When the lifting appliance provided by the embodiment of the disclosure lifts plate-shaped parts (to-be-lifted objects), the plate-shaped parts can be sequentially stacked in the recess 3 enclosed between the bearing beam 1 and the limiting arm 2. The plate-shaped parts in the recesses 3 rest on the load-bearing skirt 4, and the gravity on the load-bearing skirt 4 is uniformly distributed to the load-bearing beam 1, so that the stress concentration of the lifting appliance is avoided. And the limiting arms 2 positioned at the two ends of the bearing beam 1 realize the limiting of the plate-shaped parts so as to prevent the plate-shaped parts from sliding off. Because in the hoist that this disclosure provided, its sunken 3 has sufficient space in, so can hold plate-like part and abundant plate-like part thick enough, improved the efficiency of transporting hoist and mount. In addition, because the load-bearing skirt 4 is arranged in the lifting appliance, the load-bearing area of the lifting appliance on the plate-shaped parts is larger, so that the lifting appliance can be easily adapted to the plate-shaped parts with different shapes in the transferring and lifting process, the problem that the balance lifting point is repeatedly adjusted due to the fact that the gravity center of the plate-shaped part is found is solved, and the transferring and lifting efficiency is further improved.
In the present embodiment, the hoisting ends 22 of the two limiting arms 2 are provided with end chamfers 51.
In the above implementation manner, since the hoisting end 22 of the limiting arm 2 directly protrudes upwards from the bearing beam 1, the end chamfer 51 is arranged on each hoisting end 22, so that personnel injury can be avoided. In addition, the end chamfer 51 can avoid interference collision with the lifting hook installed in the lifting hole 23, and plays a role in protecting the lifting hook.

The inner chamfer 52 is used for protecting the object to be hung and preventing the object to be hung from being scratched.
Optionally, the bearing beam 1 and the two spacing arms 2 are of an integrated structure.
In the implementation mode, the structural integrity of the lifting appliance can be guaranteed, the overall structural strength of the lifting appliance is improved, and the lifting appliance is convenient to produce and manufacture.
In other embodiments, the connection mode between the bearing beam 1 and the two limiting arms 2 may also be adjusted according to actual requirements, for example, the bearing beam 1 and the two limiting arms 2 may also be connected together by means of welding, which is not limited by the present disclosure.
Illustratively, the spreader may be a steel structural member.
In the implementation mode, the lifting appliance is set to be a steel structural part, so that the structural strength of the lifting appliance can be ensured.

In this embodiment, the load-bearing skirt 4 is a plate-like structure, and the load-bearing skirt 4 is perpendicular to the axes of the two position-limiting arms 2.
In the above implementation, the load-bearing skirt 4 is configured as a plate-shaped structure, so that the load-bearing area of the load-bearing skirt 4 can be further increased to avoid stress concentration. And because when the plate-shaped part is laid on the bearing skirt 4, the plate-shaped part is parallel to the bearing skirt 4, so that the bearing skirt 4 is perpendicular to the axes of the two limiting arms 2, the plate-shaped part laid on the bearing skirt 4 can be ensured to be perpendicular to the axes of the two limiting arms 2, and the two limiting arms 2 can limit the plate-shaped part more conveniently.

In the above implementation, since the load beam 1 has a plate-shaped structure, both sides of the load-bearing skirt 4 protrude from the load beam 1 in order to package a sufficient load-bearing area of the load-bearing skirt 4.
Optionally, the load bearing skirts 4 are symmetrically arranged with respect to the load bearing beam 1.
In the implementation mode, the overall balance of the lifting appliance can be improved, the lifting appliance is prevented from inclining in the lifting process, and the reliability of the lifting appliance is improved.
Illustratively, the load bearing skirt 4 and the load bearing beam 1 are welded together.
In the above implementation manner, since the two sides of the bearing skirt 4 protrude from the bearing beam 1, it is inconvenient to manufacture the bearing skirt 4 and the bearing beam 1 integrally.
