Advantages and Limitations of Small Spring-Loaded Casters

In this article, we’ll discuss the importance of shock-absorbing and impact loading, how to choose the right size and type of spring-loaded caster, and the limitations of these casters.

High-impact loading

When using small spring-loaded casters, it is important to consider the amount of force that the caster will exert. When the force is too large, the small spring loaded casters may not be able to withstand the weight and may end up crashing. If the force is too small, the caster may experience too much vibration and damage the payload. A balance between high and low impact is necessary to avoid damage to the caster and payload.

In general, casters come in three sizes, depending on their size. The light-duty model is suitable for loading up to 500 pounds. The medium-duty model is suited for loads between 500 and 2,000 lbs. The heavy-duty version is for loads over 2,000 lbs. There are two types of casters: light duty and medium duty. Light duty casters are best suited for moving small objects, while medium-duty and heavy-duty casters are appropriate for heavier loads.

Shock absorbing

Shock-absorbing small spring-loaded casters are an excellent choice for smaller loads. These casters are designed with high-strength chrome-vanadium springs to minimize yielding and maximize durability. The spring-loaded casters begin compressing at about 25 pounds per caster, which results in quieter empty returns. In addition, the long swivel lead minimizes excessive shimmy when towing. Applications for shock-absorbing casters include aircraft jacks, jet engine dollies, trash gondolas, lift truck stabilizers, parade floats, revolving signs, and garbage trucks.

The benefits of shock-absorbing casters are numerous. They protect cargo, help reduce noise, and rollover some obstructions. However, choosing the wrong type of spring-loaded caster may negate all benefits and reduce performance below that of conventional casters. Therefore, the first important step is choosing the right spring-loaded casters for your specific needs. The springs should be designed to accommodate the weight of your load and have the proper spring constant.

Pre-load of the spring

The spring’s pre-load on small, spring-loaded casters will determine the maximum amount of movement that the casters can achieve. Ideally, the spring will operate within a range resembling a theoretical deflection curve. In other words, each pound of applied force causes the spring to deflect by the same amount.

The spring should be pre-loaded to a certain degree for the casters to be effective. If the spring has no pre-load, it requires approximately 2000 pounds of force to move an inch. When the spring has some pre-load, it will have slightly lower resistance and will not restrict the caster’s movement. However, this may not be enough in some cases. In addition, excessive pre-load could cause the damper to be stressed.

The pre-load of small spring-loaded casters should be carefully selected. It should have an initial force equivalent to 250 lbs. As the load increases, the spring deflects, reducing the amount of noise generated by the caster. The lower the pre-load, the less deflection will occur. A good spring configuration will also prevent excessive noise during production.

Limitations of spring-loaded casters

When it comes to choosing the right caster for your application, there are some basic considerations that you should consider. Spring-loaded small casters should be able to deflect and roll with the predictable force for the entire length of the graph. If the caster isn’t spring-loaded correctly, the caster’s movement will be unpredictable and may lead to damage to the cart and payload.

Environmental conditions also have an impact on the performance of small spring-loaded casters. For example, if the cart is frequently subjected to excessive heat, its caster components can be damaged. Casters that are not made from stainless steel may corrode in a wet environment, weakening them and increasing their risk of failure. Other environmental factors to consider are surface characteristics and the presence of debris or other contaminants.
