BRS (Blade Rotator System); Protecting both your personnel and your product!

The BRS is designed to rotate a wind-turbine rotor blade both during manufacturing and maintenance processes and between logistic steps in the transport and installation process.
Main target for designing this product was the safety for people and maximum level of airfoil protection.

Main features of the BRS

  • Adjustable for different blade diameters
  • Suitable for pre-bended and straight blades
  • Suitable for blades with large COG shift
  • Able to use BRS outside as well as inside factory
  • Use at different stages of fabrication

Logistic improvement

  • No use of overhead crane
  • Easy operation
  • Quick (un)loading of blade
  • Positioning over any required angle
  • Blade root fully accessible
  • Maximum airfoil accessibility

Airfoil protection

  • Distributed load on airfoil surface, no point loads
  • Tip shell (optional)
  • Leading and trailing edge protector (optional)
    > No delamination

Safety

  • 100% positive control
  •  Blade gripping/clamping above blade COG
  •  Smooth take-over from hoisting sling to BRS and vice versa (no bumping, no peak stress)
  • CE compliant
