Historical Background
The concept of distributing weight across multiple points of support has been a fundamental principle in engineering and construction for centuries. The invention of casters (wheels designed to be mounted to the underside of a vehicle or piece of equipment) has revolutionized the way we move and manage heavy loads, allowing for the easy transportation of furniture, machinery, and other heavy objects.
Calculation Formula
The caster weight (CW) can be calculated using the formula:
\[ CW = \frac{W}{C} \]
where:
 \(CW\) is the Caster Weight in pounds (lbs),
 \(W\) is the total weight in pounds (lbs),
 \(C\) is the number of casters.
Example Calculation
Suppose you have a piece of equipment that weighs 200 pounds, and you plan to mount it on 4 casters. Using the formula:
\[ CW = \frac{200}{4} = 50 \text{ lbs per caster} \]
Each caster must be able to support at least 50 pounds.
Importance and Usage Scenarios
Calculating the caster weight is crucial for ensuring the stability and safety of mobile platforms. It helps in selecting the appropriate casters that can support the weight without failure, preventing accidents and equipment damage.
Common FAQs

What factors should I consider besides weight when selecting casters?
 Besides the weight capacity, consider the floor surface, caster material, and the presence of any environmental factors like chemicals or extreme temperatures.

How does the distribution of weight affect caster selection?
 Uneven distribution can lead to some casters bearing more load than others. It's important to estimate weight distribution accurately or choose casters with a higher weight capacity to account for potential imbalances.

Can I use casters of different sizes on the same equipment?
 It's generally recommended to use casters of the same size to ensure even distribution of weight and to maintain the equipment level.
This calculator offers a straightforward way to calculate the required weight capacity per caster, aiding in the safe and efficient design of mobile platforms and equipment.
