Product Introduction
I. Core Structure & Working Principle
Unloading Mechanism:
Hydraulic cylinders tilt the cargo box backward (typically ≥45° inclination) around the rear axle, allowing materials to slide out by gravity. Key components include lifting cylinders, piston rods, tipping hinges, and box locking devices (e.g., wedges and wedge seats).
Detachable Floor Design (Patented Innovation):
Some models feature a cargo box with a separate movable floor. Only the floor is lifted during unloading-reducing hydraulic system load-making it ideal for non-bulk cargo (e.g., containers).
II. Technical Features & Innovations
Reinforced Load-Bearing Structure:
High-strength steel (e.g., Baosteel manganese plate) welded frame girders with flanged hexagonal holes in the web plate enhance lightweighting and deformation resistance, increasing load surface lifespan by 30%.
Hot-dip galvanized girders provide 20-year corrosion resistance (e.g., for humid environments like Southwest China).
Lightweight Technology:
High-strength steel (e.g., Huayu U-shaped box), structural optimization (concave-convex cross beams), and localized weight reduction lower vehicle weight by 3 tons (e.g., curtain-sided semi-trailer: 6.5-ton tare weight), complying with axle-load regulations.
Enhanced Safety & Stability:
10 cm lower unloading height, 20 cm wider hinge base, and 10 cm increased girder spacing prevent rollovers.
Cab adopts integral rear-shift technology (500 mm impact displacement) for driver protection.
