Weight Distribution Principles

Container Stability
Proper weight distribution is critical for container stability during ocean transport:

1. Center of Gravity: Should be within middle third of container length
2. Vertical CG: Keep as low as possible for stability
3. Lateral Balance: Distribute weight evenly side-to-side
4. Concentration Limits: Maximum 5 tons per square meter on standard floors

Loading Sequence
1. Heaviest Items First: Load heaviest equipment at container bottom
2. Progressive Weight: Lighter items on top and toward ends
3. Void Filling: Use blocking to eliminate void spaces
4. Final Balance: Verify overall weight distribution

Case Study: 200-Ton Press Container Loading

Step-by-Step Loading Process

Phase 1: Container Preparation (2 hours)
1. Inspection: Container structural integrity verified
2. Cleaning: Interior cleaned and dried
3. Marking: Loading position marked on floor
4. Lashing Points: All D-rings inspected and tested
5. Documentation: Pre-loading photos for insurance

Phase 2: Equipment Positioning (3 hours)
1. Crane Setup: 50-ton mobile crane positioned
2. Rigging: Press rigged with spreader bar system
3. Test Lift: Equipment lifted 300mm for rigging check
4. Container Alignment: Press aligned with container opening
5. Slow Entry: Equipment slowly moved into container

Phase 3: Securing (4 hours)
1. Positioning: Press positioned for optimal weight distribution
2. Chocking: Steel and timber chocks placed around base
3. Primary Securing: Eight Grade 70 chains (3/8" diameter)
4. Secondary Securing: Six polyester straps (10,000 lb WLL)
5. Void Filling: Blocking installed to prevent movement

Securing Methods and Materials

Primary Securing Systems
- Chains: Grade 70 or higher, minimum 3/8" diameter
- Working Load Limit: Calculate based on equipment weight and G-forces
- Angle Factors: Account for securing angle in calculations
- Hardware: Certified hooks, shackles, and tensioning devices

Secondary Securing Systems
- Polyester Straps: UV-resistant, high-strength webbing
- Ratchet Tensioners: Provide precise tension control
- Edge Protection: Prevent cutting at contact points
- Load Distribution: Spread loads across structure

Blocking and Chocking
- Timber Blocking: Hardwood lumber, minimum 4x4 inches
- Steel Chocks: Custom fabricated for specific equipment
- Rubber Pads: Vibration dampening and surface protection
- Void Filling: Prevent any movement during transport

International Shipping Considerations

Documentation Requirements
- Bill of Lading: Ocean freight contract
