MANY WHEELS MAKE FOR STABILITY
THE most wheels that Wheels can report on this month were spotted between Velddrif and Vredenburg on the West Coast, where the last giant wind turbine blade was last week hoisted into place.
At about 50 metres, each blade is half as long as a soccer pitch, and weighs about seven tons. It takes less than a day to pull the tower up for the wind turbine, but twice that time to erect and dismantle the crane.
The height of these wind turbines varies from 85 metres to 95 metres.
Herman Rix, the owner of the farm where the wind is being harvested, said the 280-ton crane had put in place 46 of the wind turbines.
To support a 280-ton crane that has to lift a seven-ton blade in place on top of a 85-metre high tower requires a lot of wheels. The last of these wind turbines were erected last month at a farm on the West Coast.
