Ergonomic considerations are always top of mind. As the U.S. workforce ages and workmen's compensation costs climb, selecting a wheel with high rollability is a smart choice to reduce stress on joints, prevent back injuries, and better accommodate staff. Wheel size is the single biggest factor in rollability. Larger wheels are easier to push or pull under load. Test data is available to determine what size and tread type is best for any given load and ergonomic parameters.
Be sure to add the weight of the cart, trailer, or AGV in addition to the weight of the load. Also consider the possibility of overload, shock loading, abuse or poor floor conditions into your calculation. Then it may seem obvious to divide the maximum load weight by four wheels, but this can lead to heavy miscalculations. Why? Because most loads don't maintain an even weight across the length and width of the vehicle. An off-center load could overload even the most durable wheels.
Shock loading occurs when a load is dropped onto the trailer. Or when a rig rolls over a bump, like a concrete joint, door jam, dock plate or leveler. In some cases, shock loading can force a wheel to bear more than three times the weight of the load.
Where is it rolling? Environmental conditions must be considered when choosing a wheel. For example, if excessive noise is an issue, Hamilton offers quiet-rolling wheels with high load capacities. Extremely hot or cold applications may require special wheel materials, and bearing lubricants, to withstand the conditions.
Abuse takes a toll on wheels. We like to believe that everyone uses them as intended, but we also understand that's not always the reality. Sometimes workers move too quickly, take short cuts, or even take out frustrations on them. Keep this in mind when selecting equipment.
Poor floor conditions can cause a wheel to fail, but don't underestimate the effect wheels can have on floors, too. Very hard wheels, such as cast iron or forged steel, roll easily and carry higher capacities than resilient tread wheels. But, they can damage concrete floors and lead to costly repairs.
