3 Considerations When Using Heavy Duty Industrial Casters Outdoors
Although Industrial casters are generally designed for indoor use, many casters can be used in outdoor applications when the need arises. When choosing casters for use outdoors, corrosion, deterioration, and ground conditions are some of the factors that will influence your purchase decision. Here are a few things to consider:
Moisture Damage and Ultraviolet Light
Water, humidity, snow, and other sources of moisture can cause considerable damage to casters. If your equipment remains outside under all weather conditions, and therefore all temperature fluctuations, you want to choose casters that will not corrode or deteriorate. Modern Suspension’s line of corrosion-resistant, aluminum casters is ideal for these conditions.
Sunlight can also be harsh on plastics and other materials. Special UV inhibitors can be added to plastic resin compounds that are nearly impervious to sun damage or deteriorate from high temperatures. This is where stainless steel or polyurethane is a good choice.
Outdoor Surface Condition Factors
When choosing industrial casters for outdoor use, different surface conditions also help dictate what wheel material and type to choose. All outdoor surfaces are not created equal, and they tend to be much harsher than indoors. Rocks, cracks, uneven surfaces, and other blemishes that are common in cement and asphalt can stop a cart from rolling.
A spring-loaded, shock-absorbing caster is ideal for outdoor use. The springs allow the wheels to roll over obstructions and provide a means to dissipate any shock caused by the impact of the wheel with the obstacle.
Another option is to use Pneumatic Tires, which offer the “give” needed to roll over small objects like gravel or even cracked cement. They also perform on grass, although these are not preferred surfaces for casters. They are also suitable for soft surfaces like sand because their larger footprints help to stop the wheel from sinking.
Many outdoor applications involve the use of a Tugger, tractor, or other powered mechanisms. These often travel at speeds that exceed the average walking speed of 3.1 mph. While transport speed generally has little impact on the swivel section, the design and material make up of the wheel is critical to knowing the expected speed utilized by these casters. TWERGO MAXX Ergonomic wheels are great for AGV’s and Tuggers. They are reliable at higher speeds and are available in two-and three-wheel configurations.
