The QD Overhead Crane is a heavy-duty double girder bridge crane designed for demanding industrial environments requiring high lifting capacities, frequent operation, and reliable performance. Below is a detailed breakdown of its features, specifications, and applications based on the search results:
Heavy-Duty Design:
Built for A5–A8 work duty classes (ISO 4301-1), suitable for extreme workloads and frequent use.
Box welded girders (Q235B/Q345B steel) ensure durability and stability.
High Lifting Capacity:
5–550 tons, with dual-hook configurations (e.g., 16/3.2t, 200/50t, 550/250t).
Customization:
Adjustable spans (10.5–40.5 meters), lifting heights (6–60 meters), and speeds.
Optional variable frequency drives (VFDs) for smooth acceleration and energy efficiency.
Safety & Control:
Overload protection, anti-collision systems, and emergency stops.
Operated via cabin, remote, or ground control.
| Parameter | Range/Details |
|---|---|

Steel Mills: Handling molten metal, coils, and heavy machinery.
Ports & Shipyards: Loading/unloading containers and ship components.
Power Plants: Maintenance of turbines and generators.
Mining & Construction: Transporting raw materials and equipment.
Warehousing: Heavy-duty logistics in large storage facilities.
Durability: Robust construction withstands harsh environments (dust, humidity, high temperatures).
Precision Control: Winch trolley mechanism ensures accurate load positioning.
Cost Efficiency: Reduced maintenance and energy consumption compared to traditional cranes.
Flexibility: Configurable with specialized attachments (e.g., grabs, magnets).
The QD Overhead Crane is engineered for industries requiring high-frequency, heavy-capacity lifting in challenging environments. Its combination of durability, precision, and adaptability makes it ideal for steel mills, ports, and power plants. For lighter applications, LH cranes offer a more economical alternative.
