Argentina’s largest crane assists coke project

ALE has completed the lift of three coke drums at a Buenos Aires refinery, using what is said to be the largest crane in Argentina.

The Argentina branch of ALE completed the project, which involved the transport and lift of the three 435t, 42m-long drums, using a 1,350t Liebherr LR11350 crane.

The job was undertaken as part of YPF’s Nuevo Coke A project, and also involved weighing, transporting and lifting derricks and coke drum structures, as well as transporting and installing columns and heavy components.

ALE’s project manager Hernán Asensio said: “We faced several challenges; working to install such large, heavy coke drums in a small working area filled with obstacles such as trees and buildings. Because of the client’s schedule, the heaviest pieces needed to be lifted during the windy season, which posed another challenge.

“By using the LR11350 crane with P boom and four configurations, we were able to optimise the manoeuvres in the limited space we had available and minimise the removal of any obstacles.”

Liebherr supplies tower cranes to Kingdom Tower

Liebherr has won the contract to supply four HC-L series tower cranes to the Kingdom Tower project in Jeddah, Saudi Arabia.

Three 280 HC-L 16/28 cranes and one 357 HC-L 18/32 Litronic will be supplied to the project, with jib lengths of 40 – 45 m and lifting capacities of 11 – 12 tonnes at a radius of 35 m. The 280 HC‑L luffing cranes will be used to build the side wings of the Kingdom Tower, with hook heights reaching some 400 m. The 357 HC-L will be on the main tower, with a hook height of some 1,000 m.

To reach these heights the cranes will move upwards in several climbing stages. They will be positioned on the sky terrace of the building or on various cantilever platforms mounted on the outside of the building.

According to Liebherr, the positive experience contractor Saudi Bin Laden Group has had with its cranes on other projects were one of the main reasons for their use on the Kingdom Tower. For example, two 280 HC‑L cranes were used on the CMA Tower in the King Abdullah Financial District project in the Saudi capital, Riyadh.

The Kingdom Tower will be the first structure in the world to be over 1,000 m high. It will also have the highest ever visitor viewing platform at a height of 630 m. The skyscraper with 170 storeys is part of the “Kingdom City” urban development project in the north of Jeddah in Saudi Arabia.
