BOSCHE wheel load scales - specialists for mobile axle load measurement
Wheel load scales are for the mobile measurement of axle loads on vehicles. The optimal weight distribution on the individual axles of a vehicle is a basic requirement for safe load transport. Use a BOSCHE wheel load scale to check the axle loads and total weights of vehicles such as cars, motorhomes, delivery vans, articulated lorries and construction site vehicles (heavy duty). The scales are all calibratable and highly accurate. Read more...
Functional and precise wheel load scales
A wheel load scale consists of at least two platform-like weighing bridges which are either operated stationary or as a mobile and handy version. The location-based wheel load scales (sometimes also called vehicle scales) can either be placed above ground (e.g. as ramps) or embedded in the ground. If only two platforms are used, each axis is measured individually and the data is then added up to create a total value. Alternatively, a weighing terminal can be connected, which automatically adds up the two weighing values. With mobile wheel load scales, up to 16 weighing platforms can be connected to each other at the same height. They are ideal for checking arrivals and deliveries and can also be used to check for possible overloads.
Various platform sizes are available:
| Wheel load scale RWS | Wheel load scale RWM | Wheel load scale RWM |
|---|---|---|
 |
 |
 |
| 400 x 565 mm 1,500 -15,000 kg |
450 x 750 mm 6,000 -15,000 kg |
500 x 950 mm 6,000 -20,000 kg |

Measuring method
Basically, there are two different measuring methods for determining the axle load with a wheel load scale: dynamic and static wheel load weighing. In the first variant, the vehicle drives over the weighing platforms to determine the weight at a constantly low speed of a maximum of 5 km/h. With the static method, however, the wheels of the car or truck are positioned exactly on the weighing platforms of the wheel load scale, i.e. within the centering bands. The driver then releases the brake and switches off the engine. The wheel load of the vehicle can now be weighed while standing. For both methods, measurement is not recommended for means of transport with almost or completely flat tires.
Optimal weighing conditions for the wheel load scale
For safe and accurate weighing, not only the weighing modules should be tailored to the process, but also the surface. It is always advisable to choose a flat surface for the scales with a hardness of at least 100 kg/cm². It also makes sense to install an adjusted height range before and after the weighing platform, which is ideally twice as long as the longest vehicle to be measured. If you regularly measure semi-trailers, tank trucks or construction vehicles with more than two axles, the BOSCHE height modules are ideal. We are happy to supply you with pit frames for fixing wheel load scales at ground level.
To optimally distribute the axle load, place each wheel on a weighing module of the wheel load scale. You can then adjust the height of the vehicle's suspension struts so that the weights on the left and right front as well as the left and right rear have the same value. It is important that the wheel load is always balanced diagonally. This means: If you want more load on the axle at the front left, the shock absorber must be screwed up at the rear right.
