Sarens performs tandem lift at the Al Bayt Stadium in Quatar

To be able to assemble the retractable roof of the Al Bayt football stadium in Quatar, Sarens, on behalf of the Italian construction company CIMOLAI, performed the lifting of this various elements using two crawler cranes.

The two machines were a Demag CC6800 crawler crane rigged in SWSL 78/84 configuration with 450t of superlift and 96m radius with a total load of 95t. The second cane was a Liebherr LR1750 rigged in SWSL 84/91 with 400t of superlift and 102m radius. Its total load was 29t.


This tandem lift had to be planned down to the smallest detail to take into account the pick-up position and travelling distance the cranes had to cover before drop-off. While the customer had planned to use three cranes to perform the lift, only two cranes were needed for the operation. It took Sarens two months to complete all the work on this site.
