Stationary racks and equipment can take up a lot of space and be difficult to relocate when needed. Adding casters to your equipment allows you to move it wherever you need to and store it out of the way when you are done.
Choose the Right Casters
If you are going to be pushing your equipment over uneven surfaces, such as concrete with cracks or gravel, you may want to consider spring loaded casters. Additionally, if there are obstacles to movement, such as wood chips, larger diameter wheels may be a good choice. Heavy shop equipment may need wheels that are at least 2 to 2.5 inches in diameter. Wheels made from rubber or plastic are best for hard surfaces or carpet. Metal wheels are designed to withstand rough surfaces.
Determine the Weight Capacity
Overloading your casters can cause them to break or collapse. You will need to calculate the load you plan to be moving around before picking a caster. You do not have to come up with an exact calculation but err on the side of too much weight capacity. Be sure to include the weight of the equipment you plan to move and the weight of anything that will be placed on the equipment. When you have your weight estimate, divide that by the number of casters you will be using. This will give you the weight capacity you need for each caster. However, if you are carrying an uneven load, you will want to increase the capacity of the casters to account for that.
Choose the Right Mount
Casters usually mount with either stems or plates. Plate mounts are best for solid, flat surfaces.
Adding casters to your equipment can greatly increase the flexibility and convenience of the equipment. Be sure to choose the right casters for the job you plan to do.
