2026 sees Beijun expand its underground dump truck lineup, tighten cold-weather performance, and strengthen service networks across Central Asia, Africa, and South America.

The global underground mining truck market keeps expanding. Rising demand for copper, gold, and lithium continues to push mines deeper and further into remote regions. For mine operators, the challenge is not just hauling ore. It is finding trucks that fit narrow tunnels, survive extreme temperatures, and stay running when parts are thousands of kilometers away.

Beijun Group has been building underground mining trucks for over a decade. In 2026, the company is making moves to serve those markets better. Here is what is happening.

Central Asia and Mongolia: Built for 2.4-Meter Tunnels and -40°C Winters

One of the biggest pain points for mines in Central Asia and Mongolia has nothing to do with ore grade. It is tunnel width. Many local operations have roadways limited to 2.4 to 2.8 meters in width. Add winter temperatures that drop to -40°C, and standard haulage equipment simply does not work.

Beijun addressed this with slim-chassis designs and cold-resistant upgrades. The trucks now feature reinforced structures that handle extreme cold without cracking. In an 8-month continuous field test at a Mongolian mine, Beijun trucks recorded zero wall collisions or jamming accidents. Turning radius was reduced by 18% through an optimized steering system.

A Ghanaian mine owner learned this lesson the hard way in 2025. He spent $750,000 on three new mining dump trucks, shipped them 4,000 miles, and discovered they could not fit in his underground tunnels. Too tall. Too wide. "Even after modifications, they were useless," he later said. That story is a reminder: underground mining trucks must be specified for the tunnel, not the other way around.

Global Service Network Grows Alongside Product Line

Beijun's underground mining trucks now serve mines in more than 20 countries. The company has overseas branches in Chile, Peru, and Kazakhstan. Domestic service includes 8 regional centers and 26 parts warehouses. The company offers a "4H rapid response" mechanism and parts delivery within 72 hours for overseas operations.

That network matters. In mining, downtime costs money. A truck waiting for a brake caliper is a truck not moving ore. Beijun's approach is to keep critical spares close to where they are needed.

2026 Award Recognizes Underground Equipment Focus

In April 2026, Beijun Group's subsidiary Shandong Ante Heavy Industry received the "2026 Efficient Intelligent Mining Equipment Leader" award at the China Iron Ore Full Industry Chain Conference in Xichang, Sichuan.

The recognition reflects Beijun's work in underground trackless equipment. The company's UQ-45 underground dump truck was recognized as a Shandong Province "First Set" technical equipment, filling a domestic gap. The R&D team holds 34 patents and has obtained mine safety certificates for UQ-5 through UQ-45 models, along with ISO9001, ISO14000, and EU CE certifications.

Product Range: From 3.5 Tons to 45 Tons

Beijun's underground mining truck lineup covers 3.5 tons to 45 tons. That range serves small narrow-vein operations and large production mines alike.

The UQ-35 is one of the workhorses. It carries 35 tons, uses a Yuchai engine paired with a Fast gearbox, and features a cold-riveted frame made from 300x80x(8+8+8) steel. The wet brake system is fully enclosed and oil-cooled, designed for long downhill hauls under heavy loads.

For smaller tunnels, the UQ-12 offers a 12-ton payload with a compact 5000×2000×1700mm footprint. It uses a Yuchai 4102 turbocharged engine and features water-filter exhaust purification to reduce underground air pollution.

What This Means for Buyers

For mine operators evaluating underground haulage options, a few things stand out from Beijun's 2026 direction.

Tunnel fit matters more than price. The Ghanaian case is a costly example. Measure your narrowest drift, your lowest roof, your tightest turn. Then buy the truck that fits.

Cold and heat both test equipment. Central Asia and Mongolia demand cold-resistant steel and hydraulics. Tropical operations need cooling and corrosion protection. Beijun builds both.

Parts availability is a strategic decision. A truck is only as good as its support network. Beijun's 72-hour parts commitment for overseas operations is a concrete benchmark to compare against other suppliers.

The full lineup matters. From 3.5-ton narrow-vein trucks to 45-ton production haulers, Beijun covers the underground haulage spectrum. That standardization means common parts and familiar maintenance procedures across a fleet.

For mines looking for underground mining trucks that fit narrow tunnels, handle extreme conditions, and come with an expanding global service network, Beijun is worth a closer look.
