Project Background
Client: Leading textile manufacturer in Addis Ababa, Ethiopia.
Challenge:
Manual handling of fabric rolls (3–4.5T) caused 15% material damage and bottlenecks (max. 80 rolls/hour).
Low factory headroom (10m) restricted crane installation options.
Voltage fluctuations (360–420V) disrupted existing equipment.
Solution:
Deployed Sinoko’s 5T LDA Single Beam Overhead Crane with custom adaptations:
| Parameter | Value | Rationale |
| Capacity | 5 tons | Handles oversized fabric rolls |
| Span | 22.5 m | Covers weaving + storage zones |
| Lifting Height | 9 m | Clears 8m-high dyeing machines |
| Hoist | CD1 wire rope hoist | Dual-speed (8/0.8 m/min) control |
| Duty Class | A4 (medium duty) | 150 cycles/day capability |
| Power | 380V/50Hz + stabilizer | Adapts to Ethiopian grid instability |
Key Features of Sinoko LDA Crane
A. Precision Engineering
European FEM Standards: Certified for smooth operation (ISO 12485, DIN 15018).
Dual-Speed Hoist:
Precision Mode (0.8 m/min): ±10mm fabric roll positioning.
High-Speed Mode (8 m/min): Rapid transfer between stations.
B. Space-Saving Design
Compact Girder Profile: 450mm height fits 10m-low factories.
Lightweight design: 30% lighter than those of competitors' cranes, and no need to reinforce the structure.
C. Industrial-Grade Reliability
Siemens Controls: IP54-rated components resist dust and humidity.
Auto-Safety Systems: Overload limiter+ dual limit switches.
Low-Noise Operation: ≤65 dB for textile-sensitive environments.
Implementation Process
Phase 1: Site Adaptation (2 Weeks)
Structural Survey: Laser-mapped columns to optimize runway beam placement.
Grid Stabilization:Installed voltage regulators at substations.
Phase 2: Installation & Commissioning
Modular Assembly: Pre-assembled girder sections installed in 3 days.
Load Testing:
125% capacity test (6.25T) with ≤3mm deflection.
Emergency stop response: <2 seconds at full speed.
Operator Training:
Amharic-language VR simulations for roll-handling protocols.
Maintenance workshops for daily inspections.
Project Outcomes
Operational Improvements
| Metric | Pre-Install | Post-Install | Gain |
| Fabric Rolls Handled | 80/hour | 120/hour | +50% |
| Material Damage | 15% | 0% | 100% reduction |
| Energy Consumption | 12 kWh/hour | 7 kWh/hour | 42% savings |
| Downtime | 8 hours/week | 0.5 hours/week | 94% less |
Strategic Benefits:
ROI: 14 months via reduced waste and labor costs.
Safety: Zero accidents in 6 months (Ethiopian OSHA compliant).
Scalability: Client ordered 2 more cranes for new production lines.
Application Areas
Textile Manufacturing Workflow:
Dyeing Section: Precision placement of wet fabric rolls.
Weaving Zone: High-speed transfer of raw material spools.
Warehousing: Stacking finished rolls (9m height utilization).
Cross-Industry Adaptability:
| Sector | Use Case | Technical Edge |
| Automotive | Engine block assembly | ±10mm positioning accuracy |
| Food Processing | Silo ingredient handling | Hygienic enclosed hoist design |
| Warehousing | Pallet loading | 22.5m span covers 5,000m² floors |
| Paper Mills | Paper roll transfers | Anti-slip hoist control for delicate surfaces |
