Abstract
Provided is a weighing device for determining a property of a rotor blade of a wind turbine. The weighing device includes a first seat for receiving the rotor blade at a first radial position of the rotator blade, a second seat for receiving the rotor blade at a second radial position of the rotor blade, a first weight cell for quantifying a first weight which is acting on the first weight cell, a second weight cell for quantifying a second weight which is acting on the second weight cell, and a first counterweight which is configured to alleviate the first weight. Notably, the first counterweight is lifted up from the ground when the rotor blade is received by the first seat of the weighing device. Furthermore, a method of determining the weight, the mass or the torque of a rotor blade of a wind turbine is also provided.
