Engineered for high-throughput operations, these units are designed to optimize dry bulk handling under the demanding conditions of Brazilian riverways and maritime ports.
Brazil stands as a global powerhouse in agricultural exports and mineral production. The country's logistics backbone relies heavily on major maritime gateways such as the Port of Santos, Port of Paranaguá, and the rapidly growing "Arco Norte" (Northern Arc) river terminals along the Amazon and Tapajós rivers. Efficiently transferring dry bulk commodities from river barges to ocean-going vessels or storage facilities is a critical link in this supply chain.
Traditional grab-type cranes are increasingly falling out of favor in Brazil due to their environmental limitations, high energy consumption, and product degradation. The modern Brazilian bulk handling market demands advanced Continuous Barge Unloaders (CBUs) that offer completely enclosed conveying pathways. This technology is vital for preventing dust pollution, protecting grain quality, and maintaining constant discharge rates regardless of weather conditions.
Fully enclosed screw mechanism prevents product loss and eliminates airborne dust, ensuring clean air around urban-adjacent ports like Santos.
Unlike cyclic grab buckets, screw unloaders deliver a steady stream of material, maximizing downstream belt conveyor capacities.
Optimized screw geometry reduces grain breakage, preserving the premium value of Brazilian soybeans and corn during transfer.
We specialize in providing overall solutions for bulk material transfer, storage, and transportation systems, as well as the R&D, design, manufacturing, and sales of high-end loading and unloading equipment for powdery and granular bulk materials.
Our technologies are highly adaptable to the primary commodities driving the Brazilian economy. From the massive grain harvests of Mato Grosso to the imported fertilizers required for the Cerrado soil, our continuous barge unloaders handle diverse materials with unmatched efficiency.
Tailored engineering designs to overcome the geographical and logistical challenges unique to South American waterways.
Waterways like the Madeira and Tapajós rivers experience dramatic water level fluctuations—sometimes exceeding 15 meters between the dry and wet seasons. Traditional fixed unloading structures struggle under these conditions. AOTUO's continuous barge unloaders are engineered with variable-reach vertical screws and flexible, hydraulic-controlled boom systems that adapt seamlessly to changing drafts and river levels, ensuring year-round, uninterrupted grain and fertilizer transshipment.
Coastal shipping (cabotagem) is vital for distributing industrial materials like cement, GGBS, and fly ash from southern manufacturing hubs to northeastern infrastructure projects. Our rail-mounted and fixed screw ship unloaders provide high-speed discharge directly to port silos or truck loading stations, minimizing vessel turnaround times at congested berths in ports like Suape and Pecém.
Brazil imports the vast majority of its agricultural fertilizers (including Urea, MAP, and SSP). These materials are highly corrosive, abrasive, and sensitive to moisture. Our factory designs specialized continuous screw unloaders utilizing marine-grade stainless steel liners, anti-corrosive coatings, and hermetically sealed housings. This prevents atmospheric moisture from degrading the fertilizer during unloading and protects the machinery from chemical wear, extending the equipment's lifespan in tropical climates.
For heavy industrial ports serving steel mills and thermal power generation plants in Ceará and Santa Catarina, high-capacity coal unloading is essential. AOTUO's heavy-duty continuous screw unloaders deliver continuous throughput rates of up to 1000 tons per hour, providing a reliable fuel supply chain with minimal maintenance requirements.
The company's products and services have been exported to countries such as Australia, Korea, Singapore, the Philippines, Vietnam, Malaysia, Indonesia, Sri Lanka, and Russia, and are well-received by customers. Our global engineering pedigree ensures that our systems are built to meet the most rigorous international standards, making them highly suitable for the demanding operations of the Brazilian market.
These global installations demonstrate our capability to deliver reliable, high-capacity bulk handling systems. For the Brazilian market, we leverage this extensive international experience to provide customized solutions. Whether handling grain transshipments in the Amazon basin or discharging bulk raw materials at the Port of Santos, our systems are engineered to achieve maximum uptime, low energy consumption, and strict compliance with local environmental regulations.
Ensuring seamless integration into Brazilian port operations through strict compliance with local safety and electrical standards.
Operating heavy machinery in Brazilian ports requires strict adherence to NR-12 (Norma Regulamentadora 12). This standard dictates rigorous safety measures for machinery and work equipment. Our factory designs continuous barge unloaders with NR-12 compliant physical barriers, dual-channel safety sensors, emergency stop systems, and fail-safe locking mechanisms on all moving parts, ensuring safe operation and smooth regulatory approvals during installation.
Brazil's industrial electrical systems operate at 60Hz, with varying voltage configurations (such as 380V, 440V, or medium-voltage systems for high-capacity terminals). Our electrical control systems and motor configurations are fully customized to match these specifications. In compliance with NR-10, all electrical enclosures, wiring paths, and control panels are designed to ensure safety against electrical hazards under high-humidity, marine-saline environments.
Over the past two decades, AOTUO has dedicated itself to the research, development, and manufacturing of screw ship unloaders, becoming a benchmark for "Chinese products replace imports." Along the Yangtze River and other inland riverbanks, as well as in seaports and docks, its unloading equipment has been deployed across more than twenty provinces in China. Its comprehensive manufacturing and service system has earned widespread acclaim from customers.
Building on this strong foundation, we are committed to extending our world-class service to South America. We offer comprehensive support to our Brazilian clients, including initial site planning, custom engineering design, supervision of installation, commissioning, operator training, and local spare parts supply. Our goal is to ensure that every continuous barge unloader operating in Brazil delivers peak performance and reliable service throughout its operational life.
