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.

Apparatus for controlling the position of crane tong according to slab bending and the method thereof

Disclosed herein is an apparatus and method for measuring the center of gravity of slabs. The apparatus for measuring the center of gravity of slabs includes a main system, a gravity center measurement system, and an unmanned crane. The main system provides information about the dimensions and/or weight of each of a plurality of slabs loaded in a vehicle. The gravity center measurement system includes a photographing unit for photographing the loaded slabs to be moved, a driving unit for moving the photographing unit up and down, and a control unit for calculating the center of gravity and grip position of all of the slabs, to be moved each time, based on information about a position and configuration of each of the slabs from the photographing unit and the information about the dimensions and/or weight of each of the slabs from the main system. The unmanned crane grips and moves the slabs according to the grip position information calculated by the gravity center measurement system.
