Project Background
Client: Leading logistics terminal operator in Karachi Port, Pakistan.
Challenge:
Outdated gantry cranes caused frequent downtime during container handling, with average transfer delays of 45 minutes/day.
High maintenance costs (up to $18,000/year) due to obsolete mechanical systems.
Limited yard space demanded a compact, high-precision crane to navigate narrow aisles (max. clearance: 12m).
Solution:
Supplied 1 unit of Sinoko 10T European Gantry Crane with dual-speed hoist and adaptive control.
Characteristics:
Capacity:10 tons,Handles ISO containers efficiently.
Span:11.43 meters,Fits constrained port layouts.
Lifting Height:5 meters,Optimal for truck loading/unloading.
Hoist:10T European Electric Hoist,Dual-speed (0.8/8 m/min) for precision positioning.
Power:415V/50Hz/3Phase AC,Compatible with Pakistani grid.
Sinoko Gantry Crane Features: European Engineering Excellence
A. Space-Optimized Design
Compact Structure: 15% lighter than conventional models, reducing foundation reinforcement costs by $7,200.
Low Headroom Profile: 5m lifting height within 6m building clearance, maximizing vertical space utilization.
B. Advanced Motion Control
Dual-Speed Hoist:
Precision Mode (0.8 m/min): ±10mm accuracy for container locking pin alignment.
High-Speed Mode (8 m/min): Rapid transfer of 25 containers/hour.
Intelligent Braking: Self-adjusting disc brakes + overload limiter, eliminating cargo sway.
C. Durable EU-Components
Triple-Certified Gearmotor: ABM/Nord/SEW integrated unit (IP55-rated) resisting saltwater corrosion.
Galvanized Components:Wire ropes, bolts, and joints withstand Karachi’s humid coastal climate.
Programmable Safety Systems:
Automatic travel limit switches.
Emergency stop with <300mm drift distance (ISO 12485 compliant).
Implementation: Seamless Deployment
Phase 1: Site-Specific Engineering
3D Laser Scanning: Mapped terminal obstacles (pipes, lighting poles) to optimize rail alignment.
Localized Power Adaptation: Installed voltage stabilizers to handle ±10% grid fluctuations.
Phase 2: Installation & Training (12 Days)
Modular Assembly: Pre-assembled girder sections reduced on-site work by 40%.
Operator Training:
Urdu-language VR simulations for dual-speed operation.
Maintenance workshops focusing on bolt torque checks and brake calibration.
Phase 3: Compliance Validation
Load Testing: 125% (12.5T) static/dynamic tests with ≤5mm girder deflection.
Port Authority Certification: Met PNAC-Pakistan National Accreditation Council standards.
Results: Operational Transformation
Quantifiable Gains:
Metric | Before | After | Improvement |
Container Throughput | 18/hr | 25/hr | 39% increase |
Energy Consumption | 15 kW/h | 9 kW/h | 40% savings |
Maintenance Costs | $18,000/yr | $6,500/yr | 64% reduction |
Strategic Impact:
ROI Achieved: 11 months via reduced fuel waste and labor delays.
Downtime Elimination: Zero crane-related delays in 6 months post-installation.
Client Expansion: Subsequent order for 2 additional cranes for Gwadar Port terminal.
Application Domains
① Port Container Handling
Dual-speed hoist enables seamless transition between ship-to-shore and truck loading.
Corrosion-resistant materials extend lifespan in coastal environments.
② Warehouse Logistics
Compact span (11.43m) navigates tight storage aisles.
Precision mode assists fragile cargo (e.g., medical equipment) placement.
③ Manufacturing Plants
Low headroom design fits low-ceiling facilities (e.g., automotive parts assembly).
415V/50Hz compatibility integrates with Pakistani industrial power networks.
