[0023] Specifically, when there is no equipment on both sides of the I-beam 17 that interferes with the lifting of the sling, the lifting mechanism of the crane can be used to first lower the sling assembly to the two sides of the I-beam 17 respectively, and then the vertical beam 2 is rotated to make the transverse blocks 6 located on the inner side of the vertical beam 2, and then the moving part 5 is used to drive the sling assembly to move horizontally until the transverse blocks 6 are located below the upper flange plate of the I-beam 17, and then the lifting mechanism of the crane is used to drive the sling assembly to rise, so that the L-shaped hook can directly hang the upper flange plate of the I-beam 17, and then the electric telescopic rod 7 can be used to drive the clamping block 8 to descend to the top surface of the I-beam 17, so that the clamping block 8 clamps the I-beam 17, so as to prevent the I-beam 17 from falling off during the lifting process.
