Spider, a division of SafeWorks, LLC, provided a fall protection solution for recent work on the O'hare Automated Transit System Bridge over I-90 in Chicago. According to a press release, the systems are capable of protecting as many as 40 workers at a time.
According to a press release:
Rossi Contractors, Inc. along with several subcontractors required complete fall protection while widening the span of the bridge. Spider provided 600 feet of SpiderLine temporary horizontal lifeline systems, 300 feet on each side of the structure. In order to allow the simultaneous installation of track ties, running, power and control rails, Spider engineered custom brackets that positioned the independent systems away from the base and provided unobstructed space for the installation of the track components. Additionally, the standard passthrough feature of the SpiderLine™ stanchions enabled the workers to move freely about their workspace without disconnecting from the system or using Y-lanyards.
