Electrolytic multifunctional cranes are auxiliary equipment for large-scale pre-baked anodic aluminum electrolytic production.

   Multifunctional Crane for Electrolytic Aluminum is composed of feeding mechanism, slagging mechanism, the anode replace mechanism, shelling mechanism and aluminium discharging mechanism.

Product Overview: Multifunction Crane for Electrolytic Aluminum (20t-40t Capacity)

Our CLE & PTM Series Multifunction Cranes are heavy-duty double-girder, dual-trolley overhead cranes specifically engineered for electrolytic aluminum production facilities. Designed to handle 20 to 40 metric tons, these cranes optimize anode handling, molten aluminum operations, and electrolytic cell maintenance with precision and efficiency.

Key Features & Technical Specifications

1. Dual-Trolley System for Enhanced Productivity

• 32/5t + 32t trolleys enable synchronous lifting (e.g., anode beam lifting, cell superstructure installation).

• Multi-process coordination (e.g., simultaneous crust breaking & material feeding).

2. Elevated Main Girder Design

• Increased hook height for seamless aluminum ladle transfer to casting bays.

• Robust end-beam connections ensure structural rigidity and transportability.

3. Variable Frequency Drive (VFD) Control

• Smooth acceleration/deceleration prevents wheel slippage.

• Horizontal guide wheels minimize lateral drift during long-span travel.

4. High-Performance Hoisting Mechanism

• Hard-gear reducers maximize hook coverage.

• Dual braking system:

• Primary (high-speed) dual brakes + secondary (low-speed) safety brake (auto-engages during free-fall detection).

5. Insulated Double-Layer Trolley

• Electrical isolation between upper/lower trolleys prevents stray current risks.

• Optimized vertical clearance for overhead obstructions.

  
  

Operational Benefits

• Industry-Specific Design: Complies with FEM, ISO, and GB standards for aluminum smelting.

• Automation Compatibility: Integrates with smart plant systems (e.g., IoT-based load monitoring).

• Safety Redundancies: Insulated trolleys, anti-sway controls, and fail-safe brakes.

Case Study: A recent deployment of 6 CLE/PTM cranes reduced anode-change downtime by 30%, achieving 200+ daily cycles.

Multifunction crane for electrolytic aluminum can meet the environmental requirements and process requirements of high temperature molten salt, high current, strong magnetic field, dusty working site, and complete the process of prebaked anode aluminum operating.

Primary Applications in Aluminum Smelting

1. Anode Servicing

• Anode replacement: Precise positioning for spent/new anodes.

• Anode beam lifting: Dual-trolley synchronized lifting of heavy anode frames.

• Crust breaking (anode cover removal): Automated hammering to access molten metal.

2. Molten Aluminum Handling

• Metal tapping: Safe 20t-40t ladle transfer to casting stations.

• Slag skimming: Efficient removal of electrolytic cell waste.

3. Electrolytic Cell Maintenance

• Cell superstructure assembly/disassembly: Dual-trolley lifting of large components.

• Cell repair access: 360° maneuverability for maintenance crews.

4. Material Handling & Feeding

• Alumina powder feeding: Automated dispensing into electrolytic cells.

• Carbon block transport: Support for anode production lines.
