ematec AG, a German manufacturer of special-purpose machines, has announced its RBT Rotor Blade Lifter.
According to ematec, Nordex AG is already utilizing the new technology. Currently, the ematec RBT Rotor Blade Lifter is being used to help install eight Nordex N117/2400 wind turbines at a wind farm in Zoschingen, Bavaria.
The ematec Rotor Blade Lifter features multi-joint gripper arms and large rubber-coated pressure plates, and the rotor blade can be tilted at an angle of -10 to +95 degrees in order to keep the wind attack surface as small as possible, ematec adds.
The design allows tilting around its longitudinal axis by +/-6 degrees, thus allowing the operator to compensate for an out-of-center attachment without requiring several attaching attempts or balancing out of the rotor blade. Further, the company says, the rotor blade can be transported in a horizontal position at all times.
