Dubai Arena’s roof built with Demag construction cranes
Aljaber Heavy Lift operated the CC 8800-1 cranes that built the roof’s mega-trusses
Details have been revealed of the mammoth cranes used for the mega-trusses of Dubai Arena, an under-construction entertainment destination that developer Meraas recently said is on track to open in 2019.
The roof of Dubai Arena – which at almost 4,000 tonnes (t) matches the weight of seven Airbus A380 aircraft – is supported by two 120m “mega-trusses” that span the length of the facility. Earlier this week, Meraas said that some of the world’s biggest cranes, with a capacity of 1,600t, was used for the mega-trusses.
Two models of the Demag CC 8800-1 crane were used for the operation, Construction Week has learned. The crawler crane, according to Demag’s website, has a lifting capacity of 1,600t and “a maximum load moment of 26,160 tonne-meters”. Aljaber Heavy Lift operated the cranes for the job.
Additionally, the developer also said that Assent, the structural steel company of UAE construction heavyweight ASGC, engineered the mega-trusses. This was done “under the supervision of Dar Al Handasah”, Meraas added.
Dubai Arena is one of the city’s most awaited developments. In an update released by Meraas earlier this week, the developer said that the construction and lifting of the mega-trusses was “considered among the most challenging processes” related to the project. Each mega-truss used for the roof of Dubai Arena is made up of 14 frames that were connected with 16,000 bolts.
ASGC, predominant in the market for its civil contracting work, is also helping to build the project, which has achieved major milestones such as the completion of its concrete, structural, and block works. “Finishing touches” are being added to the hospitality suites at Dubai Arena, and the City Walk structure is expected to seat up to 17,000 spectators when it opens in 2019.
Development progress has also been made in terms of in-building mobility, with Dubai Arena’s lifts and escalators now installed. Electrical and mechanical work is progressing to plan, and Empower is set to start tunnelling work as part of its agreement to provide 3,600t of chilled water to the building. Dubai Electricity and Water Authority is also supplying power to the building, and the installation of the arena’s rigging equipment, scoreboards, lighting, and sound systems is also imminent.
American equipment manufacturer Terex acquired Demag Mobile Cranes, a manufacturer of telescoping and lattice boom cranes in 2002. Demag was fully integrated as a fifth segment within Terex Corporation after a domination and profit and loss agreement between Terex and Demag took effect in April 2012.
