The metallurgical overhead crane (hereinafter the crane) is dedicated lifting equipment for metal smelting environments. It has a single lifting point with a forged hook carrying a gantry-type spreader for handling liquid molten metal, and is fitted with safety brakes and other protective devices; critical areas are protected against high temperature — for example heat insulation under the main girder, steel-core wire ropes, and high-temperature cables for the trolley festoon routed inside the walkway. The crane provides vertical lifting plus longitudinal and transverse travel and can carry materials and pour molten metal intermittently and repeatedly during smelting. Duty classes A6–A8.

The QZ grab overhead crane uses a four-rope grab as its dedicated load-handling device to handle bulk materials such as ore, lime, raw coal, sand, coke, cement and slag. The design is proven and reliable, with flexible configuration, fast working speeds, high efficiency and good expandability. It suits warehouses, material yards and workshops.

The electric hoist gantry crane is one of the most widely used hoisting machines. Its hoisting mechanism is an electric hoist, and it runs on ground rails supported by legs on both sides, handling intermittent and repetitive loading, unloading and transfer of materials and equipment in normal working environments with vertical lifting plus longitudinal and transverse travel. The legs can carry cantilevers on the outside to transfer items out of the bay, or can be supplied without cantilevers.

The rail-mounted container gantry crane (RMG) is large handling equipment running on fixed rails, mainly used for efficient loading, unloading, transfer and stacking of containers in ports, railway yards and container depots.

The shipyard gantry crane is overhead-type lifting equipment installed on rails in docks and on slipways. It has a portal frame structure (double or single girder) supported by a combination of rigid and flexible legs, meeting complex operations such as lifting, turning and joining hull blocks.

The electric hoist overhead crane is one of the most widely used hoisting machines. Its hoisting mechanism is an electric hoist; it handles intermittent and repetitive loading, unloading and transfer of materials and equipment in normal working environments with vertical lifting plus longitudinal and transverse travel.

The electric single girder crane (hereinafter the crane) is one of the most widely used hoisting machines. Its hoisting mechanism is an electric hoist; it handles intermittent and repetitive loading, unloading and transfer of materials and equipment in normal working environments, with vertical lifting plus longitudinal and transverse travel.

The wire rope electric hoist is compact, light, small in size, with highly interchangeable parts and easy operation. It is mainly used for lifting, pulling and loading/unloading loads, and can be mounted on an I-beam on its own or supplied with electric or manual single girder, double girder, cantilever or gantry cranes.

The suspended electric hoist overhead crane runs on a track fixed directly to the building structure (roof trusses or columns). It suits workshops with restricted space or flexible layout requirements. The hoisting mechanism is an electric hoist; the crane handles intermittent and repetitive loading, unloading and transfer of materials and equipment in normal working environments with vertical lifting plus longitudinal and transverse travel.
