The next tallest building, Kingdom Tower, in Jeddah, has employed the services of the world’s tallest construction crane.

Construction of the skyscraper, which will stretch to a height of more than a kilometre, is being assisted by custom-built cranes from Germany’s Liebherr & WolffKran.

Known as “climbing cranes”, the lifting devices are designed to accompany the Tower’s growth both externally and internally, in the latter case utilizing any of the building’s 65 interior elevator shafts to make the climb.

“Now that we have completed our subterranean work, we are airborne,” said Mounib Hammoud, CEO of Jeddah Economic Company in the Saudi Gazette. “The unprecedented size and height of Kingdom Tower means we can only utilise the very best in equipment, material and methods. Liebherr’s and WolffKran very impressive and innovative cranes fit this bill.”

The largest of the six cranes, Liebherr type 357 HC-L, can lift up to 18 tons at a speed of 44 meters / minute with heights to parallel that of the tower . The cranes are attached to the body of the building but sits atop a phenomenally narrow tower support of only 2.4 meters X 2.45 meters.

With the tower’s foundation now in place, vertical, above-ground construction commenced in September. Plans call for the first ten floors to be completed by the end of the year.

The Kingdom Tower features 170 stories, seven stories of which will be allocated for the five-star Four Seasons Hotel offering 200 rooms and121 luxury serviced apartments, and seven stories for offices. The Tower will also have 61 stories that include 318 housing units of various types amenities, gyms, spas, cafes and restaurants, two sky lobbies and world’s highest observation decks, located 644m high.
