Double-girder Bridge Crane: the "heavy lifting hub" of industrial workshops
In the steel jungle-like industrial workshop, dozens of tons of steel coils are transported across regions, giant molds are precisely positioned, heavy equipment is inspected and lifted... Behind every "light lift", it is inseparable from the support of the "steel backbone" of the double-girder bridge crane - with its core advantages of "double-girder load-bearing capacity + precise controllability", it defines the efficiency and safety boundaries of heavy lifting.
Technical Parameters:
| Lifting Capacity | 50 t～500 t (conventional), customized capacity can exceed 1000t+ (such as lifting of nuclear power pressure vessels) |
| Span | 10 m~35 m (mainstream), up to 40m+ in special scenarios |
| Lifting Height | 6 m～30 m (conventional), low clearance type 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 Applications: Covering All Fields from Metallurgy to Nuclear Power
→ Metallurgical Workshop: "Aerial Assembly Line" for Steel Coils
A double-girder bridge crane combined with electromagnetic suction cups/coil clamps automates the entire process: "steel coil lifting → rolling line connection → finished product stacking." In line with the production line's pace, it can complete 15+ lifting cycles per hour, supporting the rolling mill's "10,000-ton daily output."
→ Heavy Machinery: "Precision Movers" for Molds and Equipment
Equipped with customized lifting equipment (such as balance beams and vacuum suction cups), it achieves "millimeter-level positioning" when lifting 100-ton marine propellers and 10,000-ton press molds through "slow-speed lifting and simultaneous fine-tuning," preventing scratches on delicate surfaces. → Special Scenarios: Customized "Extreme Challenges"
Explosion-proof Retrofit: Chemical and oil and gas workshops utilize explosion-proof motors and insulation treatment to meet Ex IIB T4 explosion-proof ratings.
Corrosion Protection Enhancement: Marine engineering workshops utilize fluorocarbon spray coating and cathodic protection to withstand salt spray corrosion and extend service life by 50%.
Nuclear Power Adaptation: HAF safety certification achieved, ensuring ultimate safety with zero vibration and dust during the lifting of nuclear fuel assemblies.
