In Novi Sad, Serbia, a Potain MCT 88 tower crane is playing a pivotal role in a project to rehabilitate the Žeželj Bridge, which spans the Danube River and connects a key stretch of international railway. Azvi, the construction division of Seville, Spain-based Azvi Group, was tasked in August of 2016 with rebuilding the bridge which was damaged in war. In order to access the lifts, the company needed a lifting solution that would enable operators to remotely control a crane, as it would be erected on a cofferdam in the middle of the Danube River and difficult to physically access. Azvi chose a Potain MCT 88 for the project because of its robust remote control functions and easy erection.
“For this specific job, one of the most satisfying features of this crane was its radio remote control function,” said José Ramón Contreras, deputy project manager for Azvi. “The crane’s location on the river is a little precarious, so ensuring that our contractors can make successful lifts from a remote location has given us a big boost in efficiency. The minimal components also helped us to get to work quicker than we might have with other tower cranes.”
The 5 t (5.5 USt) MCT 88—the largest in Potain’s MCT city topless series—is currently erected with 52 m (171 ft) of jib in the middle of the Danube River, on top of a customized cofferdam. River water must be continually pumped away from the cofferdam to ensure site stability. Azvi assembles metallic arches for the bridge on the riverbank and moves them by pontoon to the crane’s position in the middle of the river. The MCT 88 then lifts the arch components, which weigh nearly 5,200 t (5,732 USt) when combined, on top of the original Žeželj Bridge’s foundations. Work on the bridge is expected to continue into 2017.
