The 20+5 ton bridge crane (commonly referred to as a "double-girder bridge crane" or "metallurgical crane") suitable for copper refineries is not an ordinary crane; it requires specialized design for the special environment of refineries, characterized by high temperatures, dust, strong corrosiveness, and complex operations.
Key parameters of the 20+5 ton bridge crane suitable for copper refineries:
Main lifting capacity: 20 tons
Auxiliary lifting capacity: 5 tons
20+5 ton bridge crane span: Customized according to the refinery's building gauge (e.g., 22.5m, 25.5m, 28.5m, etc.)
Overhead Bridge Crane Working class: A6 (heavy-duty) or higher (e.g., A7). Due to the handling of molten metal (anode copper, electrolytic residues, etc.), the strictest standards must be followed.
Lifting height: Main/auxiliary hooks are set according to the purchaser's requirements (e.g., main hook 18m, auxiliary hook 20m).
overhead crane Operating environment: High temperature (ambient temperature near the furnace area can reach 50-80°C), multi-metal dust, possible acid mist (electrolysis workshop), high humidity.
Control method: Dual control system of cab + ground remote control (IP65) ensures safety and flexibility.
Bridge cranes (EOT crane) for copper plants
Weihua Group provides specially adapted bridge cranes (EOT Crane) for different process stages in copper refining plant.
Bridge Cranes (EOT Crane) in the Anode Furnace/Casting Area:
Core Task: Lifting high-temperature anode copper molds and copper ladles (requires specialized lifting equipment).
overhead crane Requirements: Highest heat resistance, stability, and safety. The crane lifting equipment may require a water-cooled design.
Bridge Cranes (EOT Crane) for Electrolysis Workshop:
Core Task: Lifting anode plates, starting plates, and cathode copper plate bundles.
Overhead Bridge Crane Requirements: Extremely high positioning accuracy (within ±5mm) for easy plate hanging/removal. Protection against acid mist corrosion is required. Specialized lifting equipment (such as anode plate lifting equipment and cathode lifting equipment) is commonly used.
Bridge Crane (EOT Crane) in the copper plant's material transfer area:
Core tasks: Loading and unloading copper concentrate, matte, flux, waste anodes, etc.
Overhead Bridge Crane requirements: The bridge crane can be equipped with electromagnetic chucks or grab buckets (but the main parameters need to be adjusted according to the actual tonnage).
Price of 20+5 ton EOT crane (bridge cranes) suitable for copper refineries
As "special equipment" and "metallurgical cranes," the price of 20+5 ton EOT crane (bridge cranes) for copper refineries is affected by various parameters, such as the crane span and lifting height. Furthermore, the working environment and customized procurement needs of 20+5 ton bridge cranes used in copper refineries may also influence the price. EOT crane purchasers should choose manufacturers with mature experience and qualifications in metallurgical crane manufacturing. China Weihua Crane Group is a leading metallurgical crane manufacturer in China, possessing extensive experience in metallurgical crane manufacturing and exporting to over 170 countries and regions. If you have procurement needs for 20+5 ton bridge cranes for copper refineries, please contact Weihua Crane Group for price and high-quality 20+5 ton bridge cranes.
