Introduction
In mining and tunnel construction, steep-slope working environments impose stringent demands on equipment performance. Due to issues such as inadequate climbing capacity and poor stability, traditional muck loaders often result in low operational efficiency and even safety accidents. Leveraging years of technical expertise, Shandong Mingshun Machinery Manufacturing Co., Ltd. has introduced a crawler-type steep-slope muck loader. By optimizing the power system and chassis structure, it achieves stable operation on slopes of up to 35°, setting a benchmark for technological breakthroughs in the industry. This article will analyze the technical principles, corporate capabilities, and selection guidelines to provide mining enterprises with references for equipment upgrades.

Opening on the Pain Points of Industry Technology
In mining operations, scenarios involving steep slopes account for over 40%, yet traditional equipment faces three major technical bottlenecks:
STEP 1: Insufficient PowerThe common slag-raking machine uses a single-cylinder diesel engine with a power of only 55 kW. When facing slopes steeper than 30°, its traction force decreases by 30%, leading to interrupted climbing or slipping.
STEP 2: Poor chassis stabilityWheeled structures are prone to rollover on slippery slopes, while tracked equipment, if not optimized for ground pressure distribution, can result in a subsidence rate as high as 25%, affecting operational continuity.
STEP 3: Low operational flexibilityThe traditional hydraulic system has a response delay of up to 0.8 seconds, and when turning in narrow alleys, the tail swing amplitude of the equipment exceeds 1.2 meters, increasing the risk of collision.
A large iron ore mine once experienced a 40% drop in daily output and direct economic losses exceeding 200,000 yuan due to insufficient equipment climbing capacity, highlighting the urgency of technological upgrades.

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 R&D, production, and sales. The company focuses on the field of mining equipment and has developed two major technological advantages:
STEP 1: Power System InnovationThe self-developed combination of a "twin-cylinder turbocharged diesel engine + hydraulic torque converter" has increased its power to 88 kW and its maximum tractive force to 120 kN. Field tests demonstrate that it can operate continuously for 8 hours without failure on a 35° slope.
STEP 2: Chassis Structure OptimizationIt employs high-strength manganese steel tracks with a width extended to 450mm, reducing ground pressure to 0.08MPa. Coupled with a four-wheel independent suspension system, the sinkage rate is controlled within 5%. In 2023, this technology was granted a national utility model patent (Patent No.: ZL20232XXXXXXX.X).
In a coal mine project in Inner Mongolia, Mingshun Machinery's crawler large-slope mucking loader achieved a single-day loading capacity exceeding 1,200 tons, marking a 60% increase in efficiency compared to traditional equipment, while reducing equipment failure rates to 0.3 times per month.

FAQ Q&A Technical Selection Guide
Q1: How to select the appropriate model of slag-raking machine?
A: Three parameters need to be considered comprehensively:
- Slope angleIf the gradient of the working face is ≥30°, prioritize the selection of Mingshun Machinery's PLB-35 model (with a maximum climbing gradient of 35°);
- Roadway widthFor narrow roadways (≤3m), it is recommended to select the PLB-25 model, which has a body width of only 2.2 meters;
- Loading capacityFor a daily processing capacity below 500 tons, choose a 1.5 m³ bucket; for over 1000 tons, a 3 m³ high-capacity model is required.
Q2: What are the key points of equipment maintenance?
A: Focus on inspecting three indicators:
- Hydraulic oil temperatureNormal operating range: 60-80℃. Shutdown for maintenance is required if the temperature exceeds 90℃.
- Track tensionMeasure with a special tool; the looseness should be controlled within 15-20 mm.
- Engine speedIt should stabilize at 1500-1800 rpm under no-load conditions, and adjustments to the fuel injection pump are required if fluctuations exceed ±5%.
A copper mine failed to regularly inspect the hydraulic oil temperature, resulting in oil seal aging and leakage, and increasing maintenance costs by 30,000 yuan, highlighting the importance of standardized maintenance.
