Project Background
Client: Leading copper rod manufacturer in Guayaquil, Ecuador
Challenge:
Manual coil handling caused 15% surface damage to Ø1.2m copper coils during transfers.
The existing lifting equipment of the client has deformed under the hot environment. The coil temperature is 80°C and it requires a significant amount of money for maintenance every month. Despite the increasing demand from the factory, the production output is still limited to 800 tons per month due to the slow production process.
Solution:
Custom-engineered Sinoko 30T C-Hook system for high-temperature copper coil handling.
Sinoko C-Hook Technical Highlights
A. Precision Copper-Coil Optimization
Thermal-Resistant Steel: High-tensile ASTM A572 steel (rated for 80–150°C), preventing hook deformation.
Adjustable Jaw System: Hydraulic width adjustment (1.0–1.5m) accommodates 3 coil sizes.
EdgeGuard™ Protection: Nylon-lined contact points eliminated coil scratches.
B. Safety & Efficiency Features
Anti-Slip Mechanism: Tungsten-carbide teeth + auto-locking latches secured coils during 12m lifts.
Dynamic Load Control: Embedded sensors restricted swing to <5° at 8m/min hoist speed.
Corrosion Defense: Hot-dip galvanized coating (150μm) resisted acidic copper oxide fumes.
C.Customized Specifications
| Parameter | Value | Client Benefit |
| Capacity | 30 tons | Handles jumbo copper coils |
| Max. Coil Temp | 150°C | Withstands hot rolling processes |
| Surface Treatment | Hot-dip galvanized | 10-year corrosion warranty |
| Safety Compliance | ISO 4309 / FEM 9.511 | Global operational certification |
Implementation Process
Phase 1: Coil-Site Adaptation (3 Weeks)
3D Laser Scanning: Mapped coil dimensions and furnace exit paths for collision-free lifts.
Material Testing: Validated steel integrity at 150°C in Sinoko lab (test report: SNK-CH-30T-ECU).
Phase 2: Installation & Training
Thermal Calibration: Adjusted jaw pressure for heat-expanded coils (±2mm grip tolerance).
Operator Training:
Spanish VR simulations for emergency coil-securing protocols.
Load-balancing drills using variable coil weights (20–30T).
Phase 3: Validation Testing
125% Load Test: 37.5T lift at 80°C with 0 permanent deformation.
Damage Validation: Zero surface defects after 50 transfer cycles.
Project Outcomes
Operational Improvements
| Metric | Pre-Install | Post-Install | Improvement |
| Coil Damage Rate | 15% | 0% | 100% reduction |
| Monthly Repair Costs | $12,000 | $1,800 | 85% savings |
| Production Throughput | 800 tons | 1,200 tons | 50% increase |
