Description
Technical Field
[0001] The utility model relates to the field of steel coil hoisting, in particular to a hoisting tool capable of efficiently stacking steel coils. Background Art
[0002] Steel coil lifting refers to the process of moving steel coils from one location to another using lifting machinery. Commonly used steel coil lifting tools include hooks, ropes, clamps, etc. Steel coil lifting tools usually have strong gripping force and can firmly clamp the steel coil to ensure that the steel coil can be stably connected and suspended during the lifting process. As the demand for steel coil lifting increases, a steel coil lifting tool has been further developed.
[0003] The existing technology has the following shortcomings: steel coils in factories are usually stored in warehouses. In order to improve land utilization, factories use double-layer stacking to store steel coils without damaging the steel coils. In the process of transporting steel coils, considering driving safety, steel coils on trucks are usually placed in a single layer. Therefore, during the unloading process of steel coils, there is a problem of stacking steel coils. Traditional steel coil lifting tools can only lift one steel coil at a time and stack them in sequence, which greatly reduces the efficiency of lifting, especially when a large number of liftings are required, which consumes a lot of time and human resources. Moreover, the method of placing steel coils one by one will take up a lot of ground space. This linear stacking method may lead to inefficient site utilization, especially in an environment with limited space, and the lifting process may not be effectively organized and managed.
[0004] Therefore, it is necessary to invent a lifting tool that can efficiently stack steel coils. Utility Model Content
