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.

Ale and Aertssen will oversee largest lift Antwerp

More details have been revealed on the heavy lift project being undertaken at Total’s Antwerp petrochemical complex by ALE and Aertssen.
First announced in mid-November, the project will be undertaken by ALE and Belgian company Aertssen, the first job to be performed by the joint venture.

A load of 1,050t, measuring 24m long, 11m wide and 23m high, will be transported 5km along Scheldelaan, from a quay to the refinery. Set for delivery on December 2, it will represent the largest-ever cargo to pass through the Port of Antwerp.

The job is one part of a six-month project which ALE and Aertssen began in October for Total. The joint venture has been transporting modules using 80 axle lines of SPMTs, and installing the modules using telescopic and crawler cranes.

Gammon meets requirements with Liebherr cranes

Gammon Construction has purchased two Liebherr 380 EC-B 16 Litronic flat-top cranes to assist construction of the Midfield Concourse project at Hong Kong International Airport.
The 16t cranes are being used as part of the HKD6.2bn ($800m) contract awarded to Gammon by Airport Authority Hong Kong, and were delivered to Gammon by Liebherr’s Hong Kong distributor Shriro Machinery Co.

The project involves the construction of a new passenger concourse, to increase the number of passenger aircraft stands and meet future demand at the airport.

The cranes are based on the 355/380 IC tower system, suited for very narrow sites and for floor-climbing, says Liebherr.

William Tang, sales manager at Shriro, said: “This is the Hong Kong debut for the EC-B. The cranes are being used mainly for lifting steel structural frame elements and beams. The loads will weigh up to 12 t or more, and the specifications for the 380 EC B 16 Litronic are such that the two cranes will be handling all the primary lift requirements on the steel structure.”

The building is due to be finished in September 2015 and will feature 19 aircraft stands, fixed link bridges and aircraft loading bridges, as well as an extension of the APM tunnel from Terminal 1 to the concourse, an extension of the South Runway Road, and a new taxiway.

Liebherr subsea crane lifted by four mobile cranes

Liebherr used two mobile harbour cranes and two lattice boom mobile cranes to lift its new RL-K 7500 subsea crane ahead of shipment to Asia.

At its facility in Rostock, Germany, Liebherr used two LHM 600 mobile harbour cranes and two LG 1750 lattice boom mobile cranes to lift the RL-K 7500 onto a transportation device.

The RL-K 7500, which has a dead weight of 665t, will be delivered along with a Liebherr RL-K 4200 knuckle boom crane, to Daewoo Shipbuilding & Marine Engineering. The customer plans to equip several of its ships with a set of one RL-K 7500 model and three RL-K 4200 cranes.

The RL-K 7500 can lift up to 300t and handle loads down to a depth of 3,600m underwater.

It also features Liebherr’s AHC (Active Heave Compensation) system, which uses sensors to predict and compensate the vessel’s motion, and a horizontal winch shifting system designed to ensure the ideal fleet angle of the rope under all load conditions when both hoisting and lowering. The vertical winch frame lifting system reduces wear on the rope, extending service life.

Terex has introduced its 130t Explorer 5500 all terrain crane

Terex has introduced its 130t Explorer 5500 all terrain crane, designed to be the company’s most compact crane in its capacity class.

Part of the Explorer range which also includes the 5600 and 5800 models, the new 5500 features a 60m main boom with three extensions of 11m, 22m and 33m, with a maximum system length of 86.5m.

With a maximum load moment of 395mt, the five-axle crane is designed to be compact enough for use in cities and on other narrow construction sites. Manoeuvrability is improved by steerable axles, says Terex.

Features including variable axle loads and axle pair intervals, as well as dismountable main boom, enables the crane to be fulfil road service approval regulations in key markets.

All the components for the Explorer 5500 can be transported on one standard support vehicle, and the crane also incorporates Terex’s single-motor concept as used on the 5600 and 5800 models. This automatically adjusts the power usage according to whether the crane is driving or operating, reducing energy consumption.
