04/12/2014 Four Liebherr tower cranes building the tallest building in the world in Jeddah, Saudi Arabia
The very first building over 1,000 metres in height – the Kingdom Tower in Jeddah, Saudi Arabia. Liebherr was awarded the order to supply four HC-L series tower cranes for the project. Current plans call for three 280 HC-L luffing jib cranes and one 357 HC-L model to be used. The experts at Liebherr Tower Crane Solutions are providing support to the contractor to ensure economical crane planning.
Three Liebherr 280 HC L luffing jib cranes will build the side wings of the Kingdom Tower. These cranes will be anchored on the outside of the building and will reach hook heights of approx. 400 m. The Liebherr 357 HC-L luffing jib crane will place the top on the building at a height of around 1000 m. To get to this height it will first have to climb up into the air by itself in the central building
To reach these enormous heights the cranes will have to move upwards in several climbing stages. For this purpose they will be positioned on the sky terrace of the building or on various cantilever platforms mounted on the outside of the building. The tower cranes on the Kingdom Tower site will erect and dismantle each other.
