Specially adapted for the Seine-Scheldt canal network, HAROPA Port terminals, and the Rhône-Saône inland waterway corridor.
Continuous high-efficiency Archimedean screw system engineered for continuous bulk handling of cement and clinker at major river and seaport terminals.
Heavy-duty rail-traveling unloader built for high-throughput chemical powders, mineral fertilizers, and specialized granular goods with automated feeder heads.
Floating barge-mounted continuous screw unloader providing flexible ship-to-ship and ship-to-shore transshipment across inland river docks and estuary terminals.
Proven heavy portal screw unloader handling harsh marine environments, continuous bulk cargo flows, and multi-vessel berthing berths with zero dust emissions.
Navigating the green transition across France's major inland waterways and industrial river corridors.
France possesses the largest inland waterway network in Western Europe, governed predominantly by Voies Navigables de France (VNF). With key logistics axes along the Seine River, the Rhône-Saône corridor, and the major north-European connection via the Canal Seine-Nord Europe (CSNE), the demand for high-capacity, environmentally responsible bulk handling equipment is entering a historic growth phase.
Traditional grab cranes and cyclic bucket systems are increasingly being phased out across French river quays due to stringent environmental decrees, fugitive dust dispersion, high energy consumption, and high cargo degradation. Modern French terminal operators—such as those operating under the HAROPA Port Alliance (Le Havre, Rouen, Paris) and the Port of Marseille Fos—are demanding totally enclosed Continuous Barge Unloaders (CBUs) to meet the European Green Deal and local French ICPE (Installations Classées pour la Protection de l'Environnement) environmental regulations.
"Continuous screw barge unloaders provide French industrial terminals with up to 40% energy reduction compared to pneumatic unloaders and zero dust leakage relative to grab cranes, ensuring seamless compliance with VNF ecological standards."
France is the European Union's premier agricultural producer and exporter of cereals (soft wheat, barley, maize). Bulk grain hubs in Rouen and inland transit silos across Hauts-de-France and Grand Est require continuous unloading systems that preserve grain integrity, prevent dust explosions (fully ATEX compliant), and maintain stable discharge rates across tight barge turnaround windows.
Simultaneously, the Grand Paris Express urban mega-project and regional infrastructure renewals create massive demand for inland transport of aggregates, ground granulated blast-furnace slag (GGBS), fly ash, and clinker. Transporting bulk construction materials via 1,000 to 4,400-tonne push-tow convoys directly into Parisian river quays cuts thousands of truck journeys, provided quayside continuous unloaders can operate silently and dust-free in urbanized riverbanks.
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.
100% dust-free pneumatic & mechanical screw transfer for sustainable concrete manufacturing.
Anti-corrosive, non-degrading screw flights designed for urea, NPK, and phosphate logistics.
High-torque, wear-resistant continuous unloader setups for power stations and metallurgical plants.
Extreme abrasion-resistant composite alloys capable of handling highly abrasive mineral clinker.
Gentle seed handling, low breakage rate, and explosion-proof ATEX compliant grain transport.
Next-generation bulk unloading technologies tailored to the regulatory, environmental, and operational standards of Western Europe.
Equipped with hermetically sealed Archimedean screw shafts and negative-pressure extraction filters, eliminating dust escape at the riverbank and protecting adjacent urban communities in France.
Unlike cyclic grab cranes that experience variable filling rates and cargo spillages, continuous screw unloaders deliver continuous peak rates up to 1,500 t/h with automated hold clean-up capabilities.
Integrated Siemens/Schneider PLC systems with AI-driven load-sensing controls, real-time vibration diagnostics, and remote European cloud monitoring for predictive maintenance.
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 global bulk handling terminals.
1,000 ktons annual capacity delivering continuous, dust-free bulk mineral and cement unloading in strict environmental zones.
600 tons/hour continuous high-torque screw ship unloader handling continuous coal and power plant supply lines.
Heavy-duty portal rail-traveling screw ship unloader engineered for continuous bulk marine terminal operations.
High-efficiency multi-commodity continuous screw unloader providing high operational reliability and low power consumption.
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 worldwide, and is now fully primed to deliver direct factory-backed solutions to French and European river ports and industrial terminals.
