Our pick of the Hamburg exhibits

摘要

With 12,500 exhibitors at WindEnergy Hamburg, innovative technical products were in abundance. Here Eize de Vries picks a few of his favourite. Fitting increasingly longer blades to low and medium-wind models is an ongoing industry trend, to both exploit previously uneconomic wind sites and to further drive down the cost of energy. Prominently displayed outside the event was the 64.4-metre long and slender Nordex NR 65.5 blade for the N131/3000 IEC ⅢA turbine. The huge blade was mounted on a self-propelled multi-wheel "blade lifter" equipped with a pivotable blade adaptor, a high-tech development by German heavy transport specialist Scheuerle.
