- **Caution**: 
- **Caution**: 

### Q: What are the primary applications of a floating crane?
**A**: Floating cranes are used for heavy lifting in port operations (loading/unloading ships), offshore construction (platform installation), and marine salvage operations due to their mobility and high lifting capacity.

### Q: What materials ensure durability in floating cranes?
**A**: Floating cranes are constructed with high-strength steel for structural integrity and marine-grade aluminum alloys for corrosion resistance in harsh marine environments.

### Q: How does the dynamic positioning system benefit floating crane operations?
**A**: The dynamic positioning system maintains the crane's position automatically using thrusters, enabling precise operations in challenging conditions like strong currents or winds without anchoring.
