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

### Q: What materials are used in trolley brake systems for optimal safety?
**A**: Our trolley brake systems use high-grade steel, cast iron, and specialized friction materials (organic/resin, semi-metallic, or ceramic) to ensure durability, heat resistance, and reliable stopping power in transport applications.

### Q: How does the actuation mechanism work in a trolley brake system?
**A**: The actuation mechanism (lever, pedal, or hydraulic cylinder) transfers force to the brake caliper, which clamps the brake pads against the disc (rotor), creating friction to decelerate or stop the trolley safely and efficiently.

### Q: Why is regular maintenance important for trolley brake systems?
**A**: Regular maintenance ensures brake pads, discs, and calipers remain in optimal condition, preventing wear-related failures and maintaining safety-critical performance in transport equipment manufacturing environments.
