Segmental Bridge Lift at its facility in Arkansas. Its team worked hand in hand on-site personnel during the planning and engineering phases. “Once onsite, that cooperation continued,” said Cox. “We worked very closely with the bridge developers, construction teams and contractors during execution of the project. We were especially cognitive of safety, as that’s of paramount importance whenever lifting anything so massive.” The company’s engineers and equipment technicians were onsite at the bridge for about a month, which included set-up and teardown of the lift system. Active lifting took approximately 16 days. The bridge opened on December 23, 2020. “Working on the Cline Avenue Bridge allowed us to apply our special- ized lift expertise to a project that will have a significant, positive impact on the economic development of Northwest Indiana,” added Cox. “The new bridge will be a lifeline to nearby Chicago and beyond for commer- cial and industrial businesses along Indiana’s Lake Michigan shoreline.” The Cantilever Segmental Bridge Lift system can be customized for bridge projects of any size in North and South America. In addition, Engineered Rigging has an array of heavy lifting equipment available for rental and sale, including the powerful and compact strand jacks.

“This weatherproofing allowed us to meet our schedule of installing at least one segment per day.” To reduce costs, the customer asked that Engineered Rigging use the steel beams that it had already purchased to construct the lift. To ac- commodate that request, Engineered Rigging carefully inventoried and accurately modeled the materials on hand. The lift’s design comprised approximately 50 percent existing material and 50 percent new. Using the existing beam inventory caused additional issues. The Can- tilever Segmental Bridge Lift needed to weigh less than 75,000 lbs., otherwise the pier and cantilevered segments would not be able to sup- port it during erection. “Some of the existing beams were oversized and added unnecessary dead weight,” noted Cox. “To solve this issue, we optimized all new fabrica- tions to minimize weight and counter the heavier, oversized components.” Custom Design and Fabrication Engineered Rigging provided engineering design, fabrication, heavy lifting equipment rentals and onsite technical support for this complex project. It spent 12 weeks designing and fabricating the Cantilever Engineered Rigging’s Cantilever Segmental Bridge Lift hoists a 75-ton concrete bridge section into position. Total lifting time is 2 hours.
