The kbk combination crane consists of aluminum alloy kbk standard components, which can be used only by a bolt connection between the various instructional modules, save the space and size of the plant, thereby reducing energy consumption, enabling the rapid and reliable completion of material delivery within a given area and the precise positioning of the various components, enabling the system to operate manually, as well as active, semi-active and efficient. It is possible to hang briefly on the building roof or upper structure, and the crane tracks do not require rated support, either in part or in full, which can be installed with a slightly less reliable cost. Combination cranes are capable of carrying out difficult lifting tasks and of carrying out frequent high shelf material delivery operations; they can be installed on any general 15-cm reinforced condensing surface, without putting pressure on the roof structure of the building, using pre-standard model grouping planning structures that can easily follow the expansion of the operations unit centre。
