IV. Structural & Component Advantages
Engine – Q28 Quanchai 156HP
Delivers low-speed high torque (450Nm) for strong starting acceleration and climbing power. This "low-speed, high-torque" characteristic ensures responsive performance in stop-and-go urban conditions and on inclined ramps during vehicle loading. Meets stringent China VI emission standards for environmental compliance.
Transmission – WLY 6-Speed
Provides smooth, reliable gear shifting with optimized gear ratios that complement the engine's torque curve, enhancing fuel efficiency and drivability across diverse road conditions.
Front & Rear Axles
The 2.7-ton front axle combined with the 5.5-ton rear axle delivers superior load-carrying capacity and enhanced climbing capability. This robust axle configuration ensures stability and durability when transporting heavy passenger vehicles.
Frame – Double-Layer Straight-Through Beam
The heavy-duty double-layer frame structure significantly enhances torsional rigidity and bending resistance, providing a stable foundation for the vehicle carrier body and ensuring long-term durability under high-load operations.
Power Take-Off (PTO)
Factory-installed PTO enables one-touch control of the hydraulic system, simplifying operation and improving workflow efficiency.
