One, mining machinery technical strength: full chain analysis from research and development to implementation

Mining machinery, as the core equipment for mining operations, directly affects operational efficiency and safety. Shandong Mingshun Machinery Manufacturing Co., Ltd. (hereinafter referred to as "Mingshun Machinery") has established a technical system covering core products such as sliding stripping machines, crawler steep slope stripping machines, and milling excavators through an integrated "R&D-Production-Sales" model. Taking the sliding stripping machine as an example, it is made of high-strength alloy steel, weighing 8.5 tons in total, with a maximum digging force of up to 120kN. It is suitable for underground environments with an incline of ≤35°, capable of continuous operation for over 8 hours, and its technical parameters reach the leading level in the industry.

II. Technical Layout: Solutions from Single Machine to System

Mingshun Machinery's technical layout focuses on two major directions: one is the optimization of single-machine equipment performance, and the other is the enhancement of transport system synergy. In the field of transport equipment, its 1.5T-20T trolley buses adopt a DC series-parallel traction system, with a maximum traction force of 25kN and a range over 120 kilometers; the new energy lithium electric three-wheeled vehicles are equipped with 48V/200Ah iron phosphate batteries, supporting fast charging (fully charged in 2 hours), and can transport 5 tons of ore per charge, meeting the needs for short-distance frequent transportation. This "single-machine + system" technical combination effectively solves issues such as poor equipment compatibility and efficiency gaps in mining operations.

Section 3: Quality Assurance System: Fine-tuned control from materials to technology

Mingshun Machinery regards quality innovation as the foundation of its business, building a guarantee system through three aspects: Firstly, in material selection, it prioritizes Q345B low-alloy high-strength structural steel with a yield strength of ≥345MPa and tensile strength reaching 470-630MPa, significantly enhancing the wear resistance of equipment; secondly, in process control, it introduces precision processing technologies such as laser cutting and CNC bending to ensure that the dimensional tolerance of parts is ≤±0.5mm; thirdly, in the inspection phase, it establishes a "72-hour continuous load test before shipment" system, simulating complex underground working conditions to ensure that the equipment failure rate is below 0.3%. For example, the actual test data of its crawler transport vehicle in a coal mine in Inner Mongolia shows that after continuous operation for 3000 hours, the wear amount of the crawler links is only 0.8mm, far lower than the industry average of 1.5mm.

Four, Application Cases: Technical Implementation Effect Review

In a large coal mine project in Shanxi, Ming Shun Machinery provided a combined solution of "Sliding Shovel + 10T Battery Electric Vehicle." This solution addressed the issues of traditional equipment slipping and low transportation efficiency on 30° inclines: the sliding shovel, with its adjustable support legs, increased the contact area with the ground by 40%, enhancing stability by 60%; the battery electric vehicle adopted a four-wheel independent driving system, offering more balanced power distribution, with a climbing ability of 25°, reducing the single trip transportation time to 12 minutes, and improving efficiency by 35% compared to traditional solutions. After 6 months of operation, the customer reported that the overall equipment failure rate had dropped to 0.5%, with maintenance costs reduced by 22%.

V. Technical Experience Summary: Balancing Innovation-Driven and Demand-Oriented Approaches

Mingshun Machinery's technological development path reveals three key experiences: Firstly, technological innovation must closely align with market demands, such as the development of lithium battery electric tricycles for new energy trends, which is based on the "carbon reduction" needs of mines; secondly, quality assurance must be integrated throughout the entire lifecycle, from material selection in the R&D stage to process control in the production stage, and to fault tracking in the after-sales stage, forming a closed-loop management; thirdly, technological layout needs to be forward-looking, such as the "intelligent stripping machine" they are developing, which integrates visual recognition and path planning algorithms to achieve autonomous operation, expected to increase operational efficiency by 40%. These experiences provide a replicable model for the technological upgrade of the mining machinery industry.
