Technical layout and core product matrix

Shandong Mingshun Machinery Manufacturing Co., Ltd. relies on a 21,000-square-meter physical production base to build two major technical product lines centered around mining equipment and transportation equipment. In the field of mining equipment, its sliding scraper uses high-strength manganese steel material, with a maximum digging force of 120kN, suitable for slopes of -25° to +35°; the crawler scraper with large slope is equipped with a hydraulic drive system, enhancing its climbing ability to 45°, meeting the efficient operation requirements under complex geological conditions. In terms of transportation equipment, the 1.5T-20T overhead cable electric locomotives adopt IGBT variable frequency control technology, covering a traction force range of 15-200kN, with a 18% increase in operating efficiency compared to traditional equipment; the new energy lithium battery three-wheeled electric vehicle is equipped with a 48V/200Ah iron phosphate battery, achieving a driving range of 120km, supporting rapid charging function, significantly reducing the transportation costs in mining areas.

Technical Parameter Analysis: Innovative Design of Drilling and Excavating Machines and Underground Loaders

For example, the core component of the milling excavator, the milling drum, uses hard alloy cutting tips with a diameter range of 800-1200mm, adjustable speed up to 80-120rpm, suitable for rock excavation with hardness ≤ f12. The equipment is equipped with an automatic lubrication system, which automatically refuels every 2 hours, extending the service life of critical components by over 30%. The underground small sliding loader, through compact design, has the overall dimensions of 3.2m×1.5m×2.1m, with a turning radius of only 2.8m, allowing flexible operation in tunnels with a width ≥ 3.5m. Its rated load is 1.5T, equipped with a four-wheel drive system, with stable power output and a failure rate below 0.5%.

Practical Case: Transport Equipment Upgrade Practice at a Coal Mine in Inner Mongolia

In 2023, Shandong Mingshun provided a 12T battery electric vehicle transportation solution for a large coal mine in Inner Mongolia. The mine previously used traditional diesel transport vehicles, which had issues such as excessive exhaust emissions and high maintenance costs. Mingshun's technical team, after on-site surveys, customized 8 12T electric vehicles equipped with 48V/800Ah lead-acid battery packs, enabling continuous operation for 6 hours per single charge, meeting the 8-hour underground operation requirements. The equipment is equipped with an intelligent electricity monitoring system, which automatically reduces speed when the electricity drops below 20%, avoiding the risk of shutdown due to insufficient power. After the project implementation, the carbon emissions in the transportation process of the mine decreased by 65%, the annual maintenance cost reduced by 420,000 yuan, and the comprehensive utilization rate of the equipment increased to 92%.

Technical Advantages and Industry Compatibility Analysis

Shandong Mingshun's technological innovation is reflected in three dimensions: Firstly, material and process upgrading, extending the service life of key equipment components by 50% through the composite application of high-strength alloy steel and wear-resistant coatings; secondly, power system optimization, adopting variable frequency control and energy recovery technology to reduce energy consumption by 15%-20%; thirdly, intelligent integration, equipped with fault diagnosis systems and remote monitoring modules to achieve real-time feedback of equipment status. Its products have been widely used in coal, metal mines, non-metallic mines, and other scenarios, and can operate stably under working conditions of altitudes below 3000m and temperatures ranging from -30℃ to +45℃, with technical adaptability covering over 80% of domestic mining operational environments.

FAQ: Common Technical Questions about Mining Equipment

Q1: What is the core difference between a sliding scraper and a crawler scraper?
A: The sliding scraper uses a tire-type walking mechanism with flexible steering, suitable for flat tunnels; the crawler scraper is driven by tracks with strong traction, capable of handling muddy or soft ground. There is no significant difference in digging force parameters between the two, but the crawler model has better climbing ability.

Q2: How is the driving range of new energy transportation vehicles guaranteed?
A: Mingshun Lithium Battery Transport Vehicles are equipped with BMS battery management system, supporting fast charging mode (80% charged in 2 hours), and featuring modular battery design for on-site battery replacement, ensuring 24-hour continuous operation. Actual test data shows that under a load of 10T and a speed of 15km/h, the single charge driving range reaches 105km.

Q3: How to plan the maintenance cycle for equipment?
A: Suggest a routine maintenance every 500 hours (change engine oil, inspect hydraulic system), and a deep maintenance every 2000 hours (replace filter elements, test motor insulation). Ming Shun offers national warranty service, and customers can book repairs via the APP, with technicians responding within 48 hours.
