There is a common misconception in material handling: if a pallet jack is used indoors, it automatically needs traditional polyurethane (poly) wheels. That is not always the whole story. The correct material depends on travel speed, load capacity, travel distance, warehouse environment, and floor condition.
Key Considerations for Indoor Warehousing
- Floor conditions: smooth concrete or epoxy floors where non-marking, floor-protecting performance is essential.
- Environment: noise-sensitive retail, hospital, office, or mixed-use areas operating in dry, room-temperature conditions.
- Speed and load: maximum loads around 5,000 lbs at operating speeds below 3.6 mph.
- Duty cycle: travel distance, shift frequency, turns, thresholds, and debris all affect wear and rolling effort.
When Traditional Polyurethane Works Best
If the application matches those conditions, traditional polyurethane wheels are an excellent fit. They protect finished floors, provide manageable rolling resistance, and keep manual pulling effort relatively low.
What Changes in Damp Environments
Moisture changes the selection. Traditional cast-iron-core poly wheels can rust quickly, while repeated water exposure can accelerate polyurethane hydrolysis, delamination, and chunking. This shortens service life and increases maintenance.
Polyurethane on aluminum cores is a useful middle ground when quiet travel and corrosion resistance are both important. Rubber on aluminum cores adds grip and slip resistance on wet surfaces, although its higher rolling resistance requires more manual effort.
The Tread Profile Matters
Wheel treads are commonly flat or crowned. In tight spaces with frequent turns, a crowned tread reduces the contact area and turning resistance, helping reduce operator fatigue.
