Handling of Over Dimensional Cargo (ODC) involves special planning, equipment, and logistics due to the size, weight, and nature of the cargo. ODC refers to cargo that exceeds the standard legal dimensions for road, rail, or sea transportation, either in length, width, height, or weight.
🔧 What is Over Dimensional Cargo?
ODC (Over Dimensional Cargo) is any cargo that exceeds the standard dimensions of a container or transport vehicle. Common examples include:
- Wind turbine blades
- Industrial boilers
- Construction machinery
- Large transformers
- Plant components
🚛 Key Steps in Handling ODC:
1. Detailed Planning & Route Survey
- Conduct route surveys to check for physical obstructions like bridges, tunnels, and overhead wires.
- Identify alternative routes if certain areas cannot accommodate the cargo.
2. Permits and Approvals
- Obtain necessary permits for over-dimensional transport from relevant government authorities (e.g., road transport departments, railways, or ports).
- Comply with regulations related to speed limits, escort vehicles, and travel timing (often nighttime or low-traffic hours).
3. Specialized Equipment
- Use equipment like:
- Low bed trailers
- Multi-axle trailers
- Modular hydraulic trailers
- Cranes and jacking systems
4. Loading and Securing
- Use cranes or hydraulic lifts for safe loading.
- Apply customized lashing, bracing, and securing methods to prevent movement or damage during transport.
5. Escort and Safety Measures
- Employ escort vehicles (pilot cars) to guide and warn other road users.
- Use flags, lights, and signage to increase visibility.
- Monitor for weather and road conditions.
6. Coordination with Authorities
- Regular coordination with traffic police, highway authorities, and port officials is essential.
- Notify stakeholders of arrival/departure to minimize delays.
⚠️ Challenges in Handling ODC
- Infrastructure limitations (narrow roads, low bridges)
- Permit delays
- High transportation cost
- Damage risks during handling
- Weather constraints
🏭 Industries Commonly Using ODC Logistics
- Oil & Gas
- Power & Energy
- Construction
- Mining
- Aerospace
- Manufacturing
✅ Best Practices
- Use 3D route simulations and GPS tracking.
- Conduct risk assessments before transit.
- Work with experienced logistics providers.
- Maintain insurance for high-value cargo.
