Special lifting equipment can only be adapted to a single type of container. In order to meet the lifting operation of lifting equipment for containers of different types, most of the existing container lifting equipment adopts telescopic lifting equipment for lifting containers. However, the telescopic lifting equipment still has the following shortcomings during use:

[0003] 1. Although telescopic spreaders can meet the needs of lifting containers of different models, they often need to be used with special container cranes, which limits the use of telescopic spreaders;

[0004] 2. The telescopic spreader has a complex structure, which not only results in high cost, but also time-consuming and labor-intensive later maintenance;

[0005] 3. The space of the finished product transfer area of ​​the existing container preparation line is relatively small, and the telescopic spreader requires a large space, which is not convenient for the assembly line lifting;

[0006] Therefore, there is an urgent need for an empty container sling that can overcome the above-mentioned disadvantages. Utility Model Content

[0029] In order to facilitate the flipping adjustment of the movable end beam 4, a mounting frame 7 is provided on the upper side of the crossbeam frame 2 close to the movable end beam 4, and an electric push rod 3 for pushing the movable end beam 4 to rotate is provided on the mounting frame 7. Specifically, the mounting frame 7 is arranged on the side adjacent to the through hole c15, and a hinge ear 9 is provided on the movable end beam 4 on the same side as the through hole c15, and the telescopic end of the electric push rod 3 is hingedly connected to the movable end beam 4 through the hinge ear 9;

[0030] The other end of the lower surface of the crossbeam frame 2 is provided with a fixed end beam 6 which is parallel to and corresponds to the movable end beam 4. Both ends of the lower surfaces of the movable end beam 4 and the fixed end beam 6 are provided with locks 5 for lifting the box body. The upper surface of the crossbeam frame 2 is evenly distributed with a number of lifting ears 1.

[0031] During container lifting operations, first connect the lock of the crane to the lifting lug 1 on the upper part of the beam frame 2. Then, according to the type of container to be lifted, the staff uses the electric push rod 3 to push the movable end beam 4 at the end to flip upward. Then, through the movable end beam 4 in the middle of the beam frame 2 and the fixed end beam 6 at the other end of the beam frame 2, the lock 5 at the bottom can be used to lift small-sized containers. The movable end beam 4 in the middle of the beam frame 2 can also be pushed to flip, and the movable end beam 4 and the fixed end beam 6 at the end of the beam frame 2 can be used to cooperate to achieve the lifting operation of large-sized containers.
