- **Caution**: 

### Q: What is the primary function of a climbing frame in tower crane operations?
**A**: A climbing frame enables the vertical climbing movement of a tower crane during construction, allowing the crane to ascend as building height increases while maintaining structural stability and safety.

### Q: What materials are used in climbing frame construction?
**A**: Climbing frames are typically constructed from structural steel for the main framework, high-strength bolts for secure connections, and hydraulic components for controlled vertical movement.

### Q: How does the hydraulic climbing system work in a climbing frame?
**A**: Hydraulic climbing cylinders provide controlled force to lift the tower crane sections vertically along guide rails, while the control system manages pressure and movement for precise, safe climbing operations.
