ENERGY Ӏ ONSHORE WIND POWER
just one end; the tip sticks up in the air supported only by the strength of the blade. Hence it is easier to negotiate corners – and indeed hairpin bends; the blade tip can hang far over the edge of the roadway.
An added complication is that
blades are designed to catch the wind – so the precise angle of rotation along its axis at which the blade is held matters a lot. The BladeMAX1000 blade
lifter from Cometto, part of trailer
specialist Faymonville, has a load moment of 1000 metre-tonnes. This, the company claims, is the highest value on the market. The manoeuvrability allows
blade transport through winding mountain passes, challenging urban areas, and densely forested regions. Adrian Zingan, product manager at Cometto, explains what is important in use. "The rotor blades can be raised by up to 60 degrees if necessary and also
rotated by 360 degrees around their own axis. It all depends on the obstacle on the road section and the prevailing wind direction. Optimum handling stability is guaranteed by the similarly patented stability control system. Several sensors transmit data in real time, which is processed by a central control unit. In this way, all safety-relevant information is constantly monitored." In June, the Faymonville Group (which also owns the MAX
LIEBHERR CRAWLER FOR VERSCHOOR IS NOW MOST POWERFUL IN ITS FLEET
Dutch crane and transport specialist Verschoor has expanded its fleet with the addition of a Liebherr LR 11000. It is the most powerful crane in its fleet and will primarily be used for wind work. The company has already used the crane to install two wind turbines at the Vanikum wind farm near the Dutch border. Verschoor purchased the crane in order to futureproof its capability to instal increasingly taller wind turbines with corresponding hub heights and heavier nacelles. For the work at Vanikum the LR 11000 assembled various components, such as the tower sections, nacelle and rotor blades, at a height of 169 metres. The heaviest single component it lifted was the gearbox which weighed 117 tonnes. The crane was set up for the lifts with a
168-metre-long main boom and 15-metre lattice type fixed jib. According to Liebherr, 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. “The lifting power of the LR 11000 is enormous,” said Maarten
Verschoor Jr. who manages the company. 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,” added account manager Peter Verschoor.
