Overhead Crane System for Copper Electrorefining & Electrowinning Plants
The Overhead Crane System is a purpose-designed material handling solution for copper electrorefining and electrowinning tankhouses. Engineered for continuous industrial duty under acidic and high-humidity environments, the crane integrates precision positioning, dual-hoist configuration and automation-ready control systems to support full-cell anode and cathode handling.
How Overhead Crane Works
Typical Configuration (Based on 24T + 5T System)
- Main Hoist Capacity: 24 tons
- Auxiliary Hoist Capacity: 5 tons
- Span: Customized (e.g., 30.46 m)
- Lifting Height: 10.2 m (adjustable per tank depth)
- Working Class: A7 / FEM M7
- Control Mode: Full automatic / Semi-automatic / Remote
- Positioning Accuracy: ±2 mm (fine positioning)
Designed for Copper Tankhouse Conditions
The crane is engineered specifically for:
-
Sulfuric acid mist atmosphere
-
High humidity indoor environment
-
0–48 kA DC electromagnetic interference
-
Continuous 16 h/day operation, 350 days/year
-
Seismic fortification intensity up to Grade 8
Anti-corrosion protection includes:
-
Zinc chromate primer + epoxy topcoat
-
Minimum 220 μm coating thickness
-
Full insulation design (≥2 MΩ)
-
Online insulation monitoring
Key Engineering Features
1. Dual-Hoist Design (24T/5T)
-
Full cell cathode lifting (up to 48 plates)
-
Full cell anode lifting (up to 47 plates)
-
Auxiliary hook for maintenance and auxiliary lifting
Maximizes operational flexibility and uptime.
2. Precision Laser Positioning System
- Dual laser positioning on long travel
- Laser positioning on trolley travel
- Positioning cone for final mechanical alignment
3. Variable Frequency Drive (VFD) System
- Hoist: 0–16 m/min (dual brake system)
- Trolley travel: 0–45 m/min
- Long travel: 0–180 m/min
Smooth acceleration reduces load swing and protects cathode surface quality.
4. Dedicated Electrolysis Spreader System
Includes:
- Anti-sway frame
- Drip tray
- Movable guide frame
- Combined hanger
- Insulated structure
Ensures safe lifting of full electrode groups without product damage.
5. Automation Integration
- PLC control system
- PROFINET interface
- Industrial Ethernet
- SCADA integration ready
- Remote wireless operation
Supports EPC-level plant automation integration.
Scope of Supply
- Crane bridge and trolley
- Main & auxiliary hoist system
