In global mining, there are two modes: open-pit and underground mining. For mines with good mineral resource storage conditions, open-pit mining is a good choice. In open-pit mining, the use of excavators for mineral excavation and auxiliary loading is a necessary link. There are various types of excavators, including hydraulic excavators, electric shovel excavators, and pull shovel excavators. This article will sort out the commonly used electric shovel excavator brands in mines.

During the operation of an electric shovel, a giant bucket connected to the bucket rod is used to excavate the earth and rock on the working surface. After the excavation is completed, the bucket is lifted, and the lifting arm is rotated to the unloading position. The latch at the bottom of the bucket is opened to dump the earth and rock onto the loading vehicle, and then the lifting arm is rotated to the working surface to complete a working cycle. In addition, the large tonnage mining truck used in conjunction with the electric shovel has a loading capacity of 180-360 tons.

For large mining shovels (20m³ above), only Taiyuan Heavy Industry, P&H Company from the United States, and BUCYRUS can produce in the world. For 10-20m ³, the power of the Russian UZTM shovel is also relatively strong.

Before 2004, in the cooperation between Taiyuan Heavy Industry and foreign electric shovels, Taiyuan Heavy Industry could only serve as a supporting production factory, and its core technology was still under the control of the United States, resulting in a long-term inability to independently manufacture large electric shovels of over 20 cubic meters. In the subsequent cooperation, the cooperation conditions of the United States will become increasingly stringent. In 2004, an open-pit coal mine in Inner Mongolia urgently needed a 20 cubic meter electric shovel. Taiyuan Heavy Industry took this opportunity to make up its mind and end its cooperation with the United States, starting to tackle core technologies and develop its own giant electric shovel. In February 2005, the first self-developed 20 cubic meter electric shovel was approved for construction by Taiyuan Heavy Industry. Over the following decade, Taiyuan Heavy Industry successfully developed and produced 4-75m ³ Various models of electric shovels. At present, over 1400 electric shovels that are too heavy have been widely used for stripping and loading operations in large open-pit coal mines, iron ore, and non-ferrous metal mines, with dozens of electric shovels exported to more than 10 countries.

In the promotion of heavy electric shovels abroad, MEILIN has played an irreplaceable role. Prior to 2010, in foreign mining markets, especially in Russia, where there were many open-pit mines, P&H shovels from the United States had a basic monopoly on the shovel market. As the exclusive agent of Taiyuan Heavy Industry in Russia, MEILIN, through innovative work models such as service, trade, and after-sales, sold Chinese first 35m³ excavator in 2010. The export of electric shovels to Russia was also the first overseas one, with a production rate even exceeding that of P&H shovels in the United States. It received high praise in Russia and gained a great reputation. In the following decades, more than 40 large WK-20 and WK-35 electric shovels were exported to Russia by MEILIN, making outstanding contributions to the overseas expansion of heavy electric shovels and the creation of international brands. At present, Taizhong Electric Shovel has achieved a market share of over 40% in the Russian market, and has achieved remarkable results in market share and brand building.

Regarding the introduction of electric shovels from P&H Company and Bucyrus Company in the United States, relevant materials and information can be found on many websites, and many of their technologies still require us to learn. At present, P&H shovels in the United States have been acquired by Komatsu. With the rise of Chinese mining excavator brands and their deep participation in market competition, the global price of P&H shovels has also undergone a significant correction.

Overall, there are many enterprises in China that produce mining excavators. However, except for Taiyuan Heavy Industry, which can independently develop large mining excavators, other enterprises mainly cooperate with P&H Company and BUCYRUS in the United States to manufacture, or can only produce small mining excavators. From a long-term development perspective, while learning from advanced foreign technology experience, Chinese mining machinery enterprises still need to continuously improve their core technology research and development capabilities to create truly their own brand products.
