The specifications that are provided by manufacturers of plastic pallets are based on an evenly distributed load that covers the entire deck of the pallet. If this is the type of load that you are putting on the pallet, you should be able to safely place the specified weight on the pallet. However, there are some unit loads that can cause the specified load capacity to decrease.
- Placing product that only sits in the pallet center (like a metal coil) and does not extend over the outer legs to the edge of the deck. This can force the center of the pallet down and the edges up which will greatly reduce the unsupported racking capacity.
- Stacking boxes in single columns on a pallet can create many different pressure points and reduced load stability. If this type of load is not properly stretch wrapped or strapped, the columns can spread out and cause the edges of the pallet to deflect downward. This is called flowering as the stacks of boxes can spread out like a flower. A brick stack of boxes on top of a pallet is a better option as it creates more load stability and less pressure points.
- Placing 50 lb. bags filled with product such as powdered or pelletized materials on their sides on a pallet can be a very difficult load. The material in these types of bags will continue to shift and, when double stacking, the multiple layers of bags can cause bending of the pallet if there is not adequate support underneath it.
As you can see, determining the correct weight capacity for your specific unit load on a pallet can sometimes seem like a moving target. For help in determining which pallet matches up correctly with your unit load and handling environment, contact one of the pallet experts at The Nelson Company.
