A 3T Tunnel Loader Backed by 20+ Years of Export Experience
As a professional loader manufacturer rooted in Shandong Taian, Taian Zhengtai Construction Machinery Co., Ltd. has shipped more than 12,000 units of construction machinery to over 80 countries in 20+ years of Chinese construction machinery export. This 3-ton tunnel loader is the direct result of that field data — a machine engineered for underground mining contractors who need one unit to cover mucking, hauling, and backfilling inside narrow galleries and hard-rock tunnels.
Every unit is assembled in our Feicheng Industrial Park factory with direct access to the most complete supply chain of heavy equipment components in China, allowing us to deliver factory price units without compromising on the 92 kW Luotuo 6108 diesel engine, 120 kN breakout force, or 9700 kg working weight that define this model.
Engineered for Complex Underground Working Conditions
Underground tunnels are rarely straight, dry, or generous with space. This 3-ton tunnel loader is validated against three of the harshest conditions our export customers face: narrow hard-rock galleries, wet muck piles with low visibility, and tight intersection turns. The 2440 mm overall width and 1800 mm wheelbase let the machine thread through galleries where standard surface loaders cannot enter, while the 380 mm minimum ground clearance keeps the chassis clear of uneven blasted rock.
The articulated steering system delivers a 40° maximum body steering angle with a 3750 mm inner passing radius — so the loader can pivot inside a blind intersection without multi-point turns. The 1.9 m³ bucket with 2440 mm width matches typical tunnel muck profiles, and the 2730 mm unloading height with 930 mm reach lets the bucket discharge cleanly into narrow mine cars or shuttle trucks without spilling material back onto the tunnel floor.
What Problems Does the 3T Tunnel Loader Solve for Your Business?
First, cycle time: a ≤12 second working device cycle (lift, dump, lower) combined with 10 km/h first-gear and 35 km/h second-gear travel speeds means more buckets per shift than comparable 3-ton underground loaders, directly reducing cost-per-ton mucked. Second, traction: the four-wheel drive with 70 kN maximum traction force and 25% grade ability holds grip on wet, sloping tunnel floors where two-wheel-drive machines slip.
Third, serviceability: a full stock of heavy equipment components — filters, seals, wet-brake parts, hydraulic hoses — plus Shandong Yunyu front and rear drive axles support long-term uptime without waiting on imported parts. Fourth, logistics: one unit fits into a standard shipping container with wire-rope fastening, and spare or wearing parts ship in fumigation-free wooden crates. Fifth, safety: the central wet brake and wet-type service brake hold the machine on grade even when fully loaded, reducing brake fade in humid tunnel environments.

Frequently Asked Questions
Are you a factory or a reseller?
We are direct manufacturers, experts in producing and exporting construction equipment such as underground loaders, wheel loaders, backhoe loaders, and bespoke machinery.
What is the minimum order quantity (MOQ) for the 3T tunnel loader?
Our MOQ is 1 unit for standard configurations. For custom bucket sizes, reinforced axles, or special tire packages, the MOQ is 2 units. As a direct loader manufacturer, we can combine mixed-container orders with other models to optimize freight cost.
How do you ensure quality before Chinese construction machinery export?
Every 3T tunnel loader undergoes a 45-minute full-load run-in test before crating. We verify hydraulic pressure, engine output, transmission shifting, wet-brake response, and electrical systems. Third-party inspection (SGS, BV, or Intertek) can be arranged at your request.
What is the warranty and after-sales support policy?
We offer a 12-month warranty or 2000 working hours (whichever comes first) on major components including engine, transmission, and hydraulic pump. Wearing parts (filters, seals, tires) are excluded. Our after-sales team responds within 24 hours via email or WhatsApp.
Can you provide the factory price and shipping cost to my port?
Yes. Please provide your destination port and quantity. We will quote FOB Qingdao or CIF within 12 hours. For standard containers, one unit fits per container with wire-rope fastening, and spare or wearing parts ship in fumigation-free wooden crates. We also offer DDP terms for select countries.
