Large Underground Mining Truck

When medium-sized mines face the transportation dilemma of "15-ton models can’t meet load demands, while 25-ton ones lack maneuverability," the 20-ton Large Underground Mining Truck launched by Shandong Beijun Machinery Industry Co., Ltd. has become the key solution with "optimally sized load capacity + full-scenario adaptability." Equipped with a Yuchai 160-horsepower power system and a reinforced load-bearing structure, this new model not only meets 20-ton heavy-duty requirements but also maintains flexible steering and passability. Verified in multiple medium-sized mining areas, its monthly transport volume has increased by 30% compared to 15-ton models, with an overall failure rate controlled below 2%.

Heavy-Duty Genes: All-Dimensional Enhancement from Power to Structure

The core competitiveness of the 20-ton mining dump truck lies in its ability to "carry heavy loads stably"—it must handle larger tonnages while maintaining reliability in complex road conditions:

Power Chain Adapted for Heavy Loads

It retains the proven combination of Yuchai 4108 intercooled turbocharged engine (160hp) and 10JS90 transmission, but with recalibrated fuel injection logic and gear ratios, increasing power output efficiency by 12% under 20-ton full load. In tests at an open-pit coal mine in Xinjiang, the truck maintained a higher average speed on 15° slopes than 15-ton models with the same power, being 5km/h faster and reducing one-way travel time by 18%.

Targeted Reinforcement of Load-Bearing Systems

Both front and rear axles adopt 153-type (10-hole) reinforced axles, paired with a 24# 8+8 riveted frame (torsional strength 15% higher than 15-ton models). In the "100-ton impact test" at a sandstone mine in Henan (simulating 100 consecutive 20-ton full-load trips), no deformation occurred in high-stress areas of the frame, with 100% weld integrity.

Efficient and Stable Hydraulic Lifting

The 130mm-diameter, 1200mm-stroke hydraulic cylinder features an optimized lifting pressure curve for 20-ton loads, completing full-load lifting in under 20 seconds. Even in -10℃ low temperatures, lifting operations remain smooth, solving the problem of slow lifting in northern mining areas during winter.

Durability Details: "Tough" Design for High-Wear Environments

Mining transportation’s "high-impact" scenarios demand extreme durability. The 20-ton model features refined "wear-resistant and damage-resistant" designs for key components:

Wear-Resistant Hopper Upgrade

The 4m×2.2m×0.8m hopper retains the "10mm bottom, 8mm side" thickened steel design but adopts "double-splicing welding + stress relief" technology. In tests at an iron mine in Shanxi, ore impact wear on the hopper was reduced by 25% compared to ordinary processes, extending service life to 9000 hours.

Tire and Suspension Adaptation

Standard 900-20 Kunlun mining steel wire tires (16-ply) include a "puncture-resistant steel wire layer," reducing puncture rates by 20% on gravel roads compared to 15-ton models. The front 12-piece and rear 10+8-piece 90mm×16mm leaf springs use "gradual stiffness" design (higher elasticity toward the ends), reducing vibration transmission on rough roads and lowering tire and frame wear rates by 10%.

Safety Redundancy in Braking Systems

All models come standard with wet braking, achieving a braking distance of ≤6.5 meters at an initial speed of 30km/h—0.8 meters shorter than the industry average for 20-ton models. Brake pads use "ceramic composite materials," improving high-temperature resistance by 30%, with brake fade controlled within 15% on continuous downhill sections (e.g., 2km slopes at a copper mine in Yunnan).

Scenario Adaptability: Left-Hand Drive + Flexible Configuration for Multiple Mining Needs

The 20-ton model’s "versatility" lies in its ability to meet domestic mining habits, quickly adapt to overseas markets, and balance passability across terrains:

Humanized Driving and Operation

Left-hand drive design, paired with a 1.4m×1.5m single-person semi-enclosed cab (with "layered thickened steel" on top, offering 10kN rock-fall impact resistance), aligns with domestic drivers’ habits and can be easily modified for left-hand drive markets in Southeast Asia and Africa. Hydraulic power steering reduces steering force to 35N, lowering driver fatigue by 40% after 8 hours of continuous operation.

Suitable for Both Narrow Lanes and Open Fields

With dimensions of 5.6m×2.3m×2m, it enables two-way traffic in 3.5m-wide roadways, improving passability by 25% compared to same-tonnage wide-body trucks. Its 2.3m width ensures hopper loading efficiency—carrying 5 tons more per trip than narrow 15-ton models in open-pit mines, reducing round trips.

Environmental and Compliance Adaptation

The water-based exhaust treatment device can be adjusted to meet local environmental standards. In tests at an ecologically sensitive mine in Inner Mongolia, emission indicators exceeded local requirements by 30%. It also holds national mining safety certification (KA mark), allowing access to all compliant mining areas without additional modifications.

Mine Test Feedback: "A 20-ton Truck with the Maneuverability of a 15-tonner and the Stability of a 30-tonner"

At an open-pit coal mine in Xinjiang, replacing two 15-ton trucks with one 20-ton model’s increased daily transport volume from 4500 tons to 6000 tons, reducing equipment count by 50% and lowering labor and maintenance costs by 25%. In a Southeast Asian gold mine (left-hand drive market), its quickly adaptable cab and compliant emissions enabled local certification in just 15 days, with 20 units delivered and put into use within a month.

A product manager at Beijun Machinery stated: "The 20-ton model is not simply an enlarged version of the 15-tonner, but a precise development for medium-sized mines to 'balance efficiency and flexibility'—allowing customers to invest in a 20-ton truck and gain the dual benefits of 'unfaltering heavy loads and fuel-efficient maneuverability.'"

Currently, the truck supports custom options such as plateau turbochargers (for altitudes above 4000m) and wear-resistant hopper liners (for high-hardness ores). For more specifications, visit Beijun Machinery’s official website.
