The plate-shaped parts in the recess 3 rest on the load-bearing skirt 4, and the gravity received by the load-bearing skirt 4 is evenly distributed to the load-bearing beam 1, so as to avoid the stress concentration of the spreader. The limiting arms 2 located at both ends of the load-bearing beam 1 realize the limiting of the plate-shaped parts, so as to prevent the plate-shaped parts from sliding down. Since there is enough space in the concave 3 of the spreader provided in the present disclosure, it can accommodate plate-shaped parts with sufficient thickness and a sufficient number of plate-shaped parts, which improves the efficiency of transfer and hoisting. In addition, since the load-bearing skirt 4 is arranged in the spreader, the load-bearing area of the spreader for the plate-shaped parts is relatively large, so in the process of transferring and hoisting, it can be easily adapted to plate-shaped parts of various shapes, avoiding the need for It solves the problem of repeatedly adjusting the balance hoisting point due to finding the center of gravity of the plate-shaped parts, thereby further improving the efficiency of transfer and hoisting.
