Demonstrate the power of "Made in China".
Some time ago, in the "Independent Equipment" of the "Super Equipment" series broadcast by CCTV, a detailed report was made on the large-scale application of domestic mining equipment in the mines of Zhunneng Group.
From the "Independent Equipment" of the "Super Equipment" series broadcast by CCTV
In order to support the development of national industry and achieve high-quality development, Zhunneng Group has started the localization development of imported equipment and accessories since 1995.
Especially in recent years, while making full use of foreign advanced large-scale mining equipment, Zhunneng Group has actively cooperated with domestic scientific research institutes and equipment manufacturers to carry out high-end development and localization of mining equipment.
Now, Zhunneng Group is not only a test ground for the research and development of large-scale mining equipment, but also an incubator for the high-end development of domestic equipment, and a "T-catwalk" for domestic equipment to show itself!
XCMG's XE7000 hydraulic excavator is up to 235 meters, width 909 meters, 944 meters, the maximum horizontal push distance on the ground is 469 meters, the maximum excavation radius is 167 meters, dead weight 700 tons. XCMG 700-ton excavator, as the largest tonnage mining hydraulic excavator independently developed and produced by China's local brand, also has a milestone significance in the development history of China's open-pit mining equipment.
With the "Big Mac" loading capacity of a bucket of 60 tons of coal and the power of nearly 30 family cars, it has become the "master equipment" of the coal mine in one "move", and has been recognized by the person in charge of the mining area as "beyond imagination and trust".
The birth of "Shenzhou No. 1 Digging" XE7000 has made China the fourth country with R&D and manufacturing of hydraulic excavators of more than 700 tons after Germany, Japan and the United States, with more than 60 independent patents, and has achieved a breakthrough in the centralized application of key core technologies for the first time in the field of super-large ton hydraulic excavators in China, which is of milestone significance in the development history of China's super open-pit mining equipment.
This is the WK-55 electric shovel, manufactured by Taiyuan Heavy Industry Co., Ltd., after being made, the machine is nearly 22 meters high, which is equivalent to the height of a 7-story building;The total weight is 1,400 tons, which is equivalent to the total weight of 70 train wagons combined;Its bucket capacity is 55 cubic meters, the annual production capacity can reach 12 million cubic meters, and the monthly excavation is 1 million cubic meters.
Aerospace Heavy Industry's HT3363 mining truck is 158m, width 95m, height 79m, self-weight 237 tons, load 363 tons, load-to-weight ratio up to 153, which is also one of the largest mining trucks in Zhunneng Group at present.
At present, Zhunneng Group has successfully tried the WK20 electric shovel, WK35 electric shovel, Xiangdian Heavy Equipment 300-ton SF35100 mining truck, MCC Jingcheng 363-ton HMTK600B mining truck, Aerospace Heavy Industry 363-ton HT3363 mining truck, XCMG 550-horsepower GR5505 grader and Shantui's 900-horsepower SD-90 bulldozer. With the strong support of Zhunneng Group, domestic mining equipment and accessories have found a stage to show their talents in the open-pit coal mine of Zhunneng Group.
The 25 years from 1995 when coal production was on the right track to the present is an important stage for Zhunneng Group to move from high-speed growth to high-quality development, and it is also a critical period for Zhunneng Group's domestic development work to move from the primary stage of pure substitution to the advanced stage of design, transformation and independent research and development.
The whole machine replaces imports
1.From the WK20 electric shovel with a bucket capacity of 23 cubic meters to the current WK55 electric shovel with a capacity of 58 cubic meters.
2.From the 108-ton SF3102 truck to the current 363-ton truck.
Accessories instead of imports
From the simple components such as the rope pull switch and the bucket square pin of the electric shovel bucket of the early belt conveyor to the core components such as the engine, electric wheels, MT5500 truck electrical system and 395B electric shovel electrical system of the 930E truck, it has gradually filled the domestic gap and broken the monopoly of imported equipment.
During this period, Zhunneng Group has used domestic equipment to replace imports with more than 73 sets, with a total value of about 1.5 billion yuanA total of 3,935 imported accessories have been developed, 54,262 pieces, and the proportion of domestic accessories purchased in the past five years to replace imports is 24%, which can save 200 million yuan in parts procurement costs every year.
In the past 25 years, the localization development has gradually improved the passive situation of technology being controlled by others, high quality, unstable supply cycle, and rising maintenance costs year by year, which has not only helped Zhunneng Group to reduce costs and increase efficiency, but also boosted the development of national mining equipment, and improved the international competitiveness and influence of "Made in China".
Nowadays, the localization of equipment parts can not only reduce the cost pressure and inventory of Zhunneng Group, but also improve production efficiency.
As a central enterprise and a representative of the advanced technology of open mining equipment, Zhunneng Group has a heavy responsibility
It is incumbent upon us to promote high-end development
The original intention of equipment localization remains unchanged
Zhunneng - to speak for localized equipment
