Often when you need to add casters to make carts or equipment move easier, you also need to have a way of making sure that your equipment only moves when you want and not at an inconvenient time. Be it holding a large piece of equipment in place until you need to move it for routine maintenance or cleaning, or loading a cart onto a truck that needs to stay in place on the truck until it is time to unload; braking casters are the ideal solution to keep something in place until you need to move it easily.
At Douglas Equipment we have almost 60 years of experience in helping people like you choose the right caster for their special project or unique job. Our team of trained professionals can help you decide what type of caster you need, when to add a brake and what type of brake is right for your job.
Friction Brakes & Tread Lock Brakes
Probably the first reason you can think of for a caster brake is to stop the wheel from rotating. This will of course keep the cart or equipment from rolling away when you want it to stay put. There are two main types of brakes for this application: friction brakes and tread lock brakes. The friction brake is very popular and can be recognized as a side mounted peddle that will lock the wheel in position when engaged by putting friction on the side body of the wheel. The tread lock brake sits over the wheel of the caster and when engaged presses against the wheel tread to hold it in place.

Wheel materials include soft rubber, hard rubber, polyurethane, polyolefin, Monotech and Vipor for almost any flooring type you need to match. Either the friction or tread lock brake is available on these casters.
Directional Lock Swivel Caster Brakes
With a swivel caster you have the mobility to maneuver the cart or equipment more easily since the casters themselves are allowed to turn. This can make it very easy to place a cart into a tight place, but what if you only need this maneuverability some of the time and need to have the wheels stay straight to move more quickly down a straight hallway? Here is where a caster with a directional lock comes in handy; you can lock the swivel part of the caster wheel in the straight position to move quickly down a straight hall with the lock in place, but then unlock the swivel and allow the caster to have full maneuverability when you need to move into a tight spot.

Types of Self-Braking Casters: Compression vs. Decompression Brakes
Self-braking casters are often useful for chair casters, and there are two self-braking options that work well. A decompression brake holds the caster in place when weight is removed and a compression brake holds the caster in place when weight is applied. The first braking option would allow for chair movement when a person was seated but would stop the chair form rolling away when the person rose from the chair, while the second option would stop the chair from moving when the person was seated.
