Double-girder Bridge Crane: the "three-dimensional transportation center" of industrial plants
In a century-long heavy-duty factory building, an orange-red double-girder bridge crane stretches across the sky like a giant steel arm. The arc of its hanging hook hides the core code of "ton-level lifting" in industrial production. It uses the mechanical advantages of its double-girder structure as a fulcrum to leverage the full range of lifting scenarios, from metallurgical steel coils to shipbuilding sections, becoming a key hub that connects the factory building's "vertical space" and "production rhythm."
Technical Parameters:
| Lifting Capacity | 50-150 t → Metallurgical workshops (steel coil and roll handling); 200-300 t → Heavy industry (molds and large equipment lifting); 500 t+ → Nuclear power and shipbuilding (reactor pressure vessels and shipboard section lifting) |
| Span | 10 m～35 m (mainstream), up to 40m+ in special scenarios (such as shipyard) |
| Lifting Height | 6 m～30 m (conventional), low clearance models can be compressed to 4 m (suitable for renovation of old factories) |
| Lifting Speed | Low speed: 0.5m/min to 2m/min (mold alignment, precision equipment maintenance, error ≤ 5mm); High speed: 8m/min to 10m/min (bulk material rapid transfer, such as steel coil transfer) |
Breakthrough Scenarios: "Invisible Transportation Capacity" at the Heart of Industry
→ Metallurgical Workshop: "Aerial Assembly Line" for Steel Coils
A double-girder bridge crane combined with electromagnetic suction cups/vertical coil clamps automates the entire process from "steel coil lifting → rolling → stacking," completing 15+ cycles per hour and supporting a "10,000-ton daily" metallurgical production capacity.
→ Shipbuilding and Heavy Industry: "Vertical Jigsaw Puzzlers" of Giants
When lifting 1,000-ton ship sections, a customized balance beam combined with micro-speed control achieves millimeter-level positioning, making dock assembly like "playing with building blocks in the air" and shortening construction time by 40%.
→ Special Fields: "Customized Solutions" for Extreme Scenarios
Nuclear Power Plant: HAF-certified models meet "oil-free lubrication and low dust emissions," ensuring "zero vibration and zero pollution" when lifting nuclear fuel assemblies.
Chemical Plant: Explosion-proof modifications comply with GB 3836, with fully enclosed motors and electrical appliances, ensuring safe operation in flammable and explosive areas.
