Attachment enhances turbine lift for Bäumer
05 January 2010
German rental company Bäumer has been using its new 450 tonne capacity Grove GMK7450 all terrain crane to erect a wind turbine in private land in Reinsbuttel.
The crane was configured with a mega-wing-lift attachment to erected the Enercon E-70 wind turbine which stands 113 m tall and has a 71 m diameter rotor.
Components for the wind turbine included a 45 tonne nacelle, a 54 tonne tower and 42 tonne blades.
The GMK7450 worked with 40 m of main boom and 31 m of luffing jib.
Mega-wing-lift is a capacity-enhancing attachment that provides greater stability strength in the boom, particularly when the boom is working at steep angles, says the manufacturer.
Bäumer took delivery of the Grove GMK7450 in June 2009.
