Abstract
A movement system includes a bridge crane, a trolley, and a movement device. The movement device includes an attachment portion, a plurality of housings, first and second curved elements, a cable, and a cable angle sensor. The curved elements are pivotally attached to housings and perpendicularly overlap with one another such that a first slot defined in the first curved element is perpendicular to a second slot defined in the second curved element. The first curved element is pivotable about a first axis and the second curved element is configured to pivot about a second axis. The cable extends from the attachment portion and through each of the slots. The cable is pivotable to angularly displace at least one of the curved elements about a respective axis. The cable angle sensor is configured to measure the angular displacement of the at least one of the first and second curved elements.
