One stop solution


In the high-stakes environment of dry bulk material handling, ensuring the structural and operational safety of heavy-lift equipment is paramount. Hangzhou Aotuo Mechanical and Electrical Co., Ltd. (AOTUO), a pioneer in the localization of bulk cement screw unloaders, integrates advanced intelligent control systems and safety protocols into its high-end machinery to manage capacities up to 3000t/h.
The safety architecture for heavy-lift cranes and screw unloaders focuses on preventing structural failure and ensuring operator safety:
Modern equipment relies on real-time data to prevent overloading and ensure environmental compliance:
| Feature | AOTUO Screw Unloader | Traditional Grab Unloader |
| Max Capacity | Up to 3000 t/h | Variable (Highly dependent on cycle time) |
| Dust Control | Fully enclosed (Environmentally friendly) | Open (High dust emission) |
| Safety System | Integrated Intelligent Control/LMI | Manual Load Monitoring |
| Vessel Suitability | Up to 200,000 DWT | Standard Bulkers |
| Material Loss | Minimal (Closed loop) | High (Spillage during grab) |
Hangzhou Aotuo Mechanical and Electrical Co., Ltd. specializes in environmentally friendly and efficient equipment. Unlike open grab unloaders, AOTUO’s screw unloaders feature a fully enclosed conveying path. This design, combined with integrated dust collectors, prevents material spillage and airborne dust, meeting the strict environmental standards of international markets like Australia and Singapore.
Yes. Leveraging 20 years of R&D experience, Hangzhou Aotuo Mechanical and Electrical Co., Ltd. has developed high-end equipment capable of servicing ships up to 200,000 DWT. With an unloading capacity reaching 3000t/h, the systems are designed for high-efficiency port transfer, making AOTUO a key player in the "Belt and Road" strategy's global layout.
Hangzhou Aotuo Mechanical and Electrical Co., Ltd. is a national high-tech enterprise and the responsible drafting unit for the industry standard JC/T 2575 "Bulk Cement Spiral Unloader". With over 100 patents and software copyrights, AOTUO’s focus on industrial automation and intelligent control systems has set a benchmark for both domestic and international port equipment safety and performance.
