• Gross Vehicle Weight (GVW): 35,000 kg
• Wheelbase: 3,900 + 1,370 mm
• Engine: Isuzu 6WG1-TCG60, 420 hp, inline six-cylinder turbocharged
• Transmission: Fast 12-speed manual transmission (12 forward gears + 2 reverse gears)
• Tires: Front 385/65R22.5, Rear 315/80R22.5
• Axle: Front 7.5 tons, Rear 13 tons x 2 dual rear axles

▶ Upper Structure:
• Internal Dimensions: 5,600 × 2,300 × 1,200 mm
• Plate Thickness: Side Plates 6 mm, Bottom Plate 8 mm
• Material: High-strength carbon steel (Q345B)

• Structural Design:
♢ Type: Front-lift self-unloading type
♢ Side Plates: Grid-like reinforcing ribs (horizontal and vertical ribs welded into a grid pattern to prevent deformation of the box under loading impact)
♢ Welding Process: Full welding (all seams are continuously welded to ensure sealing and structural strength)
♢ Rear Door: Automatic release hook device (the bottom hook of the rear door automatically opens during lifting to avoid linkage accidents)

• Control Method: Pneumatic Body Lowering Control
Principle: The lowering circuit of the lifting hydraulic system is controlled by a pneumatic valve in the cab, achieving a smooth and slow descent of the cargo box to prevent damage to the chassis from heavy-load descent impacts.
• Load Capacity
♢ Recommended Cargo Box Load Capacity: 25-30 tons
♢ Applicable Materials: Transportation of ore, coal, mineral powder, sand, gravel, construction waste, and excavated soil.
