What are best practices for stacking pallets to maintain stability?

• A. Always stack pallets as high as possible to save space.
• B. Use pallets in good condition, center loads on pallets, keep stacks level and square, do not exceed height limits, and ensure adequate space for handling and shoring with wraps if needed.
• C. Place loads off-center to improve visibility.
• D. Skip wraps to reduce cost.

Answer: (B)

Maintaining pallet stability comes down to using undamaged pallets, distributing weight evenly, and keeping the stack neat, within height limits, and secured for transport. When pallets are in good condition, there are no cracked boards or broken stringers to fail under load, which reduces the chance of a sudden collapse. Centering loads on the pallet ensures the forklift can lift with a balanced center of gravity, minimizing tipping risk during lifting, moving, or braking. Keeping stacks level and square prevents leaning or skewing, which can cause a stack to shift or topple, especially when the forklift turns or encounters uneven flooring. Not exceeding the height limits is crucial because tall, top-heavy stacks are much more vulnerable to tipping, especially if the load shifts or the vehicle encounters a bump or corner. Providing adequate space for handling and applying restraints as needed—such as wrapping or other shoring—helps keep the layers from sliding relative to each other and maintains overall stability during movement and storage. Wrapping or other securement adds friction and restraint, which is essential when moving or storing loads that could shift. This is why stacking with wraps when required is part of best practice. In contrast, trying to save space by stacking as high as possible ignores stability and safety, placing loads at risk of tipping. Placing loads off-center to improve visibility undermines balance and can cause lateral instability. Skipping wraps eliminates a key stabilizing measure, increasing the chance of movement and spillage during handling.
