I. Technical Layout and R&D Strength: Strengthening the Innovation Foundation of Mining Machinery

Shandong Mingshun Machinery Manufacturing Co., Ltd. is located in Qufu, Shandong, with a 21,000-square-meter factory area and 18,000-square-meter modern workshop, constructing a complete technical system integrating research and development, production, and sales. The company focuses on the field of mining machinery, forming two major technical sectors centered around mining equipment and transportation equipment, covering more than 10 types of core products such as sliding scraper, crawler scraper with steep slope, drilling machine, and 1.5T-20T overhead trolley. Its technical layout presents three major characteristics:

1. Technological Integration and InnovationBy absorbing advanced technologies from home and abroad, integrating cutting-edge technologies such as hydraulic control, intelligent sensing, and modular design into product development. For example, its sliding scraper uses high-strength alloy steel material, combined with an optimized hydraulic system, achieving a maximum digging force of 120kN, a 20% increase over traditional models.

2. Scenario-adaptedFor complex underground working conditions, a crawler scraper with a large slope angle has been developed, supporting a maximum climbing angle of 35°. It is equipped with explosion-proof motor and sealed structure, meeting the safety requirements of coal mines, metal mines, and other scenarios.

3. Green technology upgradeIntroducing new energy lithium battery electric three-wheeler for transportation equipment, equipped with 48V/200Ah iron phosphate batteries, offering a range of 80 kilometers, reducing operating costs by 60% compared to fuel models, and featuring zero emissions in compliance with mine environmental protection requirements.

II. Core Product Technology Analysis: Driving Industry Applications with Performance and Reliability

1. Technical Breakthrough in Mining Equipment

For example, the technical parameters of the milling excavator reflect precise design:

• Milling and挖掘轮 diameter: 800mm, suitable for working scenarios with tunnel cross-sectional area ≥ 2.5m².
• Milling Excavation Power: 75kW, equipped with variable frequency speed regulation technology, achieving stepless speed variation from 0 to 15 rpm.
• Dust Collection System: Equipped with a negative pressure dust removal device, dust concentration is controlled below 10mg/m³, significantly lower than the national standard.

In a certain iron ore project, the equipment operated continuously for 1200 hours without any failure, improving the traditional blasting excavation efficiency by 3 times, reducing the excess tunnel excavation by 40%, and significantly lowering the later support cost.

2. Intelligent upgrading of transportation equipment

Technical highlights of the 12T battery-powered electric vehicle include:

• Power System: Equipped with a 48V/800Ah lead-acid battery pack, supporting continuous operation for 8 hours, charging time ≤6 hours.
• Control System: Integrated PLC intelligent control module, realizing functions such as speed regulation, fault self-inspection, and remote monitoring.
• Safety Design: Equipped with triple safety mechanisms including anti-skid braking, overload protection, and emergency power cut-off, verified by the safety standard for explosion-proof diesel engine trolley vehicles used in coal mines, MT/T 960-2005.

In the transportation link of a coal mine, after this vehicle model replaced the original fuel vehicles, it reduced carbon dioxide emissions by 120 tons annually and cut maintenance costs by 55%, becoming a typical case of green mine construction.

Section 3: Industry Application Cases: Technical Implementation Effects and Experience Summary

1. Case 1: Efficient Mining Under Metal Mines

A certain copper mine project is facing challenges of steep tunnel grades and narrow working spaces. Shandong Mingshun offers a combined solution of crawler scraper for steep grades + small underground sliding loader.

• Track scraper: Maintains stable operation in slippery tunnels by optimizing the ground pressure ratio of the tracks (0.12 MPa).
• Sliding Loader: Equipped with a quick-change attachment interface, capable of switching tools such as crushers, log grabbers, etc., to achieve "one machine, multiple uses."
• Collaborative Efficiency: The combined operation of two devices increases the mining output per shift from 80 tons to 150 tons, and the comprehensive utilization rate of the equipment is improved to 85%.

2. Case 2: Construction of Green Transportation System for Coal Mines

A large coal mine introduces 12T battery electric tractors and new energy lithium three-wheeled vehicles from Shandong Mingshun to respond to the "Dual Carbon" goal.

• Transport route planning: Design an energy supply network of "fixed charging stations + mobile charging vehicles" based on the underground tunnel layout.
• Data Management: Real-time collection of data on power, location, and operational status through vehicle-mounted sensors to optimize scheduling strategies.
• Emission Reduction Achievements: After one year of project implementation, transportation emissions were reduced by 62%, and the project was recognized as a provincial green mine demonstration project.

4. Technical Development Concept: Drive industry upgrade with quality and innovation

Shandong Mingshun Machinery always regards "technology-oriented enterprise" as its core strategy, continuously enhancing its competitiveness through three aspects:

• R&D InvestmentEach year, allocate 8% of revenue to new technology research and development, and jointly establish a "Mining Machinery Joint Laboratory" with universities.
• Talent ReserveEstablish a technical team led by 20 senior engineers, including 8 with over 10 years of industry experience.
• Standard SettingParticipated in drafting 3 industry standards such as "Safety Technical Specification for Mining Gravel Dredgers," promoting standardized development of the industry.

In the future, the company plans to expand its layout in fields such as intelligent control and hydrogen energy power, striving to achieve over 60% intelligent coverage of core products by 2025, and providing more efficient, safe, and environmentally friendly technical solutions for the mining industry.

FAQ: Common Questions about Mining Machinery Technology

Q1: How to choose between sliding bucket wheel loaders and crawler bucket wheel loaders?
A: Sliding models are suitable for scenarios with smaller tunnel cross-sections (≤3m²) and frequent turns; crawler models are more applicable to working environments with steep slopes (≥25°) and slippery surfaces.

Q2: Can the range of new energy transportation equipment meet long-distance operations?
A: Taking a 12T battery-powered electric vehicle as an example, its 800Ah battery pack supports round-trip transportation of 5 kilometers, and when paired with a mobile charging vehicle, it can achieve continuous 24-hour operation.

Q3: What is the maintenance cycle for mining machinery?
A: Routine maintenance (such as hydraulic oil replacement, filter cleaning) is recommended every 500 hours; the lifespan of core components (such as motors, reducers) usually exceeds 8000 hours, and the specific duration should be adjusted according to the working conditions.
