One of the most important and complex tasks to be carried out in the railroad environment is the weighing of trains and freight cars. As a result, due to this need, there were several ways to carry out this measurement, thus using, as in any other area, a scale. One of these models is the so-called static scale.  <\/p>\n\n\n\n

As you can deduce from the nomenclature used in your name, a static scale performs the weighing process as soon as the railroad asset is completely immobile. The measurement in these cases occurs by difference in gross weight versus tare weight.<\/p>\n\n\n\n

In order to have their operation guaranteed, it is necessary that this model of weighing equipment has approval by INMETRO (National Institute of Metrology, Quality and Technology). In addition, it must also be located in specific positions depending on the activity that will be performed. <\/p>\n\n\n\n

Therefore, when loading wagons, for example, the scale must be positioned below, after or in adjacent lines of the loading silos. In the discharge, before or in adjacent lines or together with the hopper. Given this scenario, do you want to know more about this scale model? Then read on and learn more about the static scale, the advantages and disadvantages of conventional equipment and a new technology that has been used in railroad weighing.  <\/p>\n\n\n\n

When thinking about a static railroad scale, the first thing that must be associated with this equipment is its precision potential. Unlike what normally occurs with the dynamic scale, this scale model guarantees greater accuracy of the weight being loaded.<\/p>\n\n\n\n

That is, when a greater guarantee of the cargo being transported is needed, as in the case of the transport of gold or precious stones, for example, the static scale is used as a way to assist in this process. Thus, greater reliability at this point is in favor of the use of static scales.<\/p>\n\n\n\n

In addition, another factor that is beneficial in relation to this type of scale is the issue of its maintenance. As it is an equipment that has been used for many years in the railroad sector, there are several companies that carry out the maintenance process, whether preventive or corrective. Thus, this service becomes more economical and easier to find, which is no longer the case with dynamic scales, which require a greater degree of specialization.  <\/p>\n\n\n\n

Disadvantages  <\/strong>of static scale<\/h2>\n\n\n\n

Based on a technology that no longer matches the dynamics of the current market, static scales have many disadvantages. We have listed some of them below. Look: <\/p>\n\n\n\n

Need for civil works <\/strong><\/h3>\n\n\n\n
\"Necessidade<\/figure>\n\n\n\n

The first fact that jeopardizes the use of static scales is the installation method. For it to be possible to put a scale of this model into operation, it will be necessary to carry out a civil construction work, a gap, which requires more work and also more time needed to implement it.<\/p>\n\n\n\n

Thus, the construction of a static railroad scale is carried out with a ditch and the use of built-in load cells for static application. These load cells support a mobile platform, from which it will be possible to measure the weight of the railroad asset that is on the platform. To be clear, the installation of static scales goes through five central points: <\/p>\n\n\n\n
