Pallet maintenance 101: Extending the life of your wooden pallets

Wooden pallets are an essential part of warehouse and logistics operations. They sustain the movement and storage of goods down the supply chain. Although pallets represent one minor line item in operational costs, their regular maintenance can reduce the replacement cycle, leading to substantial savings. Maintaining a pallet fleet enhances efficiency and reduces risks in a warehouse and this article takes a look at how best to do this..

Conduct routine inspections

A routine inspection is generally the first step in properly maintaining pallets. It will help recognise damage or wear before it gets worse. Small cracks, splits, and loose nails can easily become major structural failures if left unfixed, risking product damage and injury to employees.

Design a routine to check your pallets. A standard approach is to check them whenever they have been delivered or just before stacking them in the facility. Educate employees on what issues to typically look for, such as:

• Cracked or splintered boards
• Loose or overhanging nails
• Broken stringers
• Split blocks

After inspection, pallets have to be separated into three categories. These include those for reuse directly, those that will be repaired, and those beyond repair. Of course, this means that only the usable ones will be in circulation, helping to reduce accidents as well as product damage due to unsafe pallets.

Techniques to solve daily problems

Implementing an in-house repair process can extend the life of wooden pallets, making them cost-effective. Some repair techniques businesses can follow are:

Board replacement: Boards with cracks or splinters are the most common issues for repair. Use matching timber to replace the boards by nailing or screwing in place. The boards should be of appropriate thickness when being replaced to maintain structural capability.

Stringer repair: Broken stringers may be repaired in the field by attaching support plates, or "doublers," to the area. This type of reinforcement will restore strength to the pallet without having to replace a full stringer. Alternatively, a "plug" could be used, in other words, inserting a new piece of wood into the broken area and securing it in place.

Nail reinforcement: Nails can become loose with changing product weights and continuous handling. Sand loose nails or replace them for added security against loosening. Use quality hardware for long-lasting repairs.

If repairs occur frequently in one spot it can significantly compromise the structure, it may simply be more practical to retire the pallet and replace it with a new or recycled one. The best practice is to set repair thresholds so as to save time and resources on items that are past their usable life.

Best practices for storage

The environmental storage conditions are of great importance to the quality of wooden pallets. They will drastically deteriorate in quality if exposed to moisture, extreme temperature conditions, and improper stacking.

Indoor storage: Pallets should be kept indoors as much as possible. Wet weather destroys them; it makes the wood swell and warp aside from weakening it. If it is not possible to store them indoors, then a tarp or covering must be used to protect them from the elements.

Proper stacking: Avoid stacking very high since they may easily warp or bend. If not stacked evenly, they could easily tip, causing damage and injury.

Ventilated storage areas: All storage areas should be properly ventilated to prevent moisture accumulation. A dry, well-ventilated environment will slow the rate of wood decay and not allow excess moisture in the wood.

Temperature control: Extreme cold and hot temperatures weaken the wood. Establish a controlled temperature in storage facilities and do not place them on very hot or cold or surfaces, such as concrete surfaces during winter.

Prevent infestation

Wooden pallets are prone to pest attacks, including the effects of termites, beetles, and moulds that may cause weakening of the structure. Measures to prevent infestation include:

Heat treatment: There are several pallet manufacturers that offer a heat-treatment service. This kills all pests harboured in the wood. Heat treatment helps prevent infestation and increases the integrity of the pallets.

Regular cleaning: Pallets must be frequently cleaned of debris or spilled substances that could attract pests. They must also be free of food residue or chemicals. Simple cleaning practices, such as hosing down with water or sweeping off debris, can keep pests away.

Chemical treatment: Chemicals can be used to protect against insect attacks, provided they are not hazardous and don't poison goods or contaminate the ground.

Maintenance program implementation

One of the best ways to manage a pallet fleet is by instituting a maintenance program. This helps standardise the process of inspecting, repairing, and replacing pallets and ensures that everyone on the team knows what they need to do to take care of them. Some of these program elements are:

Scheduled inspections: Schedule regular inspections based on usage frequency, like weekly, bi-weekly, or after every cycle.

Clear guidelines for necessary repairs: Define what types of repairs are acceptable and when a pallet should be replaced if it is too expensive to repair.

Staff training: Staff should be educated on the right method of handling pallets, such as lifting procedures and proper stacking. Less damage tends to be caused by trained employees.

Tracking and Inventory: A tracking system could be used to track each pallet's condition and life cycle. This information helps management replace and fix pallets as and when needed to achieve a better allocation of resources.

Routine inspections and repair processes combined with proper storage conditions can prevent pest infestations and extend the lifespan of wooden pallets. These strategies can make a meaningful difference in small and large-scale operations by reducing operational costs and increasing productivity.
