In May 2013, SBS was awarded the contract to upgrade the overstage machinery, which was then carried out in 2013 and 2014. The machinery of both side stages and the main backstage engines were initially upgraded. The main stage then followed in 2014, involving 60 mechanical hoists with a payload of 750 kg, 20 point hoists with a payload of 500 kg, and 4 heavy-duty point hosts with a payload of 2,000 kg. A total of 200 tonnes of steel were dismantled, and some 500 tonnes of new material fi tted. The wind and thunder machines were also upgraded/overhauled, and integrated into the COSTACOwin© stage controls together with the other 183 drive shafts.

In November 2014, the overstage machinery upgrade was completed and handed over to a satisfied customer.
