Box Crib
A box crib or cribbing is a temporary wooden structure used to support heavy objects during construction, Structural move, relocation, vehicle extrication and urban search and rescue. It is commonly used to secure overturned motor vehicles, and debris within collapsed buildings. Cribbing is often used in conjunction with other stabilization equipment, such as pneumatic or hydraulic shoring. Cribbing is also used in sub-surface mining as a roof support. Cribbing has largely been replaced by hydraulic jack, hydraulic shoring in modern mining applications. Some forms of cribbing can be used on movie sets and/or production sites for stabilizing dolly tracks, platforms, and various temporary structures when quick setup times are needed. Stability The stability of a crib is affected by a variety of factors: the material used (often a soft wood which gives audible warnings before failure), the number of contact points between the crib and the supported surface, the ratio of the footp ...

Jack (device)
A jack is a mechanical lifting device used to apply great forces or lift heavy loads. A mechanical jack employs a screw thread for lifting heavy equipment. A hydraulic jack uses hydraulic power. The most common form is a car jack, floor jack or garage jack, which lifts vehicles so that maintenance can be performed. Jacks are usually rated for a maximum lifting capacity (for example, 1.5 tons or 3 tons). Industrial jacks can be rated for many tons of load. Etymology The personal name ''Jack'', which came into English usage around the thirteenth century as a nickname form of ''John'', came in the sixteenth century to be used as a colloquial word for 'a man (of low status)' (much as in the modern usage 'jack of all trades, master of none'). From here, the word was 'applied to things which in some way take the place of a lad or man, or save human labour'. The first attestation in the ''Oxford English Dictionary'' of ''jack'' in the sense 'a machine, usually portable, for lifti ...

Rescue
Rescue comprises responsive operations that usually involve the saving of life, removal from danger, liberation from restraint, or the urgent treatment of injury, injuries after an incident. It may be facilitated by a range of tools and equipment necessary to deal with the specific circumstances. Rescues may be necessary in a wide range of circumstances and environments, and specialised procedures have been developed for many of these. A rescue may also be performed on an ad hoc basis by the people who are available on site, using equipment available on site or assembled from available materials, particularly when the rescue is urgent or it is unlikely that specialist assistance will be available within a reasonable time. First aid medical attention is often closely associated with rescue, and may be a necessary part of a rescue. Equipment used might include search and rescue dogs, mounted search and rescue horses, helicopters, the "Hydraulic rescue tools, jaws of life", and o ...

Shoring
Shoring is the process of temporarily supporting a building, vessel, structure, or trench with shores (Jack post, props) when in danger of collapse or during repairs or alterations. ''Shoring'' comes from ''shore'', a timber or metal prop. Shoring may be vertical, angled, or horizontal. Methods Buildings Raking shores In this method, inclined members called rakers are used to give temporary lateral support to an unsafe wall. One or more timbers slope between the face of the structure to be supported and the ground. The most effective support is given if the raker meets the wall at an angle of 60 to 70 degrees. A wall-plate is typically used to increase the area of support. Foundations Shoring is commonly used when installing the Foundation (engineering), foundation of a building. A shoring system such as piles and lagging or shotcrete will support the surrounding loads until the underground levels of the building are constructed. Commonly used shoring equipment includes post s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Crib Barn
Crib barns were a popular type of barn found throughout the U.S. south and southeast regions. Crib barns were especially ubiquitous in the Appalachian and Ozark Mountain states of North Carolina, Virginia, Kentucky, Tennessee, Missouri, East Oklahoma and Arkansas. Design These barns were composed of multiple cribs, up to six, which were used for feed storage or livestock pens. Crib barn construction was somewhat simplistic compared to other types of barns, such as the prairie barn or the round barn, which gained popularity in American agriculture. Crib barns were most often built of unchinked logs and may or may not have included a hay loft depending on the specific barn. Unaltered examples of crib barns usually have roofs covered with undressed wood shingles, which, over time, were replaced with tin or asphalt. It is the rustic appearance of crib barns that cause them to stand out.Auer, Michael JThe Preservation of Historic Barns Preservation Briefs, National Park Service, f ...

Rigger (industry)
A rigger or slinger is a skilled tradesperson who specializes in the assistance of manual mechanical advantage device comprising pulley, block and tackle or motorised such as a crane or derrick or chain hoists (chain fall) or capstan winch. Etymology The term comes from the days of sailing ships, when a rigger was a person who worked with rigging, that is, ropes for hoisting the sails. Sailors could put their rope skills to work in lifting and hauling. In an era before mechanical haulage and cranes, ropes, pulleys and muscle power were all that was available to move heavy objects. A specialized subset are telecommunication riggers, entertainment industry riggers. In time, rigging became a trade in itself, giving rise to modern usages with some original terminology remaining, with its roots all but forgotten. Description Riggers attach loads of equipment to cranes or structures using shackles, cables, chains, clamps or straps, employing pulleys, winches, lifts or chain hoists ...

Heavy Industry
Heavy industry is an industry that involves one or more characteristics such as large and heavy products; large and heavy equipment and facilities (such as heavy equipment, large machine tools, huge buildings and large-scale infrastructure); or complex or numerous processes. Because of those factors, heavy industry involves higher capital intensity than light industry does, and is also often more heavily cyclical in investment and employment. Though important to economic development and industrialization of economies, heavy industry can also have significant negative side effects: both local communities and workers frequently encounter health risks, heavy industries tend to produce byproducts that both pollute the air and water, and the industrial supply chain is often involved in other environmental justice issues from mining and transportation. Because of their intensity, heavy industries are also significant contributors to greenhouse gas emissions that cause climate ...

Farm Equipment
Agricultural machinery relates to the mechanical structures and devices used in farming or other agriculture. There are many types of such equipment, from hand tools and power tools to tractors and the farm implements that they tow or operate. Machinery is used in both organic and nonorganic farming. Especially since the advent of mechanised agriculture, agricultural machinery is an indispensable part of how the world is fed. Agricultural machinery can be regarded as part of wider agricultural automation technologies, which includes the more advanced digital equipment and agricultural robotics. While robots have the potential to automate the three key steps involved in any agricultural operation (diagnosis, decision-making and performing), conventional motorized machinery is used principally to automate only the performing step where diagnosis and decision-making are conducted by humans based on observations and experience.

Heavy Equipment
Heavy equipment, heavy machinery, earthmovers, construction vehicles, or construction equipment, refers to heavy-duty vehicles specially designed to execute construction tasks, most frequently involving earthwork operations or other large construction tasks. ''Heavy equipment'' usually comprises five equipment systems: the implement, traction, structure, power train, and control/information. Heavy equipment has been used since at least the 1st century BC, when the ancient Roman engineer Vitruvius described a crane powered by human or animal labor in ''De architectura''. Heavy equipment functions through the mechanical advantage of a simple machine that multiplies the ratio between input force applied and force exerted, easing and speeding tasks which often could otherwise take hundreds of people and many weeks' labor. Some such equipment uses hydraulic drives as a primary source of motion. The word plant, in this context, has come to mean any type of industrial equip ...

Hydraulic Rescue Tools
Hydraulic rescue tools, also known as jaws of life, are used by Emergency service, emergency rescue personnel to assist in the vehicle extrication, extrication of victims involved in Traffic collision, vehicle accidents or railway accidents and cutting large-sized debris of mild metal structures into smaller pieces for extraction of injured/dead victims out from building rubble in earthquake-raged areas, as well as other rescues in small spaces. These tools include cutters, spreaders, and rams. Such devices were first used in 1963 as a tool to free race car drivers from their vehicles after crashes. History The Hurst Rescue Tool was invented by George Hurst, circa 1961, after he viewed a stock car race accident in which it took workers over an hour to remove an injured driver from his car. Previously rescuers often used circular saws for vehicle extrication, but these suffered from several drawbacks. Saws can create Spark_(fire), sparks, which could start a fire, create loud s ...
