Introduction to Industry Technical Pain Points
In current mining and tunnel construction, large-slope operation scenarios impose stringent requirements on the stability, power output, and adaptability of mucking loaders. When traditional equipment operates on ramps with slopes exceeding 30°, issues such as track slippage, insufficient power, and low mucking efficiency frequently arise, leading to an operation interruption rate as high as 30%. Additionally, problems like high equipment maintenance costs and poor universality of spare parts further constrain construction efficiency. Shandong Mingshun Machinery has addressed these pain points through technological innovation, with its developed tracked mucking loader for large slopes demonstrating significant improvements in comprehensive performance under complex terrain conditions.

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 boasts 18,000 square meters of modern workshops and warehouses. It is an entity enterprise integrating R&D, production, and sales. The company focuses on the field of ore loading equipment, and its crawler large-slope mucking loader employs the following core technologies:
STEP 1: Powertrain System Optimization
Equipped with a customized diesel engine with a rated power of 110 kW and a maximum torque of 650 N·m, combined with a hydraulic torque converter, it achieves linear adjustment of power output, ensuring a loading efficiency of over 85% even on 45° slopes.
STEP 2: Innovation in Track Structure
High-strength alloy steel track shoes with a width of up to 800 mm are adopted, reducing ground pressure to 0.12 MPa. When combined with an independent suspension system, they effectively distribute the equipment's weight and reduce the risk of slippage. Measured data shows a 40% improvement in equipment stability on wet 35° slopes.
STEP 3: Intelligent Control System
It integrates a gradient sensor with a hydraulic flow control module to automatically adjust the angle and hydraulic pressure of the loading arm, ensuring operational precision. For example, in tunnel excavation, the system can monitor gradient changes in real time, dynamically optimize the loading path, and reduce manual intervention.
The company's technical team boasts over 10 years of industry experience, has accumulated 12 utility model patents, and its products have passed ISO9001 quality management system certification. The team has served more than 30 large-scale mining projects domestically, with the equipment achieving an average Mean Time Between Failures (MTBF) of 1,200 hours.

FAQ: A Guide to Q&A-Style Technical Selection
Q1: How to select the model of a mucking loader suitable for operations on steep slopes?
Model selection requires a comprehensive consideration of three parameters:
- GradeabilityPriority should be given to models with a nominal gradeability of ≥45°, such as the LPD-45 model from Mingshun Machinery, which has a measured gradeability of up to 48°;
- Loading capacitySelection is based on the dimensions of the roadway cross-section; for example, a 1.2 m³ capacity model is recommended for a 2m×2m cross-section.
- Power matchingTo ensure that the engine power matches the hydraulic system flow rate, Mingshun Machinery adopts the "power-flow" dual calibration technology to avoid power waste.
Q2: What faults are prone to occur in equipment under extreme operating conditions? How can they be resolved?
Common faults and solutions:
- Track derailmentThe causes are mostly insufficient track tension or foreign objects on the ground getting stuck. Mingshun Machinery has reduced the failure rate by 60% by installing an automatic tensioning device to monitor track tension in real time;
- Overheating of hydraulic systemThis is often caused by prolonged high-load operation. The company employs a dual-circuit cooling system to keep the hydraulic oil temperature below 65°C, thereby extending the lifespan of components;
- Shoveling arm jitterIt is usually caused by internal leakage in hydraulic cylinders. Mingshun Machinery selects imported seals and conducts regular pressure tests to ensure the stability of the hydraulic system.
Q3: How to evaluate the comprehensive cost-effectiveness of equipment?
It is recommended to make comparisons from three aspects:
- Initial costThe price of Mingshun Machinery's LPD-45 model is approximately 850,000 yuan, which is 25% lower than that of imported brands;
- Maintenance costThe spare parts have high universality, and the cost of single maintenance is 15% lower than the industry average;
- production efficiencyField tests show that Mingshun's equipment can achieve a daily excavation and loading volume of 320 m³ on a 30° slope, representing a 20% increase compared to traditional equipment.
