vehicles the six- and 12-metre long segments of the main boom, luffing jib and fixed jib can be pushed into each other three times.
The crane was assembled in the HSL4 boom configuration with a 165-metre main boom and a 12-metre lattice type fixed jib. The HSL4 is currently the most powerful system available for the LR 1800-1.0 for wind power installations. With a 174-metre main mast and 21-metre lattice type fixed jib, it can erect wind turbines with a hub height of up to 179 metres.
The crane was ballasted with 170 tonnes on the slewing platform, 70 tonnes in the undercarriage, and a further 400
tonnes of suspended ballast. The total ballast is only required for erecting the boom, after which the crane was able to carry out the lifts with only a small amount of ballast on the VarioTray. A 68-tonne nacelle, a 74-tonne
drivetrain, and 63-tonne hub had to be lifted to a radius of around 28 metres for each wind turbine. These comparatively easy-to- assemble tower elements weighed 76, 73, and 51 tonnes respectively. Once the first turbine had been assembled the team had to completely dismantle the LR 1800-1.0 and reassemble it near the second system 300 metres away. The task took six people and a 100-tonne auxiliary crane and was accomplished within
a week. The heaviest components were the two 60-tonne crawler carriers. The slewing platform could then be quickly connected to the centre section of the chassis using Liebherr’s Quick Connection.
MOBILE MANOEUVRES it is not only crawlers being used. Bremen-based Sommer Kranverleigh has added a Liebherr mobile crane, an eight-axle LTM 1650-8.1 equipped with 54 and 80 metre telescopic booms, to its fleet. Sommer is planning to use
it for the construction – and the dismantling – of wind turbines, as well as for industry and infrastructure projects. Its first job was to dismantle six old wind turbines in Schleswig-Holstein.
COLLETT SUCCESSFULLY DELIVERS 88 WIND TURBINE COMPONENTS IN IRELAND
Collett Transport, a leading specialist in wind turbine logistics and transport, has successfully delivered 88 wind turbine components for Drumlins Park Wind Farm project in Ireland. Before the deliveries, Collett undertook a trial run to identify potential challenges along the route for the blade and turbine sections. This practical approach resulted in essential modifications, including tree pruning and adjustments to street furniture. Collett used super wing carriers for the 65m long blades, flat-top
trailers for the additional 15m long blade tips, and tower clamp trailers for the tower sections. The longest tower section, for the top,
was 28m long and the heaviest (base) section weighed 62 tonnes. Altogether 88 components were transported. All components were loaded at Belview Port in Waterford and
transported during night-time to minimise traffic congestion. Covering a distance of 199 miles, the journey took a total travel time of nine hours. Departing at 7pm, the travel time included necessary rest breaks for the drivers and was accompanied by the Collett escort fleet and local Garda escort. The Drumlins Park Wind Farm is expected to be operational in 2024 and to generate up to 49MW of renewable energy.
