Meraas has announced the successful installation of the fifth of eight 107-metre sections of wheel rim of the Ain Dubai, the world’s largest observation wheel.
The wheel rim is now visible at Bluewaters, where the landmark is being assembled. At over 210 metres tall, Ain Dubai will eclipse the 167-metre High Roller in Las Vegas and the 190-metre New York Wheel planned for Staten Island. The hub and spindle at Ain Dubai were set in place last year and the final structure will include around 9,000 tonnes of steel, almost 25% more than the amount of iron used to construct the Eiffel Tower.
The wheel rim sections are connected to the hub and spindle by a total of 192 heavy-duty cables, each of which is comprised of over a hundred separate wires that are pre-tensioned with up to 300 tonnes of force. These cables will eventually support the combined 7,500 tonne weight of the rim and its capsules.
Abdulla Al Habbai, group chairman at Meraas, led a delegation to Switzerland, where Ain Dubai’s 48 passenger capsules are being manufactured by Swiss Rides on behalf of the project’s main contractor, Hyundai. The 30-square-metre double-glazed capsules are designed to accommodate 40 passengers and are expected to be installed in 2018.
Abdulla Al Habbai, group chairman at Meraas, said: “Ain Dubai reflects our ambition of creating new destinations that contribute to His Highness Sheikh Mohammed bin Rashid Al Maktoum, vice president and prime minister of UAE and Ruler of Dubai, vision of a city where people are encouraged to create, explore and enjoy.
“The destination is designed to bring people together from around the world and will enhance Dubai’s reputation as a leading choice for business and leisure travellers. It also embodies the pioneering and innovative nature of a city that has pushed the boundaries of modern engineering.”
Omar Delawar, chief projects officer at Meraas, said: “The assembly of the rim at Bluewaters is one of the most exciting phases in the construction of Ain Dubai, as it marks the arrival of the centrepiece of the island and another addition to Dubai’s impressive skyline – one that creates a new meeting point for the city and economy, as well as an open place for people to share many new experiences together”.
“With the first five sections of the wheel rim already connected to the hub, two winch devices have been fitted to rotate the wheel in a way that will allow Ain Dubai to receive the sixth, and subsequent sections of the wheel rim. Each rim section weighs roughly the same as two Airbus A380 aircraft and must be rested on five temporary support structures connected to the hub, as well as two 115-metre spokes”.
