APPLICATION SCENARIO

Grab Double Girder Overhead Crane – For Bulk Material Handling Across All Industries

The QZ Grab Double Girder Overhead Crane is designed to handle bulk materials like coal, ore, slag, sand, and construction waste. It uses a four-rope grab bucket and heavy-duty dual girders for stable, high-capacity lifting. The system supports both cabin operation and remote control. Suitable for indoor and outdoor use, even in hot, humid, and dusty conditions.

Main Applications

1. Steel and Metallurgy

Scrap Metal: Quickly lifts scrap steel, iron, and recycled metals.
Blast Furnace Feeding: Moves coal, coke, and ore for steel production.
Slag Removal: Clears molten slag after processing.

🛠 Used in Guangxi Yiji Steel's 10-million-ton green冶金基地 for clean, automated upgrading.

2. Port Operations & Terminals

Coal & Grain: Loads and unloads coal, wheat, soybeans from ships or trucks.
Construction Materials: Transfers sand, gravel, and minerals at docks.

🔧 In busy ports, the crane adjusts position based on ship size. The grab moves along the bridge and drops into cargo holds. Multiple cranes can be scheduled via port systems for faster operation.

3. Waste Management & Recycling

MSW Handling: Grabs household waste at waste-to-energy plants.
Recyclables: Sorts metal, plastic, and paper in recycling facilities.

4. Mining & Quarrying

Ore Transport: Picks up limestone, iron ore, bauxite at open-pit and underground mines.
Coal Stockpiles: Moves coal to crushers or storage yards.

💡 During mining, the crane shifts materials between workshops, reducing downtime.

5. Energy & Petrochemicals

Bulk Chemicals: Lifts sulfur, petroleum coke, fertilizers in plants.
Biomass Fuels: Transfers wood chips, pellets in power stations.

6. Construction & Cement

Cement, Clinker: Moves raw materials in cement plants.
Debris Removal: Clears demolition waste like bricks and concrete blocks.

🚧 On construction sites, it feeds sand to mixers or lifts rubble into trucks—safer and faster than manual work.
