Caterpillar D11
The Caterpillar D11T is a large bulldozer, manufactured by Caterpillar Inc. in East Peoria, Illinois, and mainly used in the mining industry. Primarily designed as a bulldozer, it is also used for push-loading scrapers, and ripping rock overburden. History D11N The D11N was introduced in February 1986 to replace the D10. The D11N had some major improvements over the D10: it includes a bigger track and blade, and a longer track by . The U blade was just under long and high. This increased the blade capacity to . The D11N's weight was . It was powered by a , 3508 V-8 diesel engine. The D11N's improvements made it over 10 percent more productive than the D10. In 1987 a hydraulically powered impact ripper was added to the D11N which raised the weight up to . This would become known as the D11N Impact Ripper. D11R & D11R Carrydozer The D11R and D11R Carrydozer were introduced in Las Vegas, Nevada, at MINExpo International in 1996. Both were and that would be increased to later i ...

Caterpillar Track
Continuous track is a system of vehicle propulsion used in tracked vehicles, running on a continuous band of treads or track plates driven by two or more wheels. The large surface area of the tracks distributes the weight of the vehicle better than steel or rubber tires on an equivalent vehicle, enabling continuous tracked vehicles to traverse soft ground with less likelihood of becoming stuck due to sinking. Modern continuous tracks can be made with soft belts of synthetic rubber, reinforced with steel wires, in the case of lighter agricultural machinery. The more common classical type is a solid chain track made of steel plates (with or without rubber pads), also called caterpillar tread or tank tread, which is preferred for robust and heavy construction vehicles and military vehicles. The prominent treads of the metal plates are both hard-wearing and damage resistant, especially in comparison to rubber tyres. The aggressive treads of the tracks provide good trac ...

Aggregate (geology)
In the Earth sciences, aggregate has three possible meanings. In mineralogy and petrology, an aggregate is a mass of mineral crystals, mineraloid particles or rock particles. Examples are dolomite, which is an aggregate of crystals of the mineral dolomite, and ''rock gypsum'', an aggregate of crystals of the mineral gypsum. Lapis lazuli is a type of rock composed of an aggregate of crystals of many minerals including lazurite, pyrite, phlogopite, calcite, potassium feldspar, wollastonite and some sodalite group minerals. In the construction industry, an aggregate (often referred to as a construction aggregate) is sand, gravel or crushed rock that has been mined or quarried for use as a building material. In pedology, an aggregate is a mass of soil particles. If the aggregate has formed naturally, it can be called a ped; if formed artificially, it can be called a clod.

Tractors
A tractor is an engineering vehicle specifically designed to deliver a high tractive effort (or torque) at slow speeds, for the purposes of hauling a trailer or machinery such as that used in agriculture, mining or construction. Most commonly, the term is used to describe a farm vehicle that provides the power and traction to mechanize agricultural tasks, especially (and originally) tillage, and now many more. Agricultural implements may be towed behind or mounted on the tractor, and the tractor may also provide a source of power if the implement is mechanised. Etymology The word ''tractor'' was taken from Latin, being the agent noun of ''trahere'' "to pull". The first recorded use of the word meaning "an engine or vehicle for pulling wagons or plows" occurred in 1896, from the earlier term " traction motor" (1859). National variations In the UK, Ireland, Australia, India, Spain, Argentina, Slovenia, Serbia, Croatia, the Netherlands, and Germany, the word "tractor" us ...

Heavy Equipment (construction)
Heavy equipment or heavy machinery 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 in ''De architectura'' when it was powered via human or animal labor. Heavy equipment functions through the mechanical advantage of a simple machine, the ratio between input force applied and force exerted is multiplied, making tasks which could take hundreds of people and weeks of labor without heavy equipment far less intensive in nature. Some equipment uses hydraulic drives as a primary source of motion. The term "plant" is used to refer to any mobile type of heavy machinery. History The use of heavy equipment has ...

Civil Engineering
Civil engineering is a professional engineering discipline that deals with the design, construction, and maintenance of the physical and naturally built environment, including public works such as roads, bridges, canals, dams, airports, sewage systems, pipelines, structural components of buildings, and railways. Civil engineering is traditionally broken into a number of sub-disciplines. It is considered the second-oldest engineering discipline after military engineering, and it is defined to distinguish non-military engineering from military engineering. Civil engineering can take place in the public sector from municipal public works departments through to federal government agencies, and in the private sector from locally based firms to global Fortune 500 companies. History Civil engineering as a discipline Civil engineering is the application of physical and scientific principles for solving the problems of society, and its history is intricately linked to advances in t ...

Benjamin Holt
Benjamin Leroy Holt (January 1, 1849 – December 5, 1920) was an American businessman and inventor who patented and manufactured the first practical crawler-type tread tractor. The continuous-type track is used for heavy agricultural and engineering vehicles to spread the weight over a large area to prevent the vehicle from sinking into soft ground. He founded with his brothers the Holt Manufacturing Company. Early life The youngest of four brothers and eleven siblings, the children of William Knox Holt and first, Eliza Jane Virgin, and later Harriet Parker Ames of Concord, New Hampshire. William Knox Holt owned a sawmill that made hardwood for wagon and coach construction. In 1864, Benjamin's brother Charles H. Holt arrived in San Francisco, California where he founded C. H. Holt and Co. The company produced wooden wheels for wagons and, later on, steel streetcar wheels. Brothers William Harrison Holt and Ames Frank Holt arrived in 1871. The company sold hardwood, lumber, wag ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Acco Super Bulldozer
The Acco Super Bulldozer is the largest and most powerful tracked bulldozer ever made. It was built in Portogruaro in northern Italy by the Umberto Acco company. The Acco super bulldozer was constructed mainly of Caterpillar parts; however, many other components were specially adapted. The dozer blade, for example, is bigger than anything Caterpillar has ever made. This bulldozer has a gross weight of 183 tonnes and is powered by two Caterpillar engines placed horizontally opposed, which deliver a total combined output of . The super bulldozer has a blade that is wide and high, whilе the total length of the bulldozer is over , from the tip of the blade to the ripper on the rear. The ripper alone is about tall, being powered by huge hydraulic rams. This bulldozer was initially built to be exported to Libya in the early 1980s to help in land development.

Komatsu D575
The Komatsu D575A is a tractor crawler produced in a 'SR' or Super Ripper bulldozer/ripper configuration, or as a dedicated bulldozer in the form of the 'SD' or Super Dozer. Both models can move of material per pass using the standard blade. The D575A-3 SD Super Dozer can move of material per pass if equipped with an optional blade. The D575A-3 can dig to a maximum depth of using its single-shank ripper. Commonly referred to as the 'world's largest production bulldozer', the D575A series bulldozers were produced by Komatsu Ltd. in Osaka, Japan. Surface mine operators in the United States, Australia and Japan were the primary users of the D575A, although they were sometimes used in heavy construction applications and quarries as well. Development Komatsu first showed a bulldozer prototype, the D555A, to the public at the Conexpo equipment exhibition in Houston, Texas in 1981. Due to economic conditions at the time, development was stalled for much of the 1980s. A successor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
