Dongfeng KL truck parts electric Left door glass lifter 6104010-C3100

Built for reliable and effortless glass operation, this electric lifter features a high-performance drive system. It is equipped with a 12V permanent magnet DC motor (power 80W) that delivers a stable lifting speed of 8mm/s—30% faster than aftermarket lifters while maintaining smoothness. The cable-driven mechanism uses galvanized steel cables (breaking strength ≥1500N) guided by nylon pulleys with Teflon bushings, reducing friction by 45% and ensuring quiet operation (≤45dB, equivalent to a library environment). A built-in anti-pinch sensor (compliant with EU R147 standards) detects obstacles with 5N sensitivity, reversing the glass within 0.2s to prevent injuries. The lifter supports 50,000+ lifting cycles without speed degradation, far exceeding the industry standard of 30,000 cycles

Engineered for long-term reliability in harsh truck door environments, the 6104010-C3100 lifter adopts robust structural components. The motor housing is made of die-cast aluminum (ADC12 grade) with heat dissipation fins, reducing operating temperature by 20℃ and preventing overheating during continuous use. The cable drum and guide rails are fabricated from high-strength steel (Q235) with zinc-nickel alloy plating, passing 1500-hour neutral salt spray testing (ASTM B117) with no rust. The plastic components (pulleys, brackets) are made of glass fiber-reinforced PP (GF20), resisting deformation in temperatures from -40℃ to 85℃. This durability ensures the lifter operates normally in rain, snow, and dusty construction site conditions

Optimized to integrate multiple safety features, the lifter enhances both component protection and occupant safety. The anti-pinch system not only prevents injury but also reduces stress on the motor and cables, extending component life. A built-in overload protector cuts off power to the motor when the current exceeds 10A (e.g., glass jamming), avoiding motor burnout (repair cost up to $300). The lifter’s mounting bracket features a shock-absorbing rubber pad that isolates vibration from the door, preventing component loosening and noise. Additionally, the waterproof connector (IP67 rating) blocks rainwater from entering the electrical system, preventing short circuits and ensuring reliable operation in heavy rain

This electric glass lifter is designed for efficient installation and long-term cost savings for Dongfeng KL operators. The pre-assembled structure (motor + cable assembly + mounting bracket) allows a single technician to complete replacement in 60 minutes using only basic hand tools—no specialized calibration needed, as it auto-syncs with the door control module. The OE-compatible design eliminates compatibility issues common with aftermarket lifters, which often cause glass misalignment or control failure. The high-durability components reduce replacement frequency by 60%, while the 2-year/250,000km Dongfeng warranty guarantees performance. By ensuring reliable glass operation, it reduces downtime and maintenance costs, making it a cost-effective investment for fleets
