Loader (equipment)
A loader is a heavy equipment machine used in construction to move or load materials such as soil, rock, sand, demolition debris, etc. into or onto another type of machinery (such as a dump truck, conveyor belt, feed-hopper, or railroad car). There are many types of loader, which, depending on design and application, are variously called a bucket loader, end loader, front loader, front-end loader, payloader, high lift, scoop, shovel dozer, skid-steer, skip loader, tractor loader or wheel loader. Description A loader is a type of tractor, usually wheeled, sometimes on tracks, that has a front-mounted wide bucket connected to the end of two booms (arms) to scoop up loose material from the ground, such as dirt, sand or gravel, and move it from one place to another without pushing the material across the ground. A loader is commonly used to move a stockpiled material from ground level and deposit it into an awaiting dump truck or into an open trench excavation. The loade ...

Surface Mining
Surface mining, including strip mining, open-pit mining and mountaintop removal mining, is a broad category of mining in which soil and rock overlying the mineral deposit (the overburden) are removed, in contrast to underground mining, in which the overlying rock is left in place, and the mineral is removed through shafts or tunnels. In North America, where the majority of surface coal mining occurs, this method began to be used in the mid-16th century and is practiced throughout the world in the mining of many different minerals. In North America, surface mining gained popularity throughout the 20th century, and surface mines now produce most of the coal mined in the United States. In most forms of surface mining, heavy equipment, such as earthmovers, first remove the overburden. Next, large machines, such as dragline excavators or bucket-wheel excavators, extract the mineral. Advantages of surface mining include lower cost and greater safety compared to underground mini ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Komatsu Limited
or is a Japanese multinational corporation that manufactures construction, mining, forestry and military heavy equipment, as well as diesel engines and industrial equipment like press machines, lasers and thermoelectric generators. Its headquarters are in Minato, Tokyo, Japan. The corporation was named after the city of Komatsu, Ishikawa Prefecture, where the company was founded in 1921. Worldwide, the Komatsu Group consists of Komatsu Ltd. and 258 other companies (215 consolidated subsidiaries and 42 companies accounted for by the equity method). Komatsu is the world's second largest manufacturer of construction equipment and mining equipment after Caterpillar. However, in some areas (Japan, China), Komatsu has a larger share than Caterpillar. It has manufacturing operations in Japan, Asia, Americas and Europe. The word ''ko-matsu'' means "small pine tree" () in Japanese. History Komatsu Iron Works was started by Takeuchi Mining Industry as a subsidiary to make indus ...

Guinness World Record
''Guinness World Records'', known from its inception in 1955 until 1999 as ''The Guinness Book of Records'' and in previous United States editions as ''The Guinness Book of World Records'', is a British reference book published annually, listing world records both of human achievements and the extremes of the natural world. Sir Hugh Beaver created the concept, and twin brothers Norris and Ross McWhirter co-founded the book in London in August 1955. The first edition topped the bestseller list in the United Kingdom by Christmas 1955. The following year the book was launched internationally, and as of the 2025 edition, it is now in its 70th year of publication, published in 100 countries and 40 languages, and maintains over 53,000 records in its database. The international franchise has extended beyond print to include television series and museums. The popularity of the franchise has resulted in ''Guinness World Records'' becoming the primary international source for catalo ...

Haul Truck
Haul trucks are off-road, heavy-duty dump trucks specifically engineered for use in high-production mining and exceptionally demanding construction environments. Most are dual axle; at least two examples of tri-axles were made in the 1970s. Haul trucks are denominated by their payload capacity, by weight (variously in tons, tonnes, and kg). Description Most haul trucks have a two-axle design, but two well-known models from the 1970s, the 350T Terex 33-19 "Titan", Terex Titan and 235T WABCO 3200/B, had three axles. Haul truck capacities range from to nearly . An example on the smaller end is the Caterpillar 775 (rated at ). Quarry operations (which produce payloads that have value) are typically employ smaller trucks than mining operations (such as removing undesirable overburden, an expense). Haul trucks can generally be distinguished from standard dump trucks by: * Being far too large to travel legally on public roads * Having a dump body made of exceptionally strong st ...

LeTourneau Technologies
LeTourneau Technologies, Inc. was an American manufacturer of heavy construction equipment founded by R. G. LeTourneau. In 2011, the company was acquired by Joy Global. History R. G. LeTourneau founded R.G. LeTourneau, Inc. in California in 1929, as a contractor of earthmoving equipment, which manufactured products in Longview, Texas. During World War II, the company provided nearly 75% of the Allies' earthmoving equipment. In 1954, it built the first jack-up drilling rig. In 1955, it made the first log-stacker machine. In 1965, the company made the first straddle carrier. LeTourneau had spent the early 1950s perfecting a diesel-electric drivetrain for multi-wheeled heavy-machinery. The system—somewhat similar in concept to the sort used on many locomotives –used a diesel combustion engine to spin an electric generator, which would send its power to hub motors mounted to each wheel of the vehicle. This allowed for multi-wheel-drive without differentials, driveshafts, or ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Joy Global
Joy Global Inc. was a company that manufactured and serviced heavy equipment used in the extraction and haulage of coal and minerals in both underground and surface mining. The company had manufacturing facilities in Alabama, Pennsylvania, Texas, Wisconsin, Australia, Canada, China, France, South Africa, Poland and the United Kingdom.

At the time, Milwaukee was a center of industrial machinery manufacturing at the convergence of three rivers entering Lake Michigan. Among the growing number of machinery manufacturing firms in Milwaukee in the 1870s was a struggling firm known as the Whitehill Sewing Machine Company. Alonzo Pawling and Henry Harnischfeger managed castings patternmaking and gear machining operation ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Engineering Vehicles
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 ...
