I. Company's Technical Background and Mine Equipment Layout

Shandong Mingshun Machinery Manufacturing Co., Ltd. is located in Qufu, Shandong. As an integrated entity focusing on research and development, production, and sales, it covers an area of 21,000 square meters, with 18,000 square meters of standardized workshops, specializing in the field of mining machinery for over a decade. Its technological layout is centered around "mining equipment" and "transportation equipment," forming a comprehensive product system covering the entire underground operation process, including sliding scraper machines, crawler scraper machines with steep gradients, milling excavators, etc., as well as 1.5T-20T overhead cable locomotives, new energy lithium battery electric tricycles, and other transportation equipment, which are adaptable to different mine conditions and operational requirements.

II. Technical Analysis of Mining Equipment: Sliding Shovel and Crawler Steep Slope Shovel

1. Technical Parameters and Scene Adaptability of Sliding Shovel Dumper
Sliding scraper model MS-800, rated power 55kW, maximum digging force 120kN, suitable for underground level tunnels and narrow tunnels with slopes ≤15°. Its core advantage lies in the 360° rotating chassis and telescopic boom design, allowing flexible adjustment of working angles, with an operating efficiency of up to 200m³/h per shift, a 40% increase over traditional equipment. In practical operation, attention should be paid to: check the hydraulic system pressure before operation (standard value 16MPa), avoid overloading; regularly clean the ore between the bucket teeth to prevent increased wear.

2. Track-type large gradient scraper technology breakthrough
For steep slope mines with an inclination greater than 25°, Mingshun Machinery has developed the MS-1200F tracked model, featuring a high-strength tracked undercarriage (contact pressure ≤ 0.12MPa) and dual hydraulic motors for driving, achieving a climbing ability of up to 35°. The cutter head speed is adjustable (0-80rpm) and suitable for hard rock (f≤8) and soft soil mixed strata. Case: In a gold mine steep slope tunnel project, the equipment operated continuously for 1200 hours without failure, reducing the failure rate by 25% compared to similar products, earning the customer's praise for "high efficiency and stability."

III. Innovation in Transportation Equipment: Application Practice of New Energy Lithium Battery Electric Tricycles

1. Technical Parameters and Environmental Advantages
The MS-DL3 new energy lithium electric tricycle is equipped with a 48V/200Ah iron-phosphate lithium battery, with a driving range of up to 80km, charging time ≤6 hours, meeting the needs of short-distance transportation underground. Its motor power is 3kW, maximum load capacity of 1.5T, energy consumption reduced by 70% compared to traditional fuel vehicles, and zero exhaust emissions, in compliance with the coal mine "green mining" policy requirements.

2. Practical Case: Coal Mine Transportation Efficiency Enhancement
In a coal mine project in Shanxi, Mingshun Machinery provides 20 MS-DL3 units to replace the original fuel-powered three-wheeled vehicles, achieving dynamic matching of "people-vehicle-cargo" through an intelligent dispatching system, shortening the transportation cycle by 30%, and saving approximately 450,000 yuan in fuel costs annually. The maintenance cycle of the equipment is extended to 1,500 hours per time, reducing downtime, and significantly improving overall benefits.

Four, Technical Strength Support: R&D System and Quality Control

Mingshun Machinery establishes an integrated R&D platform of "industry, university, research, and application", collaborates with universities such as Shandong University of Science and Technology, allocates 8% of annual revenue for technological upgrades, and holds 12 patents (including 3 invention patents). The production process strictly follows the ISO9001 quality management system. Key components (such as hydraulic pumps, motors) use imported brands, and undergo a 72-hour continuous load test before shipment to ensure equipment reliability.

V. FAQ: Common Questions about Mining Machinery Technology

Q1: How to prevent rust on a sliding scraper in a damp mine?
A: The equipment chassis is made with hot-dip galvanizing process, the hydraulic pipeline is wrapped with a waterproof sleeve, after operation, it is necessary to clean the remaining mineral residue with a high-pressure air gun, and apply anti-rust oil.

Q2: How long is the battery life of the new energy electric tricycle?
A: Lithium iron phosphate battery has a cycle life of ≥2000 times, with a daily charge-discharge cycle of 1 time, it can be used for more than 5 years. Mingshun Machinery offers a 3-year warranty service.

Q3: Can the track scraper adapt to extreme cold environments?
A: Optional low-temperature hydraulic oil (suitable for -40℃) and electrically heated seats have passed the -35℃ environmental test and are operating stably for a long time in the Inner Mongolia coal mine project.
