The QN Type Double Girder Crane with Hook is a versatile, heavy‑duty overhead crane designed for general material handling in industrial environments where high lifting capacity, wide span, and operational reliability are required. The “QN” designation typically indicates a standard double girder bridge crane equipped with a hook – the most common configuration for workshops, warehouses, power plants, and manufacturing facilities. Unlike specialized cranes (e.g., magnet, grab, or ladle cranes), the QN crane uses a simple hook attachment, making it suitable for a vast range of loads – from individual machinery parts and pallets to large assemblies and containers.

1. General Manufacturing & Fabrication Shops Raw Material Handling: Lifting steel plates, bars, tubes, and sheets from storage racks to saws, shears, and presses. Work‑in‑Process Movement: Transporting partially assembled components (welded frames, machined parts) between workstations. Machine Tending: Loading and unloading heavy workpieces onto CNC machines, lathes, milling machines, and planers.

2. Warehousing & Distribution Centers Palletized Goods Storage: Lifting heavy pallets (e.g., industrial supplies, machinery parts, bulk bags) from floor to racking and vice versa. Heavy Item Retrieval: Moving oversized or overweight items (appliances, furniture, equipment) that exceed forklift capacity. Cross‑Docking Support: Transferring goods between receiving and shipping docks using overhead coverage.

3. Automotive Manufacturing & Assembly Press Shop: Lifting and feeding steel coils to uncoilers; handling stamping dies for changeovers. Body Shop: Transporting vehicle body shells, chassis frames, and subassemblies through welding and assembly lines. Powertrain Assembly: Lifting engine blocks, transmission housings, and axle assemblies with precise positioning.

4. Power Generation & Utilities Turbine Maintenance: Lifting gas turbine casings, steam turbine rotors, and generator stators during overhaul. Transformer Handling: Moving heavy power transformers (20‑100 tons) for installation, repair, or replacement. Pump & Valve Servicing: Lifting large pumps, valves, and motors in power plant workshops.

5. Heavy Equipment Manufacturing (Mining, Construction) Excavator Assembly: Lifting excavator bodies, booms, buckets, and track frames through assembly lines. Haul Truck Component Handling: Moving dump truck frames, powertrains, and suspension systems (20‑50 tons). Crusher & Mill Assembly: Handling large crusher frames, grinding mill shells, and trunnion assemblies.

6. Steel Service Centers (General Handling) Plate & Sheet Lifting: Using the hook with slings or lifting beams to handle steel plates (not requiring magnet). Structural Steel Movement: Transporting beams, channels, angles, and tubes through cutting, welding, and fabrication. Pipe & Tube Handling: Lifting bundles of pipes or individual large‑diameter pipes for processing.
