Purpose: Designed for steel strands (such as high-strength steel strands in bridges, slope support and other projects) to pass through the reserved channels, replacing manual threading, improving efficiency and reducing labor intensity.
Core structure:
- Power system: motor drive, providing traction (common power 5.5-15kW).
- Conveying device: multiple sets of rollers or clips, clamping and pushing the steel strands through friction.
- Guide mechanism: ensure that the steel strands enter the channel smoothly and reduce jamming.
Features:
- High efficiency: The threading speed can reach 5-15 meters per minute, which is suitable for long-distance threading (such as channels over 100 meters).
- Strong adaptability: The roller spacing can be adjusted to adapt to steel strands of different diameters (common Φ12-Φ15.2mm).
- Portable: Some models are detachable for easy movement on site.
