Dongfeng KL cab shell 50M14-C35GY23#8A made in china

Constructed with high-strength low-alloy (HSLA) steel sheets (grade Q345B) with a thickness of 1.5-2.0mm, this cab shell offers exceptional structural rigidity and impact resistance. The key stress-bearing areas—including the front anti-collision beam, roof support pillars, and floor crossbeams—are reinforced with double-layer steel plates and welded using robotized CO₂ gas shielded welding technology, which ensures weld strength (tensile strength ≥ 500MPa) and reduces the risk of cracks under heavy loads or collisions. The steel surface undergoes a full-body electrophoretic coating process (coating thickness 80-120μm) followed by a topcoat, providing excellent corrosion resistance—tested to withstand 500 hours of salt spray testing without rusting, making it suitable for long-term use in humid, coastal, or high-salt environments

The cab shell is designed with a focus on driver comfort and space utilization, featuring a spacious internal cabin volume of 12.5m³—providing ample headroom (1.9m) and legroom (1.2m) for drivers of different heights. The sloped front windshield design not only reduces aerodynamic drag (lowering fuel consumption by approximately 3% compared to flat windshields) but also expands the driver’s field of view (horizontal viewing angle up to 120°). The cab shell also reserves precise mounting positions for original Dongfeng KL interior components, such as the driver’s seat (with adjustable height and backrest angle), dashboard, air conditioning system, and storage compartments (including overhead lockers with a total capacity of 50L). Additionally, the rear wall of the cab shell is pre-designed with holes for installing a sleeper berth (optional), catering to the long-distance driving needs of truck drivers

To enhance driving comfort, the cab shell incorporates a multi-layer sealing and noise reduction structure. The door frames are equipped with EPDM rubber sealing strips (with a cross-sectional area of 15mm × 8mm) that form a tight seal with the door panels, effectively preventing rainwater, dust, and cold air from entering the cabin. The roof and floor of the cab shell are lined with sound-absorbing cotton (thickness 20mm, density 30kg/m³) during the manufacturing process, which reduces external noise (such as engine noise, road noise, and wind noise) by up to 25dB—lowering the in-cabin noise level to ≤ 65dB when the truck is running at 90km/h. The front wall of the cab shell also features a heat-insulating layer (made of polyurethane foam with a thermal conductivity of ≤ 0.03W/(m·K)), which helps maintain a stable internal temperature, reducing the workload of the air conditioning system and improving energy efficiency

This cab shell is delivered in a semi-finished state ready for component assembly, with all necessary mounting points, wiring harness holes, and pipeline holes pre-drilled and positioned according to the original Dongfeng KL design. The package includes a detailed assembly manual that marks the location of each mounting hole (with corresponding bolt specifications, such as M10×25 for seat mounting) and the routing of wiring harnesses, simplifying the assembly process for maintenance workshops. The cab shell fully complies with China’s GB 26511-2011 “Safety Requirements for Heavy-Duty Truck Cabs” and the European ECE R29 regulation for cab crash safety, passing tests such as front impact, side impact, and rollover resistance. It also meets the national environmental protection standard GB 18352.6-2016 for automotive emissions, ensuring that the cab shell is compatible with the Dongfeng KL’s emission control system and meets market access requirements
