Power Shovel
A power shovel (also stripping shovel or front shovel or electric mining shovel or electric rope shovel) is a bucket-equipped machine, usually electrically powered, used for digging and loading earth or fragmented rock and for mineral extraction. Power shovels are a type of rope/cable excavator, where the digging arm is controlled and powered by winches and steel ropes, rather than hydraulics like in the more common hydraulic excavators. Basic parts of a power shovel include the track system, cabin, cables, rack, stick, boom foot-pin, saddle block, boom, boom point sheaves and bucket. The size of bucket varies from 0.73 to 53 cubic meters. Design Power shovels normally consist of a revolving deck with a power plant, drive and control mechanisms, usually a counterweight, and a front attachment, such as a crane ("boom") which supports a handle ("dipper" or "dipper stick") with a digger ("bucket") at the end. The term "dipper" is also sometimes used to refer to the handle and digg ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Marion 6360
Marion 6360, also known as ''The Captain'', was a giant power shovel built by the Marion Power Shovel company. Completed in 1965, it was one of the largest land vehicles ever built, exceeded only by some dragline and bucket-wheel excavators. The shovel originally started work with Southwestern Illinois Coal Corporation, but the owners were soon bought out by Arch Coal. Everything remained the same at the mine except for the colors which were changed to red, white, and blue. The shovel worked well for Arch Coal until September 9, 1991, when a fire broke out in the lower works of the shovel. It was caused by a burst hydraulic line that was spraying the hot fluids on an electrical relay panel. This fire caused a great deal of damage to both the lower works and machine house. Afterwards, engineers from both Arch and Marion Power Shovel surveyed the damage and deemed it too great to repair, and the machine was scrapped one year later in the last pit it dug. The only Marion shovel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hulett
The Hulett was an ore unloader that was widely used on the Great Lakes of North America. It was unsuited to tidewater ports because it could not adjust for rising and falling tides, although one was used in New York City. History The Hulett was invented by George Hulett of Conneaut, Ohio, in the late 19th century; he received a patent for his invention in 1898. The first working machine was built the following year at Conneaut Harbor. It was steam powered, successful, and many more were built along the Great Lakes, especially the southern shore of Lake Erie to unload boats full of taconite from the iron mines near Lake Superior. John W. Ahlberg converted the Huletts in Conneaut to electricity in the 1920's. Substantial improvements were later made on the design by Samuel T. Wellman. The Hulett machine revolutionised iron ore shipment on the Great Lakes. Previous methods of unloading lake freighters, involving hoists and buckets and much hand labor, cost approximately 18¢/ton. ...

Steam Shovel
A steam shovel is a large steam-powered excavating machine designed for lifting and moving material such as rock and soil. It is the earliest type of power shovel or excavator. Steam shovels played a major role in public works in the 19th and early 20th century, being key to the construction of railroads and the Panama Canal. The development of simpler, cheaper diesel-powered shovels caused steam shovels to fall out of favor in the 1930s. History Origins and development Grimshaw of Boulton & Watt devised the first steam-powered excavator in 1796. In 1833 William Brunton patented another steam-powered excavator which he provided further details on in 1836. The steam shovel was invented by William Otis, who received a patent for his design in 1839. The first machines were known as 'partial-swing', since the boom could not rotate through 360 degrees. They were built on a railway chassis, on which the boiler and movement engines were mounted. The shovel arm and driving ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Marion Power Shovel
Marion Power Shovel Company was an American firm that designed, manufactured and sold steam shovels, power shovels, blast hole drills, excavators, and dragline excavators for use in the construction and mining industries. The company was a major supplier of steam shovels for the construction of the Panama Canal. The company also built the two crawler-transporters used by NASA for transporting the Saturn V rocket and later the Space Shuttle to their launch pads. The company's shovels played a major role in excavation for Hoover Dam, the Holland Tunnel and the extension of the Number 7 subway line to Main Street in Flushing, Queens. Founded in Marion, Ohio in August, 1884 by Henry Barnhart, Edward Huber and George W. King as the Marion Steam Shovel Company, the company grew through sales and acquisitions throughout the 20th century. The company changed its name to Marion Power Shovel Company in 1946 to reflect the industry's change from steam power to diesel power. The ...

Excavator
Excavators are heavy construction equipment consisting of a boom, dipper (or stick), bucket and cab on a rotating platform known as the "house". The house sits atop an undercarriage with tracks or wheels. They are a natural progression from the steam shovels and often mistakenly called power shovels. All movement and functions of a hydraulic excavator are accomplished through the use of hydraulic fluid, with hydraulic cylinders and hydraulic motors. Due to the linear actuation of hydraulic cylinders, their mode of operation is fundamentally different from cable-operated excavators which use winches and steel ropes to accomplish the movements. Terminology Excavators are also called diggers, JCBs (a proprietary name, in an example of a generic trademark), mechanical shovels, or 360-degree excavators (sometimes abbreviated simply to "360"). Tracked excavators are sometimes called "trackhoes" by analogy to the backhoe. In the UK and Ireland, wheeled excavators are somet ...

Dragline
A dragline excavator is a piece of heavy equipment used in civil engineering and surface mining. Draglines fall into two broad categories: those that are based on standard, lifting cranes, and the heavy units which have to be built on-site. Most crawler cranes, with an added winch drum on the front, can act as a dragline. These units (like other cranes) are designed to be dismantled and transported over the road on flatbed trailers. Draglines used in civil engineering are almost always of this smaller, crane type. These are used for road, port construction, pond and canal dredging, and as pile driving rigs. These types are built by crane manufacturers such as Link-Belt and Hyster. The much larger type which is built on site is commonly used in strip-mining operations to remove overburden above coal and more recently for oil sands mining. The largest heavy draglines are among the largest mobile land machines ever built. The smallest and most common of the heavy type weigh ...

The Silver Spade
The Silver Spade was a giant power shovel used for strip mining in southeastern Ohio. Manufactured by Bucyrus-Erie, South Milwaukee, Wisconsin, the model 1950-B was one of two of this model built, the other being the GEM of Egypt. Its sole function was to remove the earth and rock overburden from the coal seam. Attempts to purchase and preserve the shovel from Consol to make it the centerpiece of a mining museum exhibit for $2.6 million fell short, and the shovel was dismantled in February 2007.

The GEM Of Egypt
The GEM of Egypt was a power shovel used for strip mining. Built in 1966, the machine had worked in the Egypt Valley coalfield, GEM being an acronym for “Giant Earth Mover” or “Giant Excavating Machine”. It was one of only two Bucyrus-Erie 1950-B shovels built and one of two to use the knee action crowd, licensed from Marion Power Shovel in exchange to Marion's use of BE's cable crowd patent. Operational history The GEM had a 170' boom and a 130 cubic yard bucket which enabled it to dig roughly 200 tons per 'bite'. The machine began work in January, 1967 for Hanna Coal, and was later purchased by Consolidated Coal in "Little Egypt Valley" near Barnesville, Ohio. The area was also where the GEM got its name. The GEM of Egypt was one of three in the service of the Hanna Coal Company, which by 1970, had been strip mining in Ohio for decades. The other two power shovels were ''The Tiger'' and ''The Mountaineer''. Of the three, the GEM of Egypt was the largest of the power ...
