Among the technical highlights of U2’s current 360 degrees world tour is an enormous transforming video screen that hangs from an equally impressive claw structure above the stage.
Comprising 888 hexagonal panels that support 500,000 Barco LED pixels, the screen weighs 52-tonnes including its supporting trussing.
The mammoth size of the screen made production work difficult for Kinesys, which was tasked with implementing its automation and motion control systems.
“This was the heaviest, most complex and interconnected system we have undertaken to date, with 48 motors following unique motion profiles to allow the deployment of over 52 tonnes of video screen,” commented Kinesys’ Dave Weatherhead.
The entire structure has the ability to stretch from its seven-metre compressed height to more than 22m at full extension forming a conical shape as it expands.
Forty Kinesys Evo zero speed two-tonne and one-tonne chain hoists are connected to the screen structure at equal intervals. Four different heights along with eight custom built winches are controlled by the company’s K2 3D software control package to achieve the transformation effect.
