Abstract

A system for lifting a wind turbine rotor blade, comprising• a wind turbine rotor blade,• a lifting device (12) having a sling (30),• the sling supporting the wind turbine rotor blade at a longitudinal position where the wind turbine rotor blade has an aerodynamic profile, a leading edge and a profile chord arranged horizontally, and• a leading edge protector having a front portion placed at the leading edge and a lower leg extending from the front portion and placed below the wind turbine rotor blade, wherein• the front portion and the lower leg are formed as a sandwich construction having an inner top layer, an outer top layer and a core material, wherein a thickness of the core material increases from a free end of the lower leg towards the front portion in order to reduce a deformation of the wind turbine rotor blade at the leading edge.
