Intelligentization, unmanned operation and low-carbon green development have become the core trends of global smart mine construction. The 2nd Autonomous Mining Truck Engineering Application Conference 2026 focuses on large-scale operation of autonomous mining trucks, adaptation to extreme working conditions and full-chain construction of smart mines, aiming to promoting the intelligent upgrading and green transformation of the mining transportation industry. With two decades of deep industry expertise, Tonly Heavy Industries, a pioneer and leader in off-highway wide-body dump trucks, leads in the new energy autonomous mining truck with independent core technologies, full-scenario practical experience and green energy solutions. At the conference, the company launched its original unmanned drive-by-wire chassis and wind-solar-storage integrated mine microgrid system, providing a complete and mature solution for the large-scale implementation of smart green mines.

Benefiting from 20 years of technological accumulation and market cultivation, Tongli Heavy Industry has established absolute industrial and large-scale competitive advantages. At present, the global fleet of the company’s off-road wide-body trucks exceeds 70,000 units, ranking first in the industry in terms of market coverage and reputation. It takes the lead in the market share of new energy mining trucks, with one out of every two new energy mining trucks in service manufactured by Tonly Heavy Industries. In the field of intelligent unmanned technology, the self-developed proprietary drive-by-wire chassis boasts mature performance. More than 3,000 drive-by-wire chassis have been put into operation, with the maximum operating mileage of a single unit exceeding 300,000 kilometers, fully verifying its reliability under high-intensity mining operations. Up to now, over 6,000 intelligent new energy mining trucks of Tonly have been deployed, operating stably in more than 200 mines worldwide and enabling large-scale global application of unmanned intelligent equipment.

Extreme Condition Validation & Superior Reliability

The core value of mining equipment is proven under extreme working conditions. Every model in Tonly’s intelligent new energy mining truck portfolio has been validated across diverse and complex mining scenarios worldwide, capably handling harsh environments from high-altitude hypoxia and extreme cold to muddy heavy-load terrain and high heat and humidity. Proven field performance breaks through technical barriers, delivering intelligent mining transport equipment that is highly reliable, highly available, and highly adaptable.

High-altitude mines present complex conditions—low oxygen, steep grades, and extended downhill runs—that readily cause power loss and braking hazards in conventional diesel equipment. Tonly has refined its powertrain and braking systems accordingly, with its hybrid and pure-electric mining trucks fully conquering plateau operation challenges.

 At Tibet Yulong Copper Mine, at elevations exceeding 4,500 meters, and Tibet Julong Copper Mine—the world’s highest-altitude pure-electric wide-body truck operation—Tonly equipment maintains stable power output unaffected by oxygen-depleted conditions, handling demanding tasks such as ultra-long downhill runs and heavy-load uphill hauling with ease, setting the benchmark for electrified, intelligent plateau mining.

Battery capacity degradation, cold-start difficulty and sluggish system response in low-temperature environments have long been the core pain points restricting new-energy mining truck applications in cold regions. Through upgraded low-temperature-specific materials, an advanced intelligent battery thermal management system and customized charge-discharge strategies, Tonly has fully overcome the challenges of extreme-cold operation. 

Its hybrid new-energy equipment has been deployed at an extreme-cold copper mine in Kazakhstan, operating stably at temperatures as low as -35°C with normal starts, stops and full-cycle performance, filling the gap in large-scale new-energy equipment deployment at extreme-cold mines in Central Asia.

Muddy & Heavy-Load Adaptability: Optimized Chassis Durability

Complex heavy-load conditions such as muddy roads, continuous steep grades and material impact impose strict demands on chassis strength, mobility and power output. Tonly’s all-wheel-drive mining trucks draw on a high-strength impact-resistant body, optimized chassis architecture and a high-torque powertrain to adapt to diverse complex heavy-load scenarios. 

In a large-scale nickel mine project in Indonesia, the equipment handles rainy-season muddy roads, continuous 15%-20% grades and large-particle material impact with ease. With outstanding impact and deformation resistance, it serves as the primary haulage fleet in the mining area.

High-Temperature & Humid Adaptability: High Operational Availability

Desert environments with extreme heat, humidity and dust can readily cause cooling system failures and overload the battery, motor and power electronics—the key challenge for new-energy mining trucks. Tonly has accordingly optimized its cooling, air intake and dust-protection systems for extreme high-temperature scenarios.

 At a desert coal mine in Pakistan where temperatures reach 50°C, a fleet of more than 500 Tonly mining trucks operates continuously with a fleet availability rate of up to 96.9%. This highly stable, long-term field performance sets the benchmark for equipment operations at high-temperature mines worldwide.

Green Microgrid System for Sustainable Unmanned Mines

Building on its breakthrough in all-condition equipment adaptation, Tonly closes the energy gap for large-scale unmanned mine operations by establishing a diversified mine microgrid integrating solar, wind, diesel generation and energy storage. By creating a self-sufficient, low-carbon, efficient, safe and stable green energy closed loop, the company advances both equipment intelligence and green energy, completely removing end-to-end barriers to fleet-based, sustained, large-scale operation of autonomous mining trucks.

Two decades of dedicated craftsmanship, forging ahead with vision. Amid the wave of intelligent and green transformation in mining, Tonly will continue to build on proprietary drive-by-wire chassis technology, an integrated wind-solar-storage green microgrid system, and a full-lifecycle service platform. Staying true to its role as an industry pioneer and co-architect of standards, the company will keep leading the deep transformation of mining transport equipment toward intelligence, electrification, sustainability and unmanned operation, empowering the high-quality development of global smart mining.
