Mobile axle weighing systems are vehicle weighing equipment used in various sectors of activity. Incorrect installation of these weighing systems can lead to significant measurement errors. What mistakes should absolutely be avoided so as not to lose accuracy? In this article, we will review the three most common errors when installing mobile axle weighing systems and explain how to avoid them in order to maintain optimum weighing accuracy.
A mobile axle scale is a weighing device used to determine the weight of a vehicle by weighing each axle separately. It is mainly used to check load limits and to measure incoming and outgoing materials. The mobile axle weighing system features the latest in-motion weighing technologies, allowing vehicles to be weighed while driving. It is used on roads or concrete slabs. The mobile axle weighing system can be easily moved from one area to another or transported from one site to another as required.
Installing a mobile axle weighing system on a sloped or uneven surface leads to the load being transferred between axles and inaccurate measurements. Similarly, unstable ground generates suspension movements that accentuate the load being transferred between the axles. Weighing results are not accurate or repeatable.
The flatness and stability of the ground are essential for obtaining optimum measurement accuracy. A mobile axle weighing system must be installed on a flat concrete, bitumen or asphalt surface. Compliance with these requirements means that trucks in motion can be weighed accurately.
The use above ground of a mobile axle weighing system with only access ramps causes over-weighing. The uncompensated height of the scales results in an angle between the axle being weighed and the unweighed axle(s). Measurement errors can be greater or lesser depending on the height of the mobile axle weighing system and the distance between the axles.
The use of a levelling track is essential in order to reproduce a flat surface before and after the mobile axle weighing system. To be accurate, weighing one axle in a group of axles must be carried out with the axle at the same height. Using a mobile axle weighing system with a rolling lane reduces the risk of the load being transferred and guarantees accurate results.
Installing a mobile axle weighing system before or after a curve can cause under-weighing. A long vehicle will find it difficult to line up and may end up with one or more wheels "straddling" the ground between the scales and the ground. This can cause measurement errors by minimising the load on the axle(s).
It is recommended to install a mobile axle weighing system on a straight section of the roadway. the length of this straight line must be equal to twice the length of the longest vehicle to be weighed. The vehicle must travel at a constant speed without making any bends until the last axle has crossed the scales.
Incorrect installation of a mobile axle weighing system can distort measurements and affect the accuracy of results. Make sure that the concrete or asphalt area is flat and stable before installing the mobile axle weighing system. Uneven or unstable surfaces can cause load transfers. Use levelling accessories before and after the mobile axle weighing system. Using a levelling track reduces the risk of the load being transferred and guarantees accurate results. It is recommended to install a mobile axle weighing system on a straight section of the roadway. The vehicle must travel at a constant speed without making any bends until the last axle has crossed the scales. It is important to follow these installation recommendations to maintain optimum weighing accuracy.

In many industries, vehicle weighing is an essential pillar for determining the weight of goods carried. It also makes it possible to respond to the regulatory aspect of the activity and to prevent overloads. Proper selection of equipment such as weighbridges and axle weights is of utmost importance. These devices play a fundamental role in the precise management of vehicle weight and loading. Weighbridges and axle weights have distinct designs and functions. This comprehensive guide aims to enlighten professionals and decision-makers in the process of acquiring these essential equipment. This manual provides an in-depth overview of the different technologies, capabilities, and specifications of weighbridges and axle weights. It allows a clear understanding of their features and benefits. Through a detailed analysis, we will address the key criteria to consider for a wise choice, adapted to the specific needs of each company.
