Window Cleaning The World’s Tallest Building

Daring window washers clean world's tallest building.

Window-cleaning the world’s tallest building: Dubai, United Arab Emirates — It’s hard work cleaning the windows of the world’s tallest building, but somebody has to do it. The Burj Khalifa in Dubai is covered in 24,000 panes of glass. The workers who clean them start at the 160th floor and work their way down. That’s more than 2,700 feet. Before they start their work, they check and double-check their harnesses and ropes. They also measure wind speed because a gust of wind could be dangerous. It takes three months to clean every window, and then crews start all over again.

Meanwhile in China..

Climbing duo Vadim Makhorov and Vitaliy Raskalov scaled the 632 metre building without any ropes.

Shanghai Tower skywalkers climb second tallest building in world without safety equipment: Two Russian climbers filmed themselves defying gravity (and death) by climbing the world’s second tallest building without any ropes or climbing gear. Vadim Makhorov and Vitaliy Raskalov used head cameras to film themselves breaking into and climbing the still unfinished Shanghai Tower in China, as they scaled the 632m structure without any safety gear.

Their cameras show vertigo-inducing panoramas of Shanghai hundreds of metres below throughout their ascent. The pair even passed clouds on their journey to the top. The Tower will be one of the tallest buildings in the world upon its completion, second only to the 830 metre Burj Khalifa in the UAE, the tallest man-made structure in the world. When both climbers reach the top, their head-cams show them peering down into the abyss below. Makhorov told Yahoo! News: "We had to wait for hours for the clouds to part but it was well worth the wait, the view was like something from an aircraft window. "As soon as we saw a gap in the clouds were climbed right to the top of the crane and were able to get some great shots of the city below."

Don't look down! Vadim Makhorov sits in a cage above the Shanghai Tower, with the city sprawled more than 2,000 feet beneath him.

Vadim Makhorov and Vitaly Raskalov captured these shots from a height that would make most people sick.
