Weihua Product Catalog: Non-Ferrous Metal Series Cranes
Unlike conventional general-purpose cranes that focus primarily on material handling, specialized cranes for non-ferrous metal smelting are “production partners” deeply embedded in the process line. Anchored in the electrolytic production process, they seamlessly integrate with core operations such as electrolysis, smelting, casting, and refining, serving as key enablers for ensuring process continuity and enhancing production line efficiency.
Based on application scenarios, they are mainly divided into two categories: one is the aluminum electrolysis multi-purpose crane specifically designed for aluminum smelting, and the other is specialized process cranes tailored for the smelting of other non-ferrous metals such as copper, zinc, lead, and nickel.
In response to the extreme composite working conditions of non-ferrous metal smelting—characterized by high temperatures, magnetic field interference, heavy dust, and corrosive gases/acid mists—Weihua has developed non-ferrous metal cranes driven by the dual engines of “environmental adaptability + intelligent empowerment,” creating industry-leading specialized cranes.

Weihua Aluminum Electrolysis Multi-Purpose Crane
The aluminum electrolysis multi-purpose crane integrates core electrolytic process operations such as crust breaking, anode changing, slag raking, material feeding, aluminum tapping, and lifting. It is key equipment for large-scale prebaked anode aluminum electrolysis production lines.
Weihua’s newly developed three-girder aluminum electrolysis multi-purpose crane is designed to complement the industry-leading 600kA large-scale aluminum reduction cells. It is equipped with advanced features such as a dual-anode mechanism (independent/linked operation), an independent slewing slag raking mechanism, a grab with flat-pickup capability, a precise aluminum tapping system, an automatic anode height measurement system, an intelligent operation and maintenance system, and a grating isolation system, enabling intelligent control and efficient operation.
Its comprehensive advantages are significant: advanced technology, stable performance, high operational efficiency, convenient operation, easy maintenance, and compliance with green environmental requirements. It is core equipment for enhancing the automation level and overall efficiency of electrolytic aluminum production.

Weihua Specialized Crane for Electrolytic Copper
The specialized crane for electrolysis is a high-precision intelligent equipment designed specifically for electrolytic processes. It integrates core functions such as picking up and placing cathode and anode plates, and transporting residual anodes to the washing unit. Its design positioning accuracy is as high as ±2 mm, supporting fully automatic, semi-automatic, and manual operation modes.
Equipped with an HMI operating system that displays real-time coordinates, status, and fault information, the crane offers flexible and controllable operation. The entire machine undergoes special insulation and anti-corrosion treatment to resist direct current electric fields and acid mist corrosion, adapting to harsh working conditions. It is equipped with a dedicated spreader capable of functions such as lifting cathodes and anodes together or separately, independent tail hook operation, and starting sheet stacking, facilitating unmanned operation in electrolytic cells.
Specialized Crane for Nickel Tank Transfer
| Parameter | Specification |
|---|---|
| Lifting Capacity Range | 32–100t |
| Function | Applied in nickel-iron production lines. Through program-controlled operation, the crane can automatically pick up and release nickel-iron calcine tanks, automatically distribute and add ore, enabling fully automated operation of the production line. |
| Working Class | A7, A8 |
Weihua Specialized Crane for Nickel Tank Transfer
The specialized crane for nickel tanks is specifically designed for nickel-iron smelting applications. With its advantages of high-temperature resistance, high precision, high efficiency, high reliability, and intelligent integration, this product has become core equipment for improving quality and efficiency in nickel smelting production lines. It is widely used in production lines such as laterite nickel ore hydrometallurgy (RKEF process) and high‑grade nickel matte smelting, undertaking key tasks such as efficient transfer of high‑temperature material tanks and equipment lifting.
This series of cranes features strong high‑temperature resistance, directly withstanding radiant heat from calcine and high‑temperature metal particles, ensuring safe operation under extreme conditions. It also delivers outstanding efficiency, with a maximum handling capacity of up to 10 tanks per hour. Equipped with high‑precision positioning and anti‑sway capabilities, it is deeply integrated with automation systems, interfacing with the plant’s MES to achieve unmanned operation throughout the entire process of picking up, transporting, discharging, and returning tanks, significantly improving safety and operational consistency.
Metallurgical Gantry Crane for Copper Smelting Slow Cooling Yard
| Parameter | Specification |
|---|---|
| Lifting Capacity Range | 32t – 100t |
| Span Range | 6m – 24m |
| Working Class | A7, A8 |
Weihua Metallurgical Gantry Crane
The complete set of intelligent lifting equipment for the copper smelting slag slow cooling yard consists of core components such as a metallurgical gantry crane, gantry spraying vehicle, electric flat car, and car transfer table. It integrates a triple verification strategy combining infrared cameras, millimeter-wave radar point cloud identification, and weighing systems. Utilizing a WCS system along with redundant absolute encoder positioning and magnetic nail calibration technology, it achieves millimeter-level precise positioning.
The closed-loop anti-sway technology based on an inclinometer effectively suppresses lifting sway, ensuring stable operations during automatic ladle engagement, tilting, and disengagement.
