• Wet Brake System: Superior safety performance in dusty and humid tunnel environments

• Low Profile Design: 2550mm overall height fits standard 2.8m+ tunnel heights

• Four-Wheel Drive: 70kN maximum traction force for steep underground ramps

• Shandong Yunyu Axles: Heavy-duty axles proven in thousands of mining applications

Taian Shandong: China's Underground Construction Machinery Hub

As a leading wheel loader manufacturer and specialized underground equipment producer based in Taian, Shandong – China's most comprehensive construction machinery industrial cluster, Zhengtai Machinery benefits from a 30-year-developed supply chain ecosystem tailored for mining and tunneling equipment. 

📦 Packaging & Shipping: Secure Global Delivery

For secure international delivery, the 3T Tunnel Loader main body is unpacked but firmly secured inside the container with heavy-duty wire ropes and steel brackets to prevent movement during transit. All spare parts and wearing components are individually wrapped and protected in fumigation-free wooden boxes or reinforced paper cartons.

20+ Years of Mining Equipment Export Excellence

With over two decades of specialized experience in Chinese construction machinery export, Zhengtai Machinery has developed unparalleled expertise in serving the unique needs of global mining and tunneling markets. We have successfully exported our underground loaders to over 40 countries across Africa, Southeast Asia, South America and the Middle East, where our equipment has proven its reliability in the most challenging mining conditions. 

Engineered for the Demands of Underground Environments

The 3-ton underground tunnel loader is specifically designed to address the unique challenges of mining and tunneling operations. Its low 2550mm overall height allows it to operate in tunnels as low as 2.8 meters, while the 380mm minimum ground clearance provides excellent obstacle clearance over uneven tunnel floors and rocky terrain. The fully enclosed wet brake system delivers superior stopping power and reliability in dusty, humid and muddy underground conditions, eliminating the brake fade issues common with dry brake systems. The 92kW Luotuo 6108 engine provides ample power for climbing steep ramps and loading heavy materials, while the four-wheel drive system ensures maximum traction on slippery surfaces. The reinforced steel chassis and boom structure are built to withstand the constant shocks and vibrations of underground mining operations.

Company Profile

Solving the Unique Challenges of Small and Medium Mining Operations

The 3-ton underground tunnel loader was specifically developed to address the most pressing pain points faced by small and medium mining companies and tunneling contractors. Unlike large international brands that require significant upfront investment and have high maintenance costs, our loader offers exceptional value with a factory price that is 50-60% lower than comparable imported equipment. The Luotuo 6108 engine and Shandong Yunyu axles are widely used in construction machinery worldwide, ensuring that heavy equipment components are readily available and affordable. 

Comprehensive Customer Support and Fast Parts Delivery

As a customer-focused wheel loader manufacturer, we understand that equipment downtime directly impacts your mining operations and profitability. While we do not maintain overseas parts warehouses, we have established efficient international shipping partnerships that allow us to deliver genuine heavy equipment components to most global destinations within 7-14 days via express courier, or 25-35 days via sea freight.
