Custom Telescopic Platforms Provide Access to Bridge Cable-Stays

摘要

Delaware's Indian River Inlet Bridge Project is a $150-million design-build construction by Skanska USA of a three-span cable-stayed bridge (400 ft, 950 ft, 400 ft) with flanking approach spans and a pedestrian walkway. It is built to withstand a Category 5 hurricane. The cable-stayed superstructure consists of cast-in-place (CIP) concrete edge girders, with both precast and CIP concrete transverse floor beams, and a CIP concrete deck. With the goal of providing Skanska a platform to meet the best possible design for maximized safety and efficiency, Klimer developed and created a custom platform for Skanska's stay cable installation crew with custom telescopic platforms. Selecting the KlimerLite mast-climbing work platform and designing custom 9-ft translating extensions allowed access to both sides of the cable stays. Maximum efficiency was achieved by having access to both sides of the cable stay, which eliminated the requirement for a second platform.
