The generator house of the 2 MW wind turbines has a weight of 68t (without nose cone). The first tower section weighs 62t. The nose cone with the 3 propeller blades weighs around 42t, and each propeller blade has a weight of 7t and a length of approx. 27m.
After this project is finished, Transbiaga will use these cranes for general contracting and rental duties across Europe, and especially for the erection of wind turbines.
The company has recently received its second CKE2500-2 with special options, which is now working on wind projects, and the firm has ordered a third for delivery in 2008.
The two cranes have been fitted with retractable tracks (giving an overall width of only 4.85m in the narrow-track setting). They are thus able to travel between the turbine platform positions in hilly terrain on 5m-wide access roads.
In addition, they also have special 9.3m-long crawler frames with four travel motors (instead of the standard 2), additional track rollers and special hardened shoes, for greater manoeuvrability in the narrow track setting and increased strength and durability.
The special boom configuration includes a 61m main boom combined with a newly-developed 27.4m heavy fixed jib, giving a lift capacity of 42t at 14-15m radius, and a maximum hook height of 86.4m. Maximum configuration is 61m boom + 36.6m heavy fixed jib.
“This configuration, which has been tailor-made to our requirements, along with the famous reliability and durability of Kobelco cranes, suits this type of work, often in difficult terrain, perfectly,” says Antonio Jero Rodriguez, technical director at Spanish company Setlysa Logistica based in Madrid and part of the Gamesa Corporation.
The CKE2500-2 heavy fixed jib can easily be converted into a luffing jib with 61m tower boom + 61m luffing jib as the maximum combination, says Jos Verhulst, sales and marketing manager at Kobelco Cranes Europe.
The CKE2500-2 is powered by a 247kW diesel engine with common-rail, electric-controlled fuel injection and inter-cooled turbocharger, which is fully compliant with the worldwide Stage 3 emission standards.
