How To Pick Heavy Duty Casters

By Mattie Knight


Productivity of equipment and the workers who use them is highly affected by wheels and casters installed. When the right heavy duty casters are selected, long term cost and productivity are maximized while earning the greatest return on investment. With that in mind, it is important to invest some time and resources in picking these devices. This article will present some important facts to consider before settling down on any kind or model.

The first factor to consider must be the expected load per caster. For safe application the load per caster needs to be exceeded by around thirty percent. Weight per caster is usually calculated by dividing maximum weight by total number of casters less one or two. Not all wheels bear the weight at any given time because floors are expected to be irregular. Hence the subtraction.

The next item of consideration is speed. Devices can only move at a given speed when supporting certain amounts of weight and failure to adhere to that causes damage. It is advisable to consider the worst case scenarios when calculating so as to account for possible discrepancies. Manufacturers can help with calculations for speed because they have systems for duplicating applications.

The floor condition should be considered next. Newly cemented or other types of floors offer a very good surface for the wheels to move without trouble. However, if the floors have holes and other kinds of defects, they can cause some real damage within a short time if the casters selected are of the wrong type. If the floors have defects, one should consider high-rise wheels.

Wheels also damage floors. Running metallic casters over wooden or ceramic floors damages them. It is better to buy devices with softer wheels if one wants to preserve softer floors. Many companies produce soft wheels made out of plastic and other softer materials.

Wheel movement varies among models. There are two main types of movement, that is, unidirectional and multidirectional. Unidirectional devices maintain a straight course during movement, while multidirectional ones can rotate through 360 degrees and move into any direction. How the caster is attached to the vehicle also differ. Some use screw-ons or plates while others use stems. Mode of movement is supported by method of attachment. One must be straight with their facts and requirements before buying casters.

Today, as a result of better technology, there are two modes of driving casters. Some are manually driven while others are driven by power. More force is applied on the wheels of power driven models by the weight they are supporting even though they move faster. On the other hand, manually driven models move slowly but reduce force exerted on the wheels. With lower force exertion, wheels last longer.

Finally, one should consider the features incorporated to the device. Some of the most common features include locks, anti-bacterial material, and shock absorbency. Locks are important for controlling free movement of the equipment the wheels are attached onto. Additionally, when used in homes, locks are useful in keeping pets and children safe.
