Currently, there are several systems for weighing trucks.
1) Mechanical truck scales, in which the load is transferred from the platform through a linkage and the force is displayed on the weight scale.
2) Electronic truck scales on strain gauges are modern electronic equipment based on the transmission of an electrical signal caused by mechanical stress, which is then converted and recorded depending on the type, analog or digital.
Truck scales are divided into two main types of installation
On the surface - all types of scales, mobile / underlay, stationary
Mortise (Undersurface) - Stationary Scales Only
The article is intended for understanding the process of separate weighing on different types of truck scales.
The method of separate weighing on truck scales installed on the surface
In such a weighing technique, there is always a moment of shifting the center of gravity, this is especially common with underlay / portable scales.
Especially when the axles of the car are located in close proximity to each other, there is a redistribution of the load.
An example is a three-axle tractor. In the case when all three axles are independent and have rigidity, in order to avoid redistribution of weight, it is necessary to simultaneously raise all axles to the same height.
Separate weighing on mortise truck scales
On this type of truck scales, the probability of weight redistribution is minimal due to the same level of arrival and scales, since the level of the vehicle axles is approximately equal.
Do not forget about such an important factor as the slope, because the load displacement often depends on it. But this is not the only factor affecting the correctness of separate weighing.
In the absence of full-sized truck scales that allow weighing freight transport in one run. It is necessary to take into account important factors in separate weighing that affect the final weighing result. To know the exact weight, we recommend that when purchasing new truck scales, take into account the maximum length of the freight transport through which the weighing will be carried out.
