... mobile shelving provides a very space efficient means to maximise the storage potential of any particular area.

Empty 6 bay mobile shelving Compactor

1. Definition

offers a quality selection of  Compactor... in new or used  for sale with either handle or wheel drive ... to fit into any space. A fantastic option to increase for filing and storage! A Compactor (or Mobile Shelving unit and often referred to as a Compactus storage system) provides a very space efficient (high storage density) means for filing and storage. Simply put, it is shelving on wheels that runs along tracks.

Instead of many aisles between rows of shelving, this clever design requires only one aisle space to service all of the mobile shelving bays. It is easily one of the best storage solutions sold by Space Rescue.

2. Compactor Dimensions and Sizes

Height: Several different heights, bay widths and shelf depths are available.  Typically the height is between 1800mm and 2400mm with 2200mm being the most common. The number of shelf levels can also be chosen with most of the intermediate shelves being adjustable. Shelf adjustment is achieved through placement of shelf clips on a slotted side panel.

Width: The width of the shelf determines the depth of the unit (from the front to the rear) with 900mm and 1200mm being the most common plus 750mm and 1000mm are also available. Greater unit depths are achieved with tandem or multiple bay depth configurations.  This is achieved by connecting bays through a common side panel to achieve a unit depth of 1800mm (900mm plus 900mm) for example.  

Length: The length is determined by a combination of single sided and double-sided stacks plus an aisle space. In principle, the sum of these lengths is equal to the track length. The depth of the shelves, typically between 300mm and 600mm, determine the width of each stack whilst an aisle of at least 600mm to 700mm is most common.

3. Drive Type ... Handle or Wheel?

The limitation with multiple bay configurations is the movement of the resulting weight of the multiple bay stacks. Whilst a handle is the most common means for moving smaller units, some form of mechanical advantage is often required with the deeper units. This takes the form of either a drive wheel connected by chain or belt via a pulley to the drive wheels. A more expensive alternative to the manual drive systems is an electric motor with key pad controls.

Advantage ... If you would like to convert your Compactor from 'handle' drive to 'wheel' drive, this can easily be achieved. We simply need to change the front track that the unit runs on and add the wheel drive consoles. Alternatively, we can supply this front 'wheel drive' track with your 'handle drive' unit to make it less expensive to convert at a later date if you choose to do so.

4. Compactor Configuration

The most common configuration is to have two single bays at either end with one being static and the other mobile. A combination of mobile double-sided and mobile single-sided bays are placed in between. Depending on the floor layout, you may choose to have the end single-sided static bay on the left or the right hand side. It is important to note that the end that has mobile single-sided bay will have exposed floor tracks when the unit is closed up. Generally it is wise to have the mobile end away from a high foot traffic area so the tracks do not pose a track hazard.

5. Explanation of Other Terms


Explanation: The word Compactus is actually a brand name and is often used to describe shelving systems that are mobile. The most common generic terms are Compactor and Mobile Shelving.

... and ...

Mobile Shelving

Explanation: The term Mobile Shelving is also commonly used to describe this style of shelving. On the other hand, Static Shelving is used to describe shelving that is designed or intended to be stationary.

Interestingly, the term Compactor is used to describe an RUT Shelving system that has a combination of both mobile and static shelving bays.

Another style of shelving system exists for very narrow spaces where security is not such an issue. The bays of shelving actually face you. It consists of a line of shelving bays that are mobile that sit in front of a line of shelves that are stationery. Accessing the rear static shelving is made possible by moving the front mobile bays to the side to create a clear space that provides direct access to the static bay behind. This shelving system is called a Lateral Compactus with the front line of shelving bays moving side to side.

As an alternative to the RUT Steel Shelving internals, a mobile system may also be made out of Longspan Shelving. Similarly, frames are simply placed on runners which in turn run on tracks. Frames are held together by beams.

6. Thoughts

Why are Compactors still the ultimate in space saving?
When you have a bookcase, you need one aisle space in front of it to enable you to gain access to it. With a Compactor, you can access multiple bookcases with just one aisle meaning you can fit more bookcases in the one area. There is no limit to the number of bookcases if you have a large area as long as you leave space for just one aisle. The trick behind this is to put these bookcases on wheels so that you can move the aisle to the bookcase you need access to.

Why are Compactors so versatile?
Compactors are modular and so they can be replicated in both length and depth to fill up an area. There are a number of standard heights, lengths and widths for each module (or bay) to enable you to maximise the space that you have available. When designed and configured correctly, they can be used to suit a variety of applications.
