Dongfeng KC cab assy C01 50M12-L1LEV0S for heavy-trucks

The cab’s frame is constructed from high-strength Q355 low-alloy steel, with a 2.0mm-thick outer panel and double-reinforced door pillars (3.5mm-thick steel plates) that boost torsional stiffness to 30,000 N·m/rad—30% higher than standard KC variants. Critical joints (roof-to-pillar, floor-to-frame) are welded via robotic MIG welding, with 100% ultrasonic flaw detection to eliminate weld defects. It also features a C01-exclusive front anti-collision beam (2.5mm-thick high-strength steel) that absorbs up to 40% of impact energy in frontal collisions, meeting Dongfeng’s DFM-S-015-2024 safety standard for heavy-duty cab structures

Tailored for extended driving shifts, the KC C01 cab assembly includes upgraded comfort features:

Driver’s Seat: A 8-way adjustable air-suspension seat (with lumbar support, seat heating, and ventilation) that reduces vibration transmission by 40%, minimizing fatigue during 10+ hour trips. The seat also has a weight-adjustment function (50-120kg) to fit diverse driver body types.Interior Space: A widened cabin design (2180mm internal width) with a flat floor (1200mm between seats) and overhead storage compartments (total capacity: 30L) for luggage or tools, plus a foldable passenger seat that converts to a small workbench.Climate Control: A dual-zone automatic HVAC system (heating capacity: 7kW, cooling capacity: 8500BTU/h) with 6 air vents (front + rear) and a PM2.5 air filter, maintaining a comfortable cabin temperature (-25℃ to +45℃) and clean air in harsh environments

The assembly is equipped with KC C01-specific functional features to support heavy-duty operations:

Instrument Panel: A 12.3-inch digital instrument cluster paired with a 10.25-inch touchscreen infotainment system, displaying real-time data (engine torque, fuel consumption, and tire pressure) and supporting truck-specific functions (e.g., cruise control adjustment, trailer brake monitoring).Electrical Convenience: 4 USB ports (2×2.4A fast-charging, 2×1A standard) and 2 12V power outlets (one in the dashboard, one in the overhead console) for powering GPS navigators, dashcams, and refrigerated storage boxes.Accessibility: Wide-opening doors (90° opening angle) with double-step assist rails (load capacity: 200kg) and anti-slip foot pads, plus a tilt-and-telescoping steering wheel (adjustable by ±8° in angle and 120mm in length) for easy entry/exit and optimal driving posture

The cab assembly is fully compatible with the Dongfeng KC C01’s National VI emissions-compliant engines (e.g., Yuchai YC6MK480-60, Xichai 6DL3-48E6) and integrates dedicated mounting brackets for emissions control components (DPF, SCR, and EGR cooler). It meets China’s GB 26512-2011 cab safety standards and GB 1495-2002 noise control standards—with in-cabin noise reduced to ≤70dB (at 60km/h) via a 8mm-thick sound-insulating floor mat and sealed door gaskets. Additionally, the cab’s exterior coating (electrophoretic primer + topcoat) achieves 800 hours of salt spray resistance (per GB/T 10125-2021), ensuring durability in coastal or high-salt road environments
