Unlike traditional general-purpose cranes centered on material handling, non-ferrous metal smelting cranes are deeply integrated "production partners" within the process line. Anchored by the electrolysis production process, they seamlessly couple with core procedures such as electrolysis, smelting, casting, and refining, serving as critical pivots to ensure process continuity and enhance line efficiency.
Based on differences in application scenarios, they are primarily divided into two main types: one is the aluminum electrolysis multifunctional unit specifically designed for aluminum smelting, and the other is the specialized process crane adapted for the smelting of other non-ferrous metals such as copper, zinc, lead, and nickel.
Facing the extreme composite working conditions of non-ferrous metal smelting—high temperatures, magnetic field interference, dense dust, and corrosive gases/acid mists—Weihua has developed a specialized crane with dual-drive capabilities of "environmental adaptation + intelligent empowerment," setting industry-leading standards in the field.

Weihua Aluminum Electrolysis Multi-functional Crane
The aluminum electrolysis multifunctional unit integrates core electrolysis processes such as shell breaking, anode replacement, slag removal, feeding, aluminum tapping, and hoisting into one system, serving as a key piece of equipment in large-scale prebaked anode aluminum electrolysis production lines.
Weihua's newly developed advanced three-beam aluminum electrolysis multifunctional unit is equipped with industry-leading 600kA large aluminum electrolysis cells. It features advanced configurations such as a dual anode mechanism (single-action/interlocking), an independent rotating slag removal mechanism, a flat grab function, 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.
R1: "Advancedness" must be translated as progressiveness.
The comprehensive advantages are remarkable: technologically advanced, stable performance, high operational efficiency, convenient operation, easy maintenance, and compliance with green environmental requirements. It serves as the core equipment for enhancing the automation level and overall efficiency of aluminum electrolysis production.
Electrolysis-specific cranes (for copper, zinc, lead, nickel)
Lifting capacity range: 20t-40t
Span range: 16.5m-34.5m
Work Level: A7, A8
Weihua Specialized Electrolytic Copper Crane
The electrolysis-specific crane is a high-precision intelligent equipment designed for electrolysis processes, integrating core functions such as picking up and placing cathode and anode plates, as well as transporting residual plates to the washing unit. With a positioning accuracy of up to ±2mm, it supports three operation modes: fully automatic, semi-automatic, and manual.
The accompanying HMI operating system can display coordinates, status, and fault information in real time, offering flexible and controllable operation. The entire machine undergoes special insulation and anti-corrosion treatment, resisting DC electric fields and acid mist corrosion, making it suitable for harsh working conditions. Equipped with a dedicated hoisting tool, it enables functions such as simultaneous hoisting of anodes and cathodes, single hoisting, tail hook single operation, and initial plate alignment, facilitating unmanned operation of electrolytic cells.
Nickel tank transfer special crane
Lifting capacity range: 32~100t
Function: Applied to nickel iron production lines. The crane, through programmed control, can automatically hoist and unload nickel iron roasting sand material tanks, automatically allocate and add mineral sand, and cooperate to achieve fully automatic operation of the production line.
Work level: A7, A8
Weihua Nickel Tank Transport Special Crane
The nickel tank specific crane is specially designed for the nickel iron smelting scene. The entire product set, with advantages of high temperature resistance, high precision, high efficiency, high reliability, and intelligent integration, has become the core equipment for improving the quality and efficiency of nickel smelting production lines. It is widely used in wet smelting of laterite nickel ore (RKEF process), high ice nickel smelting and other production lines, undertaking key operations such as efficient transportation of high-temperature material tanks and equipment hoisting.
This series of products has strong high temperature resistance and can directly resist the radiation heat of roasted sand and high-temperature granular metals, ensuring safe operation in extreme environments; At the same time, the efficiency is outstanding, reaching up to 10 cans/hour, with high-precision positioning and anti sway capabilities, deeply integrated automation, and linked with the factory MES system to achieve unmanned operations throughout the entire process of tank retrieval, transportation, unloading, and return, significantly improving safety and operational consistency.
Copper smelting slow cooling field metallurgical gantry crane
Lifting capacity range: 32t-100t
Span range: 6m-24m
Work level: A7, A8
Weihua Metallurgical Portal Crane
The complete set of intelligent lifting equipment for the slow cooling field of copper smelting slag consists of core equipment such as metallurgical gantry cranes, gantry spray trucks, electric flatbed trucks, and relocation platforms. It integrates infrared cameras, millimeter wave radar point cloud recognition, and weighing triple authentication strategies, and uses WCS system combined with absolute value encoder redundant positioning and magnetic nail calibration technology to achieve millimeter level accurate positioning.
The closed-loop anti sway technology based on inclinometers effectively suppresses lifting swing, ensuring the stability of slag bag automatic hanging, flipping, and unloading operations.
