- **Caution**: 

### Q: What weight capacity do carrier trolleys typically handle?
**A**: Carrier trolleys are designed for various capacities, typically ranging from 500 lbs to 10,000+ lbs depending on wheel assembly and frame specifications. Consult manufacturer ratings for specific load requirements.

### Q: How do polymer bearings improve trolley performance?
**A**: Polymer bearings reduce friction, require minimal lubrication, resist corrosion, and operate quietly compared to traditional metal bearings, extending service life in industrial environments.

### Q: What maintenance is required for overhead conveyor trolleys?
**A**: Regular inspection of wheels, bearings, and attachment hooks is essential. Lubricate according to manufacturer guidelines, check for wear on tracks, and ensure proper alignment to prevent premature failure.
