Hainan Nanshan Port Tire-Mounted Screw Unloader
01
Project Introduction
The equipment is equipped with a heavy-duty engineering tire chassis, and does not require tracks or concrete foundations.
During operation, the force is borne by hydraulic cylinders, ensuring safety and reliability.
It can freely move and position, and can be parked at the rear during non-operation periods, releasing the resources of the dock shoreline and improving the efficiency of vessel berthing and unberthing.
The fully enclosed spiral conveying system and negative pressure dust suppression system are in line with the high standards of ecological and environmental protection in Hainan.
The materials are conveyed throughout the process in a sealed manner, without any spillage or leakage, meeting the strict environmental protection requirements.

Equipment Introduction
The "ship - machine - vehicle" integrated direct loading and unloading mode eliminates the secondary transfer process of "ship → storage yard → vehicles", achieving seamless connection of loading and unloading, shortening the logistics chain by more than 30%, significantly reducing loading and unloading losses, and improving the shipping efficiency.
The rated processing capacity of the equipment in this project is 400 tons per hour, capable of continuous, uniform and stable operation, suitable for efficient unloading of bulk goods such as grains, fertilizers, and sulfur, supporting the stable production and supply of regional supply chains.

Outlook
As the cargo throughput of Hainan Free Trade Port continues to rise, the "dual carbon" goal is being deeply implemented in coastal ports.
The mobile tire unloading crane is expected to achieve large-scale replication in the Guangdong-Hong Kong-Macao Greater Bay Area, the Yangtze River Economic Belt, and the Beibu Gulf port cluster.
Its "non-occupying the shoreline" feature aligns with the modern port's high-density, multi-commodity, and strong environmental protection requirements, providing a low-cost and highly flexible upgrade path for the renovation of old docks.
Aotuo will promote this technology to rise from an "enterprise solution" to a "national standard", explore integration with new energy power systems, reduce the carbon footprint throughout the life cycle, and develop from a "single breakthrough in Zhejiang manufacturing" to a "systematic answer" supporting the high-quality development of Chinese ports.

Technical Highlights
1. All-wheeled mobile design, "zero constraints" on dock operations.
The equipment uses a heavy-duty engineering tire chassis, eliminating the need for tracks or fixed foundations. It can freely move and flexibly position itself on the dock surface, easily handling multi-berth operation needs, significantly improving equipment utilization, and truly achieving "one machine for multiple uses, available on call."
2. It does not occupy wharf shoreline resources, freeing up valuable operating space.
Breaking through the limitations of traditional fixed ship unloaders that "dominate" the front shoreline, the entire machine can be moved to the rear area when not in operation, without occupying valuable wharf shoreline operating space. This ensures efficient berthing and unberthing of large vessels while reserving ample space for general cargo or container operations, maximizing the utilization of shoreline resources.
3. Fully Enclosed Screw Conveyor + Negative Pressure Dust Collection: Protecting the Blue Skies and Seas.
In response to Hainan's stringent environmental protection requirements, the equipment integrates a fully enclosed screw conveyor system with fixed-point negative pressure dust collection. Materials are transported in a completely sealed manner from the ship's hold to the truck bed, preventing spillage and leakage. High-efficiency dust collectors are installed at key material drop points to suppress dust overflow at the source, contributing to the construction of a green port and enhancing Hainan's ecological environment.
4. Seamless direct loading and unloading eliminates intermediate transfer links.
An innovative integrated "ship-machine-truck" operation mode is adopted. After being lifted by a screw conveyor, materials can be directly loaded into trucks via a high-efficiency and environmentally friendly bulk loading machine, completely eliminating the traditional secondary transfer process of "ship → yard → vehicle". This significantly shortens the logistics chain, reduces loading and unloading losses, and significantly improves shipping efficiency.
5.400tph high-efficiency continuous operation, ensuring stable and guaranteed production capacity.
Optimized propeller blade structure, rated handling capacity reaches 400 tons/hour, enabling continuous, uniform, and stable unloading operations. Compared to intermittent grab unloading, efficiency is significantly improved, especially suitable for the rapid unloading of light bulk cargoes such as grain, fertilizer, and sulfur, injecting strong momentum into the project's stable production and supply.
