Truck scale have many other names as well such as weighbridge and the railroad scale. It is a very large scale which is usually constructed on the concrete base and therefore it is fixed there and cannot be moved from place to place. The purpose of this truck scale is that it is used to measure the weigh carried by the truck. Since it is very difficult to unload the truck and then weight every item and then calculate the total weight. The truck scale follows the simple mechanism in which the truck is placed on the truck scale and then the weight is measured and then the cargo is unloaded and then again, the weight of the empty truck is measured. The difference of both these weights are used to determine the weight of the cargo.
There are majorly two major purposes of the truck scales. There are bridges and the areas where the passing fee is dependent on the weight of the vehicle and the cargo in it. The truck scales are mounted on each such posts and used to determine the fee based on the measurement of the weight then the second use is determining the overall weight of the vehicle and the weight that has been loaded in to it. This is how the truck scale prevents the vehicle from overloading and the vehicle is safe from all kind of violations of the overloading. The common use of the truck scale is in those industries which manufactures the bulk items and not only they manufacture it but also moves it from one place to another. Because the weights of all vehicles are measured one time and noted and then whenever the vehicles are loaded these are measured again and the weight of the cargo can simply be calculated very quickly. The industries which make use of the truck scale include the miners, recyclers, and garbage dumpers.
However, traditionally the truck scales are fixed and cannot be moved but now there are portable truck scales as well but the capacity of measuring the weights for the portable truck scales is very much less as compared to the fixed ones. Apart from the less weight capacity, all the other features of the portable truck scale is same as the fixed truck scale which includes the accuracy and the precision as well. The portable truck scales are made from placing wheels of trucks under the concrete base. The units which are used in the measurement of the weights in truck scales are called load cell.
