FMY-2 Fuel Trucks

Product Overview

This 1,000–2,000 L mobile refueling vehicle is purpose-built for safe and efficient fuel transportation and refueling operations in underground mining environments. Incorporating advanced international technologies and independently designed and manufactured based on actual underground mining requirements, the vehicle features an integrated body structure mounted on a universal chassis with a fuel tank capacity of 1,000–2,000 liters. Its fully enclosed FOPS/ROPS-certified cab provides enhanced protection against falling objects and rollover hazards, while the four-wheel drive hydrostatic transmission system and DANA axles with wet multi-disc brakes deliver reliable traction and braking performance in demanding underground conditions. Combined with a coil-spring suspension system and low operating costs, this vehicle offers mining customers a safe, reliable and cost-effective solution for underground fuel distribution and on-site refueling.

Challenges Faced by Mining Customers

1. High safety risks in underground fuel transportationUnderground mining involves transporting flammable fuels through confined, narrow tunnels with falling rock and rollover hazards. Converted or standard fuel vehicles lack purpose-built protective structures and proper containment, exposing operators to serious risks of fire, explosion and fuel spillage in the event of an accident.

2. Poor traction and mobility on underground roadwaysUnderground mine roadways are often wet, muddy, steep and uneven. Two-wheel-drive or conventionally powered fuel vehicles struggle with traction, get stuck frequently, and cannot reliably navigate ramps and inclines, causing delays in fuel supply to working faces and increasing safety risks.

3. Insufficient braking reliability with heavy fuel loadsFuel vehicles operate at high gross weights, especially on steep underground ramps. Conventional dry-disc brakes are prone to overheating, contamination and reduced performance in wet, dusty underground environments, increasing the risk of brake failure and runaway incidents with catastrophic consequences.

4. Driver fatigue during long refueling routesUnderground refueling involves long travel distances over rough terrain to reach multiple working faces. Vehicles with inadequate suspension transmit excessive vibration and shock to the driver, causing fatigue, reduced alertness and increased risk of accidents during extended shifts.

5. High maintenance costs and frequent downtimeUnderground operating conditions accelerate wear and tear on fuel vehicles. Vehicles with non-standardized components and high failure rates require frequent repairs, consume excessive spare parts, and incur high maintenance costs and prolonged downtime, disrupting fuel supply schedules and mining production.

Solutions and Core Advantages

1. Advanced Technology and Purpose-Built Underground Refueling DesignThe vehicle incorporates advanced international technologies and is independently designed and manufactured based on the actual requirements of underground mining conditions. Purpose-built exclusively for underground fuel transportation and refueling operations, it features an integrated body structure and a universal chassis with a fuel tank capacity of 1,000–2,000 liters. This dedicated design ensures optimal weight distribution, stability and maneuverability for confined underground environments, unlike converted or generic fuel vehicles that compromise on safety and functionality.

2. FOPS/ROPS Certified High-Safety CabThe cab adopts a fully enclosed structure designed and tested in accordance with FOPS (Falling Object Protective Structure) and ROPS (Roll-Over Protective Structure) requirements. This certification provides enhanced protection for the driver against falling objects from the roof and rollover hazards on uneven underground roadways — critical when transporting flammable fuel loads. The fully enclosed design also isolates the operator from dust, noise and fuel vapors, creating a safer and more controlled working environment.

3. Four-Wheel Drive with Hydrostatic Transmission and Reliable Dual-Circuit BrakingThe vehicle features four-wheel drive (4WD) paired with a hydrostatic transmission system, delivering superior traction and torque control on wet, muddy, steep and uneven underground roadways — even when fully loaded with fuel. The braking system uses dual independent hydraulic brake circuits to enhance operational safety: if one circuit is compromised, the second remains fully functional. It is equipped with DANA axles (USA) featuring wet multi-disc brakes, which are sealed against contamination and provide consistent, fade-resistant braking performance under the most demanding underground mining conditions, including steep ramps and frequent stop-and-go operation with heavy fuel loads.

4. Superior Comfort with Coil-Spring Suspension and Hydraulic DampingThe chassis is equipped with a coil-spring suspension system combined with hydraulic damping cylinders, providing effective shock absorption and significantly reducing vibration transmitted to the cabin during operation over rough underground terrain. This dramatically improves driver comfort, reduces operator fatigue during long refueling routes, and contributes to higher alertness and safety. The smooth ride also protects the driver from chronic vibration-related health issues associated with prolonged operation of heavy mining vehicles.

5. Stable Quality, Low Failure Rate and Low Spare Parts ConsumptionThe vehicle is engineered for stable and reliable operation under demanding underground mining conditions, with a low failure rate and low spare parts consumption. The use of proven, standardized components — including DANA axles and established hydrostatic transmission technology — ensures predictable maintenance intervals and readily available replacement parts. This helps mining customers reduce overall operating and maintenance costs, minimize unplanned downtime, and maintain consistent fuel supply schedules that support uninterrupted mining production.
