Terex TC 2800-1 crane erects a wind turbine at 2,465 metres
Welti-Furrer Pneukran & Spezialtransporte has erected a 2.3 megawatt wind turbine at an altitude of 2,465 metres, near the border between Switzerland and Italy. A Terex TC 2800-1 lattice boom truck crane was used for the main lifts. Erecting the wind turbine at the high altitude of the Swiss Alps involved a series of challenges. For example, the roads for transporting the cranes and components were narrow and winding.
“This is where the Terex TC 2800-1′s compact design and comparably small weight came in, as it allowed us to avoid doing any damage to the roads,” explained Tobias Schöpfer, head of communications at SwissWinds Development, the company responsible for planning and realising the project.
The TC 2800-1 has a capacity of 600 tonnes. Its star-type outriggers allow for a maximum support base of 14 by 14 m, which provides a high level of stability. In addition, this large support area allows the crane to provide superior lifting capacities and enables it to perform safe work even when used with long boom lengths. The machine can achieve a tip height of up to 192 m, and has a maximum main boom length of 138 m.
