Central-locking Caster Brakes

Central-locking Caster Brakes

When it comes to brakes, you have a ton of options that will match your exact needs. One option you have is a central-locking brake, which allows you to secure all wheels with one brake pedal.

Recently, we’ve allowed our clients to easily design and order their own central-locking brake system. We construct all of the pieces you will need after you’ve supplied us with one or two measurements. In this way, you can get exactly what you need quickly and effortlessly.


The central-locking brake system is fairly straightforward. When our clients have multiple swivel casters and need to securely stop these swivel casters with a total lock brake, they have the option to use 2 to 4 individual brake pedals or to use one lever that controls all of these brakes at once.


Central Locking Brake for Casters


Because you control multiple brakes with one pedal, you gain several advantages.


First, the pedal is always in one place. This means that you don’t have to maneuver your carts to try and find the brake pedal, which may swivel around with your caster. All brakes are always accessible and easily engaged with one pedal.


Second, you have total lock brakes on all casters, so you have a much more stable cart. Whether you’re a tier 1 auto manufacturer that needs an immobile cart during transport or a Broadway play set that needs highly mobile carts in between scenes but immobile carts during each scene, central-locking systems provide you with this versatility.


All of these advantages provide you with major savings in time, productivity, and therefore revenue. Not to mention, these brakes makes life easier and much less tedious in that you have to press one lever rather than 4.



In order to create your own custom brake, simply provide us with the measurement of your cart from center of your left and right wheel as you can see below.


Central Stop Mock Up


When you have supplied us with your measurement, we will send you the casters and central-locking pedal with your exact measurements. The installation is straightforward, and we are always available for any assistance you might need.

Central locking caster system as a caster system solution

System solutions.

Coherently designed products for your individual requirements.

Alongside the “simple” castor, we offer more and more caster system solutions. The underlying idea is to offer our customers genuine added value in the form of additional functions and in combination with STEINCO castors. One new product from this range is the so-called central locking caster system (zFS) with which you can lock multiple castors at the same time.

Central locking caster system (zFS)

The ZFs caster system is freely configurable: depending on the construction, this allows either secure locking of all four of a unit’s castors, or cost-effective partial locking for a unit that can function safely with just two locked castors.

In both cases, the caster locking system mechanically ensures that the castors are simultaneously locked or free to move. This prevents known incorrect usage and provides the highest possible efficiency. Regardless of whether full or partial locking is selected, single or double-sided controls can be implemented. This makes it possible to take specific ergonomic requirements into account.

The colour coding of the control pedal is self-explanatory and its position gives a clear and direct indication of system status.

Individual Locking: Casters

While the central locking system makes it possible to lock all casters on faster, which is of great advantage in some areas, the individual caster lock offers

With caster locking mechanisms, a distinction is made between individual locking and central locking.

The former is standard: Each caster has a locking mechanism which can be used to lock and unlock it. The central locking also allows all the castors on the device to be locked at one time by activating the lock on one caster.

While the central locking system makes it possible to lock all casters on faster, which is of great advantage in some areas, the individual caster lock offers the ability to flexibly stop individual casters.

Types of caster locking

The locking mechanisms include the load-dependent brake, the wheel and directional brake, and the total lock. The load-dependent brake is used, for example, for chair casters. In this case, the casters are not locked when loaded, but are locked when unloaded. As their names suggest, the wheel brale and directional lock lock different parts of the caster. The wheel brake locks the wheel, so it can no longer turn.

However, it is still possible to swivel the wheel in the bearing. Exactly the opposite is the case with the directional lock. Here, it is not possible to swivel the wheel in the locked state, but the wheel can still turn. This makes it possible to transform a swivel caster into a rigid caster temporarily, in order to make it easier to travel in a straight line. A combination of these two types is the total lock: This locks both the wheel and the swivel at the same time, so that that the caster can neither run nor swivel.
