Double Girder Bridge Crane for Heavy Industry Plant
Double-beam bridge cranes (double-beam bridge cranes) are based on a "double main beam + rigid support" structure and are designed for heavy industry with high loads, large spans, and frequent operations. They are commonly found in steel metallurgy, heavy machinery manufacturing, ports, and docks.
Key technical parameters (typical configuration for heavy industry):
| Parameter Type | General Configuration | Override special configuration |
| Lifting capacity | 20-100 tons | 150-500 tons (Metallurgy) |
| span | 16-31.5 m | 35-40 m (Deflection needs to be verified) |
| Work Level | A6-A7 (Intermediate - Heavy) | A8 (Extra heavy grade, for metallurgy) |
| Lifting height | 10-20 m | 25-35 m( Blast furnace maintenance scene) |
| Running speed | Large trolley 45m/min, small trolley 20m/min | Frequency conversion speed regulation (0-80m/min stepless) |
Typical operations include:
• Steel mills: lifting ladles (load 20-100 tons), billet stacking;
• Shipyards: lifting hull sections (single piece weight 50-200 tons);
• Mining equipment factories: handling large crusher components (span 25-35 meters).
