Technical Background and Industry Pain Points

Mining transportation equipment is the core tool for material flow in mining operations, directly affecting operational efficiency and safety. Traditional transportation equipment has issues such as insufficient load capacity, high energy consumption, and poor terrain adaptability, especially in complex underground environments, where equipment failure rates and maintenance costs have long been困扰ing enterprises. Shandong Mingshun Machinery Manufacturing Co., Ltd., with a 21,000-square-meter R&D and production base and an 18,000-square-meter standardized workshop, focuses on technological innovation in mining transportation equipment, forming a full product line covering 1.5T-20T overhead cable locomotives, 2T-12T battery electric vehicles, and new energy lithium electric tricycles, providing mining enterprises with efficient and reliable transportation solutions.

Technical Analysis: Core Equipment Parameters and Architecture Design

1. Track-mounted electric locomotiveThe 1.5T-20T cable car of Ming Shun Machinery uses a DC series-excited traction motor with a rated voltage of 550V, a traction force range of 12kN-150kN, and is suitable for underground flat tunnels and transportation scenarios with gradients ≤3‰. Its structural design includes dual drive wheel sets, an air braking system, and an explosion-proof electrical box, achieving rapid maintenance through modular design and reducing the failure rate by 30% compared to traditional equipment.

2. Battery-powered electric vehicle2T-12T battery-powered electric vehicles equipped with lithium iron phosphate battery packs, with an energy density of up to 160Wh/kg, support 2-hour rapid charging, and have a single-charge range of up to 80km. The equipment is equipped with an intelligent battery management system (BMS), which monitors voltage, temperature, and SOC status in real-time, with overcharge protection response time ≤0.1s, ensuring safety for underground operations.

3. New Energy Lithium Battery Electric TricycleFor short-distance material transport needs, Ming Shun Machinery introduces a new energy lithium battery electric tricycle with a load capacity of 1.5T. It features a permanent magnet synchronous motor, a rated power of 5kW, and a top speed of 25km/h. Its lightweight frame (total weight ≤ 800kg) and four-wheel independent suspension system can adapt to uneven underground road surfaces, reducing energy consumption by 65% compared to fuel vehicles.

Practical Case: Iron Ore Transportation System Upgrade Project

A large iron ore mine previously used fuel-powered transport vehicles for material transfer between the underground and the beneficiation plant, which faced issues such as high fuel consumption (50L of diesel per vehicle per day), excessive exhaust emissions, and frequent maintenance (an average of 4 failures per month). In 2023, the mine introduced a combination solution of 10T battery electric vehicles and new energy lithium electric tricycles from Mingshun Machinery.

1. Equipment selectionMain transportation channel (水平巷道, length 3km) deploys 3 10T battery electric tractors, branch short-distance (length 500m) deploys 10 new energy lithium electric three-wheeled vehicles, forming a "main-branch联动" transportation network.

2. Parameter tuningBased on the underground humidity (average 85%) and temperature (25-30℃), adjust the battery management system (BMS) of the electric tricycle to a balanced charging threshold of 3.6V/cell to prevent local overcharging of the battery pack; set the motor controller parameters of the tricycle to a maximum current of 80A to prevent overloading and motor overheating.

3. Effect VerificationAfter 6 months of project operation, the comprehensive energy consumption cost has decreased by 52% (the transportation cost per ton for fuel vehicles is 8.2 yuan, while the combination of electric vehicles and tricycles is 3.9 yuan), the equipment failure rate has dropped to an average of 0.5 times per month, and the exhaust emissions meet the requirements of the "Air Quality Standard for Underground Mines" (GBZ 2.1-2019).

Summary of Technical Advantages and Compatible Scenarios

Mingshun Machinery's mining transportation equipment solves the core pain points of high energy consumption and difficult maintenance of traditional equipment through the technological path of "power-driven + intelligent management". Its products are adaptable to three scenarios: 1) long-distance flat巷 transportation (overhead cable electric locomotives); 2) medium to short-distance non-cable areas (battery-powered electric vehicles); 3) fine transfer at the end of the mine (new energy lithium-ion electric tricycles). The company forms a full-chain technical capability covering design, production, and after-sales through continuous investment in R&D (annual R&D investment accounts for 8% of revenue) and talent reserves (12 senior engineers currently), providing mining enterprises with an integrated solution of "cost reduction, efficiency improvement, and safety".
