Innovative continuous screw unloading technology tailored for bulk grain, thermal coal, and mineral logistics with high reliability and low power consumption.
Japan’s maritime infrastructure is undergoing a comprehensive transition toward operational decarbonization, seismic safety, and advanced automation. With major coastal industrial clusters located around Tokyo Bay, Ise Bay (Nagoya), and Osaka Bay (Hanshin Port), continuous barge and ship unloaders represent a mission-critical technology for raw material supply chains.
Unlike conventional grab bucket unloaders that generate significant airborne particulates and material degradation, modern continuous screw barge unloaders provide fully enclosed material handling corridors. This makes them ideal for discharging imports of biomass pellets, thermal coal, clinker, cement, grain, and chemical fertilizer directly into inland distribution networks while complying with Japan's stringent Air Pollution Control Act and Ministry of the Environment standards.
Designed to comply with rigorous Japanese Industrial Standards (JIS) and coastal structural criteria, our unloaders feature low-center-of-gravity gantry kinematics and active wind-anchoring locking mechanisms.
From the counter-rotating feeder head to the internal vertical and horizontal screw conveyors, transfer points are totally sealed, eliminating ambient spillage and fugitive emissions.
Adapting heavy cargo unloading equipment to specialized Japanese industrial ecosystems, from biomass conversion power plants to high-density flour milling terminals.
Seamless handling of thermal coal, wood pellets, and palm kernel shells (PKS). The enclosed screw conveyor avoids dust explosions and prevents moisture ingress during rainy typhoon seasons.
Integrated high-torque screw feeders with specialized wear-resistant alloy flights easily manage abrasive ground granulated blast-furnace slag (GGBS), clinker, and fine bulk cement.
Gentle handling prevents grain breakage while meeting food-grade hygiene standards. Enclosed systems protect hygroscopic fertilizers from marine humidity during offloading.
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.
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 across world-class deepwater and river terminals.
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.
To serve the Japanese market, we provide tailored turn-key manufacturing, IoT-based remote condition monitoring, complete spare parts supply, and Japanese-compliant electrical and safety integrations (JIS, JEC, and localized SCADA control systems).
