Lifting 125 meters long, 890 tons legs of Ain Dubai.
Mammoet has successfully completed its role in the construction of Ain Dubai, the world’s tallest observation wheel. Developed by Meraas, Ain Dubai sits on Bluewaters in the heart of Dubai and once operational, it will provide residents and visitors extensive views of the iconic city of Dubai and its shoreline.
In 2014 Hyundai Engineering & Construction (HDEC), the main contractor on the project, awarded Mammoet the heavy lifting contract to install the key structural elements of the wheel. Being involved in the early phase of the project enabled Mammoet to present an installation method that delivered greater efficiency, safety and cost-effectiveness. They proposed installing the largest elements, the legs and spindle, directly from the barge they arrived on onto foundations with two of their super heavy lift cranes. This eliminated the need for temporary storage, multiple barge transports and working at extreme heights.
“I have no doubt that Ain Dubai will earn its place among the world's most famous landmarks, setting a new precedent in the tourism industry and making Dubai a 'first choice' destination for the international leisure and business traveler. We are committed to supporting Dubai’s ambitions to strengthen its position as a global city and business hub of the Middle East,” said Michel Bunnik, Commercial Director of Mammoet Middle East and Africa.
Each 890-ton leg measured 125m long and 6.5m in diameter. They were rolled onto Mammoet’s barge using 40 axle lines of SPMT at the fabrication yard in Abu Dhabi. Once on the barge, the legs were securely floated to the site. For the installation, Mammoet paired the world’s biggest crane - PTC 200-DS - a 5000-ton ring crane, with a 3000-ton crawler crane. Together they ensured the stability and flexibility required to lift each leg and the spindle from the barge into position, whilst working 137m above the ground. Subsequently, Mammoet set a world record by lifting the 1,900-ton spindle to sit on top of the four legs: it was the heaviest and highest tandem lift ever undertaken worldwide.
