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 factor is the speed. Manufacturers have designed the devices to be used at different speeds when carrying certain amount of weight. This speed must never be exceeded. When doing calculations, one should always consider the worst case scenario so that they account for discrepancies. Manufacturers can help with duplicating the application to reach at the right figures.

One should consider the condition the floor is in next. Wheels run best on flat floors. Presence of defects makes movement hard and cause damage to the wheels. In such conditions, the wheels may survive longer if they are of the right size. Otherwise, they can get damaged very first. High-rising wheels are the best choice for floors that are highly irregular and have defects.

Floors also get damaged by wheels. Floors made of wood or ceramic get damaged by wheels during movement. To preserve floors like those ones, softer wheels should be bought. Some examples of soft materials used to make soft wheels include plastic and rubber.

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, technology has made it possible to produce models that are power driven and manual driven. Power driven models experience more force from the load, but also move faster. On the other hand, manual ones move slowly at the pace of the worker, but experience less force. Less force implies that longevity is increased.

Finally, there are many features that modern devices incorporate that should be considered. Presence of shock absorbency, anti-bacterial material, and locks are among top features people consider. Locks ensure that the vehicle remains pinned in a given position. They also make homes safe for pets and children.
