Multi-purpose crane for electrolytic copper

cn_whcrane — Thu, 18 Dec 2025 07:34:40 +0000

The electrolytic copper production environment is harsh, characterized by high humidity, corrosive gases, and metallic dust. Weihua’s multi-purpose crane for electrolytic copper is designed specifically for these special working conditions. Its main function is to safely, precisely, and efficiently complete the streamlined production operations of electrolytic copper, replacing manual labor and standard cranes.

The specific work process is as follows: It picks up the arranged cathode and anode plates from the row-spacing unit and transports them to empty electrolytic cells for installation (cell loading). After electrolysis is complete, it removes the cathode plates and transports them to the washing unit. Finally, it removes the depleted anode scrap and sends it to the washing unit. The entire process requires the crane to operate smoothly with precise positioning to avoid collision damage to the plates and ensure continuous production.

Advantages & Features

High-Precision Intelligent Positioning

The travel of the main and cross-travel mechanisms utilizes laser ranging positioning, achieving positioning accuracy of up to ±10 mm. This ensures seamless and precise docking of the spreader with equipment such as electrolytic cells and row-spacing units, significantly improving operational efficiency and success rates.

Excellent Specialized Adaptability

The product is specifically designed for electrolytic copper workshops, with materials and processes considering corrosion resistance and dust prevention. Its dedicated spreader and program logic perfectly match the production rhythm, making it irreplaceable by general-purpose cranes.

Stable & Reliable Control System

Based on Siemens high-end PLC and full inverter drive control system, it responds quickly with smooth operating curves. This not only protects mechanical equipment by reducing impact but also makes the lifting process extremely stable, preventing plate sway.

Multiple Safety Guarantees

In addition to conventional electrical protection, a combined electrical insulation方案 is designed for the high-current environment of the electrolytic workshop, ensuring safe operation and maintenance above the cells. The system features remote monitoring and fault self-diagnosis functions for advance warning.

Flexible Operation Modes

Supports three operation modes: cab operation, remote control operation, and ground station operation. This provides the most suitable control option for different production stages (e.g., commissioning, normal production, emergency handling) and lays the foundation for realizing fully automatic workshop production lines in the future.

Structural Composition

The multi-purpose crane for electrolytic copper is a specialized and intelligent product that deeply integrates process and equipment. It solves material handling challenges in electrolytic copper production through high-precision positioning, dedicated spreaders, and a stable and reliable control system. Its main components are as follows:

Bridge Structure: Box girder design, offering high strength and torsional resistance; the surface is treated with special anti-corrosion coating to adapt to the corrosive environment of the electrolytic workshop.
