Definition of the wheel-weighing system
Definition of the axle-weighing system
USE A wheel-weighing system consists of as many platforms as many vehicle wheels to be weighed and is
used to weigh the whole vehicle in a single step.
USE An axle-weighing system consists of two platforms and is used to weigh the whole vehicle by adding
together the various axles.
A wheel-weighing system provides the following benefits:
• weighing accuracy comparable to that of a weighbridge (0.05% end-of-scale);
• less expensive than a weighbridge and no masonry work is required;
• display and printing of the weight of the single wheels, all combinations (axles, right side, left side, front, back, etc.) and the total
weight of the vehicle;
• calculation of the centre of gravity of the vehicle (depending on the setup).
An axle-weighing system provides the following benefits:
• overload control on the axle;
• easy to install and use;
• display and print-out of the axle weight and total weight.
1. Climb onto the platforms, engage the first gear, stop the engine and
release the brake.
2. Acquire the weight
(refer to the user manual of the main indicator).
Manual static axle weighing
To achieve the best weighing accuracy, while acquiring the weigh, release the parking brake and turn off the engine.
If the vehicle has self-levelling suspensions, disable them or use levelling modules.
Place the wheels at the centre of the signalling strips on the loading platform.
!
1. Climb onto the platform and stop there.
Each axle is acquired when the dedicated button is pressed. System that can be made with both wireless and wired platforms.
2. Acquire the weight
(refer to the user manual of the main indicator).

WWS 7
Pass at the lowest possible speed and ensure this is constant (5 mph). Do not brake during the weighing process.
Throughout the weighing cycle, we recommend ensuring all wheels are at the same level, by using levelling modules or pit
frames to achieve the optimal weighing performance.
The minimum recommended length of a flat surface must be at least twice that of the longest vehicle to be weighed
(see page 16).
!
1. Pass on the platform at low speed.
Each axle is automatically acquired as the vehicle passes over the platforms. System that can only be made with wired platforms.

WWS 11
Installing the platforms
Choosing the weighing area
RECOMMENDATIONS FOR AN OPTIMAL SYSTEM INSTALLATION
WWS platforms can be installed on any type of surface, though for optimal use and to obtain the best weighing results we recommend:
• Choosing a weighing area that is large enough to allow easy manoeuvres for vehicles under 100% safe conditions.
• Prefer flat and well-levelled surfaces, with an slope of less than 0.5% and a minimum length equal to twice that of the
• longest vehicle to be weighted; flat surfaces with an unsuitable length can affect the accuracy of the weighing process.
• Prefer use on hard surfaces, concrete or asphalt with a hardness of at least 100 kg/cm2(usual value for reinforced concrete).
• The bottom surface under the weighing area must withstand, without any failures, concentrated loads of at least 1.5 times the maximum
capacity of the module.
• Prefer environments where the temperature is between -10°C and +40°C.
• We recommend creating a dedicated area with guardrails or other solutions forcing the driver to transit at a reduced and constant
speed. Where possible, install access barriers to prevent transit during periods when the system is not used.
WARNINGS
• Avoid rough terrain or uneven surfaces.
• Avoid areas at risk of flooding.
• Avoid common transit areas: WWS platforms are not designed to be used as road surfaces and, therefore, they must only be used at
the time of weighing according the conditions stated on (see page 14).
<0,5%
• In “axle-weighing” mode, we first recommend creating a well-levelled area and then the weighing platforms, which must be of a
suitable length.
• In “axle-weighing” mode, we do not recommend weighing vehicles carrying liquids.
• The weighing performance can be affected by the type and state of maintenance of the vehicle weighed.
• Once you have optimised the system, we recommend always keeping the same direction of travel.
The levelled area is required when you need to weigh vehicles with more than two axles. In any case, it is advisable in all axle
weighing applications to ensure top performance levels. To create the levelled area, there are levelling modules available (see page
16) or the pit frame to fix the platforms flush with the floor (see page 17).

How to position the platforms
To make the positioning and adjustment of the platforms easier, you can use the built-in wheels:
• Before positioning the platforms, ensure that the vehicle’s engine is off, with the first gear engaged and the parking
brake activated.
• Never stand in front or behind the vehicle during positioning operations.
• Pay the utmost attention to the vehicle when it is moving.
!
To speed up operations without taking measurements, we recommend positioning the platforms directly in front of the wheels of the
vehicle to be weighed:
1. 2. 3.
Keep your back straight when lifting the platforms.
When installing the scale, we
recommend wearing gloves
and work shoes.
!
!
Pay the upmost attention to
your hands and feet when
positioning the platforms.

WWS 13
Also ensure you do not pass cables in transit areas, under the load cells and under the central box of the platform.
= Position of the cable
We recommend placing the cables as follows

• In case of platforms with a built-in indicator, the indicator must be facing outwards to allow for a correct transmission of detected
weighing data.
• The built-in antenna must be facing upwards.
• Do not pass with the vehicle over the screen of the platform.

How to use the platforms correctly
Transit area Positioning bands
!
In case of wireless platforms, to preserve the correct operation of the built-in weight indicator, we recommend avoiding
transit over the display, thereby preventing accidental scratches. Respect the transit area and positioning indicated in the
previous drawing.

WWS 15
Maintenance of the platforms
We recommend periodically checking the correct operation of the platforms to ensure accuracy over time.
This is checked with sample weights by specialist personnel to obtain an official calibration certificate.
You can also easily check the operation of the platforms yourself by proceeding as follows:
Place one (1) or two (2) platforms on the edge of the weighbridge and proceed with the weighing of individual wheel or the first axle.
Make sure the weights displayed by the two systems correspond.

• Remove from the weighing area and the area under the WWS platform any debris that may prevent the loading surface from ben-
ding correctly.
• Clean the platform with non-aggressive substances.
• Periodically check the condition of the connection cables.
• In case of prolonged non-use, we recommend fully charging the battery before putting away the system.

Levelling modules for axle-weighing systems
Choosing the length of the area levelled with the modules
USE
They are used to create weighing lanes according to the desired length to align all the wheels of the
weighted vehicle, thereby considerably improving the weighing accuracy. This also improves the quality
of transit surface and reduces the uneven nature of the ground.
APPLICATIONS Ideal for mobile axle weighing stations.
ACTIVATION The levelling modules are optional accessories.
The best weighing condition is obtained by creating a levelled area whose length is equal to twice that of the longest vehi-
cle to be weighed.
Ideal installation
The minimum length of the area depends on the type of vehicle to be weighed. For instance, the recommended length for a 5-axle vehi-
cle is 3.5m before and after the platforms, so as to keep the axles of the engine and those of the trailer at the same level.

WWS 17
Pit frames for floor-level installations
USE They are used to integrate the platforms into the roadbed, thereby improving the distribution of the loads.
APPLICATIONS Ideal for fixed axle weighing stations.
ACTIVATION The pit frames are optional accessories.
As an alternative to standard pit looms, to achieve greater flexibility in terms of use you can create a pit of an adequate length inside
which you can adjust the distance between the platforms, while still keeping them at floor level:
Standard pit frame
Additional ramps for easier up/down movements
USE Used to make it easier to move the platforms up and down.
APPLICATIONS Ideal for vehicles with wheels featuring a particularly small diameter or for vehicles/aircraft moved with
towing equipment.

Avoid:
• Sharp manoeuvres
• Rapid lowering of the load
• Accidental crashes on/to the
platforms
Thanks to their modularity, these handy platforms can be moved in any position, directly below the point in which the structure must be
weighed. To use them correctly, please follow this procedure:
1. lower the load up to an approximate height of 10 cm from the ground
2. position the load over the platforms
10 cm
3. lay the load slowly on the platforms
Weighing of objects or structures
!
With wireless platforms:
• If the platforms have an integrated indicator, this must point towards the external side, in order to allow a correct transmis-
sion of the weight reading data.
• The integrated antenna must point upwards.
• Do not position the load on the platform screen.

FAQ - Frequently Asked Questions
How to increase the accuracy of an axle-weighing system
Communication problems in wireless systems
The scale will bend when loaded
The keypad is locked / the platform does not turn off
The weighing accuracy in axle-weighing mode is influenced by several factors:
• Type of weighing area: it must comply with the levelling conditions See page 11.
• Remove any unevenness between the axles by using the levelling modules or pit frames.
• Vehicles with several axles close to each other require a surface that is levelled correctly See page 16.
• Type of vehicle: vehicles with self-levelling suspensions can affect the weighing process; disable them if possible.
• Transported load: the axle weighing process does not allow you to weigh vehicles that carry liquids.
• Follow all the instructions in this manual to obtain optimal weighing results.
• If the system has been optimised for a direction of travel, using it in other direction might reduce the weighing accuracy.
• Ensure there are no other devices communicating on the same frequencies
• Move the tool on the platforms
• Make sure there are no obstructions between the indicator and the platforms
• Turn the indicator outwards and the radio antennas upwards
• Reload all the platforms and indicators
• Ensure there are no systems on the same frequency (868 MHz)
• The bending of the loaded weighing surface makes the operation of the load cells easier, thereby ensuring optimal wei-
ghing accuracy. Before installing the platforms, always remove any dirt and debris from the floor under the platform.
• If the automatic keypad lock function has been activated, you cannot do anything on the keyboard, including turning off
the platform. See page 5 to reactivate the keypad.
