Liebherr cellular crane conquers wind turbine restore at gusty mountain ridge

Windy places are nice for working wind generators. However robust winds make erecting new wind generators a problem. These robust winds additionally create challenges when repairing outdated generators that want new rotors, gearboxes, and different elements.

Regardless of the gusty circumstances current at a wind farm in Styria, Austria, Felbermayr deployed a Liebherr LTM 1300-6.3 cellular crane to deal with the job. The cellular crane helped allow the exact substitute of a gearbox on an 18-year-old wind turbine. This faulty gearbox on the Steinriegel wind farm was positioned on a mountain ridge at an altitude of virtually 1,600 metres.

Liebherr’s cellular cranes outfitted with a 90-metre growth include WindSpeed load charts for circumstances with excessive wind speeds. If the wind velocity measured on the crane’s growth exceeds the set desk wind velocity throughout a job, the crane operator can swap to a lifting capability desk with a better most wind velocity in order that, ideally, they will proceed the work.

These WindSpeed load charts got here in useful for Felbermayr who, regardless of gusts of as much as 13 metres per second, was in a position to configure the load chart to accommodate the wind circumstances.

“Because the day went on, the gusts received stronger and stronger and I switched straight to the wind chart,” studies Robert Fuhrmann, who operates the 6-axle crane for Felbermayr. “I configured the load chart, which permits me to work at wind speeds of as much as 13.4 metres per second.”

As a rule, the lifting capacities of cranes are calculated for speeds of as much as 9 metres per second. Nonetheless, Liebherr has prolonged this vary with the tailored WindSpeed load charts. Throughout pure telescopic operation of LTM cranes, lifting work at wind speeds of as much as 15.6 metres per second is feasible.
