Medical Cart Caster Options (Infographic)

The choice of caster used on your medical cart has a huge impact on maneuverability, staff comfort, safety, and compliance for your medical device system. Scroll through a website or leaf through a catalog from any caster manufacturer, and you’ll see lots of options. Where do you start?

We’ve broken down some common caster options and terms for you to get you started. From there, you can make some informed decisions about the right caster for your project. You can download our “Quick Guide to Medical Cart Caster Options” Infographic or read on for more info!

Let’s start with some questions that will help you get you “rolling”.
Where will the medical device be used?

Certain environments will require specialized features on the casters of your cart.

For example, carts meant to carry sensitive electronic medical devices safely in lab areas may require ESD management. For this type of cart, we would source conductive casters to prevent equipment malfunctions and static shocks.

Another environment that requires specialized casters is the MRI room. Any magnetic material can interfere with the safe use of the MRI machine, and suppliers offer all-plastic non-magnetic casters for this use.

Finally, sanitization of carts and devices means that casters will be exposed to water. Casters built for washability are made with all stainless steel metal parts to avoid rust and corrosion.

How does the cart need to be moved?
Balance maneuverability and stability to get your cart where it needs to go.

The two main movement types of casters are rigid casters and swivel casters. Rigid casters (also called fixed casters) allow the medical device to be moved back and forth on a straight path. This makes the cart very stable, since it will not swerve, but naturally makes it less maneuverable. In some cases rigid casters may be combined with swivel casters on the same frame.

Swivel casters, of course, allow for rotation of the wheel and can change direction during movement. This offers greater mobility during transport and finite adjustments in the area where the medical device will be used. But we’ve all had the experience of trying to maneuver a loaded grocery cart to the checkout…

Finally, for ultimate stability and safety in large loads, there is the twin-wheel caster. The dual-mounted wheels reduce tipping hazards, displace the weight of the cart if it rolls over a cord (or a toe!), and are not likely to get stuck in gaps like elevator doorways.

What locking options are needed?
It’s likely you need the casters to lock for IEC 60601-1 3rd ed. compliance… but consider usability as well!

In our infographic, we’ve highlighted four common locking mechanism options common for casters used in medical device carts.

A directional lock disables the “swivel” movement from a wheel to allow it to move back and forth only.

A total lock is just what it sounds like… it prevents the wheel from both rolling and swiveling.

A dual lock gives the operator the option for directional locking or total locking on each individual wheel.

A central wheel lock allows the operator to lock all wheels simultaneously.


4 Features to Look for in Medical equipment caster wheels

A busy medical center is constantly on the move and from every critical patient that is brought in to any imaging that is conducted, casters play their part. They are the backbone of any in-center movement involving equipment such as stretchers, wheelchairs, mobile X-ray machines, and critical care carts among others. However, it can be said that casters don’t get the recognition they deserve. In fact, let me say that a bad caster gets more attention than a good one.

Considering the critical nature of their job in medical equipment, you can’t go with just any casters. You need casters that are made for the job. Therefore, do give casters due consideration, whether you are buying new medical equipment, or are replacing the existing casters on any piece of equipment.

The next logical question can be what you should look for in casters to be used in the healthcare industry. This is where we can help. In this piece, we will go over four of the must-have features in Medical equipment caster wheels. So, without further ado let’s get right into it.

1. Durability
Just like in most things, durability is a feature you can’t ignore in casters. And in medical equipment, this feature becomes even more critical as it makes them dependable. The durability of casters is directly related to their material of construction. In casters, you have wheels, axles, forks, and brakes and generally, wheels are made up of different material than the rest of the caster.

In wheels, you will find materials such as metal, polyurethane, rubber, and plastic among others. As you can guess, these materials have different characteristics and all of them have their fair share of pros and cons. In metal, you will find wheels made up of steel and cast iron. These wheels have great weight capacity and tensile strength along with resistance to heat and general wear and tear. However, they are mostly heavy in weight, are noisy, and don’t provide the best floor protection.

For use in the healthcare industry, it is better to go with caster wheels made up of either rubber or polyurethane. These materials have good wear and abrasion resistance and provide better floor protection and above all have a quieter operation which makes them good for use in hospital settings.

In other parts of the caster like forks, axles, plates, and stems, you will find materials such as steel, cast iron, and plastic. These parts should have the much-needed structural strength that would make them last long and work efficiently. For these parts, it is better to go with steel as it has good strength and durability. However, make sure it has some sort of coating to protect against rust and corrosion. Some of the finishes you can easily find include zinc plating, chrome plating, and nickel plating.

2. Noise Reduction
In the healthcare industry, patient comfort is of utmost importance. In such settings, the clunk and clatter of casters can be a nuisance and can adversely affect patient comfort. Moreover, they can also disturb hospital workers including doctors and nurses, and make them lose their focus. Therefore, you should go with casters that don’t produce much noise during their operation.

For this purpose, we recommend that medical centers should go with softer tread wheels. In addition to lower noise levels, these casters cause minimal damage to the floor. Soft polyurethane treads are easier to move than plaster casters and are quieter than metal casters.

In other aspects, go for materials that grip the floor and reduce caster chatter. This usually occurs when the load capacity is low and as a result, there is back and forth swinging of the rig. For this attribute, go for materials such as urethane and neoprene.

These materials are also good at keeping your floors scratch-free as they are non-marking.

3. Shock Loading Reduction
In simple terms, shock loading means when there is a sudden increase in load. For example, when the load is placed from a height to another surface and there is an uneven distribution of load. Some of the machines used in the healthcare industry are sensitive to such shocks as this can damage them. Therefore, for transfers of such machines, you need casters that can reduce/eliminate the effects of such shocks.

Therefore, look for carts or racks that provide good shock loading reduction. They usually have spring-loaded casters and this helps them reduce the shock experienced by sensitive machinery.

4. Good Braking and Locking Mechanism
Having a good braking and locking mechanism is another of the must-have features for medical casters. This will help keep any equipment in place when some sort of procedure is going on. Be it IV poles, anesthesia carts, or even hospital linen carts, you only need them to move when you want them to. Otherwise, any uncontrolled/unwanted movement can have serious consequences.

In casters, you are mostly going to find ideal-stop brake, total lock brake, or tech lock brake mechanisms. All of them have different working mechanisms and are effective at controlling caster movement. However, for medical equipment, we recommend casters with total lock brakes. These brakes lock both the caster swivel and wheel rotation. So, essentially, you are taking care of both the swivel and rotation of the casters and you don’t have to worry about having several locking mechanisms.
