Loader (equipment)
A loader is a Heavy equipment (construction), heavy equipment machine used in construction to move or load materials such as soil, Rock (geology), 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, front loader, front-end loader, payloader, high lift, scoop, shovel, skip loader, wheel loader, or skid-steer. Description A loader is a type of tractor, usually wheeled, Tracked loader, sometimes on tracks, that has a front-mounted wide Bucket (machine part), 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 tru ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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. The pros of surface mining are that it has a lower financial cost and is a lot safer than undergrou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Komatsu Limited
or () is a Japanese multinational corporation that manufactures construction, mining, forestry and military 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 industrial t ...

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 reference book published annually, listing world records both of human achievements and the extremes of the natural world. The brainchild of Sir Hugh Beaver, the book was co-founded by twin brothers Norris and Ross McWhirter in Fleet Street, London, in August 1955. The first edition topped the best-seller list in the United Kingdom by Christmas 1955. The following year the book was launched internationally, and as of the 2022 edition, it is now in its 67th year of publication, published in 100 countries and 23 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 authority o ...

Haul Truck
Haul trucks are off-highway, rigid dump trucks specifically engineered for use in high-production mining and heavy-duty construction environments. Haul trucks are also used for transporting construction equipment from job site to job site. Some are multi-axle in order to support the equipment that is being hauled. Description Most haul trucks have a two-axle design, but two well-known models from the 1970s, the 350T Terex Titan and 235T Wabco 3200/B, had three axles. Haul truck capacities range from to . Large quarry-sized trucks range from . A good example of this is the Caterpillar 775 (rated at ). Quarry operations are typically smaller than, say, a gold/copper mine, and require smaller trucks. Ultra class The largest, highest-payload-capacity haul trucks are referred to as ''ultra class'' trucks. The ultra class includes all haul trucks with a payload capacity of or greater. , the BelAZ 75710 has the highest payload capacity, . Rear-eject A rear-eject configuration is ...

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, also the founder of LeTourneau University, founded R. G. LeTourneau, Inc. in 1929 in California as a contractor of earthmoving equipment. LeTourneau manufactured products in Longview, Texas. During World War II, the company provided 70% 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 sort of diesel-electric drivetrain for multi-wheeled heavy-machinery. The system – somewhat similar in concept to the sort used on many locomotives – used a combustion engine to spin an electric generator. This generator would send its power to hub motors mounted to each wheel of the vehicle, allowing for multi-wheel- ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Alonzo Pawling and Henry Harnischfeger managed castings patternmaking and gear machining operations within th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Engineering Vehicles
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 ha ...
