Key SpecificationProject Background
Client: Coastal container terminal operator in South Africa.
Core challenges:
The cost of manually handling containers ranging from 20 to 45 feet in length is extremely high, with an average handling time of 22 minutes each time. Currently, our existing cranes will overwork or have inaccurate positioning when handling special loads. Therefore, the growing demand (a 35% year-on-year increase) exceeds the production capacity of our existing cranes.
Solution Objective:
Install a 40.5T Rail-Mounted Gantry Crane (RMG) with ISO-container-specific features:
| Key Specification | Value | Purpose |
| Lifting Capacity | 40.5 tons | Handles 20ft/40ft/45ft containers + tanks |
| Span | 30 meters | Covers 4 rail tracks + truck lanes |
| Lifting Height | 18.2 meters | Stacks containers 5-high safely |
| Lifting Mechanism | Spreader Beam | Auto-locks ISO twistlocks in 8 sec |
| Power Supply | 380V/50Hz/3Ph | Standard industrial supply |
| Operating Temperature | -20°C to +40°C | uitable for coastal climates |
Sinoko Crane Features: Precision & Power for Containers
A. Intelligent Container Handling
Spreaders:
Hydraulic telescopic beam adjusts to 20ft/40ft/45ft containers instantly.
Sensors detect container weight distribution (stops overload).
Anti-Sway Technology:
GPS-guided trolley reduces swing by 90% (critical in windy ports).
B. Rugged All-Weather Design
High-Torque Hoists:
3x 15kW motors lift 25 m/min at 100% capacity (-20°C cold start capability).
Corrosion Defense:
Sandblasted steel + epoxy coating resists saltwater spray (IP66 rating).
C. Operator-Centric Control
Ergonomic Cabin:
Air-conditioned, 360° visibility, shock-absorbing seats.
Dual Control Modes:
Cabin + remote control (range: 150m).
Implementation: From Rails to Reality
Starting from receiving the customer's inquiry, Sinokocrane immediately designs a solution for the customer. It also dispatches engineers to the customer's project site for on-site coordination. After the installation is completed, it conducts training for the customer's employees on the use of the crane.
Phase 1: Infrastructure (4 Weeks)
Laid 200m dual rails (P43 steel) with laser-aligned flatness (±2mm tolerance).
Installed substation for uninterrupted power (backup generators on-site).
Phase 2: Crane Assembly & Testing (3 Weeks)
Key Tests:
120% Load Test: 48.6 tons lifted with ≤5mm deflection.
Wind Resilience: Stable at Beaufort Scale 6 (45 km/h winds).
Spreader Calibration: 20-cycle twistlock test (0 failures).
Operator Training:
Simulator-based modules for collision avoidance + emergency drills.
Project Outcomes
Sinokocrane always keeps in touch with the clients even after the project is completed, asking about their usage. This client has provided us with the following genuine feedback.
Operational Transformation:
| Metric | Before | After | Improvement |
| Transfer time/container | 22 min | 7 min | 68% faster |
| Daily throughput | 160 TEU | 400 TEU | +150% |
| Accident rate | 7/yr | 0 | 100% safer |
| Energy use/container | 9.8 kWh | 5.2 kWh | 47% savings |
Strategic Benefits:
ROI: Achieved in 11 months via labor/fuel savings.
Space Efficiency: 30m span eliminated relocating containers between cranes.
Uptime: 98.6% (vs. industry 89%) with predictive maintenance sensors.
Expanding Applications
| Industry | Application | Why It Fits |
| Intermodal Rail Hubs | Transfer between trains/trucks | 30m span covers multiple rail tracks |
| Heavy Cargo Ports | Hydraulic tanks, project cargo | 40.5T capacity + spreader stability |
| Warehouse Integration | Container stacking/storage | 18.2m height enables high-density storage |
| Wind Energy Logistics | Turbine component handling | Subzero cold-start capability (-20°C) |
