Dongfeng KL truck parts electric Right door glass lifter 6104020-C3100

Equipped with a 12V/24V (matching Dongfeng KL’s electrical system) permanent magnet DC motor, the lifter delivers a maximum torque of 8 N·m and a lifting speed of 8mm/s—powerful enough to raise/lower the heavy truck door glass (up to 5kg) smoothly, even in low-temperature environments (-40°C). The motor features a copper-wound armature and a heat-resistant commutator that prevents overheating during continuous operation (supports 5 consecutive lift/lower cycles without performance loss). A built-in reduction gearbox (gear ratio 1:40) converts high motor speed into controlled lifting force, ensuring the glass moves evenly without jerking. Unlike low-torque motors that struggle with thick truck glass or freeze in cold weather, this design guarantees reliable operation in all driving conditions, reducing driver frustration from stuck windows

Built to withstand the constant vibration and mechanical stress of truck operation, the lifter uses rugged, long-lasting materials. The lift arms and linkage rods are made of high-strength carbon steel (Q235 grade) with a zinc-plated coating, resisting rust and bending under the weight of the glass. The plastic components (glass brackets, motor housing) are crafted from glass-fiber-reinforced nylon (PA66-GF30), which endures temperatures ranging from -40°C to 120°C and resists wear from repeated movement. The lifter’s cable (where applicable) is made of galvanized steel with a PVC sheath, preventing fraying and reducing friction against guide pulleys. Unlike plastic-dominant lifters that break easily, this steel-reinforced design ensures the assembly operates reliably for 150,000+ km or 50,000+ lift/lower cycles

Engineered to protect the glass, lifter components, and users from damage, the assembly integrates dual safety features. An overload protection circuit in the motor cuts power if the lifter encounters excessive resistance (e.g., glass jammed by debris, frozen guide rails), preventing motor burnout or linkage bending. For user safety, an anti-pinch function (meeting ECE R116 standards) detects obstacles (e.g., fingers, tools) during glass lowering, reversing the glass upward by 50mm within 0.5 seconds to avoid injury. The anti-pinch system uses current sensing technology that responds to even slight resistance (as low as 50N), ensuring sensitive protection without false triggers. Unlike basic lifters without safety features, this design reduces maintenance costs from component damage and minimizes safety risks for drivers/technicians

Designed for efficient replacement by fleet technicians or DIY owners, the lifter simplifies installation and upkeep. It includes all necessary hardware: 6 OEM-matched mounting bolts (M5×12mm), a plug-and-play electrical connector, and pre-lubricated guide rails—no additional parts or lubrication required. Installation takes 45–60 minutes with standard hand tools (socket wrench, trim panel tool), as the lifter aligns perfectly with the door’s existing glass brackets and wiring. For maintenance, the lifter’s moving parts are pre-lubricated with lithium grease that lasts for the assembly’s lifespan, eliminating the need for periodic re-lubrication. Each unit undergoes strict testing: load-bearing trials (120% of rated weight), cycle testing (10,000 lift/lower cycles), and safety function verification. Backed by a 18-month warranty against manufacturing defects (e.g., motor failure, linkage breakage, anti-pinch malfunction), it provides Dongfeng KL truck owners with reliable power window operation and long-term peace of mind
