Double-girder Semi-gantry Crane: 16-ton heavy load "single-side breakthrough", safety production is embedded in the bones and blood
Inside the factory, a blue double-girder semi-gantry crane with a "double-girder rigidity + single-sided outrigger" configuration lifts 16 tons of weight and operates smoothly. The "Safety Production Lifting Limit 16t / Limit 8t" sign on the main beam is not only a warning but also a safety closed loop from structure to control, providing a "space-saving + load-bearing" dual-optimal solution for heavy steel handling and equipment lifting.
Technical Parameters:
| Lifting Capacity | Master hook: 16 tons, Auxiliary hook: 8 tons |
| Span | 12~35 m |
| Cantilever Length | 5~18 m |
| Lifting Height | 6~24 m |
| Lifting Speed | Hoisting speed: 8~18m/min (dual speed: 18/3m/min) |
Double-beam structure: A rock-solid "steel backbone" for heavy loads.
✅ Double-box main beam: Welded from Q355B low-alloy manganese steel, it boasts 30% higher torsional rigidity than a single beam. Static deflection at mid-span is ≤ L/1000 (L is the main beam span), allowing for smooth lifting of a 16-ton full-load.
✅ Single-side outrigger philosophy: One side runs along the track, while the other "hangs" on a factory column or wall. This eliminates the cost of half a track, eliminates structural changes in existing plant renovations, and allows for rapid deployment in 30 days.
✅ Dual hooks for flexible switching: The 16-ton main hook handles heavy loads (such as steel coils and molds), while the 8-ton auxiliary hook is suitable for delicate lifting (such as accessories and tools). This "one machine supports two" system, increasing operational efficiency by 40%.
Suitable for all scenarios:
Outdoor cargo yards: Lifting steel and containers, with double beams capable of withstanding 16-ton impacts;
Workshop extensions: Extending the cantilever deep into the factory floor, connecting to production lines, and handling heavy equipment;
Specialized customization: The metallurgical version is heat-resistant to 600°C (with a heat shield), and the explosion-proof version is suitable for advanced work areas (Exd IIB T4 certified).
