Liebherr supplies Krandienst’s first crawler

Hamburg-based crane company Autokranvermietung Krandienst Schulz has entered the crawler crane hire market with the purchase of a Liebherr LR 1600/2.

The crane features Liebherr’s new SL13 boom system, designed to assist with the erection of the latest generation of wind turbines with hub heights of more than 150m.

Krandienst has already hired the crane to a wind turbine project, with the LR 1600/2 erecting 2.5MW-class turbines at Neiler, in the Swabian Alps. The project involved lifting 63t loads to a hub height of 138m.

Company owners Günther Sichward and Michael Schmidt-Pöpping said: “We continue to see plenty of demand for cranes in the wind industry. But our large telescopic cranes are no longer suitable for erecting the latest generation of wind turbines.”

Krandienst operates 24 telescopic mobile cranes, with load capacities from 30-750t.

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.

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.”

Crawlers assist at Europe’s biggest LNG facility

A team of five Manitowoc crawler cranes are assisting the construction of what is said to be the largest liquefied natural gas (LNG) plant in Europe.

The cranes are being operated by Dutch crawler specialist Crane House and working up to 24 hours a day at the €1bn project at Dunkirk, France.

With capacities from 250t-400t, the cranes were first used on the site in 2011, when a Manitowoc 16000 and a 272t Manitowoc 2250 were used for six months to install underwater foundations and a floating flat barge.

In mid-2013, another 16000 joined the project, followed by a second 2250 and a Manitowoc 15000 model. The 16000, as the largest crane on the site, is rigged with a 96m boom.

The cranes have worked along the shoreline at the project, with one assembled on an off-shore platform. They were recently used to assist the construction of the terminal jetty, primarily through pouring concrete.

The project, which is being overseen by a consortium lead by French contractor Vinci, is due to be completed next year.
