Opening with the Pain Points of Industry Technology
Traditional ore loading equipment often faces three major challenges in mining operations:
STEP 1: Poor adaptability to complex terrainsMine roadways feature steep slopes and narrow spaces, making ordinary mucking loaders prone to issues such as slipping and overturning, resulting in an operational interruption rate as high as 30%.
STEP 2: Prominent contradiction between power and energy consumptionAlthough high-power equipment can enhance efficiency, its energy consumption costs account for over 40% of total operating costs, and its emission issues struggle to meet environmental protection requirements.
STEP 3: Short maintenance cycle and high costMine dust and humid environments accelerate equipment wear, with key components having a lifespan of less than 2,000 hours and annual maintenance costs exceeding 200,000 yuan.
Taking a medium-sized iron ore mine as an example, its traditional mucking machines, due to slope adaptability issues, accumulate up to 72 hours of monthly downtime for maintenance, resulting in direct losses exceeding 500,000 yuan. Such pain points urgently require technological upgrades to resolve.

Introduction to the company's technological strength
Shandong Mingshun Machinery Manufacturing Co., Ltd., located in Qufu, Shandong, covers an area of 21,000 square meters and possesses standardized workshops spanning 18,000 square meters. It is an entity enterprise integrating research and development, production, and sales. The company focuses on two major fields: ore loading equipment and transportation equipment, with core products including sliding mucking loaders, crawler large-slope mucking loaders, milling excavators, and 1.5T-20T trolley locomotives.
Technical layout and advantages
STEP 1: Terrain Adaptation TechnologyBy optimizing the track structure and hydraulic system, stable operation on slopes with a maximum gradient of 35° is achieved. For instance, its track-type mucking loader for steep slopes employs high-strength alloy track shoes, each with a bearing capacity of up to 5 tons, and is equipped with an independent hydraulic tensioning device that automatically adjusts track tension to adapt to different geological conditions.
STEP 2: Balanced Design of Power and Energy ConservationIt is equipped with a diesel engine compliant with China's National III emission standards, with a power range of 55-132kW. Coupled with an intelligent speed regulation system, it can dynamically adjust rotational speed based on load, reducing overall fuel consumption by 15%. Taking the SL-80 sliding mucking loader as an example, its hourly fuel consumption is only 12L, saving 2L compared to similar products.
STEP 3: Modular Maintenance SystemKey components such as hydraulic pumps and motors feature a quick disassembly and assembly design, reducing maintenance time by 60%. For instance, its patented hydraulic oil circuit manifold block compresses the traditional 8-hour maintenance process to just 3 hours, lowering the average annual maintenance cost to 80,000 yuan.
Actual Case: A Copper Mine Project in Yunnan
In 2023, a copper mine in Yunnan introduced Mingshun Machinery's SL-120 crawler-type large-slope mucking loader. The average gradient of the mine's roadways is 28°, with traditional equipment achieving a daily average operation volume of only 120 tons and requiring frequent shutdowns for adjustments. By utilizing terrain adaptive technology, Mingshun's equipment increased the daily average operation volume to 220 tons, reduced the failure rate from three times per month to 0.5 times, improved overall efficiency by 83%, and shortened the project duration by 40%.

FAQ: A Q&A Guide to Technical Selection
Q1: How to select the model of mucking loader based on mine conditions?
A: It is necessary to comprehensively evaluate the roadway gradient, width, and material characteristics.
STEP 1: Slope ≤ 20°Priority should be given to selecting a sliding muck removal machine, which has a body width of 1.2-1.5 meters and a small turning radius, making it suitable for narrow spaces.
STEP2: Slope 20°-35°A crawler-type, large-gradient mucking loader should be selected, with a ground contact pressure of the crawler ≤ 0.08 MPa to prevent slipping.
STEP 3: Material hardness > F6It is recommended to configure a milling excavator to assist in rock breaking, with its milling head rotating at a speed of up to 120 rpm, increasing the breaking efficiency by 50%.
Q2: How should equipment operating parameters be set to optimize efficiency?
A: Taking the SL-80 sliding muck loader as an example:
STEP 1: Engine SpeedSet to 1500 rpm under light load and increased to 1800 rpm under heavy load to avoid stalling caused by low speed and high load.
STEP2: Hydraulic System PressureThe standard operating pressure is 16 MPa, which can be temporarily increased to 20 MPa during rock breaking, but the duration of each increase shall not exceed 3 minutes.
STEP3: Track TensionUse a tensiometer for detection. The sag of the track should be controlled within 30-50mm. Excessive tightness increases energy consumption, while excessive looseness makes it prone to derailment.
Q3: Which components require key attention during routine maintenance?
A：
STEP 1: Cleanliness of hydraulic oilReplace the filter element every 500 hours, and ensure the oil cleanliness reaches NAS Grade 8 to prevent wear of the pump and valve.
STEP 2: Wear of track shoesCheck the thickness of the track shoes monthly, and replace them when the remaining thickness is less than 50% of the original size to avoid the risk of fracture.
STEP 3: Electrical System InsulationInspect the motor's insulation resistance every quarter, with the resistance value required to be ≥1MΩ to prevent electric leakage accidents.
