Project Background
Client: Leading sugar processing plant in Mombasa, Kenya.
Challenge:
Outdated cranes caused frequent downtime during machinery maintenance.
Existing equipment lacked precision control for positioning sugar crystallizers (+/- 30cm error).
Low factory headroom (12m max) demanded ultra-compact cranes.
Solution:
Supplied 3 units of 5T European Single Girder Cranes with intelligent motion control.
| Parameter | Specification | Client Benefit |
| Capacity | 5 tons | Handles press rollers, gearboxes |
| Span | 5 meters | Fits narrow processing lanes |
| Lifting Height | 11 meters | Clears tall refinery equipment |
| Hoist | 5T Electric Chain Hoist | Smooth sugar bag palletizing |
| Power | 380V/50Hz/3Phase | Matches Kenyan industrial voltage |
Sinoko Crane Features: European Engineering Excellence
A. Advanced Motion Control
VF Drive Precision:±5mm positioning accuracy for delicate sugar machinery.
Soft Start/Stop:Eliminated material spillage during bag transfers.
B. Premium EU Components
Unified Drive System:ABM/Nord SEW triplex gearmotors (motor+gearbox+brake) → 30% fewer failure points.
Durability Upgrades:
Galvanized steel ropes (resist sugar dust corrosion)
Self-adjusting disc brakes
Programmable limit switches (±1cm height control)
C. Space-Optimized Design
Low Headroom Profile:150mm lower than standard cranes → cleared 11m ceiling with 500mm safety margin.
Lightweight Girder:High-strength steel reduced structural load → no column reinforcements needed.
Implementation: Zero-Disruption Deployment
Phase 1: Site Adaptation (1 Week)
Scanned facility with 3D LiDAR → confirmed 0 clashes with pipes/conveyors.
Pre-assembled cranes offsite → minimized installation downtime.
Phase 2: Installation & Training (10 Days)
Power Resilience:Installed voltage stabilizers (handled ±15% grid fluctuations).
Operator Training:
Focused on VF drive fine-tuning for fragile loads
Swahili subtitled AR maintenance guides via QR codes
Phase 3: Validation Testing
125% load test (6.25T) → ≤3mm girder deflection.
Emergency stop at full speed → ≤300mm drift (EN 15011 compliant).
Results: Transforming Sugar Production
Operational Impact:
| Metric | Before | After | Improvement |
| Maintenance Time | 8 hrs/task | 2.5 hrs/task | 69% faster |
| Positioning Error | ±30cm | ±5mm | 98% more accurate |
| Sugar Bag Damage | 5% | 0.2% | 24x reduction |
| Energy Consumption | 11 kW/h | 7 kW/h | 36% savings |
Strategic Gains:
ROI Achieved: 14 months via reduced sugar waste.
Downtime Avoidance: Saved $65,000/month in lost production.
Future Scaling: Client ordered 2 more cranes for new refinery lines.
Applications Across Sugar Processing
① Centrifuge Maintenance
VF drive enables micrometer adjustments of rotating drums.
Galvanized ropes withstand acidic syrup vapors.
② Bagging Line Support
Transfers 1-ton sugar bags to pallets with zero spillage.
Low headroom design fits above conveyor belts.
③ Boiler Room Service
Compact crane services valves/pumps in tight spaces.
IP55-rated components resist steam/humidity.
