The four Liebherr cranes held the bridge sections for 22 hours whilst the two small machines took care of the installation of around 70 steel top and bottom chords for the side lattice components. The loads were then attached and the small cranes started installing the safety equipment under the new bridge structure. Peters was extremely satisfied once the job had been completed: “We arrived with our cranes on Friday evening, 22 hours later the bridge had been installed and the safety equipment under the skywalk was installed on Sunday evening. The whole job went like clockwork.”
In fact, not only did they adhere to the schedule, they actually completed the job slightly early. Around six hours before the road closures were ended, all the work by the Nolte team had been completed and the last Liebherr cranes were on their way back to the company’s yard in the north of the city.
