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

### Q: What materials are available for mast bases in transport equipment manufacturing?
**A**: Our mast bases are manufactured in carbon steel for maximum strength, stainless steel for corrosion resistance, and aluminum alloy for lightweight applications.

### Q: How does the mast base ensure secure mounting and load transfer?
**A**: The mast base features a reinforced base plate with strategically placed stiffeners and gussets that distribute loads evenly, while leveling pads and mounting holes provide precise alignment and secure attachment.

### Q: What components are included in a standard mast base assembly?
**A**: A complete mast base assembly includes the base plate, leveling pads or shims for adjustment, pre-drilled mounting holes for secure fastening, and stiffeners or gussets for structural reinforcement.

## 6. Manufacturing Compliance
- ISO 898-1:2013 (MECHANICAL PROPERTIES OF FASTENERS)
