Avery
Weigh-Tronix has pioneered static and coupled in
motion weighing of rail vehicles for over half a
century.
With an impressive number of installations in all
continents they are recognized leaders in their
field and have the
largest number of in-motion weighing systems in
operation worldwide. Our innovative
technology allows us to create
solutions which take a different approach than
traditional, more costly methods. The results show
through clearly on
your balance sheet in low life cycle costs and a
short payback time. With total
worldwide service, design, manufacturing,
installation and support, we can tackle any
challenge, anywhere in the world.
The Railroad Track Scales we sell and service
are from quality conscious, ISO accredited,
manufacturers.
The following is representative of what we offer.
It is not exclusive. Please contact
us with your requirements.
Industrial
Applications for Rail Scales
Recycling
/ Waste / Landfill:
Avery
Weigh-Tronix rail scales are used in
recycling plants:
To monitor, while
trains are in-motion, net
amounts of scrap
products and sub-products
entering the plant.
To control amount
of product being loaded before
cars leave plant.
For commercial
transactions (invoicing).
Chemical
& Petroleum Industries:
Many customers in this
industry weigh their tanker and cars on
Avery Weigh-Tronix systems. Multiple wheel
weight recordings ensure accurate
measurement of liquid carrying vehicles.
Vehicles are weighed statically or
dynamically “full draft” where possible to
ensure accuracy under conditions where the
product being weighed may be moving within
the tanker.
The static application is also used for
loading control where live weights can be
used in manually or automatic loading
processes.
Other typical applications:
Measuring
the amount of goods dispatched
(car to car
& total train)
Measuring products
arriving against manifest.
Monitoring
tanker cars (arrival
weight over departure
weight) for hazardous
leakage.
Used where heavier
than air explosive gases are
present (Weighline does not
trap gases)
Check LPG
delivered in bulk against
manifest and invoiced
quantities.
Combined with
Radio Frequency Automatic
Vehicle Identification (AVI)
to monitor automatically own
fleet of freight and tanker
cars.
As a management
control tool, integrated to
the plant network.
Some
chemical plants generate revenue
by weighing tankers or cars for
other users of the rail siding
in the same petrochemical
complex.
Mining
& Quarrying:
Some
of the applications of train
weighing systems that contribute to
improve overall productivity in
mining and quarrying are:
Optimizing loads
and transport of minerals.
Measuring amount
of products transferred
between production sectors.
Detecting unevenly
loaded and overloaded cars.
Monitoring
continuous loading.
Integrated with
load out stations for
simultaneous loading and
dynamic weighing of bulk
product.
Steel Industry:
Static
and Coupled In-Motion Weighing Systems
are widely used by the steel and other
metals industry to:
Weigh
torpedo, ladle, slab, and coke
oven charge cars.
Check-weigh scrap
metal and in-coming trains.
Monitor the
transfer of materials and
products between profit
centers.
Monitor cars,
combined with radio frequency
Automatic Vehicle
Identification (AVI), in fully
automatic operations.
Communicate with a
host computer to keep track of
weighing transactions in real
time.
Vehicle
Workshop and Rail Maintenance
Facilities:
Both
static and in-motion systems are
installed in workshop depots and
maintenance facilities to weigh vehicles
of all kinds including locomotives,
freight cars and passenger coaches.
These
systems can be installed to provide
wheel, axle, truck, and complete vehicle
weights for safety purposes to ensure
correct balancing following either
manufacture or repair.
Railways
/ Freight Industry:
Internationally,
the Railways Industry
uses static and
Coupled In-Motion
Weighing for a number
of reasons including:
Freight
Revenue
Collection -
Rail companies
and freight
forwarders
measure
vehicle
weights in
order to
charge
according to
weight carried
Vehicle
Screening -
Rail companies
and freight
forwarders
measure
vehicle
weights in
order to check
for undeclared
loads. E.g.
Freight
forwarders may
pay Rail
Operators for
the transfer
of a train
with loaded
containers to
a designated
port and then
for the return
of them empty
to the
original
destination.
The Rail
Operator may
find that the
containers are
not always
being returned
empty. This
can result in
additional
charges to the
Freight
Forwarder for
return trips.
Overload
and
Eccentrically
load detection
- Rail
companies need
to ensure cars
and trains are
not overloaded
or
eccentrically
loaded for the
following
reasons:
o
Overloads cause
damage to
tracks, bridges
and cars
o
Overloads are a
safety hazard as
they cause the
braking capacity
to be exceeded
o
Eccentric
loading can
cause
derailments
Power
Generation:
Power
generation relies on rail scales
to:
Monitor trains
continuously in-motion in a
"carousel" type operation
between port (or mine) and
generating plants weighing
trains 24 hours per day and
365 days per year with very
brief intervals between
trains.
Obtain net weight
of raw materials.
Capture
and transmit data in real
time to host computers for
management control.
Operate
load control systems while
trains are on the move.
Port
Authorities:
Trains
in and out of ports are weighed
statically or dynamically for safety and
commercial purposes:
Trains are weighed
as they enter and leave the
port to accurately measure
tare, gross and net weights of
cars and of total train.
Overloaded cars
with imbalanced loads are
detected and removed before
trains leave the port.
In some instances,
the systems can significantly
contribute to reduce or
eliminate derailments.
Cement
Industry:
Cement
and other powders tend to stick to
hopper cars that carry the product in
bulk. After some time, cement may become
unstuck. Tare weights, therefore, may
change frequently.
Generally,
the tare written on each car has been
used to calculate net weight of the
product transported. Because of the
frequent real tare changes mentioned
above, inventory variations between
stock takes can be important and
directly affect the Profit &
Loss Account.
Rail
scales therefore calculate the
net weight of product using the
real tare of each car. The
information is instantly printed
and transmitted to the plant
network:
The rail scale is
integrated to the management
control system in modern
plants.
Data is
transmitted to host computer
by optic fibre, cables or
radio modems.
Rail scales are
used for loading control
purposes (static application).
Invoicing for
product made automatically
when trains leave the plant
(CIMW
application).
Arriving
trains that carry klinker and
other production and
maintenance materials are
weighed on their way into the
plant and, again when they
leave for check weighing
purposes.
Customers tend to
choose rail scales combined
with Radio Frequency Automatic
Vehicle Identification (AVI)
for fully automatic operation.
Cars that entered
the plant can be mixed,
interchanged and be dispatched
on different days or weeks and
in different train
configurations – the system
recalls the stored weight
against the car number read by
the AVI (or keyed-in by the
operator) to calculate the
accurate net weight.
