About MASSA
Manufacturer of rail scales and logistics technology. Technology that improves performance, cuts costs and increases efficiency with every tonne weighed.
Rail Weighing That Generates Savings
MASSA is a Brazilian manufacturer of weighing systems and logistics solutions, with a proven track record across every heavy sector: agribusiness, mining, coal, cement, steel, ports, scrap and fertilizer.
In-house manufacturing and end-to-end integration. Our proposition to the rail market is to deliver technology and data that produce a direct result: an independent weight verified on the line, measurement by axle, bogie and railcar that flags load imbalance, and real-time information to avoid overweight charges, recover freight overbilling and reduce in-transit losses. And we weigh with stops, advances and maneuvers, without losing the measurement.
On top of that, we have SIMMSOFT, a management software developed by MASSA that turns every weighing into an auditable record. It reconciles origin and destination weight, integrates railcar reading via OCR/RFID, sends real-time alerts and connects to your ERP and fiscal system, the data layer that turns the scale into proof.
