Inner-suspended lattice gin poles are specialized lifting devices used in the construction of high-voltage transmission towers. These engineered structures provide a safe and efficient method for assembling lattice steel towers piece by piece, significantly accelerating project timelines compared to traditional crane-based methods.
Designed for vertical lifting operations, these gin poles suspend within the tower structure during assembly, offering precise control over heavy component placement. Their modular design allows adaptation to various tower configurations, making them indispensable for power infrastructure projects in challenging terrains.
For construction firms and utility companies seeking optimized tower erection solutions, our range of inner-suspended gin poles delivers reliable performance across diverse project requirements. Discover how this technology can transform your transmission line construction methodology.
