19-inch Rack
A 19-inch rack is a standardized frame or enclosure for mounting multiple electronic equipment modules. Each module has a front panel that is wide. The 19 inch dimension includes the edges or "ears" that protrude from each side of the equipment, allowing the module to be fastened to the rack frame with screws or bolts. Common uses include computer servers, telecommunications equipment and networking hardware, audiovisual production gear, and scientific equipment. Overview and history Equipment designed to be placed in a rack is typically described as rack-mount, rack-mount instrument, a rack-mounted system, a rack-mount chassis, subrack, rack cabinet, rack-mountable, or occasionally simply shelf. The height of the electronic modules is also standardized as multiples of or one rack unit or U (less commonly RU). The industry-standard rack cabinet is 42U tall; however, 45U racks are also common.

Bicycle Stand
A bicycle parking rack, usually shortened to bike rack and also called a bicycle stand, is a device to which bicycles can be securely attached for parking purposes. A bike rack may be free standing or it may be securely attached to the ground or some stationary object such as a building. Indoor bike racks are commonly used for private bicycle parking, while outdoor bike racks are often used in commercial areas. General styles of racks include the Inverted U, Serpentine, Bollard, Grid, and Decorative. The most effective and secure bike racks are those that can secure both wheels and the frame of the bicycle, using a bicycle lock. Bike racks can be constructed from a number of different materials. Durability, weather resistance, appearance, and functionality are extremely important factors when choosing the material of the bike rack. Construction materials include stainless steel, steel, recycled plastic, or thermoplastic. Each material has advantages and disadvantages, and each ...

Pallet Racking
Pallet rack is a material handling storage aid system designed to store materials on pallets (or “skids”). 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. Selective pallet racking systems Selective pallet racking is a common pallet racking system in use today. Selective pallet racking systems typically come in one of two configurations: a roll formed, or clip-in configuration, and a structural bolt-together configuration. #Roll formed selecti ...

Roof Rack
A roof rack is a set of bars secured to the roof of a motor car. It is used to carry bulky items such as luggage, bicycles, canoes, kayaks, skis, or various carriers and containers. They allow users of an automobile to transport objects on the roof of the vehicle without reducing interior space for occupants, or the cargo area volume limits such as in the typical car's trunk design. These include car top weatherproof containers, some designed for specific cargo such as skis or luggage. History There is a long history of the use of roof racks and their designs. Until the late 1970s, almost all regular passenger automobiles had rain gutters. These gutters are formed by the welded flange (raised rim or lip) on the left and right sides of the car's metal roof panel. This made attaching an accessory or aftermarket roof rack a relatively simple process. The first mass production cars without any visible rain gutters were the 1975 AMC Pacer and Chevrolet Monza. Other vehicles ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Laboratory Drying Rack
Laboratory drying rack is a pegboard for hanging and draining glassware in a laboratory. It is available in different varieties and sizes. It can be used for different materials of glassware in the laboratory room such as funnels, pipettes, mixing balls, slides, bottle stoppers, tubing and so on.Lab Drying Racks. (2016). ''M2 Scientifics.'' Retrieved from: https://www.m2scientifics.com/100-lab-drying-racks In addition to that, the pegs on the drying rack are easily removable and replaceable in order to maintain the cleaning of the lab racks to avoid contamination with other apparatus used on the same rack. Any common laboratory needs to have at least two or three drying racks per lab.Mallapaty G.(2001). Equipment Requirements for a PHC Centre Laboratory. ''The Public Health Care Laboratory.''

Rack (billiards)
A rack (sometimes called a triangle) is a piece of equipment that is used to place billiard balls in their starting positions at the beginning of a pocket billiards game. ''Rack'' may also be used as a verb to describe the act of setting billiard balls in their starting positions (e.g. "to rack the balls"), or as a noun to describe a set of balls that are in their starting positions (e.g. "a rack of balls", more often called a ''pack'' or a ''pyramid'' in British English). Traditional racks are in the form of triangular frames, usually made from wood, plastic or metal. A modern variation, called a ''template rack'', is made from a thin material (usually 0.14 mm or less) that contains precision cut-outs to hold the balls in place. Purported benefits of template racks include a more consistent racking, and their popularity has warranted specific inclusion in profession rules. Unlike traditional racks, template racks are left on the table during the break shot and removed at the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rack And Pinion
A rack and pinion is a type of linear actuator that comprises a circular gear (the '' pinion'') engaging a linear gear (the ''rack''). Together, they convert rotational motion into linear motion. Rotating the pinion causes the rack to be driven in a line. Conversely, moving the rack linearly will cause the pinion to rotate. A rack and pinion drive can use both straight and helical gears. Though some suggest helical gears are quieter in operation, no hard evidence supports this theory. Helical racks, while being more affordable, have proven to increase side torque on the datums, increasing operating temperature leading to premature wear. Straight racks require a lower driving force and offer increased torque and speed per percentage of gear ratio which allows lower operating temperature and lessens viscal friction and energy use. The maximum force that can be transmitted in a rack and pinion mechanism is determined by the tooth pitch and the size of the pinion as well as the gear ...

Rack Unit
A rack unit (abbreviated U or RU) is a unit of measure defined as . It is most frequently used as a measurement of the overall height of 19-inch and 23-inch rack frames, as well as the height of equipment that mounts in these frames, whereby the height of the frame or equipment is expressed as multiples of rack units. For example, a typical full-size rack cage is 42U high, while equipment is typically 1U, 2U, 3U, or 4U high. Definition The rack unit size is based on a standard rack specification as defined in EIA-310. The Eurocard specifies a standard rack unit as the unit of height; it also defines a similar unit, horizontal pitch (HP), used to measure the width of rack-mounted equipment. The standard was adopted worldwide as ''IEC 60297 Mechanical structures for electronic equipment – Dimensions of mechanical structures of the series'', and defines the sizes for rack, subrack (a shelf-like chassis in which cards can be inserted), and the pitch of printed circuit boards/ca ...

Bustle Rack
A bustle rack is a type of storage bin mounted on combat vehicles, usually on the sides and/or rear of the turret. These racks are used to carry extra gear and supplies for the vehicle in the field, as well as give the crew a place to store their belongings so that they don't take up the already cramped space inside the vehicle. On the U.S. Abrams tank The original rack design for the XM1 and first production M1 Abrams tanks was blueprinted by then 1LT John A. Baker III, XO and Company Maintenance Officer, H Co, 2-6 CAV, Ft. Knox, KY. Baker had previously developed the standard combat load plan for M60A1 tanks for the Rapid Deployment Force (RDF), 194th Armored Brigade in the early 1980s. Upon joining the Army's first XM1/M1 unit, H Co, 2-6 CAV, Baker and his platoon tested every aspect of the XM1 seven days a week for months on end, putting the Army's newest battle tank through its paces. Baker and his men became painfully aware that the vehicle's stowage would be significantl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Firearm Rack
A gun rack, also known as a firearm rack, rifle rack, or arm rack, is a rack used for storing firearms such as long guns and handguns. They can be used for regular storage or display. Gun racks are often designed to hold a gun pointing up, with its stock or grip touching the bottom of the rack. Sections on the rack may be intended as slots to secure the gun and keep it secure in place, often placed at the barrel, barrel shroud, or stock. Gun racks typically have locks to prevent theft or improper use. Gun racks can be mounted onto vehicles to carry firearms; indeed, the shooting brake originated as a hunting vehicle designed to carry guns in this fashion. Aftermarket gun racks can be mounted onto vehicles such as all-terrain vehicles, side-by-sides, military vehicles, SWAT vehicles, and other types. See also *Gun safe A gun safe is a safe designed for storing one or more firearms and/or ammunitions. Gun safes are primarily used to prevent access by unauthorized or unqu ...
