The LR 11000 from Liebherr packs a punch: higher wind turbines and heavier nacelles

To build taller wind turbines with corresponding hub heights and heavier nacelles in the future, the Dutch crane rental company Verschoor decided to acquire a Liebherr LR 11000 crawler crane. The company is thus meeting the requirements of wind turbine manufacturers by adding the most powerful crane to date to its fleet.Verschoor 's LR 11000 on its first job at the Vanikum wind farm. Verschoor expands its fleet with its most powerful crane to date LR 11000 proves its worth in initial use during the installation of two wind turbines at the Vanikum wind farm Liebherr’s innovative strength and solid products win over customers A new LR 11000 has joined the fleet of Dutch crane rental company Verschoor, which also includes two LG 1750 and an LG 1550. From port operations to infrastructure projects, this crawler crane covers a wide range of applications thanks to its boom variants. At Verschoor, the crane will primarily be used for wind power projects – the new LR 11000 has already proven itself during the installation of two new wind turbines at the Vanikum wind farm near the Dutch border in North Rhine-Westphalia. The LR 11000 lifts a 75-metre-long rotor blade to a height of 169 metres for installation. The LR 11000 assembled various components such as the tower sections, nacelle and rotor blades at a height of 169 metres. At 117 tonnes, the heaviest single component was the gearbox. The crane was set up for the lifts with a 168 metre long main boom and 15-metre lattice type fixed jib. The LR 11000 is characterised by its economical transport concept and is designed for a transport width of 3.5 metres and a transport height of 3.2 metres. The V-frame® with its adjustment distance of 17 metres moves the derrick ballast into the required position and reduces the workload for ballast handling.

Lifting power was a key selling point When choosing the LR 11000, Verschoor was primarily interested in the crane’s large lifting capacity at height. “The lifting power of the LR 11000 is enormous,” says Maarten Verschoor Jr. who now manages the company in its second generation. The ability to transport the crane within the weight limits also played a role in the company’s purchase decision. “It was also important for us to have crawler cranes in our fleet in addition to jib cranes,” adds account manager Peter Verschoor. The LR 11000 lifts the nacelle onto the tower of the wind turbine. “For us, Liebherr is and remains the world’s No. 1 crane manufacturer. The developments and inventions that Liebherr offers are progressive and fulfil our expectations. We appreciate the German down-to-earth attitude and solidity,” says Verschoor Jr. with great satisfaction. Of the roughly 70 machines in his fleet, around half are Liebherr cranes. However, the LR 11000 is the largest and heaviest crane in Verschoor’s history. The Sassenheim-based company celebrated this milestone in style. Soon they will be turning in the wind: the LR 11000 attaches the rotor blades. In honour of the company’s founder, the crane was christened “M.V. Senior”. “I’m very proud to have lived to see this special moment and would never have imagined what we would achieve with our initial ‘small shop in Sassenheim’,” says a delighted Maarten Verschoor Sr. www.liebherr.com Powered by Induportals Media Publishing
