## 5. Engineering Risks & FAQ
- **Caution**: 
- **Caution**: 
- **Caution**: 

### Q: What materials are typically used in runway systems for bridge cranes?
**A**: Runway systems are primarily constructed from structural steel grades like S355JR or carbon steel, chosen for their strength, durability, and load-bearing capacity in industrial environments.

### Q: What are the key components of a runway system?
**A**: A complete runway system includes the runway beam (supporting structure), runway rail/beam (travel path), rail clips/fasteners for secure attachment, and bumpers/end stops for safety at track limits.

### Q: How does a runway system support bridge crane operation?
**A**: The runway system provides the structural framework and precise travel path for the bridge crane's end trucks, ensuring smooth, stable movement and proper load distribution across the crane span.
