According to the present invention, a lifting apparatus of a crane is used by being connected to the hook of the crane through a wire rope, and comprises: a lifting beam having lugs installed to be fixed to both ends thereof and used to fasten the wire rope to be connected to the crane; a pair of rail grooves formed on the upper surface of the lifting beam in parallel; first and second trolleys installed to be able to move along the rail grooves on the upper surface of the lifting beam; and first and second hooks used to fasten the lugs of a to-be-worked object by being installed to be extended from the first and second trolleys, respectively. A distance between the first and second trolleys can be adjusted according to a distance between the lugs of a to-be-worked object, which are fastened to the first and second hooks. Therefore, according to the present invention, the lifting apparatus of the crane has an improved and extended structure to be commonly used for various to-be-worked objects, thereby reducing manufacturing costs and improving productivity and work efficiency in the processes of handling, transporting, and assembling the to-be-worked objects using the crane. |
