Questions & Answers

Q: How tall is Iron Dubai compared to other observation wheels?

Iron Dubai stands at over 250 meters tall, making it the world's tallest observation wheel, surpassing its predecessor by 82 meters.

Q: How was Iron Dubai able to achieve such height on reclaimed land?

Iron Dubai's foundation piles extend 5 meters into solid bedrock, bypassing the reclaimed land. The reclaimed land only provides lateral support for the structure.

Q: What were the major challenges faced in building Iron Dubai?

The major challenges included keeping the legs standing at a precise angle while fitting the hub and spindle, creating a self-supporting structure, and constructing a temporary support system.

Q: What is the driving mechanism of Iron Dubai?

Iron Dubai's driving mechanism consists of 64 tires positioned against the rim, which slowly rotate and push the wheel around using friction, resulting in one revolution every 38 minutes.

Summary & Key Takeaways

• The London Eye, originally intended to be temporary, became a permanent fixture and sparked the construction of 18 more giant observation wheels worldwide.

• Iron Dubai is the world's tallest and largest observation wheel, standing at over 250 meters tall and surpassing the height of its predecessor by 82 meters.

• Constructing Iron Dubai involved overcoming structural challenges, such as achieving self-support and building on reclaimed land.
