Compared with the super electric shovel, the giant shovel is not inferior. The "Big Muskie", built by Bi Seros, is the largest pulling shovel so far on the earth and the largest stride in the history of engineering machinery. It is one of the industrial wonders of human beings. The Loews Corp began developing 4250W spatula for the Muskingum open-pit mine of the central coal company of Ohio in 1967; it cost $25 million (at least $200 million now) and took more than two years until it was built and put into use until May 1969.
Let's take a look at its amazing performance. Big Muskie total weight 12258 tons, total installed power 320000 horsepower (23520 kilowatts), input voltage 13800 volts! The length of the boom is 95 meters. After lowering the boom, the total length of the machine reaches 148.6 meters, which is equivalent to the length of the 1.5 football field. The total width of the machine is 46 meters, wider than that of a two-way 6 lane highway. The roof of the main engine is 20.5 meters away from the ground, equivalent to 7 floors. The top of the A bracket on the top of the computer room is 36.6 meters away from the ground, equivalent to 12 floors. Working state, the top of the boom is 67.8 meters away from the ground, equivalent to 22 floors. Big Muskie has a huge bucket of 8.3 meters long, 7 meters wide and 6.9 meters high. The weight of the bucket reaches 209 tons, which is equivalent to that of Boeing 747. Bucket capacity reached a record 168.2 cubic meters, a shovel enough to dig up more than 300 tons of earthwork. Because of its huge size, the steel giant's walking device no longer uses crawler, but instead uses a stepping device, with a distance of only 161 meters per hour.
The whole 80s is the most glorious period of "Big Muskie". It not only creates a record of the world's single year, but also brings unprecedented wealth to its owners, and has been appearing frequently in various world media, attracting numerous attention. Even once the representative and pride of the American mining machinery manufacturing level, the wind overshadowed the other two of the world's three giant excavators: the old general "Marion 6360" and the land carrier "Bagger 288". In the middle of 80s, "Big Muskie" created an amazing record of more than 46 million cubic meters per year. This is equivalent to the largest open-pit coal mine in China, the Shenhua Zhungeer hedaigou mine, which was 2 times the total amount of mining and stripping in 2007. It was not until 2000 that the record was broken by Germany's "king of excavators" RB292 and RB293.
In 1991, the Muskingum mining area was abandoned and abandoned on the working face due to the huge Big Muskie. From 1969 to 1991, Big Muskie had removed a total of 608 million cubic yards (about 464 million cubic metres) of earth and stone, equivalent to the excavation of 40 Hangzhou, Hangzhou! By 1999, the Muskingum open pit coal mine reclamation work was drawing to a close. Big Muskie still stood alone in the mined out area of the coal mine, and the company decided to demolish it. In order to retain this amazing industrial miracle, thousands of engineering machines all over the world have donated and negotiated with the capital, but the cost and difficulty of the reservation are too huge and the rescue operation failed. In May 1999, with the blasting noise, the steel giant "Big Muskie" walked for a short period of 32 years, and only the bucket was preserved.
In the 70s of last century, two 3270W - type stepping spades were made in Bi Seros, the second largest spatula in the world, second only to the Big Muskie, and the user is the American AMAX coal mine company. The development time of these two machines is basically the same, but the first one is crowded into operation several weeks earlier than the second ones. The first 3270W started its own labor career in 1979 and was housed in the Delta open pit of AMAX company. The second one runs in the Ayrshire open-pit mine. Their performance and parameters are basically the same: the working weight is 7945 tons, the bucket capacity is 135 cubic meters, and the length of the boom is 101 meters, which makes them more like a building rather than a machine. The 3270W is equipped with 12 lifting motors, 8 pulling bucket motors, 6 rotary motors and 6 walking motors, with a total installed power of 18000 horsepower (13230 kW). By 2004, two machines had stopped working after 25 years of work. The company originally intended to sell it, but failed to find a buyer and eventually had to scrapped it.
Marion 8900 is built for the Dugger mine of Peabody, Australia. Its work weight was 6356 tons. At that time, 115 cars were transported to the workplace and assembled for a year, which was put into operation in 1968. It needs 3 people, 76 meters long arm, 119 cubic meters of bucket capacity, and a height equivalent to 14 floors, with 30 motors, 10 cm in diameter and 18270 horsepower (13428 kW) in total power. 8900 the hoist arm was replaced in 1972 and the bucket was replaced. After the Dugger mine was closed, it was transferred to the company's Hawthorn mine, which was later discarded and dismantled in September 2004.
These giant machines, which have never been seen before, have created a brilliant record in the history of human industry. Since the 80s of last century, with the global economic recession, countries have never built such a huge electric shovel and dragline. Even today, the scale of the mining industry is much larger than that of the past. However, the mining equipment used by various countries still failed to break these records. In 2004, Shenhua Zhungeer energy company spent 650 million yuan to order a 8750 step stepping shovel for the black coal mine. This is the largest stride in Asia, with 5300 tons of self weight, 110 meters in length, 90 cubic meters in bucket capacity and 9700 kilowatt in power. In February 2007, it began to be assembled and operated at the end of 2007, and 26 million 60 thousand cubic meters of earthwork were stripped to July 2009. Ensham coal mine in Queensland, Australia, ordered a 8750 dragline to be delivered in 2006.
Human beings were great because of their dreams. From the late fifteenth Century, Da Vinci designed a silt dredger, and by 1835 American William Otis designed the first steam shovel, and then in 1965 Marion made the world's largest electric shovel - Marion 6360. Modern mining machinery has gone through more than 500 years of development history. Behind these super giants, the efforts of countless workers have been condensed. They are working day and night to create brilliant industrial civilization. When will the next huge giant excavator emerge? Let's wait and see.
In the late fifteenth Century, the machinery used to excavate tunnels was recorded in Da Finch's notes.
In 1877, Procter (Ruston Proctor) steam shovel company supplied the steam shovel of the Manchester canal shipping company.
In 1885, Procter Colonial'(Ruston Proctor) made the "Colonial'" steam tractor for Argentina.
This old fellow was made by Marion (Marion) in 1885. It has an arrogant Name: "King's Ditcher". The 77 pairs of steam spade produced by the 1904 from 1908 to 1908 is the main equipment for excavating the Panama Canal.

Marion C type traction steel wheel steam shovel, produced in 1906.
At 4:30 p.m. on May 20, 1913, two steam shovels were successfully assembled in central the Panama Canal, marking the victory of the Panama Canal.
An abandoned steam shovel in Alaska can clearly see the structure of the boiler, water tank, winch, main engine, bucket rod and so on.
Mountaineer is the first super electric shovel built by Marion. It was commissioned in 1956 and decommissioned in 1979. It weighed 2497 tons and the bucket capacity was 40 cubic meters.
1850B, in 1962 to 1974, was the world's second largest electric shovel, nicknamed "Big Brutus", with a cost of $6 million 500 thousand and a weight of 4990 tons, now a museum in West Mineral, Kansas. As long as you remember, the height of man is not high enough for his caterpillar. This is one of the few survivors of the huge electric shovel, and most of the other Big Macs cannot escape the fate of being dismantled and scrapped.
1950B, a peeling type shovel made for Hanna coal mine, was put into use in November 1965, nicknamed the silver shovel "SILVER SPADE", weighing 6350 tons, the capacity of 80 cubic meters, and retiring in 2006.
In early 60s, the Loews Corp launched two 3850B electric shovels, all owned by Peabody (Peabody) coal company, weighing 8165 tons.
Marion Marion 5960 is the second largest stripping shovel produced by Marion, and it was built in 1969. Weighing 8471 tons, the bucket capacity of 96 cubic meters was scrapped and dismantled in 1989.
Now it is the turn of the electric shovel king came out, Marion Marion 6360 was built in 1965, the whole machine weighs 13600 tons, the total power of 21300 horsepower, the bucket capacity of 138 cubic meters, finally dismantled in 1992.
This is Marion's 6360 shovel. In his life, 620 million cubic meters of earth and stone are excavated, enough to build three the Great Wall, or to fill 600 Hangzhou West Lake.
The most famous existing products of Marion should be the "Crawler" transporter made for the NASA, used to carry the shuttle to the launch site, and the tracked chassis is based on the technology of the giant shovel.
The "Big Muskie" giant shovel built by the city of veneros could not have been so lucky. After the demolition and demolition in 1999, only the giant bucket was left for people to remember.
In 2004, Shenhua Zhungeer energy company spent 650 million yuan to order a 8750 step stepping shovel for the black coal mine. This is the largest stride in Asia, with 5300 tons of self weight, 110 meters in length, 90 cubic meters in bucket capacity and 9700 kilowatt in power. In February 2007, it began to be assembled and operated at the end of 2007, and 26 million 60 thousand cubic meters of earthwork were stripped to July 2009.
4100XPC is the flagship product of P&H's electric shovel series mine, and is the latest third generation C machine. It is huge and weighs about 1100 tons. A shovel can hold 104 tons of mineral, and the shovel capacity is 58.5 cubic meters. A few shovels can be filled with huge trucks like CAT 797. The Caterpillar 797 series is the world's largest truck with more than 360 tons of load, and it looks like toys in front of 4100XPC.
The 5700 series, launched in 1991, produced 5 units, developed on the basis of 2800, is the largest electric shovel produced by P&H company, and the input voltage is 14400V. It has 4 bucket elevator motor, 2 propulsion motor and 4 rotary motor, the length of the crane arm is 21m, the whole machine quantity: 1667t tons, loading capacity: 9975kW, shovel Bucket capacity: 61m3.
The 3 cubic meter electric shovel made by the Soviet Union used in the Haizhou open-pit coal mine of Fuxin, Liaoning, was made by the heavy machinery factory of the Soviet Union Ural.
The Pingshuo opencast coal mine in Pingshuo, Shanxi, was designed and built by China Coal Group. It was set up in 1994 and started in December 1999, with a total investment of 4 billion 800 million yuan and 15 million tons of raw coal annually, including 1 open-pit mines, 2 coal mines, 1 15 million tons coal preparation plant and 21 kilometer railway special line. The main coal mining can be divided into 3 layers, with an average thickness of about 30 meters, with a depth of 100-200 meters and a total reserve of 14.5 billion tons. In June 2002, an Jialing open pit coal was put into trial production, producing 3 million 310 thousand tons of raw coal per year and 15 million 10 thousand tons in 2005. In March 18, 2006, the An Jia Ling coal mine was formally put into operation. At present, it has become one of the largest and the most modern coal production bases in China.
In 1988, Bagger 288 moved to a new workplace 22 kilometres away. The cost of moving was one hundred and fifty million Mark. But its owner, RWE, thinks that the cost of moving is far less than the cost of demolition giant and installation giant.
