Small mobile aisle shelving / roller racking system
Mobile shelving, mobile aisle shelving, compactus,roller racking, or rolling stack, are terms applied to shelving or storage units fitted with wheeled traction systems. Units can be closely packed when access is not required, but can be readily moved to open up an aisle to allow access. By eliminating the need for a permanently open aisle between every unit, a smaller proportion of floor space can be allocated to storage than in the case of conventional fixed shelving, or a higher capacity of storage can be met using the same footprint as fixed shelving.
Each shelving unit is normally mounted on a level trackway (to eliminate gradients in the supporting floor), making it possible to move heavy units with minimal effort. Mobile shelving can be moved manually or by the use of electrical motors. The track/flooring can either sit on top of an existing floor or be integrated into raised access flooring allowing for a smooth transition between unit and surrounding floor levels.

Mobile storage systems are usually constructed with a rotary handle on the exterior accessible face. When rotated, the handle operates the mechanism which winds the single, connected, filing unit either left or right, depending on a clockwise or counter-clockwise rotation of the handle. In an office, for example, several stacks of movable filing cabinets may be accommodated in a limited space.
Drive mechanisms vary; traditionally systems were offered with chain drive but modern technology allows belt drive systems which provides smooth, quiet operation.
Although the "bays of shelving" that sit on the mobile chassis come in many standard sizes, they can be mixed to create run lengths of shelving to maximise the room length.
The tracks can be installed onto many different types of floor and on different levels. The tracks themselves can either have a false floor running in between so that the tracks do not become trip hazards, or they can be put into the floor (usually concrete floor) or have small ramps on either side of the tracks. Either option creates a hazard-free floor and track system.
Powered mobile shelving
Powered mobile shelving
Powered shelving is electrically powered. Units normally have a small AC or DC motor hidden in the base that automatically moves the units when a single button is pressed. High-end versions connect into archiving databases, and using RFID allows the easy retrieval of archived items with auto-open and close functions.
Applications
Princeton University's Firestone Library's mobile aisle shelving / roller racking system
Mobile aisle shelving is typically used for academic or commercial applications where a significant volume of physical archive material, filing or books is to be stored. These include medical or government records, file-intensive offices such as the legal or accountancy professions, and public and academic libraries and similar archives.
Another common use is in retail stockrooms to maximise the stock capacity, or to reduce the back of house storage space required so that a greater proportion of the overall shop space can be used for customer retail purposes.
Capacity, siting and speed advantages
A typical bank of mobile office shelving units offers close to a 50% reduction of floor space, or a 50% to 100% increase in storage space, compared to traditional filing cabinets. The ability to concertina individual units until touching means space is only required between units when they are being accessed by users. Applications with a greater number of simultaneous users may require more access spaces (aisles), thus not approaching this 50% target so closely.
When the bank of units is closed, the contents are protected from light and dust, and the whole bank of units can be secured by locking the end unit(s) in place. This makes mobile shelving ideal for holding museum and archive collections.
In computing, a computer file is a resource for recording data on a computer storage device, primarily identified by its filename. Just as words can be written on paper, so can data be written to a computer file. Files can be shared with and transferred between computers and mobile devices via removable media, networks, or the Internet.
A hard disk drive (HDD), hard disk, hard drive, or fixed disk, is an electro-mechanical data storage device that stores and retrieves digital data using magnetic storage with one or more rigid rapidly rotating platters coated with magnetic material. The platters are paired with magnetic heads, usually arranged on a moving actuator arm, which read and write data to the platter surfaces. Data is accessed in a random-access manner, meaning that individual blocks of data can be stored and retrieved in any order. HDDs are a type of non-volatile storage, retaining stored data when powered off. Modern HDDs are typically in the form of a small rectangular box.
A forklift is a powered industrial truck used to lift and move materials over short distances. The forklift was developed in the early 20th century by various companies, including Clark, which made transmissions, and Yale & Towne Manufacturing, which made hoists. Since World War II, the use and development of the forklift truck have greatly expanded worldwide. Forklifts have become an indispensable piece of equipment in manufacturing and warehousing. In 2013, the top 20 manufacturers worldwide posted sales of $30.4 billion, with 944,405 machines sold.
An aisle is a linear space for walking with rows of non-walking spaces on both sides. Aisles with seating on both sides can be seen in airplanes, in buildings such as churches, cathedrals, synagogues, meeting halls, parliaments, courtrooms, theatres, and in long passenger vehicles. An aisle floor may be level or, as in theatres, sloping upward from a stage.
Logistics automation is the application of computer software or automated machinery to improve the efficiency of logistics operations. Typically this refers to operations within a warehouse or distribution center, with broader tasks undertaken by supply chain engineering systems and enterprise resource planning systems.
A baler or hay baler is a piece of farm machinery used to compress a cut and raked crop into compact bales that are easy to handle, transport, and store. Often, bales are configured to dry and preserve some intrinsic value of the plants bundled. Different types of balers are commonly used, each producing a different type of bale – rectangular or cylindrical, of various sizes, bound with twine, strapping, netting, or wire.
IBM manufactured magnetic disk storage devices from 1956 to 2003, when it sold its hard disk drive business to Hitachi. Both the hard disk drive (HDD) and floppy disk drive (FDD) were invented by IBM and as such IBM's employees were responsible for many of the innovations in these products and their technologies. The basic mechanical arrangement of hard disk drives has not changed since the IBM 1301. Disk drive performance and characteristics are measured by the same standards now as they were in the 1950s. Few products in history have enjoyed such spectacular declines in cost and physical size along with equally dramatic improvements in capacity and performance.
In computing, a file system or filesystem is a method and data structure that the operating system uses to control how data is stored and retrieved. Without a file system, data placed in a storage medium would be one large body of data with no way to tell where one piece of data stopped and the next began, or where any piece of data was located when it was time to retrieve it. By separating the data into pieces and giving each piece a name, the data are easily isolated and identified. Taking its name from the way a paper-based data management system is named, each group of data is called a "file". The structure and logic rules used to manage the groups of data and their names is called a "file system."
A bookcase, or bookshelf, is a piece of furniture with horizontal shelves, often in a cabinet, used to store books or other printed materials. Bookcases are used in private homes, public and university libraries, offices, schools, and bookstores. Bookcases range from small, low models the height of a table to high models reaching up to ceiling height. Shelves may be fixed or adjustable to different positions in the case. In rooms entirely devoted to the storage of books, such as libraries, they may be permanently fixed to the walls and/or floor.
In computing, a system resource, or simple resource, is any physical or virtual component of limited availability within a computer system. All connected devices and internal system components are resources. Virtual system resources include files, network connections, and memory areas.
An automated guided vehicle (AGV), different from an autonomous mobile robot (AMR), is a portable robot that follows along marked long lines or wires on the floor, or uses radio waves, vision cameras, magnets, or lasers for navigation. They are most often used in industrial applications to transport heavy materials around a large industrial building, such as a factory or warehouse. Application of the automatic guided vehicle broadened during the late 20th century.
An automated storage and retrieval system consists of a variety of computer-controlled systems for automatically placing and retrieving loads from defined storage locations. Automated storage and retrieval systems (AS/RS) are typically used in applications where:
An NTFS reparse point is a type of NTFS file system object. It is available with the NTFS v3.0 found in Windows 2000 or later versions. Reparse points provide a way to extend the NTFS filesystem. A reparse point contains a reparse tag and data that are interpreted by a filesystem filter driver identified by the tag. Microsoft includes several default tags including NTFS symbolic links, directory junction points, volume mount points and Unix domain sockets. Also, reparse points are used as placeholders for files moved by Windows 2000's Remote Storage Hierarchical Storage System. They also can act as hard links, but are not limited to pointing to files on the same volume: they can point to directories on any local volume. The feature is inherited to ReFS.
Pallet rack is a material handling storage aid system designed to store materials on pallets. Although there are many varieties of pallet racking, all types allow for the storage of palletized materials in horizontal rows with multiple levels. Forklift trucks are usually required to place the loaded pallets onto the racks for storage. Since the Second World War, pallet racks have become a ubiquitous element of most modern warehouses, manufacturing facilities, retail centers, and other storage and distribution facilities. All types of pallet racking increase storage density of the stored goods. Costs associated with the racking increases with increasing storage density.
Material handling equipment (MHE) is mechanical equipment used for the movement, storage, control, and protection of materials, goods and products throughout the process of manufacturing, distribution, consumption, and disposal. The different types of equipment can be classified into four major categories: transport equipment, positioning equipment, unit load formation equipment, and storage equipment.
A server room is a room, usually air-conditioned, devoted to the continuous operation of computer servers. An entire building or station devoted to this purpose is a data center.
Evidence management is the administration and control of evidence related to an event so that it can be used to prove the circumstances of the event, and so that this proof can be tested by independent parties with confidence that the evidence provided is the evidence collected related to the event.
A journaling file system is a file system that keeps track of changes not yet committed to the file system's main part by recording the goal of such changes in a data structure known as a "journal", which is usually a circular log. In the event of a system crash or power failure, such file systems can be brought back online more quickly with a lower likelihood of becoming corrupted.
In library science and architecture, a stack or bookstack is a book storage area, as opposed to a reading area. More specifically, this term refers to a narrow-aisled, multilevel system of iron or steel shelving that evolved in the 19th century to meet increasing demands for storage space. An "open-stack" library allows its patrons to enter the stacks to browse for themselves; "closed stacks" means library staff retrieve books for patrons on request.
The cultural property storage typically falls to the responsibility of cultural heritage institutions, or individuals. The proper storage of these objects can help to ensure a longer lifespan for the object with minimal damage or degradation. With so many different types of artifacts, materials, and combinations of materials, keepers of these artifacts often have considerable knowledge of the best practices in storing these objects to preserve their original state.
