Box Crib
A box crib or cribbing is a temporary wooden structure used to support heavy objects during construction, 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 Cribbing has largely been replaced by hydraulic shoring in modern mining applications.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 footprint of the crib to its height, ...

Hydraulic Rescue Tools
Hydraulic rescue tools, also known as jaws of life, are used by emergency rescue personnel to assist in the extrication of victims involved in vehicle accidents, 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 sparks, which could start a fire, create loud sounds, stress the victim(s), and often cut slowly. Alternatively, rescuers could try to pry open the vehicle doors with a crowbar or Halligan bar, but this could compromise the stability of the vehicle, or injure the victims further. In comparison, hydraul ...

Rescue
Rescue comprises responsive operations that usually involve the saving of life, or the urgent treatment of injuries after an accident or a dangerous situation. Tools used might include search and rescue dogs, mounted search and rescue horses, helicopters, the "jaws of life", and other hydraulic cutting and spreading tools used to extricate individuals from wrecked vehicles. Rescue operations are sometimes supported by rescue vehicles operated by rescue squads. Rescue is a potent theme in human psychology, both from mortal perils and moral perils, and is often treated in fiction, with the rescue of a damsel in distress being a notable trope. Psychoanalyst Sigmund Freud introduced the concept of "rescue fantasies" by men pursuing "fallen women" in his 1910 work "A Special Type of Choice of Object Made by Men"; Freud's insight into this aspect of male psychology might retain merit, though his proposed Oedipus complex used to frame this concept is no longer in vogue.

Museum Of Science And Industry (Chicago)
The Museum of Science and Industry (MSI) is a science museum located in Chicago, Illinois, in Jackson Park, in the Hyde Park neighborhood between Lake Michigan and The University of Chicago. It is housed in the former ''Palace of Fine Arts'' from the 1893 World's Columbian Exposition. Initially endowed by Julius Rosenwald, the Sears, Roebuck and Company president and philanthropist, it was supported by the Commercial Club of Chicago and opened in 1933 during the Century of Progress Exposition. Among the museum's exhibits are a full-size replica coal mine, captured during World War II, a model railroad, the command module of Apollo 8, and the first diesel-powered streamlined stainless-steel passenger train (''Pioneer Zephyr''). History The Palace of Fine Arts (also known as the Fine Arts Building) at the 1893 World's Columbian Exposition was designed by Charles B. Atwood for D. H. Burnham & Co. During the fair, the palace displayed paintings, prints, drawing, sculpture, an ...

German Submarine U-505
''U-505'' is a German Type IXC submarine built for Germany's ''Kriegsmarine'' during World War II. She was captured by the U.S. Navy on 4 June 1944. In her uniquely unlucky career with the ''Kriegsmarine'', she had the distinction of being the "most heavily damaged U-boat to successfully return to port" in World War II on her fourth patrol, and the only submarine in which a commanding officer took his own life in combat conditions on her tenth patrol, following six botched patrols. She was captured on 4 June 1944 by United States Navy Task Group 22.3 (TG 22.3), one of six U-boats that were captured by Allied forces during World War II. All but one of ''U-505''s crew were rescued by the Navy task group. The submarine was towed to Bermuda in secret and her crew were interned at a US prisoner of war camp, where they were denied access to International Red Cross visits. The Navy classified the capture as top secret and prevented the Germans from discovering it. In 1954, ''U-505'' ...

Shoring
Shoring is the process of temporarily supporting a building, vessel, structure, or trench with shores (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 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 shores, shoring beams, and timber jacks ...

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 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 (aka cha ...

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 it 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 climat ...

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 countless kinds of farm implements that they tow or operate. Diverse arrays of equipment are 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. History The Industrial Revolution With the coming of the Industrial Revolution and the development of more complicated machines, farming methods took a great leap forward. Instead of harvesting grain by hand with a sharp blade, wheeled machines cut a continuous swath. Instead of threshing the grain by beating it with sticks, threshing machines separated the seeds from the heads and stalks. The first tractors appeared in the late 19th century. Steam power Power for agricultural machinery was originally supplied by ...
