  • Requires less headroom (minimum 6m clearance)
  • Faster installation time (2-3 weeks typical)
• Ideal For:
  • Small component handling
  • Maintenance workshops
  • Light-duty material transfer

Double Girder Overhead Cranes

• Capacity Range: 5-100+ tons
• Span Limit: Up to 50m
• Advantages:
  • Superior hook height (additional 1-1.5m)
  • Higher positioning accuracy (±3mm)
  • Greater durability for continuous operation
• Ideal For:
  • Heavy plate handling
  • Hull section assembly
  • Engine module installation
