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.

New Sennebogen telecrawler increases capacity

Sennebogen has introduced its 6113, a 120t telecrawler which extends the maximum safe working load of its range by 50%.

The German crane manufacturer’s series of telecrawlers previously ranged from 8-80t. The 120t 6113 model increases maximum capacity while retaining the full-power boom incorporated in all of Sennebogen’s telecrawlers — a maintenance-free system which uses multi-cylinder technology to provide continuous friction-locked telescoping of the boom.

The crane has a length of 40m, with heights of 70m possible with fly boom and lattice boom extensions.

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.
