Dongfeng GX truck spare parts cab shell 50M14-C62GYA5 in stocked

Built with a “safety cage” design, this cab shell prioritizes driver protection through multi-layer structural reinforcement. The frame uses high-strength steel (Q960) for key stress areas (A-pillars, B-pillars, roof beam), achieving a tensile strength of 960MPa—40% higher than conventional cab steel. The floor adopts a 3-layer composite structure (base steel + reinforcing ribs + anti-fatigue plate) that withstands 10-ton impact loads without deformation. It meets ECE R29-03 rollover safety standards, maintaining a survival space for drivers even when the cab rolls over at 30km/h. Additionally, the front buffer beam integrates energy-absorbing structures that reduce impact force by 50% in frontal collisions, significantly improving accident survival rates

The cab shell achieves an optimal balance between lightweight and rigidity through advanced material application and structural optimization. It uses a combination of Q960 high-strength steel (35% of total weight) and 6061 aluminum alloy (for non-stress panels), reducing overall weight by 18% compared to traditional all-steel cabs—directly improving fuel efficiency by 5-7%. The shell undergoes CNC precision stamping and robotic welding (weld seam strength ≥500MPa), ensuring uniform structural rigidity and minimizing vibration during driving. Finite element analysis confirms it maintains structural integrity under 30g vibration loads (5-2000Hz) and resists torsional deformation even on uneven roads, enhancing driving stability

The cab shell features an aerodynamically optimized contour designed via computational fluid dynamics (CFD) simulation. The sloped front windshield (25° angle), streamlined roof deflector, and curved side panels reduce wind resistance by 25% at high speeds (80-100km/h), lowering wind noise by 15dB and further improving fuel economy. The shell’s weatherproof performance is enhanced by EPDM rubber seals (IP67 rating) around doors, windows, and ventilation ports, preventing water and dust intrusion even in heavy rain or dusty mining environments. The surface undergoes cathodic electrophoretic coating and powder coating (total thickness 120μm), passing 2500-hour salt spray testing to resist corrosion in coastal or de-iced road conditions

Designed for both factory assembly and after-sales maintenance, the cab shell features a user-friendly structure with precise positioning and mounting systems. All pre-punched holes (for interior components, wiring, and exterior parts) have a tolerance of ±0.1mm, ensuring accurate alignment with accessories during installation. The shell integrates modular mounting points for air conditioners, refrigeration units (for cold-chain trucks), and safety systems (airbags, collision sensors), reducing assembly time by 30% compared to non-OE shells. For after-sales service, the shell’s detachable front and side panels allow easy access to engine and chassis components, cutting maintenance time by 45%. Backed by a 3-year/300,000km warranty, it ensures long-term reliability for heavy-duty operations
