Robert, who sometimes wears a Spider-Man costume during his climbs, usually works without a safety harness, relying on bare hands and sturdy footing.But organisers of the Dubai climb insisted he wear a rope and harness this time.The tower has 160 habitable storeys with an observation deck located on the 124th floor and as expected it took Robert about six hours to get to the top.An ambulance, with a stretcher was parked alongside other emergency vehicles at the base but they weren't necessary as Robert successfully navigated the tapered spire that extends beyond the top floors of the Dubai structure.Robert has climbed more than 70 skyscrapers, including the Empire State Building, Chicago's Willis Tower and the Petronas Towers in Kuala Lumpur. In 2004 he conquered Taiwan's Taipei 101, which, before the Burj opened in January last year, was the world's tallest building.
