1. A multi-component load cell calibration device, comprising:
a base plate;
a first pillar vertically coupled to the base plate;
a second pillar vertically coupled to the base plate;
a third pillar connecting the first pillar and the second pillar and disposed parallel to the base plate;
a rotation table disposed on the base plate and configured to support a multi-component load cell and rotate about an axis defined in the multi-component load cell;
a load cell adapter disposed above the rotation table and configured to contact the multi-component load cell and rotate about a rotation axis that coincides with the axis of the multi-component load cell;
a pulley pillar coupled to the load cell adapter and configured to maintain a fixed state when at least one of the rotation table or the load cell adapter is rotated;
a first pulley disposed on the load cell adapter;
a second pulley disposed on the load cell adapter and disposed symmetrically with the first pulley with respect to the rotation axis and configured to be interlocked with the first pulley;
a third pulley disposed on the pulley pillar;
a fourth pulley disposed on the pulley pillar to be symmetrical with the third pulley with respect to the rotation axis;
a wire cable wound around at least one of the first pulley, the second pulley, the third pulley, and the fourth pulley;
a first actuator disposed on the first pillar and configured to move along the first pillar, the first actuator being connected to the wire cable and configured to apply a load to the wire cable in a predetermined direction in a predetermined plane orthogonal to the rotation axis;
a wire bracket disposed on the second pillar and configured to move along the second pillar, and connectable to the wire cable; and
a second actuator coupled to the third pillar and configured to apply a load to the pulley pillar in an axial direction of the rotation axis.
