Specific embodiment

Referring to Fig. 1 to 8

A kind of suspender (as Fig. 1) of two the unloaded freight containers of can once slinging, it adopts all-welded steel structure, and integral structure comprises that 2,3, two crossbeams of 1, two end carriage of

intermediate box beam

4,5 constitute (as shown in Figure 2).It is convenient that suspender connects with fork truck, and two arms of fork truck insert in the end carriage of both sides just can carry out handling labor.

As shown in Figure 3, in the suspender intermediate box beam oil cylinder 6 is housed, the connecting rod mechanism 7,8 that links to each other with oil cylinder, four jiaos of the case beam are equipped with 4 and ship and resell on another market 9,10,11,12.The connecting rod mechanism that is promoted by oil cylinder can drive four actions of shipping and reselling on another market simultaneously, thereby realizes opening and closing the lock action.

As shown in Figure 4, shipping and reselling on another market of suspender is distributed in four jiaos of intermediate box beam, adopts the hanger bearing mode, and spherical bearing face 13 acts on the concave spherical surface 14, suspender is shipped and resell on another market and can be swung within the specific limits like this, and making ships and resell on another market is more prone to be inserted into corner casting hole on the freight container.
