Like any piece of machinery, a wind turbine can only do its job with proper maintenance. Vibration and movement put stress on the turbine, which means the bolts holding them together must be recalibrated and retightened frequently.
It takes a lot of bolts to keep a wind turbine turning – roughly 1,500 per some estimates – which means wind turbine maintenance requires precise, durable tools.
“Because of the rigorous physical demands faced by technicians, not having the proper tool can slow down maintenance, or, more troubling, may increase the chances of a task being performed with a tool that is less than optimal,” writes Mark Del Franco in North American Wind Power.
In many cases, professionals in the wind industry turn to E-RAD when they need precision torque tools for wind turbine maintenance.
Among the features of these tools:
They are designed to provide a high level of accuracy (+/- 2.8 percent) and repeatability (+/-2 percent).
They’re faster, especially when compared to hydraulic wrenches. The electric E-RAD lessens the time it takes tighten bolts by up to 300 percent, delivering smooth, continuous torque. This is important in an industry where construction and installation can be stalled due to high winds.
E-RAD tools are lighter, with an unsurpassed power-to-weight ratio that removes the need to lug around heavy hydraulic pumps, which in turn eliminates operator fatigue.
These tools are significantly quieter than other torque systems, operating at 75 dB, and are a versatile option, with a torque range of 800 to 15,000 ft./lbs.
As we said earlier, the bolts used to fasten together wind turbines require proper calibration. In addition to renting and selling E-RAD torque equipment, we also calibrate these and other torque tools at our calibration laboratory.
Maxpro is proud of the investment it has made to become A2LA-accredited, meaning our state-of-the-art calibration lab has the blessing of the nation’s premiere ISO/IEC 17025 accreditation agency.
