Key Structural & Performance Features

1. High Maneuverability & Reduced Operating Costs

• Compact Dual-Axle Geometry: Shorter overall length and reduced wheelbase design provide an exceptionally tight turning radius, allowing effortless maneuvering through narrow city streets, crowded job sites, and restricted plant access roads. PNG
• Optimized Tare Weight Efficiency: The lightweight 2-axle chassis architecture reduces dead vehicle weight, maximizing net payload capacity while significantly reducing fuel consumption during unladen return trips. PNG+ 1
• Lower Maintenance & Fleet Overhead: Featuring 8 tires and 2 axles instead of 3 or 4, fleet owners benefit from lower tire wear expenses, reduced brake maintenance, and reduced toll fees in axle-tariff transportation zones. PNG+ 1

2. Heavy-Duty Chassis & Hydraulic Lifting Power

• Front-Mounted HYVA Hydraulic Hoist: Equipped with a premium multi-stage HYVA telescopic cylinder mounted at the front of the box, maximizing mechanical leverage to ensure smooth, high-angle tipping (up to 55°) for rapid cargo clearance. PNG+ 2
• Submerged-Arc Welded High-Tensile Chassis: Constructed using Q345B/Q550 structural steel I-beams welded automatically via submerged-arc processes, delivering high frame rigidity and sag resistance under maximum payload loads. PNG+ 1
• Heavy Steel Decking & Automatic Tailgate: Built with a 6mm–8mm steel floor deck backed by transverse crossmembers. The top-hinged tailgate unlatches automatically via mechanical/pneumatic linkage during tipping and seals tight upon descent. PNG+ 1

3. Commercial Running Gear & Air Braking Safety

• 13T/16T Heavy Commercial Axles: Powered by 2 heavy-duty commercial axles (FUWA, BPW, STEYR, or AQ) rated for 13 to 16 tons capacity each, providing long service life and worldwide spare parts availability. PNG+ 1
• 11-Leaf Multi-Spring Suspension: Heavy-duty 11-piece leaf spring packs absorb shocks from unpaved construction site tracks and keep chassis load balance centered. PNG
• WABCO Air Braking System: Dual-line pneumatic compressed air braking system equipped with WABCO emergency relay valves and T30/30+T30 spring brake chambers ensures quick brake response and firm holding power during tipping operations. PNG
