Patent ID: 8701472

Claim:
A method for determining a spatial center of mass and a mass of an object using a hoisting device, the hoisting device having at least two different suspension devices, the suspension devices each having respectively a cable element and a suspension point for connecting to the object and inclination sensors for determining an inclined position of the suspension devices, the method comprising: suspending the object at at least two different object points which are connected to at least two suspension points of the hoisting device, the object being suspended cardanically on the suspension devices; orientating the object in at least two different spatial positions; measuring an orientation of the object in each of the at least two different spatial positions by at least one inclination sensor mounted on the object; measuring forces acting on the suspension devices as a result of the object being suspended for each of the at least two spatial positions, including resolving the forces acting on the suspension devices for evaluation respectively into three independent force components; determining a center of area of the object for each of the at least two spatial positions, the center of area for each of the spatial positions being located along an associated force effect line and being determined by compensating for the inclined position of the suspension devices; and determining the spatial center of mass by superimposing the force effect lines associated with the at least two spatial positions.
