Spider, a division of SafeWorks, LLC, recently provided the suspended scaffolding solution for maintenance on a wooden suspension bridge that spans the south fork of the American River in Placerville, California.
Spider has completed the final stages of powered access work on the Burlington Bristol Bridge in Philadelphia, PA. The truss bridge was in dire need of renovations. The latest inspection revealed extensive wear on all components of the trolley system, some of which dated back to the bridge’s original 1931 completion date. On site renovations took place nearly 130 feet above the roadway (200 feet above the river) with minimal existing walkways to access the work points. The ST-17 Air Spider was the perfect solution, allowing access throughout the project and requiring only a single rigging point. The scaffold system itself involved the attachment of a series of needle beams, fall protection, and a scaffold hand controlled system at the tower’s top level. By adding flydecks, the crew was able to work the full width of the job without having to reposition the Spider basket, saving valuable time.
