Dongfeng KL cabin assy 5000012-C31S0 for sale

The cabin’s core frame is constructed from high-strength Q460 steel (1.8-2.2mm thickness) with a reinforced “safety cage” structure—featuring double-layered front anti-collision beams, reinforced A/B/C pillars, and a rigid floor crossbeam system. This design meets China GB 26511-2011 and European ECE R29 cab crash standards, capable of withstanding a 30kN front impact force and a 2.5× vehicle weight rollover load without critical deformation. The steel surface undergoes a full-body electrophoretic coating (100μm thickness) followed by a polyester topcoat, achieving 500-hour salt spray resistance (no rust or peeling) to endure harsh environments like coastal roads or winter de-icing salts. Additionally, the cabin’s door hinges and latches use stainless steel components, ensuring smooth operation even after 100,000+ opening/closing cycles

Designed for long-haul driver comfort, the cabin assembly includes a range of pre-installed ergonomic features. It comes with a 6-way adjustable driver’s seat (manual or optional air suspension, with lumbar support and heating) and a 3-way adjustable passenger seat, both upholstered in wear-resistant PVC leather (resistant to oil and stains). The dashboard is integrated with a 7-inch digital instrument cluster (displaying speed, fuel level, and DTCs) and a 10-inch touchscreen infotainment system (supporting Bluetooth, GPS navigation, and reverse camera input)—all pre-wired to the cabin’s electrical harness. The cabin also features a dual-zone air conditioning system (with independent temperature control for driver/passenger sides) and 6 air vents (3 front, 2 side, 1 rear), maintaining a comfortable in-cabin temperature (22-26℃) even in extreme outdoor conditions (-30℃ to +45℃)

To minimize driver fatigue, the cabin assembly incorporates multi-layer noise and vibration control technologies. The cab floor is lined with 20mm thick sound-absorbing foam (density 40kg/m³) and a 5mm rubber damping pad, reducing road and engine noise by up to 30dB. The door panels include EPDM rubber sealing strips (double-layered, 18mm cross-section) that form an airtight seal, blocking wind noise at high speeds (≤68dB in-cabin noise at 90km/h, 15dB lower than standard cabins). The cabin is mounted to the chassis via 4 hydraulic shock absorbers (with 50mm stroke) that isolate 80% of frame vibrations (tested at 5-200Hz vibration frequencies), preventing discomfort from long-term driving on rough roads. Additionally, the windshield uses 4.2mm laminated glass with a sound-insulating interlayer, further reducing external noise penetration

This cabin assembly meets strict environmental and regulatory requirements, including China’s GB 18352.6-2016 (emission compatibility) and EU REACH (restriction of hazardous substances), ensuring no heavy metals (lead, mercury) or toxic chemicals in materials. It is also compatible with Dongfeng KL’s SCR (Selective Catalytic Reduction) system, with pre-reserved mounting space for emission-related sensors. For after-sales convenience, the assembly includes a detailed installation manual (with 3D diagrams of mounting points and wiring connections) and a 12-month warranty (covering defects in materials, such as paint peeling or component failure). Additionally, all replaceable parts (e.g., door handles, window regulators) are standardized to OEM specifications, allowing easy sourcing of spares from Dongfeng’s global parts network—reducing long-term maintenance costs for fleet operators
