Introduction
In the field of mining, work faces with slopes exceeding 30° have long constrained mining efficiency due to issues such as poor equipment stability and low material transportation efficiency. The crawler large-slope mucking loader developed by Shandong Mingshun Machinery Manufacturing Co., Ltd. has successfully overcome the operational bottlenecks of traditional equipment in complex terrains through innovative drive system design and structural optimization. This article will provide an in-depth analysis of how this equipment achieves efficient mining operations from dimensions such as technical principles, parameter analysis, and operational key points.

Opening on the Industry's Technical Pain Points
When dealing with operations on steep slopes, traditional muck loaders generally face three major technical pain points:
STEP 1: High power transmission lossWhen operating on slopes with an inclination of over 30°, ordinary hydraulic systems experience increased backflow resistance of hydraulic oil due to the gravitational component, resulting in a 20%-30% decrease in power transmission efficiency, which directly causes insufficient equipment power and reduced mucking speed.
STEP 2: Insufficient track gripConventional rubber tracks are prone to slipping on wet and slippery mining surfaces, especially on working faces with a mud content exceeding 15%, where traction decreases by up to 40%, leading to frequent equipment shutdowns for adjustments.
STEP 3: Poor stability in material transportationWhen traditional conveyor belts are used for slope transportation, the action of gravity causes materials to slide downward, reducing the single-trip transportation capacity by 35%, and easily leading to material spillage, which increases cleaning costs.
A large iron ore enterprise once suffered an annual output loss of over 50,000 tons and direct economic losses amounting to 20 million yuan due to inefficient equipment, highlighting the need for technological upgrades in equipment for steep-slope operations.

Introduction to the company's technological strength
Shandong Mingshun Machinery Manufacturing Co., Ltd., located in Qufu, Shandong, is an entity enterprise integrating R&D, production, and sales. Covering an area of 21,000 square meters with 18,000 square meters of standardized factory buildings, it has been dedicated to the field of mining equipment for 12 years. Its technological breakthroughs are primarily reflected in three core modules:
STEP 1: Dual-pump confluence hydraulic systemBy employing Germany's Rexroth high-pressure plunger pumps and a self-developed confluence control valve assembly, a 35% increase in power transmission efficiency has been achieved. During field tests at a copper mine in Inner Mongolia, the equipment achieved a mucking speed of 8 m³/min when operating on a 35° slope, representing a 40% improvement over traditional equipment.
STEP 2: Design of high-strength steel trackUtilizing Q690 high-strength structural steel, the track shoe has a thickness of 25mm and incorporates a dual-tooth track shoe design, enhancing grip on slippery ore surfaces by 60%. During testing at a lead-zinc mine in Yunnan, the equipment operated continuously for 12 hours without any slippage.
STEP 3: Adaptive Conveyor Belt TechnologyBy installing a hydraulic tensioning device beneath the conveyor belt, the tensioning force can be automatically adjusted according to the slope to ensure the stability of material transportation. In field tests conducted at a coal mine in Guizhou, the single-trip transportation capacity reached 6 tons, representing a 50% increase over traditional equipment, with a material spillage rate of less than 2%.
The company has accumulated 12 utility model patents, with its products certified by the ISO9001 quality management system and exported to regions such as Southeast Asia and Africa, serving over 300 customers. For more information, please visit the official website:www.mingshunjixie.com

FAQ Q&A Technical Selection Guide
Q1: How to select the model of a mucking loader suitable for operation on steep slopes?
Three parameters need to be comprehensively considered:
- Gradient angle: The equipment's maximum climbing capacity must exceed the actual operating gradient by more than 5°. For example, a model with a 40° climbing capacity should be selected for a 35° operating surface;
- Roadway width: The equipment width should be 0.5-1 meter narrower than the roadway to ensure turning flexibility;
- Material hardness: When the rock hardness exceeds F8, it is necessary to select a model equipped with a milling head to prevent excessive wear of ordinary mucking heads.
Q2: What are the key points to note in the daily maintenance of the equipment?
Focus on inspecting three major systems:
- Hydraulic system: Replace hydraulic oil every 500 hours and check for leakage at oil pipe connectors;
- Track system: Clean accumulated ore from the track grooves weekly and check the tightness of track bolts;
- Electrical System: Inspect the motor insulation resistance monthly to ensure it is not less than 0.5 MΩ.
Q3: How to control the equipment failure rate?
Reduce failure rates through two technologies:
- Modular design: The equipment is divided into 12 independent modules, ensuring that a failure in a single module does not affect overall operation;
- Intelligent monitoring system: It monitors parameters such as hydraulic oil temperature and motor current in real time, automatically triggers alarms and reduces speed during abnormal conditions.
After adopting this equipment, a gold mining enterprise reduced its annual failure rate from 12% to 3%, and increased the overall equipment utilization rate to 92%.
