Abstract
An apparatus and method for controlling the position of the tongs of a crane depending on bending of a slab are disclosed. Side surface detection units are installed at both ends of the tongs of a crane for gripping the side surfaces of one or more slabs, and are configured to detect one or more gaps generated due to bending of one of the slabs. A distance detection unit is configured to detect the distance between an uppermost slab and the crane. A control unit is configured to adjust the final grip position of the tongs using information about the gaps generated due to the bending of the slab. The information about the gaps is detected by the side surface detection units and the distance detection unit.
