In order to cope with different shapes and sizes of hoisting objects, the existing lifting appliance mainly adopts several conventional solutions. First, a multi-purpose hook is used, which is designed to adapt to various shapes of hoisting objects, but often needs manual adjustment, which is relatively cumbersome to operate. Second, replaceable hooks are used, that is, different types of hooks are replaced to adapt to different hoisting needs, which improves flexibility but also increases equipment cost and maintenance difficulty.
