Advantages and Considerations of Container Loading with Pallets

Loading goods into containers using pallets (i.e., placing goods on pallets first, then loading the entire pallet into the container) is a common standardized practice in logistics. Below are its advantages and key considerations:

I. Advantages

1. Improved Loading/Unloading Efficiency Palletized goods can be quickly moved using forklifts, pallet jacks, or other machinery, reducing manual labor and time. This is especially beneficial for bulk or heavy goods, significantly shortening container loading/unloading durations.

2. Enhanced Cargo Integrity Pallets provide stable support, minimizing damage from  or collisions during handling and transportation (particularly for boxed, bagged, or soft goods). They also prevent direct contact between goods and the container floor, reducing risks of moisture or contamination.

3. Facilitated Stacking and Space Utilization Palletized goods are neat and easy to stack in layers inside the container, allowing more efficient use of vertical space to increase loading rates. Stable stacking also reduces the likelihood of cargo shifting or collapsing during transit.

4. Standardized Operations for Supply Chain Compatibility Standard pallet sizes (e.g., 1.2m×1.0m) are well-matched with container dimensions and equipment like forklifts, enabling seamless integration across warehousing, transportation, and transshipment, thus lowering supply chain coordination costs.

5. Simplified Counting and Management Counting by pallet is more efficient than individual items, facilitating inventory management and logistics tracking (e.g., digital traceability via pallet labels).

II. Considerations

1. Pallet Specifications and Quality

   • Size Compatibility: Choose pallets matching container inner dimensions (e.g., 20ft, 40ft containers) to avoid issues like difficulty in loading or wasted space. For example, standard pallets should fit the number that can be placed side by side along the container’s width.
   • Load-Bearing Capacity: Pallets must withstand cargo weight and stacking pressure. Avoid material or structural defects (e.g., cracks, deformation) that could cause collapse, especially for multi-layer stacking.
   • Regulatory Compliance: For exported goods, ensure pallets meet quarantine requirements (e.g., wooden pallets need fumigation and IPPC marking to prevent customs delays).

2. Securing Goods on Pallets

   • Proper Stacking: Stack goods neatly on pallets with centered weight distribution to avoid imbalance, which could cause tilting, falling, or container instability during transit.
   • Reinforcement: Use stretch film, strapping, etc., to secure goods and pallets as a single unit, preventing shifting during . Fill gaps with cushioning materials (e.g., bubble wrap, cardboard) to reduce movement.

3. Loading Planning Inside the Container

   • Space Utilization: Design rational placement (e.g., horizontal, vertical, staggered stacking) based on pallet size and container volume to minimize gaps. Reserve ventilation space for goods requiring airflow.
   • Weight Distribution: Ensure total weight of palletized goods is evenly distributed on the container floor. Avoid local overloading (container floors typically have a limit of 2 tons per square meter under uniform distribution) to prevent damage.
   • Stacking Limits: For multi-layer pallet stacking, confirm that upper pallets do not exceed the load capacity of lower pallets and goods. The top of cargo should not exceed the container door header to avoid closing difficulties.

4. Protection for Special Goods

   • Moisture/Water Resistance: For moisture-sensitive goods, place moisture-proof boards under pallets and desiccants inside containers. For liquid goods, use leak-proof pallets.
   • Fragile/Valuable Goods: Add corner protectors, baffles, or reinforce with wooden crates around pallets to prevent  damage. Secure pallets to container lashing points with ropes if necessary.

5. Operational Safety

   • Forklift Operations: Ensure forklift tines are fully inserted into pallet pockets to prevent slipping. Operate slowly when stacking to avoid colliding with container walls.
   • Personnel Safety: Prohibit standing or walking under palletized goods to prevent injury from falling cargo.

 

By leveraging the standardization benefits of pallets and addressing these considerations, you can maximize the efficiency and safety of container transportation while minimizing logistics losses.
