[0002] With the increase of container operation amount, the types of containers needed to be hoisted are also increasing. When hoisting open-top containers (extra-wide containers) in daily operation, it is found that the guide plate installed on the sling cannot "hold" the open-top container because the transverse width is greater than that of ordinary containers, and the sling guide plate can only be abandoned. The absence of the sling guide plate, a positioning "god", during hoisting seriously affects the success rate of the sling lock head entering the container lock eye, greatly reduces the operation efficiency, and increases the risk of damaging the tarpaulin of the open-top container.
