A complete guide on buying caster wheels

Scaffolding is a temporary structure that allows access with weights at different heights. In several works, the entire structure needs to be reassessed in other locations at the same site. This is where caster wheels come into the picture. 

Scaffolding parts usually make the construction process easy, and caster wheels are one of those. From the construction industry to DIY projects, caster wheels help users access workstations with convenience.

But how do you know which scaffolding parts and accessories are the right choices? How do you know which caster wheels will give you more efficiency? How do you know which caster wheel will work on your site’s terrain?

Let’s get answers to the questions above in this article. 

Why does the choice of caster wheel matter?

There are multiple reasons why the choice of caster wheel is important.

1. Safety: The proper caster will roll over flooring and obstacles with just enough resistance to maintain control over the caster’s movement.

2. Ergonomics: Whether a cart weighs 1,000 or 10,000 pounds, if the incorrect caster is used, moving it from point A to point B can cause the operator significant strain.

3. Efficiency: A caster that rolls smoothly is an efficient caster. With the proper caster underneath your carts, equipment, machinery, etc., you will achieve maximum productivity and efficiency.

4. Protection: Your flooring is of equal value to the equipment and inventory that it transports. The appropriate caster will safeguard your flooring and reduce your long-term facility maintenance costs.

5. Saves time: Caster wheels can accelerate the movement of equipment and products within a facility, thereby reducing the amount of time manufacturers spend on product handling.

Pro-note: To help you determine what type of caster you require, ask these questions.

1. How much weight will these casters be required to support?

2. Is the work environment moist or greasy?

3. Is chemical or corrosive exposure a cause for concern?

4. What range of temperatures will the casters be exposed to?

5. What type of flooring or surface must you traverse?

6. Are aesthetics and noise reduction important factors?

7. Are brakes needed?

8. Will the wheels be used for propulsion?

What to consider while choosing caster wheels?

When searching for the ideal castor wheel for your particular use and application, there are a few primary considerations that must be made.

1. Proper load bearing capacity

You can determine the load capacity of each caster with the following formula:

C = (L+W)/n * SF

Where, 

C = required load capacity of a caster

L = maximum cart load

W = cart weight

n = the number of casters used

SF = safety factor

The safety factor is affected by speed and the ratio of wheel diameter to obstacle height, and consists of four categories:

• Indoor manual transport (obstacle height 5% of the wheel diameter): Safety factor: between 1.0 and 1.5
• Outdoor manual transport (obstacle height > 5% of the wheel ): 1.5 to 2.2 safety factor
• Indoor motorized transport (obstacle height 5% of the wheel diameter): Safety factor: between 1.4 and 2.0
• Outdoor motorized transport: 2.0 to 3.0 safety factor

Hence, choose a castor wheel with enough load capacity to support your application’s weight and any dynamic loads. Too-small castor wheels can fail and cause damage or injury. If you choose a castor wheel with a too-high load capacity, it may be too expensive and not perform well.

2. Select the type of tread material

Hardness, shape, and tread material affect operational comfort, smooth-rolling performance, and starting, rolling, and swivel resistance. The wheel tread or tire should be softer than the floor to prevent damage.

The floor a wheel runs on must withstand pressure, especially with heavy loads. Wood, tar, concrete, and electrically conductive floors require extra caution.

Here’s a guide for you.

3. Roll resistance

When a wheel rolls, there is always frictional resistance. The amount of resistance created by friction depends on the wheel’s material and the rolling surface. A rubber wheel, for instance, will have greater roll resistance than a plastic wheel. 

The surface type also influences roll resistance. A smooth concrete floor will provide less resistance than a path made of gravel. By considering roll resistance, you can ensure that your castor wheels provide the necessary level of support and stability.

4. Operating environment

It is essential to consider a variety of environmental factors. For instance, if you require a castor wheel that can withstand high temperatures, you will need to select a model that is constructed from heat-resistant materials. 

Choose a model with a large diameter and a wide tread if you require wheels that can traverse rough terrain without difficulty. And if you require a wheel that is resistant to damage from oils and liquids, you must select a model with a smooth, nonporous surface. By considering all of these factors, you can select the ideal castor wheel for your purposes.

5. Consider special requirements

Certain conditions necessitate the selection of caster wheels with specific characteristics. Prior to selecting the proper casters, you must identify your specific requirements.

The casters utilized in hospitals, for example, should have safety-enhancing features. The textile industry utilizes caster wheels equipped with thread guards to prevent strings from adhering to them.

Final Thoughts

There are a variety of options for caster wheels on the market, making it difficult to find the best ones for your tasks. You must plan ahead in order to avoid or lessen any difficulties that may arise when purchasing caster wheels.
