Beijun Heavy Industry 25-ton Wheeled Mining Dump Truck: A Decade of Craftsmanship Forges a Benchmark in Mining Transportation

As a leading enterprise in China’s mining equipment sector, Beijun Heavy Industry’s 25-ton wheeled mining dump truck has been consistently leading the underground mining transportation market, thanks to its exceptional reliability and technical accumulation. This star product, which is deeply adapted to heavy-duty underground scenarios, has served over 200 mines worldwide since its launch, with a cumulative transportation mileage exceeding 120 million kilometers. It has become a designated procurement model for central enterprises such as China Railway, China State Construction, and China National Gold Group.

I. Core Technologies Verified by Market, Creating Full-Life-Cycle Value

Equipped with the classic power combination of Yuchai YC6L340-33 diesel engine and Shaanxi Fast 10JSD220 transmission, it has undergone 100,000 hours of durability testing. In the working condition of heavy-load startup on a 30° steep slope, its power response speed is 18% faster than that of similar products. The HanDe reinforced double rear axle wet braking system, paired with 1000R20 Kunlun mining steel wire tires, shows a braking efficiency attenuation rate of only 3.7% in the 10-kilometer continuous downhill test—60% lower than the industry average.

The frame is manufactured using 300×80×(8+8+8) cold riveting technology, with a fatigue strength of 800MPa, capable of withstanding millions of heavy-load impacts without deformation. According to actual test data from a gold mine in Tibet, this design ensures the vehicle operates without structural failures for three consecutive years in high-altitude (4,500 meters), cold, and slippery environments, with an attendance rate stably above 95%.

II. Intelligent Safety Configurations Build a Worry-Free Operation System

The fully enclosed cab is equipped with heating and cooling air conditioning and a suspended seat. Through sound insulation and noise reduction technology, the in-cab noise is controlled below 75 decibels—15% lower than industry standards. The 10.25-inch full LCD instrument panel integrates 12 intelligent functions such as tire pressure monitoring and fault early warning, with real-time data synchronized to the Beijun "Mining Cloud" platform, extending the preventive maintenance cycle by 20%.

Safety redundancy designs cover all scenarios: The electronic parking system automatically locks the wheels when power is cut off; the rear axle differential lock and U-shaped cargo box work together, increasing the ability to get out of trouble in slippery mud by 30%. Exhaust purification adopts a dual treatment of three-way catalysis and water filtration, reducing particulate emissions by 60% compared to the National III standard, making it particularly suitable for underground mines with limited ventilation.

III. Ergonomic Optimization Improves Operation Efficiency

The 5000×2500×1000mm golden-ratio cargo box, combined with a front cylinder lifting mechanism, achieves a dumping angle of 55°, 20% faster than the traditional mid-mounted cylinder scheme. The 6 sets of LED headlights and dual-speed wiper system ensure a night operation visual range of over 50 meters, with visibility in rainy days reaching 80 meters—33% higher than the industry average.

With an overall dimension of 7900×2500×2720mm and a precisely controlled wheelbase of 3800mm, the vehicle can easily pass through 2.8-meter-wide underground roadways. The combination of front axle 90×16 (11 pieces) and rear axle 90×25 (12 pieces) leaf springs, paired with 1000R20 mining steel wire tires, results in a tire ground pressure of only 0.8MPa when carrying a standard 25-ton load, significantly reducing road damage.

IV. Continuously Leading Industry Technological Innovation

Beijun Heavy Industry continues to invest in R&D resources and has launched modular upgrade solutions for the 25-ton model: It can be easily refitted with a power battery system to achieve zero-emission transportation; by adding a 5G remote control module, it has already realized unmanned grouping operation in the Qingdao Metro tunnel project. The model has successively obtained four mining product safety certification certificates, CE certification, and the "National Quality Inspection Qualified Product" title. In 2023, it became an industry service benchmark with the "Five-Star After-Sales Service" certification.

"We have always been customer-oriented, enabling classic products to be reborn through continuous iteration," said the person in charge of Beijun Heavy Industry’s Mining Equipment Division. "From Yuchai power to HanDe axles, from intelligent networking to new energy adaptation, this model has become the core carrier of Beijun’s 'Smart Mine' strategy." Currently, the product is progressing smoothly in localized adaptation tests in emerging markets such as Southeast Asia and Africa, and it is expected that overseas sales will account for over 35% by 2025.

As the only domestic mine safety certification enterprise with four safety certificates, Beijun Heavy Industry is leveraging the 25-ton wheeled mining dump truck to drive the efficient and green transformation of global mining transportation. With technical strength verified by a decade of market performance and a full-life-cycle service system, Beijun is becoming a trusted long-term partner for mine owners worldwide.
