Installing an in-motion axle weighing system on a farm can provide a number of benefits for grain stock management. In this article, we'll look at the different types of in-motion axle weighing systems suitable for agricultural tyres, the benefits they offer and provide practical advice on how to install them. By following our advice, you can considerably improve the management of your grain stocks and optimise your transport operations.
In-motion axle weighing systems are alternative weighing solutions to weighbridge, enabling agricultural and road vehicles to be weighed while moving. There are several types of in-motion axle weighing systems, not all of which are compatible with large low-pressure tyres. We will mainly discuss the two types most commonly used on farms for grain storage.
Mobile in-motion axle weighing systems are weighing systems used mainly above ground. They enable farmers to quickly weigh the load on farm machinery and lorries. When the vehicle drives over the weighing plates, the weight data is displayed on a screen and recorded. Mobile in-motion axle weighing systems are easy to use. They are particularly useful for farmers with several storage sites. The weighing plates can be easily transported from one site to another. The accuracy of mobile axle weighing systems can be affected by the flatness of the ground on which they are installed.
Recessed in-motion axle weighing systems are weighing systems installed in a concrete slab. They enable precise measurement of the weight of agricultural tractors, tippers and semi-trailers. The installation cost is higher than for mobile axle weighing systems, but they offer better measurement accuracy and greater durability. Recessed in-motion axle weighing systems are recommended for farms that have a permanent storage site. Recessed in-motion axle weighing systems are also suitable for large semi-low-pressure and low-pressure tyres.
Accurate management of grain stocks on a farm is essential to optimise sales and reduce costs. In-motion axle weighing systems are versatile alternatives to weighbridge. They offer many benefits while being affordable:
Whether for an above-ground or in-ground installation, it's important to choose a flat area in a straight line. The length of this straight line must be at least twice the length of the longest vehicle to be weighed.
A mobile in-motion axle weighing system must be installed on a flat concrete or asphalt surface. The use of levelling accessories or a levelling track is essential for accurate and reliable weighing. It is essential to reproduce a flat surface before and after the in-motion axle weighing system to avoid transferring load between the weighted axle and the unweighed axle(s). To compensate the height of the weighing plates, you can use low-cost wooden wedges or battens, which have excellent compressive strength. A minimum length of 3.50 metres before and 3.50 metres after the in-motion axle weighing system is required.
An in-motion axle weighing system requires a minimum layout for long-term use. Installation consists of creating a flat concrete slab at least 7 metres long before and after the in-motion axle weighing system. Non-concrete areas can be made using compacted gravel on the same level as the concreted slab. The use of a geotextile underlay improves its effectiveness. Installing the weighing plates in the central reservation is quick and easy. In-motion axle weighing systems are delivered calibrated and ready to use.
The use of in-motion axle weighing systems on grain, mixed crop and livestock farms has become increasingly widespread. However, to obtain accurate and reliable weighing results, it is important to follow the recommendations of a specialist such as Captels. Weighing plates must be suitable for low-pressure agricultural tyres, particularly with regard to the tyre crushing in the direction of travel. To use in-motion axle weighing systems effectively, agricultural and road vehicles must be weighed at a constant speed without accelerating or braking. On average, up to 10 km/h for a recessed in-motion axle weighing system and for a mobile in-motion axle weighing system. Installation of recessed weighing plates is recommended for optimum weighing accuracy.
In conclusion, installation of an in-motion axle weighing system suited to agricultural tyres can offer a number of benefits for the management of grain stocks on a farm. Farmers can be autonomous when it comes to weighing crops as well as materials entering and leaving the farm. They are able to accurately monitor the quantity of grain stored, optimise shipments and avoid overloads, calculate and improve plot yields, add value to grain and control costs. Mobile and recessed in-motion axle weighing systems are versatile alternatives to weighbridge, offering a host of benefits at an affordable price. When installing an in-motion axle weighing system, it's important to choose a flat area in a straight line and to follow the practical advice for successful installation. Installing an in-motion axle weighing system is a worthwhile investment for any farm looking to optimise its grain, straw and fodder storage and transport operations.
