Cases CARAJÁS

The objective of MASSA as a company is to present the best solution for the client, and that the balance is a quick return investment.
Our product is the only one that allows maneuvers without data loss and, some companies are optimizing the loading of the wagons, using their maximum capacity.

This is the case of Carajás, in which 3 In Motion Rail Scales were installed between two silos. The first weighs the tare weight of the wagon, then “gross loading” is done in the first silo. Our company stands out for technological innovation and constant improvement, seeking the best solution for your business, striving for precision and optimization in the weighing process, providing extensive technical assistance, with over 15 years of expertise in the railway sector.

The MASSA Project in Carajás

An intermediate BFD, which shows the weight of the wagons in 4 quadrants - information that arrives to the operator in just 9 seconds -, in order to make a final fine loading in the second silo, supplying the empty spaces of the wagons evenly, without exceeding the capacity of security.

Then we weigh the gross BFD to consolidate the net weight and its individual billing. In addition, the BFDs present the total weighing of the composition, informing the productivity per operational shift. Anyway, after loading the wagons go through the final weighing of the gross BFD and continue on to the port.

Before this operation, each wagon started with an average of 4 tons below the safety capacity and with a disproportionate distribution of the load inside the wagon, which could cause derailments. With the BFDs installed, in addition to improving road safety, the added value per wagon increased.

Just multiply the 4 tons by 4500 wagons / day and see how a good operation and an efficient balance are fundamental for the optimization of the process and profits. Our company stands out for technological innovation and constant improvement, searching for the best solution for your business. , striving for precision and optimization in the weighing process, providing extensive technical assistance, with over 15 years of expertise in the railway sector.

Which In Motion Rail Scale are in Carajás?

Installed Structure

8 Scales, of which: 3 Tare Scales / 3 Gross Scales / 2 Intermediate Scales - Working Conditions: Aggressive - SIMM S-02 (tare and gross) and SIMM S-05 (intermediate) scales with IP68 protection.

Loading in volumetric semiautomatic with TOP-OFF

In this model, there is a main loading silo integrated with a secondary post silo. The secondary silo complements the loading carried out in the main silo, in order to optimize the use of the wagon.

In Serra Norte, this loading model was installed in silos 1 and 2 (added to silos 35 and 36, respectively). The main silo carries approximately 90% of the dimensioned load (target weight) for the type of wagon positioned (GDT or GDU). An intermediate BFD determines the gross weight of the loaded wagon and informs it to the Top-off supervisor, who will dimension the load to be supplemented on the wagon (approximately 10%). The load distribution in the Top-off silo is guided by a profile identifier, seeking a balanced longitudinal distribution.
