sincere thanks for the
co-operation SSI have extended during
the execution of conversion of our

Star Batcher

Tech
Most induction motors are started directly on line, but when
very
large motors are started that way, they cause a disturbance of
voltage
on the supply lines due to large starting current surges. To
limit the
starting current surge, large induction motors are started at
reduced
voltage and then have full supply voltage reconnected when they
run
up to near rotated speed. Two methods are used for reduction
of
starting voltage which is star delta starting and auto
transformer
starting.
This is the reduced voltage starting method. Voltage reduction
during
star-delta starting is achieved by physically reconfiguring the
motor
windings as illustrated in the figure below. During starting the
motor
windings are connected in star configuration and this reduces
the
voltage across each winding 3. This also reduces the torque by
a
factor of three. After a period of time the winding is
reconfigured as
delta and the motor runs normally.
Working Principle of Star-Delta Starter:
Star-Delta Starter
Star-Delta starters are probably the most common reduced
voltage
starters. They are used in an attempt to reduce the start
current
applied to the motor during start as a means of reducing the
disturbances and interference on the electrical supply.
Traditionally in many supply regions, there has been a
requirement to
fit a reduced voltage starter on all motors greater than 5HP
(4KW).
The Star-Delta (or Wye-Delta) starter is one of the lowest
cost
electromechanical reduced voltage starters that can be
applied.
Application of Star-Delta Starter:
Advantages of Star-Delta starter:
In SCHWING Stetter Batching Plants we use Star-Delta Starter
in
most of the Pan Mixers and Twin Shaft Mixers.
The Star-Delta method is usually only applied to low to
medium
voltage and light starting torque motors.
Features of star-delta starting
For low- to high-power three-phase motors.
Reduced starting current
Six connection cables
Reduced starting torque
Current peak on changeover from star to delta
Mechanical load on changeover from star to delta
The operation of the star-delta method is simple and rugged. It
is
relatively cheap compared to other reduced voltage methods.
Good Torque/Current Performance.
During the start it draws twice the current of the full
load.
The Star-Delta starter is manufactured from three contactors, a
timer
and a thermal overload. The contactors are smaller than the
single
contactor used in a Direct on Line starter as they are
controlling
winding currents only. The currents through the winding are 1/
3
(58%) of the current in the line.
There are two contactors that are close during run, often
referred to
as the main contractor and the delta contactor. These are AC3
rated at
58% of the current rating of the motor. The third contactor is
the star
contactor and that only carries star current while the motor
is
connected in star. The current in star is one third of the
current in
delta, so this contactor can be AC3 rated at one third (33%) of
the
motor rating.
