Beijun 15-ton Wheeled Mining Dump Truck: A New Benchmark For Heavy Duty Scenarios Dual Upgrades In Power And Durability

In the field of heavy-duty transportation in small and medium-sized mines, the long-standing issues of "insufficient power for heavy loads and weak structure prone to wear" have restricted operational efficiency. Shandong Beijun Machinery Industry Co., Ltd.newly launched the 15-ton wheeled mining dump truck, which, with three core advantages of "high-horsepower engine + heavy-duty structure + precise adaptation", has become an ideal choice for medium-short distance heavy-duty scenarios such as sandstone mines, coal mines, and metal mines. Equipped with a Yuchai 160-horsepower engine, 10JS90 transmission, and reinforced hopper design, the truck increases single-trip transport volume by 25% compared to 12-ton models. It has completed field tests in multiple mining areas, with a stable daily attendance rate of over 95%.

Power and Transmission: 160HP "Heart" + Heavy-Duty Transmission, Ensuring Smooth Climbing and Loading

The core competitiveness of the 15-ton mining dump truck lies first in its "strong power and efficient transmission":

Super Power Output

Equipped with a Yuchai 4108 intercooled turbocharged engine (160HP), its torque is 18% higher than that of peer models. In a 20° steep slope test at a coal mine in Inner Mongolia, the full-load climbing speed remained at 8-10km/h, far exceeding the industry average of 5-6km/h, easily handling heavy-load climbing conditions.

Stable Transmission System

Matched with a 10JS90 transmission, its precise gear ratio design (10 forward gears + 2 reverse gears) enables efficient transportation at 15-20km/h on flat roads, while low-speed gears enhance torque in muddy roadways. The transmission efficiency reaches 92%, reducing power loss by 5% compared to ordinary transmissions.

Load-Bearing Axle Configuration

Both front and rear axles adopt 153-type (10-hole) reinforced axles, with a single axle rated load of 10 tons. Combined with a 24# 8+8 riveted frame (torsional strength increased by 30%), in a continuous 120-trip heavy-load transport test at a sandstone mine in Shanxi, the frame deformation was controlled within 0.5mm, with no weld cracks.

Durability Upgrade: 10mm-Thick Hopper + Steel Wire Tires, Further Enhancing Wear Resistance

Targeting the high-wear environment of mines, the 15-ton model features "toughness" enhancements in key components:

Wear-Resistant Hopper Design

The large 4m×2.2m×0.8m hopper uses 10mm-thick steel for the bottom and 8mm-thick steel for the sides. With a U-shaped arc structure, the ore residue rate is ＜1.5%, reducing cleaning time by 20% compared to ordinary hoppers. In quartz mine tests, the hopper’s service life reaches 8000 hours, 1.3 times that of ordinary models.

Mine-Specific Tires

Standard-equipped with 900-20 Kunlun mining steel wire tires (16PR), with a tread pattern depth of 18mm and a sidewall reinforcement layer thickness of 5mm. In gravel road tests, the puncture rate is 60% lower than that of ordinary tires, and the service life of a single tire is extended to over 6 months.

Leaf Springs and Hydraulic System

Front 12-piece and rear 10+8-piece 90mm×16mm thickened leaf springs, combined with a 130×1200mm large-bore hydraulic cylinder, enable lifting in just 18 seconds (under full load). Even in -15℃ low-temperature environments, the hydraulic oil remains fluid with no jamming.

Safety and Operation: Wet Brake + Left-Hand Drive Design, Adapting to Multiple Scenarios

The truck balances the particularities of mine operations and regional adaptability in safety and humanized design:

Brake Safety Assurance

Standard-equipped with a wet brake system, which achieves a braking distance ≤6 meters at an initial speed of 30km/h in dusty and waterlogged environments—1.2 meters shorter than dry brakes. It can remain stationary on a 20° slope for 30 minutes without rolling, and has passed national mining safety certification (KA mark).

Operational Convenience

The hydraulic power steering system reduces steering force to 35N, reducing driver fatigue by 40% after 8 hours of continuous operation. The shift cable design, combined with clear gear markings, allows new operators to master it quickly, reducing misoperation rates by 15%.

Regional Adaptation Details

Adopting a left-hand drive design, the cab features a 1.4m×1.5m single-person semi-enclosed structure with a thickened steel plate on the top (to prevent falling rocks). It not only meets the operational habits of most domestic mining areas but also can be easily modified to adapt to left-hand drive markets in Southeast Asia and Africa. The water-based exhaust treatment device complies with environmental requirements in multiple regions.

Mine Test Feedback: "One Trip Equals 1.2 Trips of the Old Model—Efficiency Has Really Improved"

At a coal mine in Inner Mongolia, after replacing the original 12-ton trucks 15-ton models, the daily transport volume increased from 3000 tons to 3800 tons, with transport trips reduced by 15% and fuel consumption lowered by 8%. At a copper mine in Jiangxi, its left-hand drive design and narrow body (2.3m wide) enable two-way traffic in 3m-wide roadways, improving traffic efficiency by 20% compared to peer wide-body trucks.

The R&D Department of Beijun Machinery’s Mining Equipment Division stated:"The 15-ton model is our precise layout for 'medium-short distance heavy-duty' scenarios—it fills the tonnage gap between 12-ton and 20-ton models, and through power and structural enhancements, makes it affordable and durable for small and medium-sized mines."

Currently, the truck supports personalized configuration based on mine altitude (optional plateau supercharger) and material characteristics (custom hopper material).
