Customizable solutions
for weight enforcement
It is a common practice in
almost all countries around
the world to enforce the weight
of vehicles. Everyone is aware of
the importance to protect the
road network from damages
and, primarily, its users from
accidents.
However, there is an
immense diversity related to
climate, type of roads, traffic
intensity and availability of
resources, not to mention the
legislation of each country that
determines not only the features
of the equipment that will be
used but also the method of how
the measurement must be
carried out.
Different approaches
In Europe, the check performed
on the spot is done with two
portable wheel load scales and
four levelling mats, measuring
axle-by-axle. In the USA, it is
completed in one operation with
the same number of scales as the
wheels. In just a few countries
worldwide, the weight-inmotion
(WIM) systems can be
used for direct enforcement. In
others, the enforcement is
performed directly by the police
or by private companies with
the support from the police to
apply the fines where
appropriate. Everyone has the
same goal to weigh the loads.
The more rigorous the
controls become, the greater the
demand for weighing systems
by the private industry, where
the needs can be so variable as
the number of companies.
Developing solutions for the
needs emerged from this
heterogeneity might represent a
big challenge for the weighing
systems providers.
Haenni Instruments, which
has produced mobile scales for
the police worldwide for 45
years, took on the challenge of
seeking solutions for the
demanding market of weight
enforcement. The Haenni scales
have the highest international
certifications such as OIML and
EU type approval, and can
operate in a range of
temperatures from -20C to
+60C. The variety of types, sizes
and ranges enables their use in
different applications. The data is
transferred to multifunctional
software, which will calculate
the axle load, subtotal and total
weight of vehicles.

can be performed with
a compact and efficient
portable system
on the computer, configuring
and managing the devices.
Using simple HTTP requests, it
is possible to capture JSON
formatted data and process it in
any programming language.
In order to use the custom
application for legal metrology,
a certified data storage system is
required. To simplify the
development of the customerspecific
solution, the WebServer
has an approved data storage
directly built in. The storage is
certified for static Haenni scales
WL 103, WL 104 and WL 108.
New systems
As the weight enforcement is
only part of a global check –
which includes the
documentation of the vehicle
and of the driver, the
roadworthiness, the tachograph
records, the tires’ conditions
and eventual mechanical faults
– there might be the need to
integrate the data collected in a
pre-existing operation program.
For the ones who want to use
their own application, Haenni
has recently developed a feasible
solution to facilitate the difficult
task of performing weight
checks, whether conducted
by an official enforcement
or at a self-check spot.
The Haenni WebServer is a
valuable tool for those who want
to build their own software.
Every new device or feature will
be added to the WebServer,
which means that with little or
no modifications the custom
processing software will be able
to handle new Haenni devices
or features. The WebServer is a
