Core Engineering Breakthroughs

1. Dual-Girder Heavy-Lift System

• Box Girder Structure: S460ML steel (EN 10025)

  • Span: 40-200m | Height: 80m under hook

• Synchronized Dual Hoists:
  → ±1mm lifting coordination (Laser + CANopen)
  → 200-3,200T capacity range

2. Block Turnover Technology

• Multi-Axis Control:
  → Pitch/Roll/Yaw adjustment (±0.1°)
  → Auto-center of gravity calculation

• Anti-Sway System:
  → Predictive compensation for 100T+ sections
  → <0.5° oscillation at 20m/min

3. Corrosion-Resistant Construction

• Hot-dip galvanized steel and marine-grade epoxy coatings (ISO 12944 C5-M) withstand saltwater, humidity, and UV exposure.

• Sealed IP66-rated motors and electrical systems for harsh environments.

4. Advanced Automation

• PLC control with laser-guided positioning (±5mm accuracy) for alignment of ship blocks.

• IoT-enabled remote monitoring and predictive maintenance capabilities.

5. Customized Mobility

• Rail-mounted or rubber-tired configurations with 360° steering for dockyard flexibility.

• Optional self-propelled systems for repositioning across large shipyards.

6. Safety & Compliance

• Redundant braking systems, overload limiters, and storm-proof anchoring.

• Compliance with DNV GL, ABS, and Lloyd’s Register standards.
