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.

Liebherr crane assists fertile growth in Indonesia

A Liebherr LR 11350 crawler crane has been used to perform a single lift and a tandem lift at a fertiliser plant in Palembang, Indonesia.

Overseen by GTA Construction and performed on behalf of a joint venture between an Indonesian EPC company and a Japanese EPC contractor, the tandem lift took two hours and involved lifting a 787t ammonia converter into position at the facility. As well as the 1,350t-capacity LR 11350, a 550t tandem crane was also used.

GTA’s general manager for construction, Mr E Warman said: “The main benefit of the LR 11350 for this particular tandem lift was that the counterweight for the super-heavy lift function is easier to adjust than on competitive models.

“This allowed the lift to be completed more easily as the crane was more manoeuvrable in the confined working conditions of the site, which other than limited space presents no other difficulties.”

GTA has previously used the Liebherr LR 11350 to lift a 607t CO2 absorber, using the 550t crane as a tailing crane.

Kran Saller erecting wind turbines

A 750t Liebherr LTM 1750-9.1 crane has been used by German crane company Kran Saller to erect wind turbine towers.

Kran Saller, based in Deggendorf, added the crane to its fleet in July and recently used it to erect 89m-high concrete tower for 12 wind turbines.

The project, at the Berngerode wind farm at Schlitz, involved erecting the towers for 2.5MW wind turbines manufactured by GE. The crane was equipped with a Y-guying system and a 35m luffing jib.

Following that stage, Kran Saller used a Liebherr LR 1600/2 crawler crane to install segments of the steel tubular tower to the hub height of 139m, as well as the nacelle, hub and blades.

At almost 80t, the foundation rings were the heaviest components, with the steel tubular tower segments weighing in at 55t.

As the LTM 1750-9.1 is the largest crane in Kran Saller’s fleet, the crane company added to the crane’s livery the name ‘Big Red One’. The next project planned for the crane by Kran Saller is erecting three wind turbines at the Hohenstein wind farm near Wiesbaden.

ALE completes Australian projects with Liebherr crane

ALE has completed a number of projects in Australia using its 1,350t Liebherr LR11350 crawler crane.
The projects, completed over the last five months, included the transportation and installation of a 605t CO2 absorber column in Darwin.

At Cape Lambert in Western Australia, ALE installed two 400t car dumper cells using the LR11350.

ALE’s projects and technical director Filippo Anello said of the project in Darwin: “With limited space for the positioning and manoeuvring of the crane on a live gas plant, the lift and transport planning were carefully engineered to complete the operation safely.”

Liebherr upgrades flat-top crane

Liebherr has introduced its 172 EC-B 8 Litronic flat-top crane, based on the established 160 EC-B model.

Lifting capacity has been increased by 15%, with the 172 EC-B 8 capable of hoisting 2,100kg at the jib head at a radius of 60m, and an 8t maximum capacity.

The new model also features a new jib erection concept. The load hook and trolley remain on the jib pivot section during transport, eliminating erection work for the trolley.

The hoist and trolley travelling ropes can also be easily reeved, a particular benefit when erecting the jib in the air, says Liebherr.
